Olive leaves used to make ecological leather
22

Olive leaves are usually seen just as a by-product of the cultivation process. wet-green® has developed a technology that uses the extract of this byproduct to tan leather. Tanning is usually a toxic process that relies on chrome. The use of chrome is not only damaging to the environment, but also to the workers that have to interact with it daily, thus increasing their risk of getting cancer. Moreover, if leather products have a high concentration of chrome, it can be harmful for consumers. wet-green® produces this ecological tanning agent similarly to how you extract tea. Some companies, like BMW, are already using this ecological leather for their cars’ interiors. The team at wet-green® is working to extend the amount of products that can be produced with sustainable leather.
