Abstract

The integration of sustainable energy generation with efficient organic waste management offers a compelling opportunity through the application of microbial fuel cell (MFC) technologies. This study explored the enhancement of performance in soil-based MFCs through the utilisation of vermicompost sourced from Eisenia fetida, aiming to boost bioelectricity generation. Three configurations were assessed: a control (black soil), a compost-enhanced MFC (WMFC), and a vermicompost-integrated MFC (VMFC), with regular organic waste feeding conducted over a 50-days duration. The analysis focused on electrical outputs, soil pH dynamics, surface morphology of copper anodes, and electrochemical impedance spectroscopy (EIS). The findings indicated that VMFC demonstrated exceptional performance, reaching a peak voltage of 0.80 V, a current density of 10.764 mA/m² and a power density of 5.056 mW/ . This success can be linked to increased microbial activity and effective electron transfer, which were supported by the decomposition of substrates mediated by earthworms. Scanning electron microscopy (SEM) imaging revealed significant biofilm formation on VMFC anodes, whereas EIS demonstrated minimal charge transfer resistance. The results highlighted the combined impact of vermiculture and microbial groups in enhancing MFC efficiency, presenting a scalable approach for bioenergy production and the value addition of organic waste in sustainable environmental systems.
