Bio-based circular textiles

Design for bio-based circular textiles considering existing and emerging bio-based textile materials and recycling techniques; creation and application of design guidelines for optimised use, upcycling (remanufacture), re-use and repair of bio-based textile materials; development of software tool for brands and designers. Expected outcome: guidelines for design for circularity, and design software, for garments made of (emerging) bio-based materials, with a focus on re-use and repair.



Biowaste sources

Extraction of cellulosic material from one of the following biowaste sources: straw, manure and seaweed. Expected outcome: develop two types of cellulosic materials (extraction process and material) from underutilised bio-based waste, suitable for wet spinning of textile filaments and fibres.

Development of new fibres

Melt spinning of biopolyesters (PLA blended with PHA or PBS); wet spinning of cellulosic fibres; hybrid yarn development. Melt spinning of biopolyesters (PLA blended with PHA or PBS); wet spinning of cellulosic fibres; hybrid yarn development. Expected outcome: bio-based fibres and yarns, and related processing conditions, as sustainable alternatives offering at least 80% of the performance of currently used polyester and cotton yarns of similar counts and structures.



Further processing of new textile

Further processing into textiles (weaving, knitting) and their functionalisation (coating, printing, dyeing & finishing). Expected outcome: functionalised bio-based fabrics (at least 2 knitted and 2 woven ones) for garment making with minimal microfibres release able to replace polyester & cotton fabrics. Bio-based functionalisation for water repellency and moisture & thermal management. Processes for bio-based coating, printing and dyeing, using conventional textile equipment.

Digital tools for monitoring of process

Demo: digital tools for coordinating local short run production and tracking of raw materials to ensure ‘sustainable origin’ and ‘circular use’. Expected outcome: manufacturing of basic prototype garments using networked manufacturing (from fibre to garment) and the integrated microfactory (from fabric to garment) concepts. Validation of performance and circularity aspects.



Impact methods and tools

Environmental and social impact assessment methods and tools, supporting life-cycle analysis and eco-labelling across value chains and aggregating data for policy implications. Expected outcome: Comprehensive sustainability and social assessment of the prototypes, tailored for professional and laymen public. Prevention of microfibre release by providing strategies for countermeasures along the whole manufacturing textile value chain.

EU-wide stakeholder

Establish EU-wide stakeholder engagement and capacity building for bio-based circular textiles across the industry. Expected outcome: EU-wide community of like-minded actors all along the value chain, to promote bio-based materials by building on the shared vision and cooperation framework of the TCBL network of innovation labs, designers and manufacturers. Improved Circularity.ID label/tag for tracking of materials and processes along the value chain and for easy sorting for (larger scale) recycling options.



Dissemination & exploitation

Dissemination & exploitation – Innovative business models, aggregating niche markets, offering garments as a service, intermediating material flows, etc., enabling business viability for the circular economy. Expected outcome: providing tangible input (market study, business models, demo materials, material data sheets, processing guidelines, etc.) for take up by the industry; trainings (in collaboration with VET providers), provide standardisation and policy input
