Harnessing food waste potential: Biochar driven waste to energy conversion for methane generation

This study explored the optimization of anaerobic digestion (AD) of organic wastes through the strategic integration of electrically conductive biochar particles. Electrically conductive biochar facilitated electron transfer among microbial populations, enhancing methane production in AD systems. The research investigated microbial profiles, metabolic pathways, and physicochemical factors to elucidate the mechanisms underlying enhanced methane generation. By strategically incorporating biochar, this study enhanced understanding of its pivotal role in optimizing complex microbiological processes within AD systems. The findings underscored biochar's critical role in enhancing the effectiveness and adaptability of AD systems, thereby advancing environmentally friendly waste-to-energy technologies. This research advocated for innovative biochar-based solutions to address contemporary challenges in waste management and renewable energy production, emphasizing a significant 11% increase in methane production compared to traditional methods.
