T-REX Project

T-REX Project

The T-REX Project brings together 13 major players from across the entire value chain to create a harmonised EU blueprint and business opportunities for closed loop sorting, and recycling of household textile waste. Transforming end-of-use textiles, from waste, into a desired feedstock, and a commodity for new business models that can be adopted at scale.

What's the challenge?

The global consumption of textiles is increasing, with global production of the two most relevant fibres, cotton and polyester, expected to grow by 40% before 2023. There is also no EU-wide plan on how to deal with the existing and anticipated textile waste: currently, 2% of post-consumer textiles are diverted to fibre-to-fibre recycling, while 87% is landfilled or incinerated. By January 2025 new EU Directive 2018/851 will require all member states to establish a separate household textile waste collection and respect increasing minimum recycling goals, but the pure legislative approach cannot alone solve the growing textile waste problem. 

Executive Summary

Across a three-year period, the T-REX Project collected and sorted household textile waste and demonstrated the full recycling process of polyester, polyamide 6, and cellulosic materials from textile waste into new garments. Simultaneously, the project aims to demonstrate sustainable and economically feasible business models for each actor along the value chain, conduct lifecycle analysis of the circular process, integrate digital tools that streamline the process of closed-loop textile recycling, and produce circular design guidelines. 

The project ultimately aims to contribute to a paradigm shift, understanding and identifying the infrastructure, technology and policy needed to encourage the growth of circular value chains. 

This project has received funding from the European Union’s Horizon Europe research and innovation programme.

T-REX Project aims to create a blueprint in Europe for creating new business opportunities based on closed-loop textile recycling using household (i.e. post-consumer) textile waste as new feedstock.

Key Challenges and Proposed Interventions

  • Limited access to quality feedstock: Despite abundant textile waste, recyclers face high costs and material shortages due to low collection rates and lack of incentives for sorters to meet recycling specs.

  • Low sorting efficiency and critical pre-processing gaps: Manual sorting remains dominant but inefficient; investment in automated technologies (like NIR and AI) and co-located mechanical/chemical pre-processing is essential to improve feedstock quality and consistency.

  • High operational costs challenge business viability: Labour and energy costs drive up OPEX; automation and access to renewable energy are key to reducing costs and scaling operations.

  • Environmental benefits depend on process efficiency: Recycling can reduce fibre-related impacts, but outcomes vary by material and technology; clean energy use and fibre compatibility with low-impact manufacturing are essential.

  • Supportive policy is critical: Introduce fair economic incentives, align End-of-Waste criteria with market needs, set realistic recycled content targets, and harmonise recyclability standards — while embedding recycling within a broader circular strategy focused on reuse, repair, and design.

    Retrofit Track

    Fashion for Good, in collaboration with its industry partner, the Apparel Impact Institute (Aii), is offering implementation support through the Retrofit Track in India. This is a limited opportunity, under which only three shortlisted facilities will receive hands-on guidance to apply the blueprint in their operations.

    Demonstrator

    Decarbonising textile processing cannot be achieved through individual technologies alone. It requires end-to-end implementation in real factories, where multiple innovations must operate together under production constraints, commercial timelines, and regional infrastructure realities. Demonstrator facilities play a critical role in bridging this gap — translating validated technologies into integrated, operating factories that generate the technical, financial, and operational evidence needed for scale.

    Blueprints

    The open-source, modular blueprint for sustainable Tier-2 textile manufacturing is a forward-looking, industry-wide tool designed to accelerate adoption of next-generation sustainability practices. It enables manufacturers to build and implement near-net-zero factories by providing clear operational pathways, alongside economic viability and social impact analysis of advanced processes and solutions. By breaking complex technical recommendations into adaptable modules, the blueprint allows manufacturers of all scales to integrate improvements in a phased, practical way, aligned with globally benchmarked best practices and emerging regulatory standards. The project aims to cover 7 geographies by 2030.
