BioPRO: Advancing Sustainable Automotive Seating
Innovation in automotive interiors is constantly evolving, and materials are at the heart of that change.
We’re proud to introduce BioPRO, our next-generation, protein-based moulded seat foam developed specifically for the premium automotive sector.
Containing 20% protein content recovered from our own manufacturing process, BioPRO reduces fossil-derived inputs while eliminating the need for additives such as melamine, bromine and PFAS. Lightweight, durable and naturally fire-resistant, it delivers the performance expected of luxury interiors, without compromise.
Each component is moulded precisely to specification, improving fit, reducing waste and enabling tailored comfort for design and engineering teams. At the end of its life in a car, BioPRO is fully recoverable, enabling a new-found level of circularity.
Originally launched for the aviation sector by our sister company Muirhead, BioPRO’s introduction to automotive marks another step forward in Scottish Leather Group’s commitment to responsible material innovation.
For our partners, it offers something powerful: a more sustainable seat solution that also sets new standards for comfort, quality and circularity.
CCO James Muirhead said:
“For decades, we have been proud to support our automotive partners as they work to reduce the environmental impact of their interiors. BioPRO is the next step in that journey. It reflects years of commitment from our innovation team and a shared ambition with our customers to move away from fossil‑derived content while maintaining the quality and comfort they expect.
Developing more responsible material solutions is a key priority across the Group, as demonstrated by the new tanning technologies introduced in 2024. With BioPRO being fully recoverable at end of life, it enables new pathways for seat components without compromising durability. It represents a meaningful advancement in supporting more sustainable automotive interiors.”
