Scotland-based leather maker Muirhead, has launched a  naturally fire-resistant, protein-based aviation biofoam.

Known as BioPRO, the patented innovation is made with hydrolysed collagen – a by-product of Muirhead’s own leather manufacturing process. With 20% bio-content, the product eliminates concerning substances such as melamine and PFAS (‘forever chemicals’) found in traditional seat foams, resulting in enhanced fire safety, durability, passenger comfort, and clear environmental benefits.

Dr Warren Bowden, Head of Innovation & Sustainability at Muirhead and Scottish Leather Group, said: “By incorporating our own bio-protein into the foam’s chemistry, we’ve eliminated the need for harmful additives while improving durability. This sets a new benchmark for next-generation seat foam technology and reflects our commitment to vertically integrated, circular manufacturing.”
