1 cze 2018 · Anaerobic digestion (AD) and composting are two plausible approaches for organic waste management and nutrient recycling, and both technologies closely interact within the FEW nexus (Fig. 1). AD is an anaerobic biological process that converts organic matter to biogas and digestate [3] ( Fig. 2 ).
Anaerobic digestion is a sequence of processes by which microorganisms break down biodegradable material in the absence of oxygen. [1] The process is used for industrial or domestic purposes to manage waste or to produce fuels.
1 gru 2023 · The anaerobic-aerobic process allows for high removal of organic contaminants. •. Compost application helps sustainable biomass production and C sequestration. •. Biogas production should be enhanced to reach economic sustainability. Abstract.
18 lis 2014 · Is anaerobic digestion better than composting for managing source separated organics? It depends. On project specific factors, anaerobic digestion (AD) is a good bet economically and technically in some situations, and composting (and sometimes other approaches) is right for other circumstances.

In anaerobic composting, decomposition occurs where oxygen (O) is absent or in limited supply. Under this method, anaerobic micro-organisms dominate and develop intermediate compounds including methane, organic acids, hydrogen sulphide and other substances.
23 kwi 2024 · Anaerobic digestion is the transformation of organic matter by a complex microbial community (or consortium), in the absence of oxygen, into a biogas composed mainly of 55 to 75% methane (CH 4) and 25–45% carbon dioxide (CO 2).
