Abstract

Garbage management and the use of waste are part of sustainable development goals (SDGs) 8, 11, and 12. The recycling process is simple and contributes to improving the environment. Therefore, garbage management in Ecuador is a relevant issue that society must address regardless of the size of the community that generates it. In this case, university campuses need services and infrastructure, including waste management at the scale of a small city, because they require services like these (e.g., accommodation, transportation, cleaning, and waste management). This research seeks to propose the ideal location for a separation, assessment, and recycling center (CSVR), through the implementation of a multi-criteria matrix, with the application of the vertical electrical sounding techniques (SEVs), for the sustainable management of waste. The methodological process includes: (i) identification of probable sites; (ii) application of a multi-criteria matrix for CSVR; (iii) application of geophysical methods (SEVs); and (iv) interpretation of results and selection of suitable areas for the recycling center. Six sites were analyzed, of which three were ideal for the implementation of SEVs where there will be control and management of invasions, as well as non-contamination of water resources. All the selected areas are permeable in their superficial layer and favor leaching; therefore, waterproofing at its base and some design criteria that contemplate technical and environmental monitoring were recommended.
