“…Tanning is the process by which animal hides are converted into leather (1,2), offering flexibility and immunity to bacterial attack as its main characteristics (3). Currently, the conventional tanning process uses chromium as the main input, accounting for 85-90% of leather manufacturing in terms of use (4,5,6). This implementation is due to its efficiency, versatility, availability and relatively inexpensive price (7) and, consequently, makes it one of the main pollutants of the tanning industry, causing considerable deterioration of ecosystems and human health (3,8).…”

“…Having said this, the importance of sheep in the agroindustrial sector can be determined for a potential application in the tannery industries, since these are in charge of treating animal skins (23), to avoid its putrefaction. In addition, several studies indicate that sheep hides can be used for the manufacture of gloves, shoes, bags and carpets (24,25,26); however, it is evident that the use of chromium salts in this industry has significant environmental consequences (12), especially because of the large volumes of water with organic and chemical waste that are discharged into bodies of water (6).…”

Este proyecto se enfocó en la curtición de pieles ovinas (Ovis aries) a partir de los taninos obtenidos de la almendra de mango (Mangifera indica), para evaluar el potencial de este subproducto mediante el aprovechamiento del mismo. Para ello, se realizaron extracciones de taninos con soluciones acuosas de etanol-agua en concentraciones de 70%-30% y 50%-50% y se cuantificaron mediante el método Folin Ciocalteu utilizando ácido gálico como patrón. Se evaluó la capacidad de curtido en la piel ovina mediante las propiedades físicas del cuero. Se obtuvo que la mayor concentración de equivalentes de ácido gálico (GAE) fue para la extracción con etanol-agua al 50%-50% con una concentración promedio de 1,14 mg GAE/g. A partir de esto, se realizó el proceso de curtido a la piel de ovino donde se determinaron las propiedades fisicomecánicas del cuero como resistencia a la tracción con valores obtenidos de 12.7 MPa para la concentración de Etanol-Agua al 50%-50% y 11,3 MPa para la concentración de la relación 70%– 30%; porcentaje de elongación con valores de 11,7 N y 17,7 N; resistencia al desgarre con valores de 41,9 N y 58,0 N; temperatura de contracción 61°C y 60°C; distensión de 13,22 mm y 10,68 mm y rotura de 37,47 daN y 48,39 daN respectivamente. Finalmente, los cueros curtidos con taninos cumplieron con 5 de las 6 pruebas analizadas según las normas UNE-EN ISO, por lo que el extracto de taninos de la almendra de mango se muestra como potencial sustituto a las sales de cromo llegando a contribuir a una industria más amigable con el medio ambiente y a obtener cueros de calidad a partir de la piel ovina.

“…Considering the negative impact of chrome tanning, many researchers are exploring sustainable and green manufacturing processes by using alternative environmentally friendly chrome tanning processes or replacing chrome chemicals with vegetable tannins extracted from diferent parts of plants for leather industry [10,[20][21][22][23]. Application of vegetable tannin is considered to be cheap, ecofriendly, and sustainable and regarded as an alternative to chrome tanning [2,[24][25][26].…”

The purpose of this study is to replace chrome tannins with ecofriendly vegetable tannins as an alternative solution to prevent the public health and the environmental pollution. Vegetable tannin was extracted from Cassia singueana bark using an aqueous extraction method and applied on sheep pickle pelt. Optimum tannin extraction parameters were identified at powder concentration of 80 g/L, extraction temperature of 100°C, and extraction time of 120 mins. Chemical functionality of Cassia singueana extracted tannins was evaluated via FT-IR spectroscopy. Hence, the FT-IR spectrum confirmed the presence of wide band of phenolic hydroxyl (OH−) and carboxyl (C-O) groups connected with the aromatic ring. Moreover, physicochemical performance of the Cassia singueana extract tanned leather sample was scientifically examined and showed comparable results to conventional Mimosa tanned leather sample. The shrinkage temperature of Cassia singueana extract tanned leather recorded 83°C which is slightly higher than that of Mimosa extract (standard), 80°C. The results of mechanical properties such as tensile strength, tear strength, and elongation at break of Cassia singueana extract tanned leather sample are 15.6 N/mm2, 24.2 N/mm, and 45.3%, respectively, which are relatively higher than those of Mimosa extract tanned leather sample. A relatively higher reduction level of pollution load (BOD, COD, and TDS) was observed in the wastewater released from Cassia singueana bark extract compared to the Mimosa extract (standard). Finally, findings from this study revealed that Cassia singueana bark extract could be considered as an alternative source of vegetable tannins to reduce the consumption of chrome tanning in the leather tanning industry.
