Analysis of the biogas productivity from dry anaerobic digestion of organic fraction of municipal solid waste

In this study, it was observed that in experimental work under laboratory scale using conventional biomethane potential (BMP) analyser under the mesophilic optimum temperature of 37 °C and pH of 7. Organic fraction municipality solid waste (OFMSW) inoculated with cow manure had higher biodegradability rate leading to high methane production under shorter hydraulic retention rate. The co-digestion of OFMSW and cow manure stabilises conditions in digestion process such as carbon to nitrogen (C: N) ratio in the substrate mixtures as well as macro and micronutrients, pH, inhibitors or toxic compounds, dry matter and thus increasing methane production. It was concluded that the organic waste generated in the municipality co-digested with manures to produce methane can be used as a source of sustainable renewable energy.
