Abstract

Composting is a commonly used method for food waste treatment. However, a critical assessment of composting combined with bioelectrochemical systems (CBES) to produce direct electricity has scanty information in literature. In this study, food waste was composted, homogenized, and mixed with rice husks (RH) and coconut shells (CS) biochar. Then, the mixture was processed anaerobically for 30 days to get a stable and mature compost. This study also compared the anode surface area to analyze its effect on CBES performance. Then, the quality of compost, which includes the ratio of carbon and nitrogen (C/N), phosphorus (P), and bioelectricity production, was evaluated to obtain suitable conditions for CBES treating food waste. The results showed that 30% CS; and 20% RH could produce better quality compost. Therefore, the addition of 10% RH and three graphene in the anode chamber yield 4.71 mW/m2 and 6.56 mW/m2 of maximum power density. These results indicated that rice husk was considered to produce mature compost and better power density than coconut shells.
