A pilot-scaled tanning process was developed to improve the environmental impact of chrome tanning in the production of high quality bovine shoe upper leathers. The best recipe developed, the physical and organoleptic properties of the leather obtained, as well as the characterization of the exhaust water effluents were detailed. Scanning electron microscopy (SEM) coupled with energy x-ray dispersion (EDX) allowed to follow the tanning process steps and better understand the cross-linking mechanisms.

Abstract
A pilot-scaled tanning process was developed to improve the environmental impact of chrome tanning in the production of high quality bovine shoe upper leathers. The best recipe developed, the physical and organoleptic properties of the leather obtained, as well as the characterization of the exhaust water effluents were detailed. Scanning electron microscopy (SEM) coupled with energy x-ray dispersion (EDX) allowed to follow the tanning process steps and better understand the cross-linking mechanisms.File in questo prodotto:
