Ponda

Ponda is a biomaterials company developing novel textiles from truly regenerative fibres. Our mission is to regenerate the world's damaged wetlands through technologies that bring value to wetland-based crops. Ponda's first product, BioPuff®, is an insulation designed to keep you warm and dry, made from bulrushes that grow on regenerated wetlands. As a next-generation alternative to goose-down, BioPuff® not only is a fantastic puffy-filler, but it also contributes to removing carbon from the atmosphere, enhancing biodiversity and building climate resilience. Through working closely with farmers and landowners we're able to build confidence in their longterm farming future whilst ensuring traceability all the way from plant to puffer.
