Long-term anaerobic digestion (AD) of food waste often faces challenges, with volatile fatty acid inhibition being a common issue that hinders optimal performance. This research explores the effect biochar supplementation on long-term AD characterized by inhibition. The findings demonstrate adding modest amount (0.055 g/L) effectively enhances under ambient conditions at 29 °C. reduced acids to safe level 1195 mg/L after 36 days, well within generally accepted threshold 1500 mg/L. is supported other studies, which indicate maintaining VFA concentrations below minimizes risk process and ensures stable operation. Additionally, normalized specific biogas yield averaged 1.33 ± 0.45 m3/kg VS, representing 47.4% improvement over control conducted identical conditions. After stabilization, study assessed whether could maintain functionality stability mesophilic (35 °C) without further supplementation, simulating real-world scenario test efficacy in industrial-like postbiochar resulted an additional 31.8% increase average yield, reaching 1.95 0.25 VS. Biochar increased Methanosaeta methanogens 30%, enhancing direct interspecies electron transfer strengthening syntrophic interactions. shift made aceticlastic 9 times more prominent, improving acetate oxidation, overall stability. These highlight biochar's potential enhance decentralized facilities, promote sustainable management, advance bioeconomy providing replicable model for closing loop.
