    Actualidad de la reutilización y reciclaje de desechos provenientes de curtiembres, revisión en Ecuador y el mundo
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos y Biotecnología. Carrera de Ingeniería Bioquímica, 2022-09) Anchatipán Bastidas, Dayana Mishel; Flores Tapia, Nelly Esther
    Tanneries are industries whose main activity is leather tanning, to obtain products of commercial value such as: bags, shoes, wallets, jackets, belts, etc. The leather tanning process generates solid, gaseous, and liquid waste, with solid and liquid waste being the most abundant. These are discharged into water resources and landfills; due to toxic compounds they contaminate these ecosystems causing the death of their flora and fauna. Therefore, the application of recycling processes and reuse of solid waste and liquid effluents from tanneries for their use as raw material to manufacture value-added products and the reuse of the same wastewater for the tanning process. The basis of this research project consists in the collection of information using the Connected-Paper and RedCube-Paper software where it was found that the solid waste was used for the production of glues, hydrolyzed collagen, production of gelatin and amino acids, biofuels. , fatliquoring for leather and biogas, while chrome is recovered from liquid effluents for transformation into chrome salts reused as a tanning agent, which is why this project aims to make the feasibility of applying recycling and reuse process strategies that are used worldwide for solid waste and liquid effluents generated by Ecuadorian tanneries, promoting the reduction of these wastes and the reduction of the environmental impact caused by them in Ecuador.
