The Cleantan Recipe


Cleantan® by Fraunhofer is a unique new tanning technology. It creates high-quality leather without producing chrome-contaminated wastewater. The Cleantan® process uses 70% less chemicals (no salt and 40% less chrome tanning agent) and is five times faster than conventional tanning processes. Pickling and basification take place without chemicals, only with the help of carbon dioxide. Cleantan® saves costs as well as the environment.

The frame size of the CO2 tanning unit and the workflow, e.g. filling and draining, are comparable to conventional systems, so Cleantan® is easy to implement in running tanneries.
