ECOFILTER transforms polypropylene filter waste into recycled monofilament yarns for high-performance filtration textiles

03/12/2025

Tèxtils.CAT member FINSA Job Group announced the successful completion of ECOFILTER, a sustainable innovation project funded by In Transit – DEVELOP (2nd Call) that applies circular economy principles to the production of technical textiles. The project focused on recovering polypropylene (PP) filter cloth waste and transforming it into monofilament yarns containing recycled content for use in new filtration fabrics.

ECOFILTER demonstrates how even highly specialized textile manufacturing can integrate recycling into production without compromising performance or quality.

During the project, FINSA Job Group completed the full cycle of collecting, recycling, and re-manufacturing functional filter clothes with its production waste. Factory-wide protocols were implemented to segregate offcuts, defective rolls, and trimmings from the calendaring, quality control, laser cutting, and shipping departments. Over 9.5 tons of clean PP waste were inventoried and reprocessed resulting in monofilament yarns containing 8% recycled PP.

FINSA Job Group aims to achieve 100% recycled content in polypropylene filter fabrics, supported by further process optimization, certification, and client validation. The company plans to scale production and strengthen its circular design strategy as part of its long-term sustainability roadmap.
