Skins are considered a by-product of the meat industry, where 59% of the companies in Colombia are microenterprises and do not have the processes and technology necessary to treat the animal and to take advantage to leather (López and Hueza, 2018). Also, according to the Clean Production Guide for the Tanneries Sector of Bogotá (2015), this activity is characterized by excessive water consumption; disproportionate use of chemicals per/ ton of processed leather, with the tanning process being the most polluting. The current conditions of the production process in the company Cueros JCG cause a negative environmental impact that affects the community near the company, low productivity levels, and a high risk of penalties for non-compliance with environmental regulations. In this sense, the intention for this research is to understand the current conditions of the company and design a proposal to improve the retanned process that considers the incorporation of clean technologies, easily accessible and that in turn improves the hygienic conditions in the jobs in this company. This work observed that 75% of the risks identified affect health and life, 17.1% of hazards are contact and inhalation with chemicals such as paints, solvents, and anticorrosives, and 8.6% are related to unsuitable conditions of order and hygiene.
