“…En la figura 2 se muestra el incremento del tema en Scopus: Como se muestra en la figura 2, el número de publicaciones sobre el tema ha aumentado con el tiempo a partir del año 2000, lo que refleja que el interés de la investigación en temas de gestión ambiental en la industria de la moda, especialmente del cuero, se ha ido desarrollando. Se destaca en los últimos años el desarrollo de temáticas hacia la economía circular (Hildebrandt et al, 2021;Hu et al, 2011;Mizrachi y Tal, 2022), la implementación de nuevas tecnologías en cambios de materias primas (Jia et al, 2020;Masilamani et al, 2016;Velappan et al, 2022) y la comprensión de los impactos provocados por la estructura productiva (Johnson y Plepys, 2021;Laitala et al, 2018;Shen y Li, 2015), aspectos que también exigen una investigación académica sobre nuevas prácticas, estrategias y herramientas de gestión ambiental en su contexto.…”

The purpose of this research is to analyze the literature around the leather tanning industry, based on a systematic review of literature in the SCOPUS database, whose objective was to conceptually analyze sustainability aspects from the content structure, environmental, social aspects and governance. The search equation yielded 785 articles in SCOPUS, which once filtered resulted in a total of 20 articles for in-depth analysis. To visualize the information, the VosViewer tool was used, which made it possible to represent the existing co-citation and co-authorship relationships through clusters. The results show what the background is, the topics of interest for academics, the countries with the longest history of research in the area and the collaborative work networks, as well as the most relevant authors and studies in this field and the impact trends. from the fashion and leather industry about sustainability.

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.

“…Una de las fabáceas con un alto contenido de taninos es la Anadenanthera Colubrina (Huilco), en la cual se ha encontrado 13.95 % de taninos condensados en la corteza del tronco, seguido de la corteza de la raíz con un 10.37 % [8]. Por otro lado, también se ha reportado la presencia abundante de taninos en Azadirachta Indica (Neem) [4] y Paraserianthes Lophantha (Albizia Amarilla) [9].…”

In the leather industry, chromium sulfate is primarily utilized in the process of leather tanning, which poses risks to both human health and the environment. In the present investigation, the tannin content present in the fabaceae species Anadenanthera Colubrina and Paraserianthes Lophantha is analyzed, verifying that they possess the necessary amount of tannins required to operate as a tanning agent. The taxonomic identification of both species was carried out, determining that they belong to the Fabaceae Lindl family. The aqueous extraction of tannins from pods and seeds of both species was carried out, to later perform the quantification of total and residual polyphenols, using the spectrophotometric method, and under an absorbance analysis it was possible to determine the concentrations of each extract. The percentage of tannins present in each sample was determined, giving as a result that ParaserianthesLophantha is the forest species with the highest tannin content in pods with a total of 0.99 %, followed by Anadenanthera Colubrina, which has 0.96 % of tannins in seeds. Therefore, the vegetable residues of both Fabaceae can be considered for the creation of a vegetable tanning agent, representing a good alternative to replace chrome salts in the leather tanning process.
