Ahorro de aguas y materia prima en los procesos de pelambre y curtido del cuero mediante precipitación y recirculación de aguas. Revista DYNA · Jan 1, 2010

This study focused on reducing water and raw material use in leather tanning processes through chromium precipitation and water recirculation during the liming and tanning stages. By treating and reusing wastewater, the process achieved over 99% chromium removal and allowed direct recirculation of liming water up to three times without affecting leather quality.

Results showed water savings of up to 64% and raw material savings of 32% in the liming stage, and 17% savings in tanning. These practical and low-cost strategies demonstrate that the leather industry can significantly reduce its environmental impact while maintaining production efficiency, highlighting the potential of simple circular solutions in traditional manufacturing sectors.
