UNWASTE™ – Cushioning from Post-Consumer Textiles

UNWASTE™ is a cushioning material developed by A BLUNT STORY as an alternative to conventional plastic-based foams used in footwear uppers. Traditional cushioning layers are commonly made from virgin polyurethane (PU) foams that rely on fossil-based inputs and may contain blowing agents classified as substances of very high concern. These materials are difficult to manage at end of life and contribute to long-term waste streams.

UNWASTE™ takes a different approach by using 100% post-consumer garment waste that is unsuitable for resale or conventional recycling. Mixed and damaged textile waste is processed and transformed into a cushioning material for lifestyle footwear, diverting it from incineration or landfill.

The material is designed without virgin plastics or toxic additives and is intended to reduce reliance on fossil-based foams. By utilising existing textile waste streams, UNWASTE™ is reported to achieve an estimated 90% reduction in carbon emissions compared to conventional foam alternatives. It is also developed with recyclability in mind, enabling it to be reprocessed into the same material system.

UNWASTE™ forms part of a broader circular design strategy, aiming to convert waste into a functional cushioning solution while reducing environmental impact across the footwear lifecycle.
