Analytical approach for predicting biogas generation in a municipal solid waste anaerobic digester
The increasing worldwide industrialization, urbanization and population explosion in major metropolitan cities have significantly affected the amount of wastes generated from municipal solid wastes (MSW). Beukering et al., (1999) accounted for industrialization as an important factor that increases waste generation. Anand (1999) focused on urbanization as an important variable in waste generation, while Halla and Majani (1999) emphasized on population explosion as an important determining factor in waste generation. Thus, if these wastes are not properly managed, they may pose a severe threat to the health status of humans and their activities (Onibokun, 1998). With over 80% of the industries in Nigeria located in the industrial cities of Lagos, Kano and Port Hacourt (Ojeshina et al., 1996), the need to strongly pursue the conversion of wastes generated into fuel (biogas) to reduce its nuisance value to the environment is important. Wastes have been effectively used as biogas materials by various studies. Isci and Demirer (2007) examined the biogas potential of cotton wastes. Verma et al., (2007) investigated biogas production from plant biomass used for phyto-remediation of industrial wastes. Gelegenis et al., (2007) optimized the biogas production from olive-oil mill waste-water by codigesting with diluted poultry-manure.
