At Bridge of Weir, we are committed to delivering environmentally sustainable leather solutions without greenwashing.

Intensively developed over a number of years, BioTAN® and FreeTAN® offer an increased bio-content and remove fossil fuel, oil-derived components, and heavy metals from the processes and products.

BioTAN® is a hybrid technology that incrementally increases the bio-content within the chrome-free leather process, resulting in finished products without compromising on performance. By progressively replacing traditional components with bio-based materials, BioTAN® achieves a balance between environmental sustainability, performance and quality.

FreeTAN® offers a full replacement of existing tanning chemistry with compostable technology. Completely chrome-free, heavy metal-free, and aldehyde-free with biodegradability properties, FreeTAN® sets new environmental sustainability standards while delivering finished leather products with exceptional performance.
