Zeology, the new standard in tanning

The truly sustainable alternative to existing leather tanning agents. Chrome-free, heavy metal-free and aldehyde-free. Join us in our sustainable ambition.

Let’s create sustainable leather together

Nera is introducing Zeology, a whole new world for leather tanning. The zeolite-based tanning concept is truly sustainable and does not compromise on leather performance. It is just what you need to protect the Earth on the one hand, and still be able to create and use top quality leather for the manufacturing of premium leather goods, on the other.

If you share the urgency for sustainably manufactured leather, start using Zeology today! Or ask your tanneries to choose Zeology, the new standard in tanning.
