Resumen

Raising paiche in the Peruvian Amazon it produces enough raw material to produce leather skins, but because of his use limited, these skins They present a pollution problem. In its research study, the importance of using both mechanical procedures as chemicals to obtain high quality leather. To bring about the process, they were used in different concentrations of quebracho and mimosa. Paiche skin leather resulting was resistant and moldable, with a bending resistance capacity that exceeded 30,000 bends without deformation, thus providing greater tear resistance T1 (146.23 N) and T5 (143.12 N), and greater traction in T4 (16.62 N/mm2), Furthermore, the leather had ashes less than 1 %, humidity less than 9%, and chromium oxide content by below 1.5%. It was also treated the effluent generated during the process getting values acceptable pH, conductivity and COD. The study I consider the legislation existing in the country to guarantee the protection and safety of workers during the management of paiche skin tanning, considering the use of chromium oxide as a high risk for the health of workers, the regulations are still insufficient and the protection and security of the workers.
