Because we are committed to the development of sustainable and ecofriendly products at all stages of the tanning process, from the beamhouse to finishing.

It has developed a new line of products formed by ecofriendly retanning and fatliquoring products. The differential characteristics of these new products include biodegradability, the fact that they originate from renewable or residual raw materials, high efficacy (high fixation and hence reduced COD) and without restricted substances.
But in addition, it has also developed new sustainable processes that combine quality and respect for the environment: ECO UNHAIRING is a process where minimum quantity of sodium sulfide is used. This process generates waste waters with lower sulfide content, lower BOD and COD, and lower sludge production.
For the PICKLING stage, Cromogenia Units offers a process that allows reducing salt content and totally removes sulfuric acid. This process also provides greater chromium oxide fixation onto the hide and lower collagen degradation.
