Worn Again Technologies

Worn Again Technologies (
Private sector

    Worn Again Technologies has developed a unique polymer recycling technology which separates, decontaminates, and extracts polyester and cellulose from cotton in non-reusable textiles. The dual PET and cellulose outputs can be reintroduced into supply chains to become new fibre, textiles and products as part of a continual cycle. The technology has been developed to support the shift from linear supply chains to a circular system where raw materials become circular and start replacing the use of virgin resources.

    Implementation of the Project/Activity

    The company is currently in a pre-revenue, scale up phase, moving from lab-based developments to demonstration plant. The commercial team is London based and led by the company’s new CEO, Erik Koep. Our tech team operates from a Biocity in Nottingham, England, under the direction of our Chief Scientific Officer. We conduct industrial trials with external equipment providers and are working with our chemical engineering partner in Switzerland on the design and development of a demonstration plant which will be the focus of 2022-2023. The demo plant will provide the technical blueprint for licensing the technology to plant operators globally. 

    Worn Again plants will comply to the standards and certifications relevant to circular raw materials production, as required by the industry. With examples such as GRS and Cradle to Cradle. In addition, the ambition is to develop a holistic ‘circular licensing model', beyond the technological specifications, which provides a toolkit for social and environmental KPIs (for CO2 reductions, water savings and beyond), including metrics that capture how each plant is delivering against the UN SDGs and UNFCCC Fashion Climate Pact. 

    Arrangements for Capacity-Building and Technology Transfer

    During the commercialisation phase, the company will work with partners on an expansion plan to achieve the vision of 40 plants by 2040. In parallel, it will continue to drive forward the collaboration necessary to prepare the marketplace - especially the advanced sorting and infrastructure evolution required in the post-consumer supply chain - for textile to textile recycling to become mainstream. This includes participating in industry working groups and with conveners, including Accelerating Circularity, WRAP’s Textiles2030, Global Fashion Agenda and Textile Exchange. We also take part in pilots and industry conferences to spread knowledge about our feedstock specification and what will be needed to supply our future plants and support the rapid expansion plan to replace the use of virgin resources. We continue to build partnerships and are starting to develop regional coalitions to support individual plants that will be ready for commercialisation from 2024-2025. 

    Coordination mechanisms

    We have a Board of Directors which reports to shareholders. 


    The key principles of our industrial process are to ensure the outputs are cost competitive, comparable in quality to virgin materials, and have a significantly reduced environmental impact compared to conventional raw materials production. Success will be measured in tonnes of textiles saved from landfill and virgin materials replaced as well as environmental savings, compared to virgin production, such as CO2 reductions and green jobs generated.


    H&M Group, Sulzer Chemtech, Oerlikon, Himes, Directex, Kering, Dibella, Sympatex, ASICS Europe. Worn Again works closely with other industry organisations and cross sectorial initiatives focused on overcoming barriers to textiles circularity and advancing the reduction of the fashion industry's impacts, including the Circular Fashion Partnership (Europe/Bangladesh), Fashion for Good (The Netherlands), Accelerating Circularity (US/Europe), Circular Fashion Eco-system (UK) and Textile Exchange (US). Worn Again is also a signatory of the UN’s Fashion Industry Charter for Climate Action.
