【 摘 要 】

Slums are populated poor areas inside urban centers, mostly deprived of good-quality public services and exposed to inappropriate waste disposal and energy poverty. Using the organic fraction waste from these communities to generate high value-added products, including electricity, heat, and fertilizer, provides a circular bioeconomy with mitigation of greenhouse gas emissions, reducing environmental pollution and diseases. The present study aimed to demonstrate the feasibility of producing bioelectricity from the biogas obtained through the anaerobic digestion of the 400,000 tons of food waste generated in São Paulo’s slums, the largest city in Latin America. The biogas potential was calculated using results obtained from previous studies, expanded to the slums, mapped, and discussed the environmental impact of waste mismanagement and the renewable energy source (RES) integration into the local energy system. The results show a bioelectricity potential of up to 147,734 MWh/y, representing 1.3% of the residential electricity demand with an associated potential reduction of 2111.7 CO₂eq Gg/y.
