The main by-product in the manufacturing of viscose is glauber salt, which can be used for the making of detergents. Other by-products such as fiber residues are refined and further processed to cosmetic cleaning pads and other polishing pads.

All other process emissions (into the air and into the water) are strictly regulated by national and European laws. It goes without saying, that all aerous emissions and waste water of ENKA are treated according to the relevant laws, and ENKA’s waste water is especially treated in a biological waste water treatment plant. Emissions into the ground are totally forbidden in Europe.
