The CIRCUT project (Circular Innovation for Recycling Complex Used Textiles) is an initiative led by RECYC’ELIT, a deeptech industrial startup. The project focuses on recycling hard-to-recycle polyester-based textiles using a unique chemical technology that operates at lower temperatures and atmospheric pressure, making it very energy-efficient. This innovative process allows for the recycling of chemically coloured and multi-fibre materials, transforming them into high-quality, low-carbon, and high added-value materials. The project aims to scale up from laboratory to industrial scale. The ultimate goal is to revolutionise the textile industry with an advanced fibre separation and recycled PET production technology.

The EU generates 12.6 million tonnes of textile waste per year, with only 22% currently collected for reuse or recycling—the rest often incinerated or landfilled. With mandating separate textile collection across the EU by 2025, the collected amount is expected to increase and we must upscale sorting and recycling capacity and efficiency to ensure sustainable recovery of the material. SORT4CIRC’s overall ambition is to improve value creation and cost efficiency through automated sorting and innovative recycling. This will generate new revenue streams for sorters and recyclers by turning non-re-wearable textiles into valuable feedstock for high-value recycling. The project will strive to unlock the current technological gaps for textile identification and value-chain traceability, while providing an overall sound business case driving circularity within the textile value chain (TVC). The use of modern digital technology in the sorting process will make it easier to achieve comprehensive information of the materials and fabrication process steps and integrate it to automated presorting and sorting for recycling processes. The different & complementary techonolgies are interlinked with each other with interoperable architecture to achieve complete traceability. Results generated are cross-checked to ensure reliability and consistency, to make decision over its optimal channel for reuse or recycling. SORT4CIRC gathers all relevant expertise to develop a systemic transformative solution enabling a traceable, circular textile industry: industrial collector and sorter, design for recycling by allowing disassembly, technology developers (machine learning, Artificial Intelligence (AI), imaging, hyperspectral, NIR, multisensors), recyclers (chemical, thermo-mechanical and mechanical), along with specialists in supply chain traking and tracing, digital passports, blockchain technology and IoT, textile business models, trade and LCC/LCA.

SOLSTICE aims at demonstrating 4 replicable systemic solutions for the territorial deployment of the circular economy (CEC) for the major industrial sector of textiles (62Mt produced/year). All steps of waste prevention and management will be included in a 5R strategy: Refuse/Reduce, Reuse, Repair, Repurpose, Recycle. The solutions developed can be replicated and cross-linked with the plastics value chain. SOLSTICE will: • Develop tools and strategies to implement the 5R approach: oFor the 4R Refuse/Reduce, Reuse, Repair, Repurpose: - Engage the different stakeholders (industrial companies, local authorities, citizens) to revise their supply chains / behaviour, and become more sober, circular and sustainable. - Scope and map current state, carry research on and analysis of relevant circular interventions per territory, - Create a methodology and blueprints of CEC interventions to be tested/piloted - Define circular guidelines and indicators oRecycle: Demonstrate innovative chemical recycling technologies, able to treat efficiently part of the major streams of polymers in textiles and plastics (PET, elastane, polyamide, polyurethane) in mild conditions. The technologies allow to recycle multicomponent and bio-based materials, complex streams, and to recycle textile into textile or coating into coating (closed-loop) or into added-value applications (open loop). They are easily adaptable and allow a local recycling. • Set-up a traceability system based on a Digital Product Passport and designed in relation to existing initiatives. The demonstration will take place in 4 EU representative and complementary territories. Knowledge-transfer and cooperation between the cities and regions involved, and with CCRI and other stakeholders and projects, will ensure an optimised development and deployment of the new circular concepts, as well as the replicability of the concept and a maximal impact. The deployment of SOLSTICE could save 4.3-10.8 Mt GHG emissions/year by 2030.
