Leather Characteristics:
Extreme fine grain, less veins and higher productivity

6. ICIS innovation awards 2011,
rewarded with special mention
within the ICIS environmental
benefit award
Water: Less water is needed during
tanning and can be used
directly into the liming stage
Energy: Less energy is needed due to
shorter process, as well as the
reduction of chemicals from
normally 6 to only one
Salt: No additional salt is needed
during the process, reducing
the salt in the waste water by
at least 80% during tanning
