ABSTRACT
The aim of this work was to look for an efficient and environmentally safe solution for the leather tanning industry through a problem of non-linear programming. The results were promising and showed a significant potential of wastewater reduction. Reuse of internal streams reduced around 70 percent wastewater. The solutions obtained could reduce significantly the amount of chemicals and consequently the amount of waste to be treated.
