Identification of Technological Parameters for Vegetable Tanning of Paiche Skin Leather (Arapaima gigas) With Quebracho (Schinopsis balansae) and Mimosa (Acacia dealbata) Extract for Environmentally Sustainable Industrial Use.

Paiche farming in the Peruvian Amazon yields sufficient raw material to produce leather; however, these skins pose a pollution problem due to their limited exploitation. This research highlights the importance of employing mechanical and chemical procedures to obtain high-quality leather. Different concentrations of quebracho and mimosa extract were used to process paiche skin. The resulting leather was strong and malleable, exhibiting a flexural strength of over 30,000 flexes without deformation, higher tear strength in treatments T1 (146.23 N) and T5 (143.12 N), and higher tensile strength in T4 (16.62 N/mm2). The leather also had an ash content of less than 1%, moisture content of less than 9%, and chromium oxide content of less than 1.5%. The effluents from the process were treated and found to have acceptable pH, conductivity, and COD values.

Keywords : skin; paiche; mimosa; quebracho; tanning.
