Scottish Leather Group

What Scottish Leather Group does

Scottish Leather Group is a privately-held, family-owned UK leather manufacturer operating three sub-brands — Bridge of Weir (prestige automotive leather, founded 1905), Muirhead (aviation, transport, furniture and luxury leather, founded 1840), and Lang (tanning specialist producing Wet Blue and Wet White hides) — across manufacturing facilities in Bridge of Weir, Paisley, Glasgow and China. The group operates a vertically integrated production model from raw hide sourcing (98% UK and Ireland) through tanning, finishing, cut parts, and sewn covers, and serves enterprise OEM customers including Aston Martin, Jaguar Land Rover, Polestar, Lucid Motors, Boeing, Emirates, British Airways, Singapore Airlines and 160 airlines globally, with quote-based multi-year contracts.

The company's technical core is a patented circular manufacturing process (UK Patent GB 2499329) that recovers energy from tannery waste via an on-site thermal energy plant, achieving 0kg CO2e per hide (industry-lowest LCA of 8kg CO2e/m2), 100% waste recycling, net zero Scope 1 and 2 emissions, and an 82% energy / 42% water reduction in the September 2023 Super Tannery. Proprietary sustainable chemistries include BioTAN and FreeTAN tanning technologies that eliminate heavy metals and fossil-fuel inputs, and the BioPRO protein-based foam (UK Patent GB 2628314), which combines leather with collagen-derived foam to deliver complete seating solutions for automotive and aviation customers. The group's certifications — IATF 16949, EN9100, ISO 9001/14001/45001/50001/17025, Leather Working Group Gold and SMETA — underpin OEM qualification.

Commercially, the group generates revenue through direct enterprise sales of finished leather, cut parts, sewn covers, BioPRO foam products, and sale of bio-oil and protein co-products to food and biofuel sectors. Distribution is via brand-specific channels (Bridge of Weir for automotive, Muirhead for aviation/transport, Lang for tanning) and direct OEM relationships. Disclosed turnover exceeds £80 million with 250+ employees; a new circular materials business, SLG Technology (encircol), was established in June 2026 with Ken Munro as CEO to commercialize collagen-derived industrial applications beyond leather.
