627efed7-ef6a-4a14-ba3c-f06944ff4f80 CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: ASBETER WEBSITE: ASBETER.COM SECTOR : BUILT ENVIRONMENT PUBLISHED: 26 NOVEMBER 2025 TAGS: CIRCULARECONOMY, ASBESTOS, SUSTAINABLECONSTRUCTION, HAZARDOUSWASTE, CIRCULARMANUFACTURING, BUILTENVIRONMENT, GREENBUILDING, WASTEMANAGEMENT, CLEANTECH, INNOVATION, CONSTRUCTION, MATERIALRECOVERY The Challenge Asbestos-cement products are one of the most persistent legacy hazards in the built environment, combining high health risks with difficult end‑of‑life management. Asbestos refers to a group of naturally occurring mineral fibres formerly prized for their durability and heat resistance. Throughout the twentieth century, these qualities led to the widespread use of asbestos in building materials for the likes of roofing, cladding, and pipes. ( World Health Organization, 2024 ). Exposure to airborne asbestos fibres causes fatal diseases, including lung and larynx cancer and mesothelioma, leading to over 200,000 deaths annually worldwide ( World Health Organization, 2024 ). Despite bans in many countries, global asbestos mining continues, with around 1.3 million tonnes produced in 2023 ( UNEP, 2024 ). Many countries still rely on landfilling asbestos-containing materials, which locks future liability into the ground and occupies scarce disposal capacity. Asbestos-cement products remain a persistent legacy issue in Ireland’s built environment, where many pre-2000 buildings still contain asbestos materials posing serious public health risks ( Health and Safety Authority, 2017 ). Despite being banned since 2004, asbestos fibres continue to threaten workers and residents during refurbishment or demolition activities unless tightly controlled ( OHSS, 2025 ). Ireland’s asbestos waste is classified as hazardous and requires special handling and disposal at EPA-licensed facilities. However, domestic landfill capacity for asbestos is limited, often requiring export or transfer to facilities overseas ( EPA, 2021 ). Ireland is currently preparing for the EU Asbestos Directive’s implementation in Dec 2025, which will further strengthen exposure limits, monitoring, and training requirements to improve worker safety ( EHS International, 2025 ) A Circular Solution Founded in 2018 in the Netherlands, Asbeter developed its AC Minerals process and commercialized it in 2022 to safely treat asbestos cement by alkaline dissolution ( Asbeter, 2024 ). The AC Minerals process involves breaking down asbestos cement waste by shredding and milling it into small fragments inside a sealed environment with water. The resulting slurry is then heated below 100C which creates a chemical reaction in which the asbestos fibres chemically transform until they are completely neutralized and no longer pose a hazard ( BBC Future, 2024 ). The process recovers valuable raw materials such as calcium silicate and calcium carbonate from the treated waste, which can then be reused in industries like cement and concrete manufacturing. This innovative technique aims to safely and effectively transform hazardous asbestos waste into reusable materials, addressing a major challenge in global asbestos disposal ( Asbeter, 2025 ). This approach offers a promising alternative to hazardous asbestos landfill, enabling recycling into circular construction inputs, reducing landfill reliance and health risks. Climate Impact Asbeter was issued an end-of-waste certificate by the Dutch Environment Agency ( DCMR, 2023 ) and the independent testing agency, Det Norske Veritas, also issued a verification statement confirming that their process completely dissolves asbestos fibres from asbestos-containing materials, resulting in an asbestos-free residue ( DNV, 2023 ). Asbeter plans to build a plant capable of processing 25,000 tonnes a year, growing to 75,000 tonnes a year ( BBC Future, 2024 ). By safely neutralizing asbestos fibres and producing a non-hazardous residue, the AC Minerals process eliminates the need for hazardous asbestos waste landfilling. If implemented in Ireland, a similar solution could significantly reduce the environmental risks associated with asbestos disposal while keeping valuable mineral materials in circulation. Moreover, by making the waste safe, it could substantially lower the high shipping and remediation costs currently required to transport hazardous asbestos waste off-island for disposal, leading to economic and environmental benefits through more local processing and circular reuse. Replicability The green building materials market was valued at USD 285.89 billion in 2024, projected to grow by 8.5% annually through 2030 ( Grand View Research, 2025 ). Asbeter’s method illustrates a replicable circular economy solution to manage legacy asbestos waste while producing low-carbon construction feedstock for the built environment’s transition ( Asbeter, 2024 ). Addressing asbestos is critical: asbestos exposure accounted for 78% of occupational cancers in the EU in 2019, with approximately 70,000 workers still exposed today ( European Commission, 2022 ). This underscores the urgent need for safe and scalable asbestos waste management solutions. Another company working on a circular solution for asbestos is Thermal Recycling in the UK. The company uses high-temperature processing to convert asbestos cement into inert mineral materials, achieving end-of-waste status and enabling reuse. ALL CASE STUDIES

ab85e4a6-f838-4371-b1cb-0cee6b3a87ef CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: THE NATIONAL MANUFACTURING INSTITUTE SCOTLAND (NMIS) WEBSITE: NMIS.SCOT SECTOR: RESEARCH SERVICES PUBLISHED : 29 JANUARY 2026 TAGS: CIRCULARMANUFACTURING, REMANUFACTURING, MATERIALEFFICIENCY, NETZERO, INDUSTRIALINNOVATION, DIGITALPRODUCTPASSPORT, SERVITISATION, MANUFACTURINGSKILLS, VALUERETENTION, SUPPLYCHAINRESILIENCE In the second week of September 2025, a delegation of CIRCULÉIRE members and staff was invited to Glasgow, Scotland, by Zero Waste Scotland to meet Circular Economy Industry Pioneers and Stakeholders from the Scottish Ecosystem. On Tuesday, September 9 th , our delegation visited the National Manufacturing Institute Scotland, a publicly funded initiative that champions and derisks innovation in the manufacturing industry. This case study is part of a special series to transfer knowledge and learnings to Circular Economy Pioneers in the Irish Ecosystem. The Challenge Scotland’s economy runs almost entirely on virgin materials; 98% of the materials it uses come from freshly extracted resources. In 2018, this added up to 21.7 tonnes per person, nearly twice the global average (Circle Economy et al., 2022) . This “take, make, dispose” approach is costing the planet. Worldwide, the extraction and processing of materials account for half of all greenhouse gas emissions and over 90% of biodiversity loss and water stress ( UNEP, 2019 ). The situation is getting worse; in 2018, 9.1% of materials were recirculated globally ( Circle Economy, 2018 ), but this figure has since fallen to just 6.9% in 2025 ( Circle Economy, 2025 ). Scotland contributes to this impact; it imports significant quantities of materials and goods while also extracting fossil fuels domestically, which makes the country’s true carbon footprint 42% larger than what occurs within its geographic borders (Circle Economy et al., 2022) . If Scotland wants to cut its environmental impact meaningfully, it needs to rethink how materials are used. Moving towards a circular economy offers a clear path forward. Circle Economy’s 2022 Circularity Gap Report Scotland estimates that adopting circular practices in the manufacturing sector alone could cut the country’s material footprint by roughly 11% and lower emissions by nearly 5%. The Circular Solution The National Manufacturing Institute Scotland (NMIS) is key to reshaping how Scotland makes and uses materials. By helping manufacturers embrace new technologies and innovate with less risk, NMIS is guiding the industry towards a more circular future. The UK government aims to achieve net-zero carbon emissions by 2045 to 2050, and NMIS is crucial to this effort. NMIS’s state-of-the-art facility in Renfrewshire is home to their Digital Factory, Manufacturing Skills Academy and Collaboration Hub. They also operate a second site in Renfrewshire and have a presence in Sheffield and North Ayrshire. Operated by the University of Strathclyde and supported by the Scottish Government and other public partners, it serves as a meeting point where innovation and sustainability are combined. The ReMake Value Retention Centre is NMIS’s spearhead project on developing remanufacturing solutions across industries. This £10+ million project focuses on sectors critical to national infrastructure, such as aerospace and power generation, and aims to keep products at their highest value instead of sending them to landfill. Since its opening, NMIS has supported over 700 research and development projects and engaged with more than 2,000 small and medium-sized enterprises. They have also delivered over 365 free training opportunities to help businesses build the skills needed to decarbonise the economy ( HVM Catapult, n.d. ). Climate Impact Around 70% of direct industrial emissions come from the extraction and processing of the basic raw materials ( Bashmakov et al., 2022 ). By remanufacturing parts to their original, or even improved, performance, these emissions stay locked in, cutting environmental impact dramatically. A circular supply chain also reduces costs and lead times while strengthening industrial resilience in critical sectors. NMIS’s ReMake Value Retention Centre is helping companies make this shift to remanufacturing by addressing challenges across technology, business models, policies, standards, culture, skills, and investment. Momentum is building with new EU rules requiring nearly all products sold in the EU to carry a Digital Product Passport (DPP) . A DPP contains detailed data on materials, processes, and emissions. ReMake helps firms not only collect and manage this data but also turn it into value. With a DPP, businesses can interact more effectively with customers, sell approved spare parts, and share repair manuals or service records. ReMake is shifting the DPP from a compliance burden to a tool for monetisation and stronger customer relationships (Munawar, 2025) . ReMake also supports firms in developing new business models. Instead of one-off product sales, companies can move towards servitisation. This allows them to build long-term service relationships backed by remanufacturing and data-driven insights. This business model innovation, backed by technology, can extend product lifecycles, generate recurring revenue, and keep customers engaged (Fitzpatrick, 2025) . The National Manufacturing Institute of Scotland, through ReMake, is helping redesign the future of manufacturing in Scotland and beyond.

8c3cab76-fc07-43ee-8b7f-cc1e19ca85c6 CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: NORSK OMBRUK WEBSITE: NORSKOMBRUK.NO SECTOR : WEEE PUBLISHED: 25 SEPTEMBER 2025 TAGS: REMANUFACTURING, WEEE, EWASTE, WHITEGOODS, EXTENDEDPRODUCERRESPONSIBILITY, EPR, APPLIANCEREPAIR, RESOURCEEFFICIENCY The Challenge Waste Electrical and Electronic Equipment (WEEE) is the world’s fastest-growing waste stream, increasing faster than global population growth. In 2022, approximately 14.4 million tonnes of electrical and electronic equipment were placed on the market in the EU, with an official WEEE collection rate of around 40% according to the European Environment Agency ( EEA, 2025 ). This rate remains below the EU’s 65% target established under the WEEE Directive. In Ireland, 63,946 tonnes of WEEE were collected in 2023, reflecting a collection rate of approximately 43.6%, a significant drop from 51.2% in 2022 and 63.8% in 2021 ( EPA, 2025 ). WEEE is associated with major environmental and health risks due to toxic material content, energy consumption in production, and improper disposal. In 2020, WEEE contributed an estimated 580 million metric tonnes of CO2e emissions globally ( Singh and Ogunseitan, 2022 ). This makes effective circular management essential. The Circular Solution Norsk Ombruk AS is a Norwegian Remanufacturing company established in 2013, certified for Extended Producer Responsibility (EPR). EPR is a policy approach that makes producers responsible for managing the environmental impacts of their products throughout the product lifecycle, including waste collection, recycling, and disposal at end-of-life. Discarded kitchen, laundry, and bathroom appliances make up the majority of global e-waste, accounting for around 60%, with washing machines, clothes dryers, dishwashers, and electric stoves contributing approximately 11.8 million tonnes annually ( Earthshine, 2024 ). Norsk Ombruk extends the useful life of household electrical goods such as refrigerators, washing machines, stoves, dishwashers, and dryers, playing a leading role in Norway’s shift toward a more circular electronics sector. Norway’s EPR policies have fostered circular business models like Norsk Ombruk’s, which partners with leading electronics producers (e.g., Ikea , Elkjøp ), municipalities, and second-hand shops to collect used household appliances ( Elektronikkbransjen, 2022 ). Once Norsk Ombruk receives a product, it is inspected, barcoded, and entered into a quality control system. About 48% pass detailed diagnostics and are repairable, while non-repairable products are dismantled for parts recovery and the remaining materials are recycled. Repairable units are cleaned, assigned a tailored work schedule, refurbished or upgraded by certified skilled technicians, then rigorously tested to ensure quality. Once complete, products undergo a final hygienic cleaning before being dispatched to major retailers or sold via second-hand dealers or Norsk Ombruk’s own Sandefjord shop at around half the price of a new model. This collaborative, efficient workflow extends product and brand life while maximising resource use and environmental benefits ( Earthshine, 2024 ). A two-year guarantee on all remanufactured goods provides consumers with confidence and access to affordable, high-quality appliances. In 2016 alone, Norsk Ombruk remanufactured over 12,300 appliances and reported annual sales of €1.8 million, and by 2024 the company had extended the life of more than 100,000 products that would otherwise have become waste ( Earthshine, 2024 ). Success in Norway has led to expansion into other European markets, including the establishment of a similar business in Denmark under the name Resirk ( Elektronikkbransjen, 2022 ). Climate and Societal Impact Remanufacturing electrical appliances provides significant climate and resource benefits by displacing demand for new goods, reducing waste, and promoting resource efficiency. According to independent analysis, Norsk Ombruk’s activities in 2016 saved 2,713 tonnes of embedded CO 2 , nearly 13 million kWh of embedded energy, and €2.3 million in raw material value—resulting in cumulative benefits valued at €9.4 million ( Earthshine, 2024 ). These savings translate to lower product costs for consumers, which is especially meaningful for lower-income households. The business model also eases the regulatory burden for retailers and municipalities while supporting national circularity targets. Replicability The European remanufacturing market is projected to reach €90 billion by 2030 ( ERN, 2024 ). Regulations such as the EU Waste Framework Directive and the Ecodesign for Sustainable Products Regulation are strengthening producer responsibility and incentivising circularity across Europe ( ERN, 2024 ). Remanufacturing initiatives like Norsk Ombruk offer a scalable, proven pathway to cut emissions, retain value, and deliver social and economic wins for Ireland as it advances toward its national circular economy targets. Other examples of Irish remanufacturers include: Glen Dimplex Ireland repair and refurbish white goods and household appliances, including cooking appliances, water heaters, TVs, and electric fires. They use spare parts from returned appliances to refurbish or repair other units, reducing the need for new parts ( WEEE Ireland, 2024 ). GreenIT are one of Ireland’s pioneers in IT remanufacturing and circular economy, offering remanufactured IT devices with warranty and comprehensive quality assurance ( CIRCULÉIRE, 2025 ) Finline Furniture take back and remanufacture their pre-loved high-quality sofas offering them at an affordable price and a 20 year guarantee ( CIRCULÉIRE, 2025 ). A Note on the Differences Between Repair, Refurbishment & Remanufacture Repair is the most basic intervention, focused on fixing a specific fault to get a product back into working order. This process typically involves minimal disassembly and only addresses the failed part without assessing the overall condition of the item. The goal is to restore function, not to improve the product's lifespan or appearance. Refurbishment goes a step further than repair. It involves restoring a used product to a functional, but not necessarily "like-new," condition. The focus is on fixing obvious faults and improving its cosmetic appearance. Parts are repaired or replaced as needed, but the product is not completely disassembled. A refurbished item will often have a limited warranty and may not meet original performance specifications. Remanufacture is the most rigorous and comprehensive process. It involves disassembling the product completely, inspecting all individual components, and replacing or restoring worn-out or obsolete parts with a combination of reused, repaired, and new parts. The goal is to return the product to a like-new or better-than-new condition in terms of performance, appearance, and quality. A remanufactured product typically comes with a new warranty that is equivalent to or better than the original product's warranty. ALL CASE STUDIES

05814e72-2073-4602-bc35-9357c56238a0 CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: CPW & HGP ARCHITECTS (BEN AINSLIE RACING HQ) WEBSITE: CPW & HGP ARCHITECTS SECTOR : BUILT ENVIRONMENT PUBLISHED: 02 JULY 2025 TAGS: CIRCULAR DESIGN, CIRCULAR PROCUREMENT, LIFE_CYCLE ANALYSIS, WASTE HIERARCHY, RECYCLED MATERIALS, RENEWABLE ELECTRICITY, WATER EFFICIENCY, RESOURCE EFFICIENCY About Ben Ainslie HQ Ben Ainslie Racing (BAR) headquarters is a building located in Portsmouth in England. It was built to house the British sailing team competing in the America’s Cup. The construction work started in July 2014, with the new facility becoming fully operational in late 2015. The project faced demanding targets from the local government’s planning consent process, since it had to demonstrate its environmental benefits. In the end these initial challenges facilitated the adoption of circular principles in the procurement process, allowing better end-of-life consideration and sourcing of materials. The Challenge Construction and building operations account for 33% of global greenhouse gas (GHG) emissions and 40% of global energy consumption, owing to the use of equipment, transportation, and building materials manufacturing ( Sizirici et al., 2021 ). In Ireland, construction and demolition generate eight million tonnes of waste ( Nugent, 2023 ), which is more weight than that of the Great Pyramid of Giza in Egypt. Furthermore, the vast majority of this material is not reused or recycled ( Nugent, 2023 ). More construction is needed as the population grows and urbanisation expands. However, to mitigate GHG emissions, novel, sustainable, and resource efficient construction methods are required. The Circular Solution The tender for the BAR HQ was based on creating the first building in Portsmouth with a Building Research Establishment Environmental Assessment Method (BREEAM1) ‘Excellent’ rating. This was a requirement for the local government planning consent. Using Building Information Modelling (BIM), the design team was able to conduct a life cycle analysis of design decisions while also giving informed options for in-use performance monitoring. This promoted circular thinking in the acquisition of construction materials and products. Following the waste hierarchy, the first principle of the procurement approach was to reduce the impact of the materials energy and water. This approach started with the demolition and recycling of existing materials, e.g. concrete, on the site. The approach also considered where impacts would occur across the whole life of the building. All the key specifications were aimed at achieving the BREEAM Excellent rating. The award criteria was based on a combination of environmental performance and cost, depending on the construction element being procured. Climate Impact The collaboration between designers and product suppliers during the BAR HQ project demonstrated the importance of engaging suppliers early. This ensured that solutions offered through the tender stage met environmental performance, as well as cost levels. In terms of environmental benefits, much importance was given to fully or almost fully recyclable and recycled materials. For instance: 100% of the demolition concrete was reused in the foundations; Over 97% of all demolition materials from the site were recycled; 100% of the steelwork materials are recyclable if the building is dismantled; 100% of the wall cladding is recyclable ( Jones et al., 2017 ). Importance was also given to energy and water efficiency: 100% renewable electricity; 1200 litre tank for harvesting rainwater; 25% improvement in water efficiency over standard building regulations. An estimated €2 million to €2.7 million worth of savings were achieved through sustainability measures ( Jones et al., 2017 ). Replicability Important factors to consider in projects with environmental performance targets are deadlines, costs and secondary material supply / availability ( Jones et al., 2017 ). Considering the conceptual and design phases of buildings rely on bids based on costs and CO2 emissions, some examples that are worth mentioning include: JLL’s Manchester office , where upskilling a real estate firm’s staff was the key to embed circular principles into design, procurement and fit-out to showcase how circularity can be brought into an office environment. UN City in Copenhagen , where the new UN hub presented a key opportunity to embed sustainable development and circularity in the building process.

19c8a8d5-aefd-49f6-9c2d-16d77324d22a CIRCULÉIRE MEMBER CASE STUDY COMPANY: HaPPE EARTH WEBSITE: HAPPEEARTH.COM SECTOR : MEDTECH PUBLISHED: 06 AUGUST 2025 TAGS: GREENHEALTHCARE, PPEWASTE, INNOVATION, SUSTAINABLEHEALTHCARE, MEDTECH, CIRCULARHEALTHCARE, ESG, COMPOSTABLE, BIOECONOMY, WASTEMANAGEMENT The Challenge Through its vitally important role in the protection of human health, the global healthcare sector generates an enormous and complex waste stream. If the global healthcare sector were a country, it would rank as the fifth-largest contributor to global CO₂ emissions, responsible for over 5% of total emissions, surpassing those from aviation or shipping sectors ( MedTech Europe, 2024 ). One-third of the carbon emissions generated by the healthcare sector, and most of its waste comes from medical devices ( Boston Consulting Group, 2024 ). Ninety percent of medical device waste primarily consists of single-use devices ( Health & EY, 2024 ). During the COVID-19 pandemic, medical waste became particularly visible, especially concerning Personal Protective Equipment (PPE). PPE is classified as any device or appliance designed to be worn or held by an individual for protection against one or more health and safety hazards ( HSA, 2025 ). Globally, an estimated 129 billion face masks and 65 billion gloves were used every month ( Prata et al., 2020 ). Typically, PPE is incinerated, and none is sent to landfill. However, during the pandemic, incinerators were so overrun that many countries were forced to send waste to landfill ( BMJ, 2021 ). By 2021, more than 8,000,000 tonnes of pandemic-associated plastic waste was generated globally, with more than 25,000 tonnes entering our oceans ( PNAS, 2021 ). An estimated 73% came from hospitals ( PNAS, 2021 ). PPE is an unquestionably necessary tool for saving lives. It prevents the spread of pathogens and infections and protects both frontline healthcare workers and patients. However, PPE such as face masks, gloves, and gowns are commonly manufactured from plastics such as polypropylene, polyurethane, polyacrylonitrile, polyethylene, and polyethylene terephthalate which can take as long as 450 years to decompose ( BMJ, 2021 ). Even when incinerated, PPE still releases greenhouse gases and contributes to air pollution ( Kumar et al., 2020 ). The challenge, therefore, is not to eliminate this essential equipment but to fundamentally redesign its lifecycle. The Circular Solution in Practice HaPPE Earth is an Irish company and CIRCULÉIRE member, founded in 2021. They make medically approved compostable PPE aprons from sustainably sourced, proprietary bio-resins. Bioresins are a type of polymer derived from renewable sources such as plants, cellulose, sugars, and other biological materials, instead of traditional petroleum-based sources ( Verde Bioresins, 2025 ). HaPPE Earth’s aprons are used the same as standard petroleum-based PPE aprons, but instead of being thrown away after use, they are sent to HaPPE Earth’s onsite medical biodigester system. The biodigester is offered as a first-of-its-kind Sustainable-Consumables-as-a-Service (SCAAS) business model and requires no capital investment from the healthcare service provider. The PPE aprons are composted alongside the healthcare provider’s food waste, where they break down in days in HaPPE Earth’s industrial composting process, resulting in a valuable, pathogen safe, nutrient-rich fertilizer. In addition, HaPPE Earth offers a real-time data monitoring tool allowing healthcare providers to track their plastic waste and CO 2 reduction and capture food waste data for use in their ESG reporting. The service is provided with a dedicated account management team to help with software integration and training, and technical support throughout the process. HaPPE Earth estimates the compostable apron and digestion system uses 75% less carbon emissions than standard single use aprons ( Health Innovation Hub Ireland, 2023 ). By managing waste on-site, the system saves on carbon emissions from transport while simultaneously preventing waste from entering waterways and avoiding air pollution from incineration. Furthermore, HaPPE Earth estimates their waste re-direction service can save the Irish Health Service approximately EUR €400,000.00, and reduce 8,000 tonnes of carbon emissions each year, all while eliminating PPE plastic waste. HaPPE Earth’s aprons are being trialled in over 20 hospitals in Ireland. However, any sector that uses PPE can use the HaPPE system – including pharmaceuticals, medical device industries and food preparation. Replicability Biodegradable and compostable PPE options are growing across Europe and North America, alongside trials of systems to digest and decompose the products effectively. Some notable examples of companies working to tackle the use of PPE in the healthcare sector include: Revolution-Zero focus on reusable alternatives to medical textiles, including isolation gowns, aprons, transfer sheets, curtains, and warm-up jackets. They offer direct purchase options or Product as a Service models, and offer software for operations, regulatory compliance, asset tracking and environmental reporting. AmorSui – offer a reusable line of PPE made from premium, machine washable materials. Their fabrics are recyclable, and they are currently developing a take-back programme and subscription model to fully align with their circular economy principles. ALL CASE STUDIES

a2ad675a-3d2a-4cc8-a7c1-5ea94d4f5d0d CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: IKEA WEBSITE: IKEA.COM SECTOR : BUILT ENVIRONMENT PUBLISHED: 14 JULY 2025 TAGS: RETURN, REUSE, RECYCLE, TAKE-BACK, SECOND LIFE, FURNITURE About IKEA IKEA is a home furnishing retailer founded in Sweden in 1943. As of July 2025, there were 486 stores worldwide, serving millions of customers. IKEA has been measuring their climate footprint and setting goals to minimise their environmental impact since the 2016 financial year (FY). The Challenge Every year, 10 million tonnes of furniture is thrown away by businesses and consumers across Europe, and most of this either ends up in landfill or is incinerated ( Forrest et al., 2017 ). The fast furniture industry is wasteful, resource-intensive and polluting. In the EU, furniture waste accounts for more than 4% of the total municipal solid waste (MSW) stream ( Forrest et al., 2017 ). According to IKEA’s FY24 Sustainability Report, their climate footprint is estimated to be equivalent to 21.3 million tonnes CO2 (IKEA, 2024 ). This represents a decrease of 5% compared to their FY23 report and 28% compared to their FY16 baseline but it’s still equivalent to approx. 5.6 coal-fired power plants’ emissions in a year ( EPA.gov, 2025 ). IKEA’s report also highlights that the majority of their climate footprint comes from raw material extraction and processing (52%) and their product use in customers’ homes (17%), which includes the energy consumption of lighting and appliances over the product’s lifetime (IKEA, 2024 ). The Circular Solution in Practice IKEA’s Buy Back & Resell Programme is designed to increase the number of times a piece of furniture is used before being recycled or sent to the landfill. IKEA buys back eligible preloved items from customers and resells these good quality second-hand pieces in the store’s Circular Hub section. Aside from second-hand items, the Circular Hub also offers ex-display products and discontinued furniture. To avail of this service, customers can fill out a form on IKEA’s website, to estimate the furniture’s buy-back value. Then they must bring their assembled IKEA furniture, together with the estimate, to an IKEA store. An IKEA worker will inspect the furniture before accepting it and giving the final agreed value as an IKEA gift card. The Buy Back Program is available in 28 countries, including Ireland, the United Kingdom, the United States of America, Canada, Japan and Italy. Impact The Buy-back scheme helps IKEA in cutting their carbon footprint by reducing the amount of virgin raw material inputs required for their products. This can be fulfilled through closing the product loop by facilitating appropriate recycling after multiple uses. In addition, this scheme can contribute to promote the repair concept, by making all the different components of furniture available for purchase separately. Sometimes, the smaller parts (such as dowels, screws, washers, etc.) can be obtained free of charge at the stores. Furthermore, through this scheme, accessible and affordable furniture will be available for low-income households. During IKEA's 2024 Buyback Friday campaign alone - an alternative to Black Friday - almost 55,000 IKEA products were returned to stores for resale (IKEA, 2024 ) . Replicability The European Union (EU) manufactures almost one-quarter of the world’s furniture, constituting an €84 billion market ( Forrest et al., 2017 ). Consumers are becoming more concerned about the environmental impact of the goods they buy. Moreover, government regulations such as the EU Eco-design for Sustainable Products Regulation (ESPR ) are pushing for eco-design criteria for products to greatly enhance their circularity, energy performance, and other aspects of environmental sustainability. Businesses will be required to provide product information from conception to end-of-life for almost all physical goods placed on the EU market. IKEA is serving as an industry pioneer in circular concepts by offering its Buy Back Programme. Businesses can be drawn to this scheme because it can increase profitability by decreasing the cost of production. Furthermore, it can be replicated to a variety of industries such as home appliances, electronics, and textiles. Among the Irish stores in the circular furniture industry are: Finline Furniture , take back old Finline sofas and give them a makeover. reducing the number of sofas going into landfill. Their upcycled sofas are striped down, re-padded, re-sprung, re-foamed and re-upholstered before being resold good-as-ne w. for a fraction of the price. Rediscover Furniture , is a furniture restoration and upcycling social enterprise housed at the Rediscovery Centre in Ballymun, Dublin. Walsh’s Furniture Repair & Assembly specialises in in repair of upholstery, leather, timber, and furniture assembly. ALL CASE STUDIES

42190427-b090-430f-90dc-e30d21bfa7df CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: RENEWABLE PARTS LTD. WEBSITE: RENEWABLE-PARTS.COM SECTOR: ENERGY DATE PUBLISHED: 16 JANUARY 2026 TAGS: WINDENERGY, WINDTURBINES, REMANUFACTURING, SUPPLYCHAIN, RENEWABLEENERGY, COMPONENTREUSE, DECOMMISSIONING, CARBONSAVINGS, MATERIALRECOVERY In the second week of September 2025, a delegation of CIRCULÉIRE members and staff was invited to Glasgow, Scotland, by Zero Waste Scotland to meet Circular Economy Industry Pioneers and Stakeholders from the Scottish Ecosystem. On Tuesday, September 9 th , our delegation visited Renewable Parts, a supply chain refurbishment and remanufacture specialist in the wind energy industry. This case study is part of a special series to transfer knowledge and learnings to Circular Economy Pioneers in the Irish Ecosystem. The Challenge The wind energy industry is experiencing rapid growth. In Ireland, wind power’s share of electricity supply has more than doubled in the last decade. It now provides 34% of Ireland’s electricity supply, second only to natural gas at 44% (SEAI, 2024) . Wind has very low emissions; about 13 grams of CO 2 per kilowatt-hour (NREL, 2001) , which mainly comes from the materials, manufacturing, and construction of the wind turbines. Once in operation, a wind turbine produces virtually zero emissions. In comparison, natural gas emits 486 grams per kilowatt-hour (NREL, 2001), making wind 97% cleaner. While this represents a significant leap forward, the industry still faces challenges. How can we make the materials, manufacturing, and construction of wind turbines more sustainable? How do we maintain them and source parts for them decades later? How can the existing turbines be improved upon? What happens to these massive structures when they reach the end of their life? Addressing these questions requires a circular approach. Many wind farms are approaching their end of life, meaning huge quantities of waste materials will need to be disposed of. In Scotland alone, 5,500 onshore turbines will be decommissioned by 2050, creating 1.4 million tonnes of waste material (Jacobs, 2021). If you were to load this onto lorries and line them bumper to bumper, the queue would extend from Cork to Belfast and back (based on a 16.5 metre long articulated truck ( RSA, 2025 ) carrying 27 tonnes ( Espace Global Freight, n.d. )). The industry urgently needs to address this waste. Each turbine has about 8,000 parts ( US DoE, n.d. ), such as gears and motors, many of which will fail or will need to be replaced regularly over its lifespan. These parts currently end up in a landfill or are melted down to be recycled. Producing the materials for replacement parts accounts for 83% of their emissions (Arias Losada, 2021) . The wind industry creates a lot of waste, but the materials used to replace parts are also a major source of emissions. The Circular Solution Renewable Parts is a Scottish company tackling waste in the wind industry. Renewable Parts began exploring the reuse of parts in the Wind Industry in 2012, but it took until 2018 for the idea to gain real traction. This illustrates both the inertia in shifting industry mindsets and the persistence required for circular business models to succeed. Their work points towards a growing recognition that achieving net-zero goals depends on the sustainability of supply chains; and remanufacturing can be central to achieving that. Renewable Parts’ approach is simple: take end-of-life components, remanufacture them to a standard equal to or better than new, and return them to turbine owners. Wind turbines operate for decades in extreme environments, and sooner or later, some of their components are going to break. The failed parts, along with parts from decommissioned turbines, are taken to Renewable Parts’ facility in Lochgilphead. Here they are stripped into components, and everything down to the bolts and washers is cleaned and inspected. The bearings, seals, and grease are always replaced, and individual worn-out components are refurbished or swapped out. Once reassembled, the parts perform like new and even have the same warranty. This reuse of material enables lower cost parts and diverts a huge amount of materials going to waste. Despite common misconceptions that remanufactured parts might be somehow inferior to new parts, industries such as aerospace have long relied on them, proving their safety and reliability. In fact, remanufacturing often outperforms original manufacturing, as data from past failures enables engineers to design out weaknesses and produce improved parts. Far more rigorous than repair, remanufacturing delivers high-integrity products that often surpass the originals, positioning it as a cornerstone of a high-quality and sustainable industrial future. Renewable Parts tracks exactly how components fail: by age, manufacturer, and even the specific conditions of the turbine e.g., wind alignment. By pinpointing the root causes, they can redesign vulnerable parts. The result? Remanufactured components that are stronger and often outlast the originals. In one example, an improved Siemens 1.3 yaw drive showed a 10% reduction in failures compared to the original design (Cross, 2024). Renewable Parts demonstrates how remanufacturing with a circular business model can improve quality while reducing time, cost, and carbon. And it's working; turnover is growing by 37% year on year (Zero Waste Scotland, 2024) , with remanufacturing already accounting for 38% of revenue. The company aims to raise this to two-thirds within five years, and in the process create more skilled jobs in rural Scotland. The Differences Between Repair, Refurbishment & Remanufacture Repair is the most basic intervention, focused on fixing a specific fault to get a product back into working order. This process typically involves minimal disassembly and only addresses the failed part without assessing the overall condition of the item. The goal is to restore function, not to improve the product's lifespan or appearance. Refurbishment goes a step further than repair. It involves restoring a used product to a functional, but not necessarily "like-new," condition. The focus is on fixing obvious faults and improving its cosmetic appearance. Parts are repaired or replaced as needed, but the product is not completely disassembled. A refurbished item will often have a limited warranty and may not meet original performance specifications. Remanufacture is the most rigorous and comprehensive process. It involves disassembling the product completely, inspecting all individual components, and replacing or restoring worn-out or obsolete parts with a combination of reused, repaired, and new parts. The goal is to return the product to a like-new or better-than-new condition in terms of performance, appearance, and quality. A remanufactured product typically comes with a new warranty that is equivalent to or better than the original product's warranty. Climate Impact The remanufactured parts offer significant carbon savings. Customers receive carbon certificates, allowing them to measure their reductions and compare the value directly against buying offsets. Between 2018 and 2024, Renewable Parts’ remanufacturing has saved 579 tonnes of CO 2 equivalent (Zero Waste Scotland, 2024) . That’s equivalent to the electricity of roughly 540 homes in Ireland for a year. In that same period, they have diverted 198 tonnes of material from landfill (Zero Waste Scotland, 2024) , or about seven articulated lorries full. The potential impact across the wind industry is vast. Research commissioned by the Coalition for Wind Industry Circularity, of which Renewables Parts is a member, found that if just ten out of the thousands of parts in a turbine used a circular supply chain, it could save 800,000 tonnes of parts from being scrapped in 10 European countries by 2035. This market would be worth 9.6 billion GBP (11.1 billion EUR) and create 20,000 jobs (BVG Associates Limited, 2023) . Circular economy solutions aren’t just good for the environment - they also make clear economic sense. This presents a huge untapped business opportunity; Stephen Fitzpatrick of the National Manufacturing Institute Scotland said, “Renewable Parts Limited are the only company in Scotland, and arguably the UK, that are picking this up. But they can only do so much. We need many, many more of those companies or for Renewable Parts to grow significantly.” Replicability Vestas , one of the world's largest turbine manufacturers, operates a refurbishment facility of 120 people in Lübeck, Germany. Failed generators are refurbished, cutting their CO 2 emissions by more than half compared to producing a new one. This supports their goal of reducing supply chain emissions in their service business by 45% by 2030 (Arias Losada, 2021) . Siemens Gamesa operates 11 repair centres globally, which offer reduced costs and lead-times, with improved reliability and availability of parts (Siemens Gamesa, n.d.) . They have also launched the "RecyclableBlade," the world's first fully recyclable wind turbine blade, which uses a new resin type that allows for the separation of blade materials at the end of life (Siemens Gamesa, n.d.) . BladeBridge , an Irish company and CIRCULÉIRE member, repurposes old wind turbine blades into new products such as bridges and outdoor furniture. The blade is used in place of virgin materials such as steel and concrete, resulting in a 20-50% lower environmental impact. The products also require less maintenance, saving money over their lifespan. Their products have been used on the Achill Sound and Midleton to Youghal greenways, as well as communities across the country. Read our BladeBridge case study here. GE Renewable Energy partnered with Veolia North America (VNA) to process blades from its U.S.-based onshore turbines, shredding them for use as a raw material for cement manufacturing. These examples show how circular solutions are fostering an entire ecosystem of companies, each specialising in different aspects of wind turbines. ALL CASE STUDIES

121bac0e-7611-436c-9e08-8ecda0e35c88 CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: ETH ZURICH WEBSITE: ETHZ.CH SECTOR : BUILT ENVIRONMENT PUBLISHED: 18 SEPTEMBER 2025 TAGS: SUSTAINABLECONSTRUCTION, GREENCONCRETE, CIVILENGINEERING, MATERIALINNOVATION, CEMENT, CONSTRUCTIONTECH, RECYCLEDAGGREGATES The Challenge Concrete manufacturing is a major contributor to global greenhouse gas emissions, accounting for approximately 6–8% of worldwide CO2 emissions. This stems largely from the energy-intensive process of heating limestone at very high temperatures during cement production, a key ingredient in concrete ( IEA, 2023 ). With ongoing urbanisation and industrial growth, demand for concrete is expected to rise, intensifying its environmental impact. Energy consumed during the day-to-day functioning and maintenance of buildings represents about 30% of global energy consumption. This increases to 34% when including the energy used to produce of cement, steel and aluminium in their construction ( IEA, 2023 ). The construction sector also requires huge amounts of resources and accounts for about 50% of all extracted material ( European Commission, 2018 ). These figures underscore the critical need for circular approaches that reduce resource use and emissions in construction. The Circular Opportunity Zurich’s Ultra Green Concrete (UGC) project, led by ETH Zurich, offers an innovative model for sustainable concrete production. Cement production typically involves using around 95% clinker mixed with a small proportion of gypsum. The clinker is created by heating limestone and clay in kilns at roughly 1,450 °C, a process that inherently generates carbon dioxide through the breakdown of limestone ( Ethz.ch , 2023 ). The UGC project reduces reliance on clinker - the most carbon-intensive components in cement - by substituting it with alternative minerals such as calcined clay and limestone. This lowers the overall cement content and cuts CO 2 emissions in the concrete manufacturing process ( Ethz.ch , 2023 ). In parallel, the ETH Zurich ‘Airlements’ project utilises recyclable mineral foam to create 3D-printed formwork components, which further reduces the volume of concrete needed on site. The foam is made from recycled industrial waste formed together with foam and finished with a cement-free protective plaster which can be assembled into a two-meter-tall system for non-structural walls ( Designboom, 2023 ). This combination of material innovation and smart construction techniques improves both resource efficiency and sustainability in building processes. ETH Zurich’s approach also focuses on recycling demolition waste as input for fresh concrete production. By reusing up to 98% of recycled concrete in new builds, exemplified by and extension to Zurich’s main art gallery Kunsthaus Zurich, this approach avoids landfill disposal and conserves virgin raw materials ( Bloomberg, 2021 ). Climate and Resource Impact These circular methods have yielded measurable emissions reductions. The UGC project has achieved nearly a 40% reduction in CO 2 emissions compared to traditional concrete mixes. Depending on the application, the project’s concrete can emit as little as 80–100 kg of CO 2 per cubic metre, compared with approximately 300 kg/m³ for conventional mixtures ( ETH Zurich, 2023 ). Additionally, by employing recyclable mineral foam formwork, UGC reduces concrete usage by up to 70%, further amplifying the environmental benefits ( 3D Printing Industry, 2025 ). The project has also saved an estimated 17,000 m³ of virgin materials and significantly reduced landfill requirements, aligning with circular economy principles of waste minimisation and resource conservation. Replicability and Industry Innovation Zurich’s success has inspired a growing movement among companies and cities worldwide to adopt circular concrete technologies. The UGC project aims to make high-performance, low-carbon concrete more accessible to the broader construction sector ( ETH Zurich, 2023 ). The UGC project serves as a practical model for sustainable manufacturing of construction materials. Ireland’s own manufacturing and construction industries can draw valuable lessons to support circularity, reduce emissions, and meet net-zero commitments through innovation in recycled concrete technologies and material efficiency. Examples of emerging sustainable concrete innovations include: CarbonCure Technologies injects recycled CO 2 into fresh concrete, permanently mineralising the gas and lowering the carbon footprint while maintaining performance. Biomason uses microorganisms to ‘grow’ biocement, dramatically cutting emissions from cement production and producing certified biocement products in commercial-scale factories. Neustark captures carbon dioxide from industrial biogas plants, storing it safely within recycled concrete aggregates to create a long-lasting carbon sink and producing certified carbon credits. These innovations demonstrate significant progress in transforming concrete from a major CO 2 emitter into a material aligned with circular economy and climate goals. ALL CASE STUDIES

Within that mix of waste, we discard approximately 22,000 disposable takeaway cups every hour. That’s 528,000 a day or an estimated 200 million annually, translating to 3,700 tonnes of single-use cup waste generated every year ( Recycling List Ireland, 2018 ). Most of these cups are made from paper lined with polyethylene (PE) to make them waterproof ( Repak, 2018 ). PE is the world’s most commonly produced plastic ( Science Direct, n.d ). While it is technically possible to recycle the cups, most paper mills do not have the capability to do so ( Repak, 2018 ). As a result, most cups end up in landfill or are sent to incineration ( Smyth, 2024 ). Disposable cups are also among the top 5 items found as litter along our coastline (Clean Coasts, 2024) where they break down into harmful microplastics that damage marine life, coastal ecosystems and ultimately end up in the human food chain ( Department of Health, Western Australia 2021 ). Microplastics have been found in virtually every part of the human body including the brain, lungs, placenta, bone marrow, as well as in blood, urine and breast milk ( Yale Environment 360, 2024 ). The Circular Opportunity Shareclub is a multi-award winning Irish company, and CIRCULÉIRE member, offering smart reusable solutions to help their clients reduce their environmental impacts. Founded with a mission to embed reuse into everyday operations, Shareclub helps offices, canteens, events and cafes replace disposable cups and bowls with reusable alternatives, supporting organisations to meet their sustainability goals. Shareclub provides businesses with reusable hot drink cups, reusable cold drink pint cups and reusable bowls for regular use in their workplace canteens or cafés, as well as for corporate events, conferences, and festivals. Shareclub offers their clients a borrowing system to suits their needs, such as RFID tags which are ideal for canteens or cafés, or a borrow & return app which is more suited to campuses and workplaces. They also offer branded options for customers who wish to buy their cups outright. Shareclub’s technology tracks borrowed items, providing clients with customised impact dashboards and measurable data—such as CO₂ savings and waste reduction metrics—for their sustainability reporting. Shareclub helps businesses integrate sustainable practices into their day-to-day operations and backs it up with real reportable data. By offering a digital borrowing model for reusable cups at events, workplaces, cafés, and take-away services, Shareclub ensures high return rates and significant waste reduction. Their services include impact dashboards and reporting tools that help businesses manage reusable stock and access sustainability insights. Shareclub’s digital system keeps track of usage and return rates, providing precise data on waste reduction and environmental footprint—all crucial to Corporate Sustainability Reporting Directive (CSRD) reporting ( Shareclub, 2025 ). How Shareclub's RFID Technology System Works (Shareclub, 2025) Climate Impact Shareclub has already made a notable impact by saving over 15,000 disposable cups and preventing more than 5,700 kg of CO₂e emissions ( Shareclub, 2025 ). Their digital-enabled reuse system produces 90% less waste and cuts procurement and waste expenses by approximately 65% ( Shareclub, 2025 ). Shareclub intends to expand their network to more than 200 partners within the next four years with a focus on waste reduction, community engagement, and behavioural change through consumer education. Their digital-enabled reuse system has reported a 98% return rate, contributing to a more circular system and a reduction in future plastic production. Client testimonials from the Dublin Coffee Festival, Guinness Enterprise Centre, and Dublin City Council demonstrate the effectiveness and positive reception Shareclub’s solution has received ( Shareclub, 2025 ). Replicability Other examples of reusable system providers include: 2GoCup is an Irish deposit-and-return scheme for reusable cups and food containers, operating across cafes and businesses in Ireland. RECUP is Germany’s largest reusable deposit system for coffee-to-go cups and takeaway bowls, with over 20,000 partner locations. Vytal is a digital, deposit-free reusable packaging system for takeaway meals and drinks, using QR codes and a mobile app to track containers. Again is a UK based company creating a network of cleaning facilities ("CleanCells") to enable the large-scale, cost-effective cleaning and redistribution of reusable packaging for brands. Loop is a global reuse platform that partners with brands to offer products in durable, returnable packaging, which is collected, professionally cleaned, and refilled. ALL CASE STUDIES

194c63c3-e43c-4b1a-8aa8-64d1987b2622 CIRCULÉIRE MEMBER CASE STUDY COMPANY: REZERO WEBSITE: REZEROMATERIAL.COM SECTOR : TEXTILES PUBLISHED: 13 AUGUST 2025 TAGS: SUSTAINABLE FASHION, WASTE TO VALUE, INNOVATION, CIRCULAR FASHION, TEXTILE RECYCLING, MATERIAL INNOVATION, CELLULOSE ACETATE, ETHICAL FASHION The Challenge The fashion industry is responsible for approximately 10% of global carbon emissions ( UNRIC, 2024 ), nearly double the combined annual emissions of France, Germany, and the United Kingdom ( EDGAR, 2024 ). Yet, despite its massive environmental footprint, 85% of textiles end up in landfills or are incinerated, with only a small fraction being recycled ( UNRIC, 2024 ). The three main drivers of the fashion industry’s pollution impacts are dyeing and finishing (36%), yarn preparation (28%) and fibre production (15%) ( Quantis, 2018 ). As a result of fibre production’s impact, man-made cellulosic fibres (MMCFs), commonly made from wood pulp, are one alternative to cotton or synthetic fibres receiving increased attention from the industry ( UNCCD, 2024 ). Cellulose is a natural polymer found in plants which is commonly sourced from cotton linters (short fibres on the cotton seed) and wood pulp ( Sid et al., 2021 ). Cellulose Acetate (CA) a plant-based plastic, is created through reacting purified cellulose with acetic anhydride, using acetic acid and most commonly sulfuric acid. CA is used to make a variety of consumer products including textiles, plastics, films, and cigarette filters. Historically, within the fashion industry CA fibre is known as ‘artificial silk’, offering a drape, feel and sheen similar to silk, but costing much less ( Yardblox, n.d .). It was extremely popular up until the 1970s when its market share declined in favour of cheaper and more durable fully-synthetic fibres like polyester ( Law, 2004 ). Though it currently represents less than one percent of the world's total fibre consumption it is still commonly used for its silk-like properties in garments such as evening wear and formal dresses, and suit and jacket linings ( Law, 2004 ). As a thermoplastic (a plastic that is pliable or moldable at certain temperatures and solidifies after cooling) CA is desirable for injection-molded products. Known for its mechanical strength, toughness, wear resistance and transparency, and ease of moldability ( Britannica, n.d.) CA is a material of choice for high-end eyewear frames ( Ray-Ban, n.d.) and for arguably one of the most important and ubiquitous fashion items, the humble button. As global fashion brands seek to tackle the environmental damage caused by the industry the demand for recycled materials is increasing. The global recycled plastics market is currently valued at USD 85.90 billion and projected to grow to USD 149.25 billion by 2032 ( Markets and Markets, 2025 ). One source for high quality recycled CA comes from an unexpected place... The Circular Opportunity Approximately 80% of all CA production is used to make cigarette filters ( C&EN, 2016 ). In 2023, more than 600 million illegal cigarettes were seized in EU operations involving the European Anti-Fraud Office (OLAF) ( TJI, 2024 ). In 2024, 112 million illegal cigarettes were seized in Ireland ( Revenue, 2025 ). Typically, seized cigarettes are destroyed by incineration but Irish company and CIRCULÉIRE member Rezero is working to make sure that valuable material doesn’t go to waste. Working with customs in Ireland and several EU countries, Rezero recycles cellulose acetate from seized cigarette butts, preventing the versatile material from being incinerated while reducing CO 2 emissions and avoiding the production of virgin CA ( Irish Times, 2024 ). The company turns their recycled CA it into premium fashion accessories, such as buttons, frames for glasses, and yarn fibres. They have also developed their own Re-Fil Fibre for wadding, insulation and acoustic panels. Their mechanical, chemical-free recycling process produces OEKO-TEX Standard 100 certified acetate and is free from harmful substances ( Rezero, n.d.). Rezero supply customers with raw material, but their mission is to become the leading EU button and fashion accessory provider, suppling sustainable buttons of any shape, size and colour. They have already begun working with fashion designers and high-profile luxury fashion brands ( Irish Times, 2024 ). As the fashion industry looks to increase the sustainability of their products, Rezero aims to capitalise on this drive by becoming a premium recycled material supplier for numerous brands. By focussing on buttons, an accessory that practically every brand needs, Rezero has a broad potential customer base. Climate Impact Rezero estimate approximately 700 billion unconsumed cigarettes are incinerated around the globe annually contributing to air pollution and greenhouse gas emissions ( Rezero, n.d. ). For every 100kg of cellulose acetate fibre manufactured by Rezero they prevent the felling of one tree and avoid up to 184 kg of CO 2 emissions from incineration ( Rezero, n.d. ). Since 2021, Rezero have saved over 160 million units of cigarettes from incineration and are aiming to recycle 1 billion filters by 2026. By repurposing low-value cigarette butts into high-value accessories for the fashion industry, Rezero helps avoid the unnecessary extraction of virgin resources while promoting sustainable and circular practices within the industry. Replicability The fashion industry has a huge sustainability problem and pressures to reduce the industry’s negative impacts on the environment are increasing. Examples of brands already engaging with their impacts: Marchon Eyewear produce and sell frames using Eastman Acetate Renew™, a sustainable material made from bio-based and recycled materials certified by the International Sustainability and Carbon Certification (ISCC). Patagonia source MMCFs from sustainably grown wood, waste streams, and fibre-production processes that use less harmful chemistries, including Eastmans cellulose acetate Naia® Renew fibre.

Every second, the equivalent of a full garbage truck of textiles is either landfilled or burned, with as much as 85% ending up in landfill rather than being reused or recycled ( UNRIC, 2024 ). Less than half of used garments are collected for reuse or recycling, and of those, only around 1% are recycled into new clothing items ( European Parliament 2025 ). The global fashion industry is responsible for around 10% of total carbon emissions - more than the emissions from both aviation and shipping combined ( World Economic Forum 2020 ). In 2023, apparel sector emissions grew by 7.5% to 944 million tonnes. The increase in emissions from the sector is largely driven by higher production fuelled by ultra-fast fashion trends and a rising dependence on virgin polyester ( Apparel Impact Institute 2025 ). Polyester, a synthetic fibre introduced in the 1940s, is derived from fossil fuels and currently accounts for 57% of global fibre production. ( Apparel Impact Institute 2025 ). Polyester's widespread use has led to serious environmental impacts, including persistent pollution from microplastic fibres, which shed during washing and accumulate in oceans and ecosystems. This reliance on a petroleum-based material underscores the urgent need for sustainable alternatives in textile manufacturing ( UNRIC, 2024 ). A Circular Solution Ambercycle is a company that transforms textile waste into high-quality regenerated polyester using advanced molecular regeneration technology ( Ambercycle, 2025 ). Their flagship product, Cycora, is a regenerated polyester yarn and fabric created from post-consumer and post-industrial textile waste ( Cycora 2025 ). Using chemistry to break down mixed fibres at the molecular level, Ambercycle extracts and purifies polyester to create new materials that match or exceed the quality and performance of virgin polyester. This innovative process allows repeated recycling without degradation in quality, significantly reducing dependency on virgin fossil-fuel-based polyester and lowering carbon emissions linked to textile production ( Ambercycle, 2025 ). By partnering with leading brands like REI, GANNI, and Arc’teryx, Ambercycle is scaling Cycora to promote circularity and sustainability in the fashion industry ( Ambercycle, 2025 ). Ambercycle’s technology starts by shredding used textiles, separating polyester from other fibres such as cotton, nylon, and spandex ( Lampoon Magazine, 2025 ). The polyester is then liquefied, purified to remove dyes and additives, and solidified into pellets that can be spun into new yarns ( Ambercycle, 2025 ). This process operates at relatively low temperatures, contributing to a reduction in CO 2 emissions. According to Ambercycle, Cycora offsets nearly half the carbon dioxide emissions of virgin polyester production ( Ambercycle, 2025 ). Independent testing by the European Center for Innovative Textiles (CETI) shows Cycora meets the standards of virgin polyester, making it a commercially viable and environmentally friendlier alternative ( Ambercycle, 2025 ). Adoption of Ambercycle’s technology across the apparel sector could reduce global emissions by over 15%, exemplifying a practical path to textile circularity and decarbonization ( Ambercycle, 2025 ). Climate Impact Production of Cycora results in half the greenhouse gas emissions compared to traditional polyester, offering a major reduction in climate impact production ( Ambercycle, 2025 ). Each tonne of fabric recycled through this process is a tonne diverted from landfill - a critical intervention to address the 92 million tonnes of textile waste created annually. Because Cycora retains the quality needed for reuse, it supports resource efficiency and extends the usable lifespan of textile materials. Brand partnerships are helping Cycora scale up and demonstrate real-world impact. For example, Inditex (the parent company of Zara) has agreed to purchase over €70 million worth of Cycora material, supporting its 2030 target to use exclusively sustainable textile inputs across all products. Large-scale commitments from market leaders like Inditex signal an industry shift towards circular solutions and highlight the practical viability of advanced textile recycling technologies. Replicability Cycora is part of a broader trend where technology companies are transforming textile waste into new, high-quality materials. Worn Again Technologies recycles textiles into raw materials by isolating and purifying cellulose and polyester, which are then spun into new fibres. Renewcell's Circulose process recycles cotton textiles into biodegradable pulp, which can be remanufactured into fibres for the fashion industry. Evrnu’s NuCycl technology turns used textiles into high-performance fibres by breaking down and regenerating textile polymers. These innovations are making textile-to-textile recycling increasingly replicable and scalable, encouraging adoption across the industry. ALL CASE STUDIES

c11d36ad-d879-4496-8638-4af7801836e0 CIRCULÉIRE MEMBER CASE STUDY COMPANY: WELL SPENT GRAIN WEBSITE: WELL-SPENT-GRAIN.COM SECTOR : FOOD PUBLISHED: 24 APRIL 2024 TAGS: FOOD WASTE, CIRCULAR BUSINESS MODEL The Challenge One of the earliest steps in the beer brewing process is when grain is steeped in hot water to stimulate the release of fermentable sugars for brewing. Once those sugars are released, the liquid is drained away and used in the next stage of the process. The grain that is left behind is no longer of any use to the brewer and is called Brewer’s Spent Grain (BSG). This spent grain accounts for approximately 85% of the waste created through the entire brewing process (Terefe, 2022). The brewing industry produces an estimated 39 million tonnes of spent grain per year (Bachmann, Calvete and Féris, 2022), that’s equivalent to the weight of 7.8 million African elephants. 70% of spent grain is commonly used as low-value cow feed or fertiliser, 20% is usually either disposed of in a landfill and the remaining 10% is converted into biogas (Terefe, 2022). That means approximately 7.8 million tonnes of BSG ends up in a landfill every year. Every tonne of BSG disposed of in landfill emits 513 kilogrammes of CO2 equivalent (LIFE-Brewery). BSG disposed of in landfill emits about 4 billion kilogrammes of CO2 each year. This is comparable to the same annual amount of CO2 emitted by burning 22,053 railcars worth of coal (EPA.gov). The Circular Opportunity BSG for human consumption has gained popularity in recent years, owing mostly to its health-related bioactive components. BSG is thought to be the most abundant source of phenolic chemicals, particularly hydroxycinnamic acids (HCAs) (Ikram et al., 2017). These phenolic chemicals are natural antioxidants that have been linked to the prevention of age-related chronic diseases such as cardiovascular disease, neurodegenerative diseases, type I and type II diabetes, and some cancers (Ikram et al., 2017). BSG is also regarded as a source of dietary fibre for humans, mainly viscous fibres, which aid in raising cholesterol and fat excretion and improving the digestive process (Ikram et al., 2017). The Circular Solution In Practice Well Spent Grain, a CIRCULÉIRE New Venture, is a Dublin-based Irish start-up founded by Sunkyung Choi and Patrick Nagle in March 2022. Well Spent Grain collect BSG from brewers like Rascals Brewing Company and transport it immediately to their kitchen for processing or storage. They upcycle it by creating tasty value-added snack bites. Well Spent Grain collaborated with the Prepared Consumer Foods Team in Teagasc Food Research Centre in Ashtown to develop the snacks and validate the production process. They work with ENSO to create and implement their sustainability strategy, track, and verify their performance. Their first product, Born-Again Peanut and Dark Chocolate soft snack bites, are made from upcycled BSG plus 5 additional ingredients (dates, 100% peanut peanut butter, toasted hazelnut, 70% dark chocolate and maple syrup). They provide good nutrition and a boost to adults’ energy levels. Each pack of Born-Again Bites has a natural malty, nutty, fruity flavour, with hints of dark chocolate and maple syrup. They provide 4.6g of protein per pouch and are high in fibre. They are accidentally vegan, have 100% recyclable packaging, and are hand-crafted locally. Well Spent Grain offer the consumer the opportunity to take part in the circular food economy in the easiest way possible. By picking up a pouch of Born Again Peanut and Dark Chocolate Soft Snack Bites, you are already taking part, and you get a delicious treat for your trouble. Replicability The global upcycled food market size was valued at USD 53.7 billion in 2021, and is projected to reach USD 97 billion by 2031 (J & D, 2023). Well Spent Grain has a great opportunity to cement and scale its business model alongside the thriving market while promoting the circular economy. Nutrient recovery from food waste and residues has been utilised in a variety of cases, including Niskus Biotec, a CIRCULÉIRE member, who upcycles and adds value to brewery and whiskey distillery by-products by using them to grow gourmet mushrooms (e.g., oyster, lion’s mane, and shiitake) and create myco-fermented food ingredients.
