Abstract

In recent years, Nuevo León, Mexico has presented hydric stress that, over time, has increased. Currently, the main bodies of water present a low level of this resource never before recorded. Due to the increase in freshwater, wastewater treatments must be proactive and sustainable to increase the circularity of water cycles. In this context, it is essential to replace the current approach based on a linear cycle towards a circular economy concept, in which waste is seen as a resource and with this implement strategies for the use of the different by-products in the wastewater treatment sector. . This project takes place in the Wastewater Treatment Plant (WWTP) Monterrey (Mty) in Nuevo Leon, México, which is considered the largest volume treated at the state level. Throughout its operation process, it generates different potential by-products. Four proposals were developed under a circular economy approach, which are: treated water for the industrial sector, residual sludge as organic fertilizer, cogeneration of energy from biogas, and sand and gravel as an aggregate of asphalt mixture. These proposals have the potential to generate benefits in the three pillars of sustainability. Resulting in a closed cycle in the wastewater treatment sector at national level.
