摘要

The management of municipal solid waste (MSW) is a growing environmental challenge in Ecuador, where open dumps remain the most common destination for urban waste. This study analyzes the composition and physical characteristics of MSW in the canton of Balzar (Ecuador) through surveys, technical visits, and physical characterization of MSW (application of ASTM D5231-92) to identify alternatives for reuse within the framework of the circular economy. The methodology used was: i) Diagnosis of MSW management in the Balzar canton, ii) Characterization of MSW, iii) Proposals for environmental strategies, applying a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis and evaluation of technologies for managing and recovering MSW. The results indicate that organic waste accounts for 59,74% of the total waste, followed by disposable diapers (10,90%) and plastics (11,8%), with a moisture content of 64,9% and a calorific value of 11,1 kJ/g. Based on these data, six management and recovery technologies were evaluated, with composting (COM), waste derived fuel (WDF), and landfill (RS) standing out as the most suitable. The SWOT analysis enabled the definition of strategies such as strengthening strategic alliances (with private entities), organizing recycler networks, and improving the operational efficiency of the Waste Disposal Site (WDS) by incorporating technologies for waste treatment and recovery. The current WDS does not comply with current environmental regulations because it is an open-air dump and poses problems such as contaminating nearby soil and water bodies, attracting vectors, and causing air pollution. A transition to a comprehensive and circular management model is recommended, requiring joint action among the municipality of Balzar, the Prefecture of Guayas, and other actors (academic or private companies) to fulfill Sustainable Development Goals (SDGs) 9, 11, 12, and 13.
