Ahrend furniture is designed to optimise employee’s experiences with the focus on stimulating health, wellbeing, and productivity in workspaces. The Challenge As educational levels improve and the service industry expands, so will the number of individuals with formal office positions, causing a growth in office space and furnishings ( Ellen McArthur Foundation, 2021 ). Although this benefits people’s livelihoods, it has a negative influence on the environment by increasing waste. In Europe, 10.78 million tonnes of furniture waste is discarded yearly ( Forrest et al., 2017 ), which is the approximate weight of 53,900 adult blue whales. Only 10% of that furniture is recycled, while 80% - 90% is incinerated or ends up in landfills ( Forrest et al., 2017 ). Producing the average piece of furniture emits 47 kilogrammes of CO2, which is comparable to burning nearly 20 litres of petrol ( Lai, 2023 ). The Circular Solution In the 1990s, Ahrend was involved in the development of Ecodesign, the European guideline for environmentally-friendly product design. Since then their new products are designed to be modular, sustainable, repairable and parts are designed to be easily separated for reuse or recycling. In 1994, Ahrend designed the A220 office chair which was was one of the first Ecodesign products in the world. In 2011, they became the first and only Cradle to Cradle company in the furniture industry. Cradle to Cradle is a global certification system which scores brands for their commitment to the circular economy, the reduction of waste and hazardous chemicals, more efficient uses of resources and the reuse of materials, energy efficiency, and social responsibility ( Good On You, 2023 ). Ahrend now offers their customers a “Furniture as a Service” (FaaS) option, in which they rent their office furniture for a fee, based on the length of time that they require it. Ahrend provides maintenance, storage, and insurance for all products in use during this time. When a customer no longer requires the furniture, it is returned to Ahrend and refurbished, thereby prolonging its life and decreasing virgin material use. This business model has several advantages. As Ahrend maintains ownership of their product throughout its lifetime they are incentivised to design it for durability and to be easily repairable and remanufactuarable in the future. This in turn reduces waste, CO2 emissions and the need for additional virgin resources. The FaaS business model also ensures the end-of-life of a product is considered right from the early design stages and influences the materials chosen for production, assessing them on their recyclability and lack of toxicity. Climate Impact Ahrend lowers CO2 emissions by up to 40% each year by redeploying materials and products. The FaaS model also cuts costs. Consider a new working environment with a total investment value of €45,000 over a time frame of 60 months. If the FaaS model is opted for versus buying, a €6000 savings could be achieved on the end cost ( Ahrend, 2023 ). FaaS makes more financial sense once you consider the savings from maintaining a work environment such as logistics, interest, storage, and maintenance expenses. Furthermore, Ahrend’s manufacturing process is CO2 neutral, using 100% renewable energy and closed water and energy circuits with heat pumps to reduce its CO2 footprint. Replicability Under the Product as a Service (PaaS) business model companies offer their physical product as a service. This model incentivises companies to consider longevity, maintenance, reuse, re-manufacture, and recycling in their product design. All this is done in close collaboration with customers, who become “users” of a service instead of “consumers” of a product. The PaaS model has already been applied to cars, bikes, smartphones, clothes, printers, solar panels, tires, etc. For example... Amsterdam’s Schipol Airport, pays Philips and Cofely for ‘light as a service ’. They save on maintenance costs and extend the service life of the light fittings by 75%. It further limits raw material consumption, because every component can be recycled or re-used at the end of its service life ( EU, 2023 ). Homie , in the Netherlands, offers a pay-per-use washing machine subscription where customers pay less for wasing at lower temperatures ( CEF, 2023 ). ALL CASE STUDIES

a4740068-36be-456d-ade7-4fe19cface0a CIRCULÉIRE MEMBER CASE STUDY COMPANY: ARCOLOGY WEBSITE: ARCOLOGYSYSTEM.COM SECTOR : BUILT ENVIRONMENT PUBLISHED: 24 APRIL 2024 TAGS: CIRCULAR IT, CIRCULAR BUSINESS MODEL About Arcology System Arcology System is a smart and data-driven interior construction system that offers modularity and adaptability, unlocking circular economy value in the way that commercial fit-outs are financed, designed, procured, built, and managed for REITs (real estate investment trusts), developers, and end-users. Fit-outs are activities that prepare a commercial tenant’s interior space for occupation, such as installing flooring, ceilings, partitions, and furnishings. The Challenge Buildings account for 39% of annual global Green House Gas (GHG) emissions, with 28% originating from building operations and 11% from building materials and construction activities ( Fonseca, 2023 ). In Ireland, construction and demolition generate nine million tonnes of waste ( EPA, 2023 ), that’s about the same weight as 12,857 fully loaded Boeing 747 jumbo jets. Furthermore, most of this material is not being reused or recycled ( Nugent, 2023 ). Urgent decarbonisation is driving REITs and landlords to invest in energy and building retrofitting to reduce carbon emissions, meet regulations, and reduce financial risk, but they are struggling to find solutions to embodied carbon. Embodied carbon refers to the GHG emissions arising from materials and construction processes across the entire lifecycle of a building, as measured in carbon dioxide equivalents (CO₂e) ( Fonseca, 2023 ). The Circular Opportunity Arcology System is a circular kit-of-parts approach to interior construction that aims to solve several problems within commercial interior fit-outs on both the supply and demand side, including inflexibility, sustainability, cost-effectiveness, and labour shortages. It uses lightweight, post-consumer recycled aluminium profiles to create a “smart grid” that can integrate various interior components (doors, walls, ceilings, lighting), allowing for easy adaptability and upgradability of the space. The system reduces waste and the use of new materials, thus contributing to a circular economy. Clients can either purchase the hardware outright or lease it (Product-as-a- Service) as an operating expense. Integrated Internet of Things (IoT) sensors collect real-time data on environmental conditions, occupancy, and asset tracking, which is gathered within a proprietary artificial intelligence (AI) assisted operations and integrated workplace management system (IWMS) platform. This data provides insights into how the space is being used and identifies generative-design layouts for improvement using already purchased modules. The material chain of custody and ‘ golden thread ’ of information are also captured across the entire lifecycle. Climate Impact Arcology System offers a data-driven and intelligent interior fit-out solution that can significantly reduce carbon emissions and enable adaptive reuse of potentially stranded assets. The system enables a circular economy value chain, from financing and design to procurement, construction, and management. The system’s design-for-disassembly approach can constantly reconfigure internal space for multiple use cases by reusing materials, rather than recycling or disposing of them, reducing the need for virgin resources and waste. 80% of buildings to meet Net-zero 2050 targets already exist, Arcology enables the adaptive reuse of these assets enabling them to become ‘smart’, and function as ‘ material banks .’ The proprietary integrated IoT- environmental and asset tracking sensors within the hardware system efficiently track materials, reducing waste and carbon emissions from sourcing to use, and enabling a circular supply chain that integrates certified products. The company’s post-consumer aluminium “Meccano™-like” connection hardware ensures that integrated and approved locally sourced materials stay in use at their highest value. They can be moved from building to building, and traded afterward, resulting in lower embodied carbon. Replicability The construction industry is one of the largest in the world economy, with approximately USD $10 trillion spent each year on construction-related goods and services ( Barbosa et al., 2017 ). As one of the most waste-producing sectors, a new approach to materials is required. In Ireland, implementation of digital product passports requiring a collection of digital data associated with a certain product is scheduled for 2026 or 2027. Arcology System provides the first step from a linear to a circular construction industry and is positioning itself as an industry leader in the circular construction sector. As sustainability becomes more important in the construction sector, circular economy practices are becoming more prevalent. Other notable businesses are: Dirtt manufactures a component-led, modular, interior construction system that is shipped from their facilities in Canada. Holcim decarbonises buildings for a net-zero future by providing low-carbon products and solutions that allow the construction industry to build better with less. ALL CASE STUDIES

Explore CIRCULÉIRE’s successful circular economy pilot projects and discover upcoming funding calls and opportunities. CIRCULAR BUSINESS SUPPORTS KNOWLEDGE EXCHANGE & POLICY ENGAGEMENTS ECOSYSTEM COLLABORATION Innovation Pilots From 2020 to 2022, CIRCULÉIRE actively supported the development of a circular economy in Ireland through a dedicated €1.5 million Innovation Pilot Project Fund. This initiative, backed by our strategic partners DCEE, EPA, and EIT Climate-KIC, funded 10 large-scale, system-wide innovation projects within the CIRCULÉIRE network. The Innovation Pilot Project Fund aimed to identify, test, and scale innovative circular solutions, with a focus on circular manufacturing systems, supply chains, and circular business models. Over the lifespan of this pilot, nine network participants were awarded funding to explore circularity within their sectors and collaborated with fellow CIRCULÉIRE participants and actors from the external circular ecosystem to bring their projects to life. To learn more about upcoming calls for proposals, application processes, and deadlines, keep an eye on CIRCULÉIRE's Latest News section (Inc link to news) and social media channels. See below for an overview of the successful circular economy demonstration projects funded by CIRCULÉIRE's Innovation Pilot Project Fund. 2022 2021 2020 Circular by Design Project Lead: Design & Crafts Council of Ireland Project Partner: National College of Art and Design The global textiles and apparel industry is the joint third highest emitter of greenhouse gases globally and operates in an almost completely linear ‘take-make-waste’ system. To address this challenge, The Design and Crafts Council Ireland (DCCI), the National College of Art and Design (NCAD) and the Creative Futures Academy (CFA) came together to design and launch ‘Circular By Design’; a first-of-a-kind training programme that supports textile and fashion designers, brands and manufacturers to make the transition to circular practices in every step of their design practice, value chain and business model. In its pilot year, Circular By Design equipped Irish businesses with the necessary knowledge and skills to create materials, products, and entire business models built on circularity principles. Participants gained a foundational understanding of the circular economy and redesign their value propositions, materials, products, services, and business models for a more sustainable future. READ CASE STUDY Circularising Single Use Plastics (C-SUP) Project Lead: Novelplast Project Partners: Irish Green Labs | Technical University of the Shannon | CÚRAM University of Galway | Connacht-Ulster Waste Regional Waste Office | Eventec | Climate 23 Irish laboratories rely heavily on large quantities of high-quality, carbon-intensive, single-use plastics. Most of this plastic, often polypropylene pipette tips, comes from Germany, the UK, or the US, and is incinerated in Ireland after just one use. A national audit carried out by University of Galway and Irish Manufacturing Research identified these pipette tips as the most common plastic lab waste. The C-SUP demonstration project tackled this challenge by turning these single-use polypropylene plastics into a valuable feedstock for Irish recyclers. Creating a circular system where lab waste becomes a resource, empowering researchers to minimize their environmental impact. Through dissemination via the Irish Green Labs network, the project aims to make purchasing recycled polypropylene labware the standard practice across thousands of Irish laboratories. READ CASE STUDY Do More with Less Project Lead: Farrell Furniture Project Partners: Atlantic Technological University Connemara | Office of Public Works This collaborative furniture take-back and remanufacturing project is an innovative shift towards green procurement by the Irish Government. Through a collaborative effort, Do More with Less, aims to develop and implement circularity within the public sector. There are two streams within this project. Stream One – Remanufacturing for Continued Use : Obsolete office furniture that was created by Farrell Furniture in the mid 2000’s is retrieved from the OPW. It is then repaired, remanufactured, and redistributed through the public sector. Stream Two – Preserving Design Heritage: The Crannac Chair, a classic chair design that is no longer produced will be studied and reverse-engineered by ATU Connemara. Allowing their future repair and reuse and keeping a classic piece of Irish Design in use for many years to come. READ 'DO MORE WITH LESS' CASE STUDY READ 'CRANNAC CHAIR' CASE STUDY Medical Devices a New Life (MEDAL) Project Lead: Offerre Project Partners: FPD Recycling | University of Limerick The healthcare sector is a significant contributor to environmental pollution, responsible for roughly 4.6% of global greenhouse gas emissions and air pollutants. An increased reliance on single-use medical devices, particularly in high-income countries, has had a large impact on this. The collection high-cost and low-volume of these devices has left traditional take-back schemes are often abandoned by producers. MEDAL offers a cost-efficient reprocessing system that extends the lifespan of medical devices without compromising on product integrity or strict reprocessing protocols. Designed with key stakeholders and regulations in mind, the system prioritises high performance, user convenience, producer engagement, and overall system integrity. The Pilot assesses automation solutions for cleaning and de-manufacturing and supports the circular design of products and packaging. The system also provides a cloud-based platform allowing device consumers to interact with the producers. READ CASE STUDY Upcycled Insulation Project Lead: Cirtex Ltd Project Partners: Tipperary County Council | Clothes Pod (https://www.clothespod.ie/ ) | Interior Creations Every year, tens of thousands of tonnes of mattresses, furniture, bedding, and industrial offcuts are sent to waste in Ireland. Currently, Ireland has no answer to upcycling this end-of life material. Cirtex is a new Irish company that is seeking to turn this soft padding material into insulation and other useful products that can be further upcycled when they reach their “end of life”. The Upcycled Insulation project, in collaboration with Tipperary County Council, Clothes POD, and Interior Creations, demonstrates how to effectively collect these materials from the public in a clean and efficient manner and convert it into high-quality insulation for housing and padding for furniture and bedding companies. This solution not only diverts massive amounts of waste from landfill, but also provides the construction, furniture, and bedding industries with a sustainable alternative for their production needs. READ CASE STUDY Circular Economy & The Power of Many Project Lead: Freefoam Building Products Project Partners: Glenveagh | Mulligan Guttering | Shabra Recycling In 2021, the EU generated an estimated 188.7 kg of packaging waste per inhabitant, with construction packaging waste playing a significant role. READ MORE The CE Power of Many initiative aims to implement a take-back scheme for unused roofline building products and packaging delivered to construction sites to prevent waste ending up in landfills. Freefoam, CE Power of Many Project Lead, are implementing this take-back scheme for the left-over products and packaging associated with their products. Furthermore, they are reviewing existing packaging to optimise its recovery and reuse. This project has also led Freefoam to partner with Shabra Plastics to develop a closed loop system from Freefoam’s production plant in Cork to Shabra’s plant in Monaghan, for all PE-LD and cardboard that flows into Freefoam. READ CASE STUDY RoboCRM | Advanced Robotics To Capture Critical Raw Materials In WEEE Recycling For A Circular Economy Project Lead: FPD Recycling Project Partners: University of Limerick | Robotics & Drives In the Electronics and Electric Equipment (EEE) sector, great strides are already being made towards circularity through the increased growth of WEEE recycling. Current methods however, struggle to recover all valuable Critical Raw Materials (CRM) from electronic devices. Modern appliances often have integrated batteries which cannot be easily accessed or removed. During WEEE recycling the process to harvest appliance batteries and their CRMs can be dangerous and inefficient for humans to carry out. RoboCRM uses non-destructive, AI powered detection methods and pattern recognition to identify and sort batteries and electronics containing batteries from the main WEEE stream. Allowing for safer and more efficient processing, and a higher recovery rate of CRMs in the recycling process, closing the loop on battery recycling in the WEEE system. READ CASE STUDY SUCCESS Sustainable Use of Carbon Contributes to Environmentally Sustainable Systems Project Lead: Dawn Meats Project Partners: BHSL Waste Solutions | University of Limerick Dawn Meats, one of Europe’s largest food processing companies, produces over 430,000 tonnes of added value meat products annually. Through their SUCCESS Pilot Project, they aim to transform Ireland's meat processing sector into a circular economy model by maximising renewable energy from by-products and residues. Partnering with BHSL, a proven technology provider in the poultry sector, and researchers from the University of Limerick, SUCCESS has identified the potential to transform animal by-products and sludge into green energy through BHSL's small-scale, energy conversion technology. SUCCESS seeks to deliver Ireland’s first circular meat processing demonstration plant extracting maximum renewable energy from processing side-streams and residues while creating a high-value end product to service the growing biofertilizer sector. READ CASE STUDY CESI Circular Economy Skills Initiative Project Lead: WEEE Ireland Project Partners: Fasttrack into IT | White Goods Association Repair to extend a product’s lifecycle is a core element of functional circular economy. For repair to be a viable option in White Goods WEEE however, there needs to be skilled workforce capable of carrying out maintenance on appliances, a service that is lacking in Ireland. The Circular Economy Skills Initiative (CESI) project addresses the skills and training bottleneck that exists by developing the first QQI-accredited appliance repair qualification course in Ireland, upskilling and training much needed repair and reuse specialists. CESI was developed with support and input from the White Goods Association ensuring that the training and modules would address industry requirements and provide the most value to participants and consumers alike. READ CASE STUDY Lithium Long Life Battery (LLLB) Project Lead: WEEE Ireland Project Partners: Wisetek | KMK Metals Long-Life Lithium Batteries (LLLBs) from electric vehicles (EVs), IT equipment, and energy storage systems offer a valuable resource for a more circular Irish economy. After reaching their first life (typically 7-10 years in EVs), these batteries still hold significant potential. The LLLB-CE project aims to unlock this potential by establishing a comprehensive LLLB management system in Ireland, allowing for the safe removal, collection, sorting, and discharging of these batteries. Developing this process and training more people in the environmental management of LLLB will create employment opportunities across the sector. Encouraging new training pathways for circular economy upskilling of current operatives in the material sorting and recycling sector in Ireland. READ CASE STUDY

3496cd27-edd3-42f2-a017-682ae4600cfe CIRCULÉIRE NON-MEMBER CASE STUDY COMPANY: BRITISH SUGAR WEBSITE: BRITISHSUGAR.CO.UK SECTOR : FOOD & BEVERAGE PUBLISHED: 03 JULY 2025 TAGS: FOOD & BEVERAGE, INDUSTRIAL SYMBIOSIS (IS), BIOECONOMY, CIRCULAR BUSINESS MODELS, NEW REVENUE STREAMS, INNOVATION, WASTE VALORISATION About British Sugar Located in Wissington, Norfolk, British Sugar is the United Kingdom’s (UK) largest sugar beet refinery. In 1912 their first factory was built in Cantley, Norfolk, and in 1936 the factories were amalgamated into the British Sugar Corporation to manage the entire domestic crop. The Challenge Industrial Symbiosis (IS) is a form of circular economy that connects businesses from various industries to increase waste valorisation, improve resource efficiency, and reduce environmental impact ( Trokanas et al., 2014 ). The gradual opening of the UK sugar market to global competition, as well as the subsequent competition with low- cost sugar produced in developing nations, contributed to a change in the global market ( Benedetti, 2017 ). The main challenge that led British Sugar to implement industrial symbiosis (IS) was the need to adapt and maintain its competitive advantage in this changing global market ( Benedetti, 2017 ). The Circular Solution in Practice British Sugar is the leading producer of sugar for the British and Irish food and beverage sectors, processing about eight million tonnes of sugar beet and producing up to 1.2 million tonnes of sugar each year. They work in partnership with over 2,300 growers. They utilise waste materials from their sugar production process, as well as certain external partnerships, to make 12 different saleable products ( EU, 2023 ). Their innovative manufacturing approach also allows them to create co-products ranging from power generation and bioethanol to animal feed and much more. For instance, the beet washing residual soil is sold under a different brand called Topsoil ( Shi et al., 2021 ). The limestone used for purification is utilised to produce a lime substance that regulates soil acidity to improve soil quality, and this business has become the primary source of agricultural lime in Britain ( Shi et al., 2021 ). They also use the highly concentrated CO2 and waste heat generated during the manufacturing process in the greenhouse to create better growing conditions for tomatoes, making them Europe’s second largest tomato supplier ( Shi et al., 2021 ). These initiatives created significant economic value by generating new revenue streams and reducing waste disposal costs ( Shi et al., 2021 ). The Wissington facility processes 3.5 million tonnes of sugar beet every year, yet less than 100 tonnes of waste is sent to the landfill ( Shi et al., 2021 ). Environmental Impact Since 2014, these processes have resulted in a 26% reduction in water usage, a 12% reduction in energy usage and a 17% reduction in CO2. The factories operate using management systems accredited to ISO 9001, ISO 14001, OHSAS 18001, ISO 50001, BRC and FEMAS. Moreover, British Sugar is playing a part in meeting the industry-focused goals of the United Nation’s 2030 Sustainable Development Goals, such as SDG9 ‘Build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation’. Focusing on continuous improvement, the company supported this goal by applying a circular solution that helped reduce its end-to-end supply chain water and CO2 footprints by 30%, and by ensuring all plastic packaging is reusable, recyclable, biodegradable and / or compostable and providing access to objective scientific advice on sugar. Replicability The British Sugar case illustrates how the groundwork of Industrial Symbiosis can create opportunities for business innovation towards sustainability, by seeking opportunities to turn waste streams and emissions from core production processes into useful and positive inputs to new product lines. Replicability enhances the goal of reusing networked resources including water, energy, and materials both within a single company or industry or across multiple businesses in traditionally separate industries. Another significant IS project is Kalundborg Symbiosis , the world’s first IS initiative that has evolved over the past 50 years. This partnership of 17 public and private companies has more than 30 different streams of excess resources flowing between them. ALL CASE STUDIES

67923338-9d95-44a5-80e3-2fb0b2337bdf CIRCULÉIRE MEMBER CASE STUDY COMPANY: ERIU WEBSITE: ERIU.EU SECTOR : TEXTILES PUBLISHED: 24 APRIL 2024 TAGS: TEXTILES, BIOECONOMY The Challenge Sheep farming is Ireland’s fourth most important animal enterprise ( Teagasc, 2023 ). Wool is a natural, biodegradable, and renewable fibre and is abundant in Ireland due to the key role of sheep farming. Wool was considered as an agricultural product in the EU until 2002, and it was a source of income for the farmers who operated in the sector. Wool’s categorisation altered through a series of EU regulations and is now currently classified as a Category 3 waste product alongside animal carcasses (DAFM, 2022 ). Wool must now be transferred to specialised processing facilities, which means high reprocessing costs and uncertain earnings for many farmers. All treatment of recovered materials needs to adhere to the guidelines of Ireland’s Environmental Protection Agency . This regulatory change, coupled with the rapid decline in the usage of natural fibres in favour of synthetic fibre production, resulted in the devaluation of wool. Farmers in Ireland are only paid 20 cents per kg ( DAFM, 2022 ), which is considerably less than the cost of shearing. This leaves farmers with no incentive to care for their wool or breed for wool quality. Currently, some sheep farmers are storing years’ worth of wool in their sheds or storage warehouses ( O’Riordan, 2022 ), which compromises the condition of the wool. The Circular Opportunity Currently, synthetic, petroleum-based polymers account for two-thirds of all textile items ( Henry, Laitala and Klepp 2019 ). Laundering synthetic clothes accounts for 35% of primary microplastics released into the environment ( De Falco et al., 2019 ). Sheep wool, on the other hand, is a natural biodegradable and renewable fibre which at the end of its life poses no threat to human health or the environment ( DAFM, 2022 ). Properties in wool also allow it to be used for purposes such as fertiliser and insulation. Wool is an excellent insulator and thermo- regulator. It responds to variations in body temperature, keeping the wearer warmer when cold and cooler when warm. It is odour and wrinkle resistant, so does not need to be washed as frequently as other fibre types, conserving water, and energy ( DAFM 2023 ). According to recent studies, regenerative wool can store carbon from the environment, thereby minimising the impacts of climate change ( Colley et al., 2020 ). The Circular Solution In Practice Ériu , a 2023 CIRCULEIRE New Venture, founded in 2021, manufactures yarn from the wool that is hand-selected, processed and designed entirely in Ireland. Ériu is the first Irish knitwear brand whose products are exclusively Irish sourced and manufactured using a ‘Farm to Yarn’ sustainable initiative. Ériu contributes to the Irish economy by sourcing wool from a trusted network of farmers around Ireland, as well as from their own farm in Wicklow. They offer farmers EUR €2.50 per kg of wool, which is more than 10 times market price. Donegal Yarns processes the wool locally, and Irish knitters in Dublin make it. Aside from local collaborations, they have established their own facility for processing wool on the farm which they intend to roll out in stages. The first stage is scouring, where they will wash the wool softly and sustainably using biodiverse methods. They already have equipment for additional stages, which will further enable an expansion of their Farm-to- Yarn networks to source and incentivise more wool collection, and create more opportunities for an expanding range of wool products. Replicability The global wool market is expected to grow from $37.06 billion in 2022 to $45.05 billion in 2027 ( The Business Research Company, 2023 ). As consumers are becoming more conscious of the environmental degradation caused by synthetic textile production there has been a rise in demand for sustainable and ethically produced textiles ( Granskog et al., 2020 ). In light of these factors, Irish wool is expected to hold significant potential for the textile sector’s sustainable transition. Ériu has an unparalleled opportunity to be at the forefront of revitalising the Irish wool market . As circularity in the textiles and fashion sector continues to be encouraged, a few companies worth mentioning include: Infinited Fiber , a Finnish company that has developed a technology that converts textile waste into a premium-quality circular textile fibre, which reduces the world’s reliance on virgin raw materials. Our Choice Fashion, based in Luxemburg, manufactures circular leather sneakers that are 100% plastic free, repairable, and recyclable. ALL CASE STUDIES

fdede40f-096c-41a9-adc3-053d6c2210ec CIRCULÉIRE MEMBER CASE STUDY COMPANY: EVOLVE WEBSITE: HTTPS://WWW.EVOLVEAUTO.IE/ SECTOR : AUTOMOTIVE PUBLISHED: 24 APRIL 2024 TAGS: REPAIR, CIRCULAR BUSINESS MODEL The Challenge Every year, an estimated 8 to 9 million tonnes of waste is generated from the disposal of End-of-Life Vehicles (ELVs) ( EPA , 2023 ). That’s equivalent to the weight of approximately 19,000 Boeing 747s. In addition, around 3.5 million vehicles disappear without a trace from EU roads each year, and are exported, or disposed of illegally ( EC , 2023 ). Since 2015, EU Member States are required to meet rates of ≥85% for reuse-and-recycling and ≥95% for reuse and recovery ( Eurostat, 2023 ). An estimated 145,628 ELVs were treated in Ireland in 2021, equating to an estimated 154,365 tonnes of waste. That’s about the same weight as 345 Boeing 747s. In 2021, Ireland achieved a reuse and recycling rate of 87.81% compared with the EU target of 85% and a reuse and recovery rate of 95.74% compared with the EU target of 95% ( EPA , 2023 ). The production of vehicles is one of the most resource- intensive industries. The automotive industry in the EU is the number one consumer of aluminium (42%), magnesium (44%), platinum group metals (63%), natural rubber (67%) and rare earth elements (30% and growing exponentially) ( EC , 2023 ). The Circular Opportunity With so many critical raw materials tied up in the production of vehicles the EU has prioritised the implementation of circular economy principles to recover those materials and to reduce the environmental impact of their disposal and the need for replacing them with virgin materials. The Circular Solution In Practice Evolve , is an independent technology- driven supply chain solution aimed at streamlining the sourcing of green auto parts for automotive businesses. Green auto parts are undamaged Original Equipment Manufacturer (OEM) parts that have been taken from a vehicle during the disassembly and recycling process which can be reused for the repair of vehicles still in service. Evolve brings together green auto parts suppliers (vehicle recyclers) and green auto parts consumers (insurers, repairers, fleets, etc.) from across Ireland and the United Kingdom in a structured, value-driven manner. To ensure that only the highest-quality green parts enter the repair cycle, all Evolve-supplied green parts are graded to the Vehicle Remarketing Association (VRA) standards. The Evolve OS technology platform, which interfaces seamlessly with clients’ workflows to deliver feasible and value- driven green parts solutions in seconds, is at the heart of the market-leading service. Evolve provides measurable net carbon emissions savings, sustainability impacts and commercial savings. Opting for green auto parts prevents the need for new parts to be manufactured, therefore creating significant energy and resource savings. It also prevents high quality used parts from ending up in landfills. Reusing vehicle parts saves approximately 35.3 gigajoules of energy and 1,887 kg of CO2 per vehicle ( Sato, 2018 ). An Garda Síochána, the Irish police force, saved the equivalent of 38,477 kg of CO2 in 2022 by acquiring 551 reclaimed vehicle parts of various makes and models. They aquired the parts for its fleet from Evolve’s partner Ted4Parts, as opposed to purchasing newly made vehicle parts. This is an average savings of 94% net carbon dioxide equivalent for An Garda Síochána ( FleetCar, 2023 ). Replicability The automotive industry accounts for more than 7% of the EU’s Gross Domestic Product (GDP) ( EC, 2023 ). The EU’s ELV Directive sets clear targets for ELVs and their components. It also prohibits the use of hazardous substances when manufacturing new vehicles (especially lead, mercury, cadmium and hexavalent chromium) except in defined exemptions when there are no adequate alternatives ( EC, 2023 ). Furthermore, consumer expectations are shifting, emphasising the importance of sustainable practises. Evolve has successfully integrated a circular business model into a thriving automobile market in order to reduce CO2 emissions and virgin resource use, while also helping Ireland reach its targets under the ELV Directive. Repair, recovery, and reuse are becoming more prevalent as nations aim to achieve their climate targets. Some examples worth mentioning include: Norsk Ombruk a Norwegian household electronic appliance remanufacturing firm that was established in 2014. Synetiq a car salvage, green auto parts supplier, vehicle repairing, and automobile software solutions provider based in the UK and founded in 1939. ALL CASE STUDIES

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.

a5b70e0a-7b0b-46bb-a0ec-f139d0268178 CIRCULÉIRE MEMBER CASE STUDY COMPANY: VOTECHNIK WEBSITE: VOTECHNIK.COM SECTOR : ELECTRONICS PUBLISHED: 24 APRIL 2024 TAGS: WEEE, CRITICAL RAW MATERIALS About Votechnik Votechnik developed a series of cutting-edge innovative robotic technologies for Liquid Crystal Display (LCD) recycling. LCD is an electronic display that is found in smartphones, tablets, televisions, and many other electronics. Votechnik’s robotic technology removes components containing hazardous substances from LCDs (e.g., mercury-containing lamps), and prepare non- hazardous materials for recycling. The Challenge The electronics industry is one of the top eight industries responsible for more than half of the world’s total carbon footprint. In 2020, the equivalent of 580 million metric tons of CO2 were emitted by Waste from Electrical and Electronic Equipment (WEEE) ( Singh and Ogunseitan, 2022 ). That is more than the emissions generated by Canada in a year (525 million metric tons) ( World Bank, 2023 ). LCDs have become the dominant technology in devices that contain displays. The rate at which people replace their devices every year results in an avalanche of discarded electronic waste. In fact, only about 38% of electronics that enter the market are subsequently collected; the remainder are discarded ( European Commission, 2020 ). LCD monitors are among the most dangerous electronic devices to discard because they contain toxic metals, including mercury, which can harm both humans and the environment. LCDs also contain rare earth metals, such as indium, which is one of the earth’s least prevalent minerals ( Royal Society of Chemistry, 2023 ). If Indium recovery is not increased, reserves may become smaller, affecting the supply chain. The Circular Opportunity Votechnik emerged from the University of Limerick, backed by the European Commission, and supported by world- class industrial players such as Siemens and KUKA . Votechnik has spent the last 10 years developing, testing, and operating their technology to the highest industry standards. They are certified compliant with the European Standard EN50625 for WEEE treatment, and their business model is specifically designed to address the EU legislative WEEE Directive. Votechnik offers a wide range of LCD recycling technologies, one of them being their Indium Recovery System, which is designed specifically to extract indium from WEEE glass panels. Their indium recovery technology is called IND2000 and is supplied as a machine to recyclers who run the process with Votechnik’s support. Votechnik’s technology is used to release and capture indium from the glass panels, achieving high extraction rates and minimizing waste. Purification techniques are used to refine the extracted indium, ensuring its quality and suitability for reuse in various applications. Furthermore, clean glass fractions are generated from the process, which can be reused in the production of the new glass products. The Indium Recovery System is designed to comply with international standards and regulations. Climate Impact By recovering this critical raw material from waste electronics, Votechnik’s Indium Recovery System ensures a stable and reliable supply chain for businesses, by reducing dependence on imported indium from China. It further contributes to environmental preservation by efficiently extracting indium from glass panels, preventing it from being lost in landfills or incinerated, and reducing dependency on indium mining. Replicability The electronic device industry is growing. The combined sales of smartphones, televisions, and computers in 2021 were USD$ 880 billion, with growth rates in 2022 expected to range between 3% - 4% ( Stewart and Crossan, 2022 ). Votechnik has effectively incorporated a circular business model into the booming electronics market, decreasing virgin resource consumption while assisting Ireland in meeting its WEEE collection targets. Recovery and reuse are becoming increasingly prevalent as nations strive to meet climate targets. KMK Metals Recycling , another CIRCULÉIRE member, provides environmentally sound management of waste metal in all forms. They collect and process 75% of Ireland’s WEEE. KMK Metals are partners with Votechnik on both their IND2000 technology plus their ALR4000 technology. The ALR4000 technology depollutes LCD displays, allowing them to be shredded before the secondary raw materials are recovered. ALL CASE STUDIES

f9c55f9d-bf24-488b-be0f-1093f40c9cfc CIRCULÉIRE MEMBER CASE STUDY COMPANY: KAFFE BUENO WEBSITE: KAFFEBUENO.COM SECTOR: FOOD & DRINK PUBLISHED: 26 MAY 2025 TAGS: FOOD WASTE, CIRCULAR BUSINESS MODEL, BIOECONOMY, COSMETICS The Challenge Many people around the world start their day with a cup of coffee. From Oct 2021 to Sep 2022, over 168.5 million 60kg bags of coffee were consumed globally, with Europe accounting for 31% of its consumption ( International Coffee Organization, 2023 ). Every year, approximately 18 million tonnes of used coffee grounds are discarded worldwide, with the majority being sent to landfill ( May, 2021 ). When coffee grounds decompose in landfills, they emit methane gas, which has a greenhouse heating effect 84 times higher than carbon dioxide (over a 20 year period). ‘If all the estimated 18 million tonnes of wet, spent grounds were left to decompose naturally, they would release over 2.3 billion cubic metres of methane annually – a global warming impact equivalent to the entire annual CO2 output of France’ ( May, 2021 ). The Circular Opportunity A circular economy is an economy that eliminates waste by design. It does this, in part, by recognising the value contained in what is normally throw away. ‘When brewing a cup of coffee, only 1% of the potential in the coffee bean is being utilised, making it one of the most undervalued resources in the world’ ( Kaffe Bueno 2023 ). Spent coffee grounds are already being used for biofuels, natural fertilisers, nutrition and personal healthcare products. The Circular Solution in Practice Kaffe Bueno is a Danish bioscience company founded in 2016. They are a Certified B Corporation who use green chemistry and biotechnology to upcycle spent coffee grounds to produce ingredients for the human-nutrition, personal-care and agro-chemical industries. Kaffe Bueno collects and dries the spent coffee grounds from selected hotels, offices, and industry partners in Copenhagen. They then extract the antioxidant-rich arabica seed oil and coffee fibres. Their circular business model has resulted in a number of marketable healthcare products, such as extracts for serums, oils, shampoos, conditioners, soaps, sunscreens, natural exfoliants and antioxidants. For the nutrition market they produce fibre rich flour for baking breads, cookies and cereals plus coffee flavouring extracts. By diverting spent coffee grounds from landfill they currently prevent up to 37 tonnes of methane emissions per year ( Kallehauge, 2023 ). Replicability The global coffee beauty products market was valued at US$593 million in 2022, and it is projected to grow to US$961.9 million by 2031 ( Transparency Market Research, 2023 ). Consumers are becoming more conscious of the ingredients in skincare products. In addition, the increasing demand for organic and natural skincare products is enhancing the market value for beauty products containing coffee. Some of the prominent players in the market such as Loreal Paris, Estee Lauder Inc., and Avon have been focusing on introducing coffee-infused beauty products to expand their offerings and serve the customers with natural ingredient-based solutions ( Grand View Research, 2019 ). Nutrient recovery from food waste and residues has been applied in many cases and for different purposes. Considering coffee waste valorisation, some examples also worth mentioning include: UpCircle is a circular skincare company that use coffee grounds to make facial scrubs amongst other upcycled ingredients from the food industry. The Coffee Cherry Co developed an extraction process for coffee cherry pulp to provide an ingredient for flours and nutrition drinks. A Note on By-Products & End of Waste A by-product is a residue left over from the production of another product. In Ireland, Regulation 27 of the Waste Directive sets out the circumstances in which a material can be considered a by-product and not a waste. It is essential you notify the EPA to determine if your material satisfies the criteria of a by-product. The EPA will confirm if it can be catogorised as a by-product or if it must be categorised as a waste. If the substance is classified as a waste then it may need to achieve End-of-Waste status via Article 28 of the Waste Directive to be kept in use as a resource. 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
