Anaerobic digestion (AD) is a preferred method for food waste (FW) treatment due to its sustainability and potential production of renewable bioenergy. However, the accumulation volatile fatty acids (VFAs) ammonia often destabilizes AD process, managing digestate byproduct poses additional challenges. This study investigates use co-pyrolysis biochar synthesized from rice straw (DRB) enhance methane efficiency. DRB addition increased cumulative yield by 37.1%, improved VFA conversion efficiency, achieved 42.3% higher NH3-N-removal rate compared control group. The COD-removal was 68.7% throughout process. Microbial analysis revealed that selectively enriched Fastidiosipila Methanosarcina, promoting direct interspecies electron transfer (DIET) yield. These findings highlight DRB’s efficiency support closed-loop resource utilization.
