SUSTAINABLE SOLUTIONS FOR INDUSTRIAL WASTEWATER MANAGEMENT USING PERMEABLE CONCRETE AND WATER REUSE FOR FLEET WASHING WITHIN THE FRAMEWORK OF THE CIRCULAR ECONOMY: CASE OF THE COMPANY CONCRETOS DE SINCELEJO

One of the main environmental problems in Sincelejo (Sucre) is the inadequate disposal of industrial wastewater, much of which is discharged untreated into the urban drainage system, affecting surface and groundwater bodies. This research proposes a treatment system based on permeable concrete, designed with local materials, allowing for physical filtration of water and its subsequent reuse in activities such as fleet washing (vehicles, machinery, and equipment). Industries with a high environmental impact were identified to implement a low-cost, efficient, and sustainable solution aligned with the principles of the circular economy. The intervention at a concrete plant and a car wash company yielded positive results, demonstrating measurable environmental and economic benefits
