Tanneries in the municipality of El Cerrito are traditional industries, small and medium enterprises (SMEs), with economic importance for the region due to their intensive use of labor and exportingpotential. At the same time, they are characterized by a low productivity, raw material of low quality, technological obsolescence and high negative impacts to the environment. Great part of thiscontamination comes from the uncontrolled use of resources and raw materials in productive processes. This entails to industrial effluents without treatment with high levels of BOD, QOD, total suspendedsolids with chromium and sulfide in high concentrations, among others. These effluents contaminate the Cerrito River, affecting the population health and the quality of the water that is useddownstream for agricultural activities like sugar cane irrigation.
