Valorisation of Basa (Pangasianodon hypophthalmus) Skin Waste into Quality Leather Using a Non Chrome Treatment Method

Development of leather from the skin of yellowfin tuna (<em>Thunnus albacares</em>) and Asian sea bass (<em>Lates calcarifer</em>) using an environmentally friendly tanning technique

“…Moisture, protein, fat, and ash contents of the raw skin of Basa (Pangasianodon hypophthalmus) were 63.29%, 23.2%, 13.07%, and 0.94%, respectively (Sasidharan et al, 2020). Results of the present study show, leather prepared from T. albacares skin has lower moisture content (10.06 ± 1.04), lower Nitrogen content (6.03 ± 0.32), lower fat content (12.83 ± 1.60), and higher ash content (2.75 ± 0.13) than the P. hypophthalmus skin.…”

“…Processing of fish results more than 60% of waste products (e.g., damaged fish, fish trimmings and other wastage including scales, skins, heads, bones, viscera) depending on the processing level (Chalamaiah, et al, 2012). However, bulks of these materials are released into the environment resulting in environmental pollution and health-related issues due to the loading of high organic matter content (Sasidharan et al, 2020). These wastes are useful raw materials, which can be used to produce other types of value added products such as chitin, oil, peptides, collagen, gelatin, fish bone powder, and enzymes (Coppola, et al, 2021).…”

“…Moreover, there are environmental issues related to the use of some animal skins. Therefore, use of fish skin to produce leather is of great interest today as an alternative solution to protect the endangered animals and for the scarcity of conventional type raw materials (Sasidharan et al, 2020). Leather prepared from fish skins is used to prepare handbags, clothing, and shoes.…”
