Fashion for Good launches project promoting bio-based polyester

Fashion for Good has launched the Mass Balance Demonstrator project, which focuses on applying and expanding the mass balance attribution (MBA) chain-of-custody system for biomass-based PET in the textile industry. Fashion for Good describes this initiative as a clear step toward speeding up decarbonisation across the fashion supply chain.

The company believes that the mass balance approach can act as a practical solution during this transition. It allows brands to include renewable materials in a more affordable and scalable way.

The MBA system works by mixing renewable and fossil-based materials, while ensuring that the renewable portion is carefully tracked and assigned to final products through proper audits and certification processes.

Katrin Ley, Managing Director at Fashion for Good, explained that the industry is ready to adopt bio-based synthetic materials, but current production systems and business infrastructure are not yet fully prepared.

She added that the Mass Balance Demonstrator project aims to close this gap by creating a strong framework, gathering real-world data, and building systems that will help scale the MBA model responsibly.
