The chrome tanning is the most commonly used for the production of tanned leather, being used in more than 90% of tanned leather products worldwide. The use of this technique involves the use of trivalent chromium, a substance that under certain conditions can be oxidized to hexavalent chromium, a carcinogenic compound shown.

The main environmental impacts of tanneries from solid waste and wastewater generated. As an example we can see that in a European tanning in order to obtain a ton of leather, there are about 50 m3 of wastewater and 700 kg of solid waste, both contaminated with chromium.

Studies carried out by INESCOP have shown that the use of oxazolidine cuertiente agent in combination with other vegetable or synthetic tanning agents, is a viable alternative to traditional chrome tanning.
