The Cir4Fun Project endeavours to transform the furniture industry by championing circular economy principles across the product life cycle. Through innovative strategies, DPP and digital solutions supporting mechanisms, it aims to enhance furniture sustainability, eco-labelling, and consumer engagement while aligning with relevant regulations and initiatives. Cir4Fun's approach involves creating a comprehensive circular economy roadmap, defining content for a Furniture DPP, developing circular business models and eco-design guidelines, and establishing new assessment methodologies for maintenance, reparability, refurbishment, remanufacturing and recyclability. All this knowledge will be integrated in a holistic Furniture Assessment System (FAS) including a Sustainable Index System, d-LCA, LCC, SLCA. FAS will support the furniture eco-scoring system and DPP. Additionally, it focuses on interoperability, data sharing and data management with reliable approaches to enable simulation testing to inform supply chain strategies and extend product lifespan. Social engagement with stakeholders is emphasized to promote sustainable behaviours and circular practices, ultimately supporting new regulations and standardization in the furniture industry. The project outcomes will be implemented and validated in 3 use cases addressing different value chains across Europe and the findings will be widely circulated across the furniture ecosystem in Europe.
