Application of Cleaner Production in Esmeralda Corp's Wastewater Treatment Plant

ABSTRACT Currently, industrial wastewater treatment plants (WWTPs) have not been studied with respect to cleaner production strategies as opposed to the productive sector. The objective was to evaluate the application of production strategies in the WWTP processes over a period of 4 years. For this purpose, the methodology recommended by UNIDO was used. The results indicated that throughout the life cycle they have been satisfactory, due to the implementation of activated sludge technology and ultrafiltration membranes to obtain quality water for irrigation of green areas, compliance with the Environmental Quality Standard, removing more than 99% of BOD and COD. The average savings are equivalent to 410,625 m 3 , having a positive impact on stakeholders, as well as a CO 2 reduction of 143.71 t CO 2 /year. Finally, it complies with the Sustainable Development Goals, contributing value to society.
