This paper presents a case study conducted at a food supply centre in a shopping centre in São Paulo city, Brazil. A waste digester was developed based on specifications provided by GE for the generator, and the cost of electricity production from food waste generated in the region was subsequently assessed. Results show that 1,368,750 m3 biogas was produced for the year, which provided a reduction of 14% of electricity consumption and is equivalent to USD 854 thousand per year. The amount of carbon credits is equivalent to 10,775 metric tons of CO2 and 51,840 tons of organic waste humus per year. The energy produced by biogas from food waste had a unit cost of 0.10 USD/kWh. At the end of the project, a profit of USD 3.087 million was achieved, which is equivalent to an ROI of 433%. There is a reduction in energy costs by USD 854 thousand per year and a payback of 1.01 years. These indicate that biogas production from food waste is economically viable.

“…Rapid economic growth in numerous cities has led to a high dependence on fossil fuels and gas for energy production, causing a significant increase in greenhouse gas emissions [1,2]. On the other hand, liquid bio-fuels (biodiesel y bio-ethanol) have been part of the strategies for reducing emissions of pollutants into the atmosphere.…”

The quality of waste activated sludge produced in urban wastewater treatment systems varies according to the efficiency of the operation of treatment units along the content of microflora and organic carbon. However, these represent a biogas-energy alternative through anaerobic co-digestion, contributing to reducing the environmental impacts caused by their inadequate disposal. Biogas production by the Two-stage production method in batch digesters was evaluated by two qualities of waste activated sludge (SLB50 y SLB90) and with a mixture of two co-substrates: cattle manure (CEV50 y CEV90) and residual edible oil with mixing, pH and temperature control. Bacteria in good quality sludge (SLB90) showed a faster adaptation of 2 days than those in low quality (SLB50) with 25 days lag phase. The highest CH4 production was for SLB90 (303.99cm3 d-1) compared to SLB50 (4.33 cm3 d-1); while cow manure sludge mixture (CEV90) contributed to increasing production of CH4 (42 422.8 cm3 d-1) compared to CEV50 (12 881.45 cm3 CH4 d-1), while in residual edible oil mixture they were 767.32 cm3 d-1 and 211.42 cm3 d-1 for CAV90 y CAV50, respectively. The addition of sludge co-substrates improves the nutrient balance, C/N rate and micro flora diversity; consequently methane production improves too; this methodology could be integrated into concepts of Circular economy.
