The tExtended project will achieve its overall objective of reduction of textile waste by 80% by within industrial-urbal symbiosis developing and demonstrating effective textile recovery, waste valorisation and recycling processes combined with digital tools, sensing systems and data-driven solutions to support sustainable circularity of textiles. We will develop a knowledge-based Blueprint, i.e. a master plan for a sustainable textile ecosystem. The basis of the Blueprint is a Conceptual Framework which determines the optimized utilization of textile flows, aiming for retention of value of materials in a safe and sustainable way. Based on the Blueprint, we will implement a real scale demonstrator, verifying its replicability and potential to reduce textile waste. tExtended brings together a multidisciplinary group of experts with complementary skills needed for twin transition in sustainable textile sector. Different types of organizations, research, industry, and non-profit organizations such as NGOs and municipal waste management are included. The consortium consists of actors with different roles in the textile recycling ecosystem: waste management, recycling, textile materials and textile products manufacturing. Participation of forerunner companies and actors involved in textile recycling enables us also to spread best practises for textile recovery and recycling around Europe and across the sector.
