PROJECT DESCRIPTION
BACKGROUND
The project's objectives are as follows: ° reduce the environmental impact through diminished and more efficient use of chemical products in order to limit the quantity released during the production cycle ° improve working conditions Action will center upon the development and the experimentation of an industrial drum, which operates by an automized reagent dosage control system, allowing for: ° a successive work sequence eliminating the need to unload the leather for soaking ° recovery of the water from soaking baths, with the possibility of recycling ° establish the possibility to reduce operating time and a more efficient elimination of chrome tanning baths by increasing the temperature of the bath and the amount of leather to be treated by 4-5°-C/h °improving work conditions through automation of loading and unloading Experimentation of the drum demonstrated that it is possible to obtain a net reduction in amount of water and chemical products in relation to the amount of raw material used. As far as the chemical products are concerned, the innovations experimented using the new reactor regard: ° a 30% reduction in the amount of soda ° a 20% reduction of chrome in the tanning
