In tanneries, animal skins of different origins are transformed into a hard, flexible and resistant material called leather. In many countries it represents fundamental segments in their economies, although Colombia is a small producer compared to other countries such as China and Italy, for the country it is an important sector for its economy, the largest producers being the departments of Atlántico, Antioquia, Cundinamarca and the city of Bogotá, in the San Benito neighborhood. Among the main problems of these industries are the large amounts of water consumed in each production unit, along with its treatment and the sludge generated at the end of each process, which are currently considered hazardous waste. With this thesis, it was sought to characterize the sludge from each production process and non-domestic wastewater treatment units, in order to identify if they truly have any dangerous characteristics in accordance with IDEAM Resolution 062 of 2007, at Based on this, if it were, we proceeded to identify from studies carried out which alternative management alternatives could be carried out other than the final disposal. Once the study was carried out, it was found that the sludge from the non-domestic wastewater treatment plant has flammability characteristics, the fur and vegetable tanning are ecotoxic from the results obtained in the tests carried out, to These were found biological, thermal, physical alternatives or studies where they were used as raw material for the elaboration of new products, concluding that although different management alternatives have been studied, the addition of tannery sludge for the co-processing of cement can be the most viable option to manage all types of sludge, since as long as the flue gas is properly managed, no harmful gas emissions would be generated, the use of coal which is normally used in the process, sludge can be added up to 0.7% of the feed composition and the cement quality is not altered.
