The treatment plants of the wastewater resulting from the tanning companies utilize particular processes that require the mechanical and chemical intervention, to develop the technical characteristic consistent to the use and durability for a long period.
The main interventions are:
- Leather cleaning;
- Soaking, obtained through the help of digestive products;
- Hair elimination to make visible the below part, the derma, that represents the useful product for us;
- Liming, effected with chemicals and mechanical action;
- Fleshing to eliminate the below material of the leather identified by thickness and excessive fats;
- Tanning that gives, thanks to the use of chemicals, the steadiness to a product that, without a proper treatment, tends to quickly degrade;
- Shaving that gives thickness uniformity and cleaning to the leather through a mechanical process, making it similar to a fabric (for its touch feeling and handiness) and easily usable;
- Dying, finishing that provide the aesthetic characteristic exalting the physical qualities of the leather.
