PRODUCT QUALITY AND SUSTAINABILITY
Most of Kara Group hides use METAL FREE tanning whose concentration of the individual tanning metals linked to it (chrome, aluminium, zirconium, titanium and iron) must be less than 0.1% and i.e. less than 1000 mg/ Kg or ppm (UNI EN 15987:2012 2012).
Metal-free tanning allows the creation of products with a very low environmental impact and therefore highly ecological and with high biodegradability characteristics.
