The textile industry is at a tipping point. As the mountain of textile waste continues to grow, the European T-REX (Textile Recycling Excellence) project marks an important step towards true circularity. After three years of intensive collaboration, the consortium has reached its conclusion after a three-year research and innovation effort. Its primary outcome is a comprehensive blueprint for scaling textile-to-textile recycling across Europe. The blueprint offers practical guidance for transforming post-consumer textile waste into new fibres and products within a closed-loop system. It’s an inspiring example of how cross-chain collaboration, innovation and policy can come together to combat waste and preserve valuable resources.
The project, which began in June 2022, brought together 13 organisations from across the value chain, including academia, recyclers, brands, and technology providers, with the goal of building a harmonised European system for managing textile waste. The blueprint is informed by extensive research, including life cycle assessments (LCA), techno-economic studies, technical guidelines, and stakeholder engagement reports.
Context
Europe currently generates nearly 7 million tonnes of textile waste annually, most of which ends up incinerated, landfilled or exported. Less than 2% of this waste is recycled back into textiles. With post-consumer textile waste expected to increase further by 2030, the T-REX consortium sees textile recycling as one necessary solution, alongside reuse, repair, and better design, to address this mounting challenge.
Key findings and blueprint recommendations
The T-REX blueprint addresses four key areas critical for scaling textile-to-textile recycling: technical scalability, business viability, environmental impact, and policy support.
1. Technical scalability
- Sorting systems remain inefficient: Manual sorting dominates current practice, but it is slow, labour-intensive, and unable to handle the volume or complexity of modern textiles. The report calls for investment in automated sorting systems, particularly those using AI and Near Infrared (NIR) technologies, which can better identify blended fabrics and non-recyclables.
- Pre-processing is essential: Recycling outcomes depend heavily on the quality of pre-processed materials. The report highlights the need for mechanical pre-processing at or near sorting facilities to improve consistency, and for chemical pre-processing to be tailored to specific recycling technologies.
2. Business viability
- High feedstock cost and limited supply: Although textile waste is abundant, very little is suitable for recycling due to low collection rates and inconsistent sorting. This makes suitable feedstock both scarce and expensive.
- Operational costs remain high in Europe: Labour and energy costs are major expenses, particularly for sorting and pre-processing. Automation and access to low-impact, affordable energy are essential to improving economic feasibility.
- Recyclability must start with design: To ensure feedstock is compatible with recycling technologies, product design must avoid unnecessary blends and materials that are difficult to separate. The blueprint stresses the role of Ecodesign as a long-term solution to improve feedstock quality.
- Investment and coordination are needed: Scaling textile recycling requires joint action by industry, governments, and financial institutions. This includes targeted funding, clear regulations, and incentives to stimulate demand for recycled materials.
3. Environmental impact
- Recycling can reduce environmental burden, if done properly: The report confirms that textile recycling has the potential to cut environmental impacts associated with virgin fibre production. The extent of these benefits depends greatly on the type of material recycled and the specific recycling technology applied. Different fibres and processes vary in efficiency, yield, and environmental performance, resulting in diverse outcomes across recycling methods.
- Energy use is a key factor: Energy use is a major source of environmental impact in textile recycling and production. Improving energy efficiency and switching to low-impact energy are essential throughout the entire supply chain. Energy-intensive stages, such as recycling, dyeing and finishing, must become more efficient and make use of renewable energy where possible. Recycled fibres must also work well with sustainable manufacturing techniques to maximise environmental benefits.
- Durability still matters: While recycling is necessary, it is not a silver bullet. A garment’s total impact also depends on how long it lasts and how it is used. Designing for longevity and reusability remains a priority.
4. Policy recommendations
- Share responsibility across the value chain: All actors, from collectors to recyclers, must play a role. Economic incentives should reflect this.
- Clarify ‘end-of-waste’ rules: Legal definitions of when waste becomes a product must be aligned with practical realities to ensure recycled materials can re-enter the market. Aligning these standards will encourage the use of recycled textiles in new products and enhance EU textile waste recycling. Clear EoW rules are also key for effective EPR schemes and cross-border waste shipments.
- Set achievable targets: Recycled content requirements must be realistic and flexible enough to support innovation and the use of diverse waste streams.
- Simplify product composition: Regulation should focus on the dominant material within garments to reduce sorting complexity while allowing space for technological development.
Demonstrated outcomes
As part of the project, T-REX partners successfully produced demonstrator products using recycled polyester, polyamide 6, and cellulosic fibres. These outcomes confirm the technical feasibility of closed-loop recycling in Europe under specific conditions.
Conclusion
The T-REX project delivers a practical, evidence-based roadmap for establishing a circular system for post-consumer textile waste in Europe. However, textile-to-textile recycling is only one piece of the puzzle. The report underlines the importance of embedding recycling into a broader approach that includes product design, reuse, repair, and sustainable consumption.
