ABSTRACT
This study applies a new method for utilizing wasted leather scraps after chrome and vegetable tanning. It was found that alkaline hydrolysis with high pressure results in the production of fertilizer solution with N content up to 2.8% and Cr(III) amount lower than 1000 ppm. The method is actually applied.
