The H&M Foundation is working with the Hong Kong Research Institute of Textiles and Apparel (HKRITA) on the Earth First program to build an industry that is good for the planet. One of the research projects, called reProLeather, has developed a new technology that separates hexavalent chromium from crushed leather fibers and creates a bio-based material that can be used as an alternative to PU and PVC binders, creating a new form of recyclable leather that is biodegradable and recyclable.
With many industries looking for ways to minimize waste and conserve resources, the demand for recycled materials in the fashion industry is on the rise. However, recycling certain materials can sometimes be a tricky process, and leather waste in particular can be difficult to recycle. Many recycled leathers contain harmful chemical residues, such as hexavalent chromium, which is produced during the tanning process.
reProLeather has successfully reconstituted post-consumer leather fibers into leather flakes during its research phase. HKRITA is currently looking for industry partners to optimize its product features and enhancements, paving the way for improved industry applicability in the future.
Christiane Dolva, Head of Strategy at the H&M Foundation, said, "As philanthropic change agents across the industry, we take risks to find needed solutions and are committed to finding technologies that can contribute to a planet-positive fashion future. I'm always happy to openly share our findings with others and look for industry players willing to adopt bold innovations, and ReProLeather could be one of those solutions. I hope to see it scaled up soon."
