Anaerobic digestion of Municipal Solid biodegradable wastes for methane production: A Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
The untreated and undisposed municipal solid waste generated through different sources is a major concern of the world now-a-days. There are millions of tonnes of municipal solid waste produced every year and the amount is rapidly increasing day by day. Anaerobic digestion is historically one of the oldest processing technologies used by human beings. Anaerobic Digestion is a multistep process in which the organic matter is degraded into a gas mixture of methane and carbon dioxide by microorganisms. It is a series of reactions during which organic material is decomposed through the metabolic pathways of naturally occurring microorganisms in an oxygen depleted environment. Anaerobic digestion could be an appealing option for converting solid organic wastes into valuable product like biogas, which plays an major role in the world’s ever increasing energy demand in the future periods. The full process occurs in four stages namely Hydrolysis, Acidogenesis, Acetogenesis and Methanogenesis. (Amani et al.,2010). Anaerobic digestion is a promising technology which could effectively address the problems of waste thereby yielding valuable outputs like biogas and fertilizers. Anaerobic digestion gives an opportunity to take responsibility for all the waste generated while ensuring environmental and economic benefits.
