Anaerobic Digestion of Municipal Solid Waste: A Critical Analysis

Abstract

The undisposed and untreated amount of municipal solid waste (MSW) generated by different sources is a concern of the world today. There are millions of tonnes of solid waste being produced every year and amount of MSW is increasing day by day. Co-digestion of waste with other substrate mechanism may be used to decompose the maximum biomass waste generated from different source. The MSW has to be safely disposed without any negative impact to the environment. On the other hand, the generation of energy from renewable sources of energy due to depleting natural non renewable sources of energy has been becoming world’s main interest. The MSW can be one of the energy sector dreamt by the world today by use of co-digestion process. Also, the energy produced by non renewable sources of energy contributes to environmental problems such as water, land and air pollution or even global climate change. Anaerobic co-digestion as a pre-treatment prior to landfill disposal or composting offers several advantages, such as minimization of masses and volume, inactivation of biological and biochemical processes in order to avoid landfill-gas and odour emissions, reduction of landfill settlements and energy production in the form of methane. Furthermore, codigestion of biowaste with other substrate can be considered as an alternative option to improve the environment condition caused by organic solid waste and at the same time taking an advantage as an environmentally-friendly resource of energy. In this paper a critical analysis of some research papers in the field of anaerobic co-digestion process is done
