Scalable Production of Sustainable Lyocell Filament Yarns for Circular Textiles

manufacturingPilotedTRL 5

Imagine making high-quality fabric from orange peels instead of oil. This project creates a way to turn plant waste into smooth, strong threads that feel like synthetic materials but are fully recyclable. It's like upgrading a small-scale lab experiment into a real factory process for eco-friendly clothes.

The business problem

What needed solving

The textile industry is fragmented, making it slow to adopt sustainable alternatives to fossil-based filaments like PET and Polyamide. Lyocell filaments exist but lack the industrial scale and value chain integration needed for mass market adoption.

The solution

What was built

A production process for Lyocell filament yarns using 2G feedstock (such as orange peel pulp) and automated spinning solutions to improve stability.

Business applications

Who can put this to work

Apparel
enterprise
Target: Sportswear brand

If you are a sportswear brand dealing with high plastic content in your gear — this project developed Lyocell filament yarns that provide a smooth touch and high performance while reducing reliance on fossil-based materials.

Automotive
mid-size
Target: Car interior manufacturer

If you are a car interior manufacturer dealing with non-recyclable PET fabrics — this project developed sustainable filament yarns for automotive interiors that are designed for a circular economy.

Technical Textiles
any
Target: Industrial fabric producer

If you are an industrial fabric producer dealing with the need for sustainable technical reinforcements — this project developed 2G feedstock-based filaments that meet industrial performance criteria.

Frequently asked

Quick answers

What is the current industrial scale of this technology?

The project starts at a pilot stage (TRL5) and aims to move toward industrial scaling to enable market uptake by 2030.

How does the cost compare to traditional synthetic fibers?

Based on available project data, specific cost figures are not provided, but the project focuses on improving commercial viability and business planning to ensure market readiness.

What is the IP or licensing status for the Lyocell filament process?

Based on available project data, the process was developed by a European-based global innovator, and the project focuses on validating production processes for wider market uptake.

When will this be ready for commercial use?

The project aims for market readiness within 1–2 years after the project ends, targeting a date by 2030.

How is the technology integrated into existing textile chains?

The project forms an umbrella across the value chain, involving 15 industry partners to jointly define and push production boundaries from pulp to fabric.

Consortium

Who built it

The consortium is heavily industry-driven, with 15 out of 19 partners coming from the industrial sector (79% industry ratio), including 5 SMEs. This structure indicates a strong focus on commercialization rather than basic research, with partners spanning 8 countries to ensure a cross-border European value chain for textile production.
