Hides and skins, the main raw materials for leather industries, are traditionally preserved with sodium chloride (NaCl). Due to the excessive use of salt (around 40 to 50% w/w) in the curing process, total dissolved solids (TDS), and salinity are produced in large quantities by the soaking effluent during the leather processing. To address the resulting environmental threat from the tanneries and replace traditional curing, plant-based curing is a cutting-edge green technology. In this study, Tamarindus indica leaves were used as a combination of 5% powder + 10% salt and 10% paste + 10% salt to preserve goat skin for 28 days. The organoleptic characteristics, hydrothermal stability, moisture content, nitrogen content, and bacterial load were periodically monitored. After curing, the goatskin was processed into leather, the environmental impact of the wastewater was evaluated, and its physical and fibre strength was assessed. The TDS value, chloride content, biochemical oxygen demand, and chemical oxygen demand were reduced up to 65.62%, 69.38%, 31.08%, and 27.06% respectively. The prepared shoe-upper leather exhibited equivalent physical properties compared to the control. Scanning electron microscopy (SEM) image ensured the conformity of the fibre structure of the experimental leather with control. A significant correlation was seen among the skin preservation efficiency parameters, while the strongest correlation was (r = -0.996, p<0.001) between moisture content and shrinkage temperature. Therefore, T. indica leaves powder as well as paste could be an effective curing agent by reducing the use of salt in leather industries.

“…Swietenia mahogany (seed) extract was applied as a preservative on raw goat skin, and only 3% (by weight of skin) could preserve the skin up to 30 days easily (Razzaq, Chowdhury, and Uddin 2022). Fiscus hispida leaf paste (10%) with 10% common salt preserved the skin and also resulted in a substantial reduction in salinity from the soaking liquor (Hashem, Hasan, et al 2021). Persicaria hydropiper leaf paste-aided skin preservation was attempted.…”

Hides and skin preservation has been prominently undergoing salt curing technique for centuries which uses high amount of NaCl (40%) that causes huge amount of total dissolved solids (TDS) and salinity in soaking wastewater of leather processing. Recently, Phyto based preservation is getting emphasis due to being sustainable with less environmental impact. In this study, Gossypium hirstum (cotton) seed powder (5%-7.5%) with 10% salt were applied as a novel source for goatskin preservation. Curing efficiency was monitored by checking organoleptic property, physiochemical property (moisture content, shrinkage temperature, bacterial count, nitrogen content, etc.) at regular interval. Accomplishing the preservation period, preserved skins were processed into shoe upper leather. The pollution parameters were checked from soaking waste liquor to evaluate the environmental impact. SEM analysis and physical properties of the were evaluated to the quality of the produced shoe upper leather. The results revealed that newly developed preservative can preserve goatskin up to 28 days without any deterioration. Experiments reduced pollution by lowering chloride levels 65.33%-66.91%, total dissolved solids by 41.06%-35.2%, biochemical oxygen demand by 30.86%-34.28% percent, and chemical oxygen demand by 41.06%-35.2%. According to the correlation study, there were significant dependencies between the goatskin preservation efficacy parameters, with various strong correlation (r = − 0.976, p<0.001) found between shrinkage temperature and moisture content. Surface topography, physical strength of the produced leather was compatible to conventional shoe upper leather. Thus the introduced seed powder could be one of the valuable sources of eco-friendly leather preservation to reduce environmental pollution.
