The REFASHION project harnesses blockchain technology to establish a secure, transparent, and efficient platform for extending the life of fashion products. The online trading platform developed by the project enables users to sell their second-hand fashion items directly to others or donate them in exchange for ecosystem tokens issued by the platform administrators. These tokens can be used for discounts on future purchases or redeemed for services and products in a network of partner businesses, thus reinforcing a community-based circular economy. By doing so, the REFASHION project not only generates environmental benefits by extending the lifespan of fashion items but also promotes a new economic model that fosters sustainable consumer behavior. Furthermore, through blockchain technology, the platform ensures authenticity, traceability, and security of transactions, addressing the prevalent issues of trust and quality that challenge existing and particularly immature resale markets. Finally, the project will investigate the technical and economic challenges of developing and scaling such a platform, its potential impact on reducing fashion waste, and enhancing consumer engagement in the project ecosystem through targeted incentive mechanisms and changes in environmental behavior.
