Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

Year: 2026

Type: article

Abstract: ABSTRACT Around 1.3 billion tons of food is wasted globally per year, producing 3.3 billion tons of CO 2 . Anaerobic digestion (AD) of food waste (FW) is a sustainable and economical solution to this crisis, which produces biogas and aids in environmental protection by sequestering methane, a potent greenhouse gas. The nutrient‐rich digestate slurry can be used as a bio‐fertilizer. Thus, this process enhances logistics, reduces pollution, and facilitates resource recovery by lowering waste volume and transportation cost. This review article is divided into sections on FW classification, the biochemical pathway in AD, the microflora involved, key operating parameters, limiting factors in AD, and the use of additives to enhance biogas production. It also covers the current research gaps, challenges, and future perspectives. The findings demonstrated AD as a viable technology for converting FW to biogas. It will expand the knowledge of sustainable and scalable biogas generation by combining FW heterogeneity with cutting‐edge AD methods, which can significantly improve the economic and commercial feasibility of FW valorization, pilot‐scale productivity, and energy recovery in real‐world applications.
