Design technology for bioenergy conversion of organic fraction of municipal solid waste

In this study, we investigated the use of a laboratory batch anaerobic digester technology, for biochemical methane potential (BMP) and the bioenergy process design from anaerobic co-digestion of different organics fraction of municipal solid waste (OFMSW) originating from the city’s landfills. The carbon-to-nitrogen (C/N) ratio of OFMSW was found to be below 13. Through co-digestion, the C/N ratio settled at 14. Laboratory experimental data from 500 ml batch anaerobic digester operating at mesophilic temperature of 37 °C and pH of 7 had good productivity of methane of average 59.49% with (54–62%) recommended in the literature and was used to derive volume of digester and surface area. Via the application of the simple multi-attribute rating (SMART) technique of multiple-criteria decision analysis (MCDA) as a decision support tool, the most preferred model option for bioenergy design technology was selected from a list of potential alternatives available in the market. The geometry of the biodigester parameters was comparable with the process.
