Closed-Loop Textile Recycling System for Polyester, Polyamide and Cellulosic Waste

environmentPilotedTRL 6

Imagine if your old clothes didn't end up in a landfill but were melted down and spun back into high-quality new outfits. This effort creates a roadmap for turning household fabric waste into raw materials for clothing brands. It's like creating a giant urban mine for fabric, making sure the materials stay in use instead of being burned.

The business problem

What needed solving

Less than 1% of clothing is recycled into new clothes, leading to a 100 billion euro annual market loss and massive landfill waste.

The solution

What was built

A full-scale demonstration of recycling polyester, polyamide 6, and cellulosic waste into new garments, including a technical blueprint and circular design guidelines.

Who can put this to work

Apparel & Fashion
enterprise
Target: Sportswear and clothing brands

If you are a clothing brand dealing with high waste and sustainability targets — this project developed circular design guidelines and prototypes that allow you to create new garments from recycled polyester and polyamide 6.

Waste Management
any
Target: Municipal waste collection services

If you are a waste manager dealing with the January 2025 EU Directive requiring separate textile collection — this project developed a blueprint for sorting and pre-processing that improves the purity of feedstock for recyclers.

Textile Manufacturing
mid-size
Target: Yarn spinners and fabric mills

If you are a textile mill dealing with volatile raw material prices — this project developed a process to turn household waste into usable yarn, potentially tapping into a 30 billion euros/year market.

Frequently asked

Quick answers

What is the potential market value of this recycling process?

Based on available project data, reaching a 30% recycling rate could valorize a 30 billion euros/year market.

Can this be implemented at an industrial scale today?

Based on available project data, sorting efficiency is currently low and manual sorting remains costly, suggesting that automation is needed to reach full industrial scale.

Who owns the intellectual property or licensing for the recycling technologies?

The project data does not specify licensing terms, but it was coordinated by ADIDAS AG with 15 industry partners involved in the value chain.

How does this help with upcoming EU laws?

It prepares businesses for EU Directive 2018/851, which requires all member states to establish separate household textile waste collection by January 2025.

How is the data integrated across the supply chain?

The project developed an interoperable data model to align captured data with real-world material flows across the recycling value chain.

Consortium

Who built it

The consortium is heavily industry-driven, with 15 industrial partners (88% of the group) and only 2 universities. Led by a global giant (ADIDAS AG) and including 4 SMEs across 8 European countries, the group is structured for commercial application rather than academic research, focusing on the entire value chain from waste collection to final product.
