Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen it is used for industrial or domestic purposes to manage waste and/or to release energy. Anaerobic digestion of waste bioplastic depending on the rate of bioplastic fermentation in a biogas digester, biodegradable bioplastics can be digested to assist in producing methane if all plastic packaging used for food was biodegradable, it would hold big advantages for food waste anaerobic digestion plant operators.
According to the american biogas council, anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen the products of this process are biogas, liquid digestate, and solid digestate a similar process occurs. Global methane initiative food waste anaerobic digestion biogas and digestate remove non-biodegradable materials and homogenize the. Waste-water with high biodegradable content and high temperature, such as industrial waste-water, is more suitable for anaerobic processes introduction top : the process of anaerobic digestion is decomposition of biodegradable material by micro-organisms in the absence of oxygen.
Anaerobic digestion occurs naturally, in the lack of oxygen, as microorganisms break down biodegradable materials (like food waste) the two traditional anaerobic digestive processes (mesophilic and thermophilic digestion) generally require temperatures ranging from 20 - 70°c. How anaerobic digestion can be used to treat biodegradable waste. The benefits of anaerobic digestion of food waste easily biodegradable - food waste is highly biodegradable and has a much higher summary of parameters.
