Why certification is necessary
Sustainability is no longer just a trend – it's a key purchasing criterion. But as demand increases, so too does advertising increasingly rely on supposedly "green" terms that aren't actually regulated. Words like "vegetable-tanned" or "eco-friendly production" are often vague – and impossible to verify on the final product.
Here sets Olivenleder® a deliberate boundary.
For leather to be truly sustainable, it must be demonstrably and verifiably free of harmful substances – not just in theory, but in every single step of production. Therefore, simply using our vegetable tanning agent is not enough. Only those who... obliged to completely exclude certain substances and our transparent testing processes By completing the process, you will become a certified partner.
Brands like Vitra, BMW and Boss rely on certified certification for precisely that reason. Olivenleder® – because it shows real responsibility.
Because: Responsibility begins where greenwashing ends.
Through independent testing (e.g. TÜV Rheinland, Bremer Umweltinstitut, CTC Ars Tinctoria), clearly defined recipes and ongoing monitoring, we ensure that certified partners deliver what others only promise.

Olive leather is particularly suitable for tanneries that want to switch to truly metal-free, vegetable-tanned leather – that is, without chromium, aluminum, zeolite, or synthetic reactive tanning agents such as glutaraldehyde. It is ideal for companies that want to offer a pure, sustainable product with a high organic content.
