In the present work, the behaviour of the four commercial products with non-swelling capacity in the pickling/tanning processes of sheepskins is studied. The successful application of these products to thinner skins would allow us to reduce salinity and, hence, the conductivity of waste waters.
The results obtained by using these products are compared with those achieved by applying a conventional pickling/tanning process.
