Feasibility study of municipal solid waste for producing refuse-derived fuel (RDF): A case study of Bangkok, Thailand

N Eaktasang, Y Suma, S Kingkeaw

Abstract The objective of this study was investigated the potential of municipal solid waste (MSW) to produce refuse-derived fuel from Bangkok municipality. The composition, heating value and proximately content were analyzed. The amount of MSW in Bangkok generated was approximately 4.86 million tons or 13,327 tons/day in 2017. About 79.5% was disposed by landfill and 20.5% was recycled. The compositions of MSW were biodegradable (49.58%), combustible (36.32%) and non-combustible (14.10%) wastes. Moisture content was 59.5±8.6% (as received), volatile matter, fixed carbon and ash were 72.4±3.2%, 8.2±0.5% and 19.4±0.5% (as dry basis), respectively. Heating value was 20.03±0.52 MJ/kg. These results indicated that MSW from Bangkok municipality is potential to produce the refuse-derived fuel. To reduce the environmental impacts as well as energy recovery, the MSW might be alternative sources of renewable energy in the future.

The dynamics of some physical and physico-chemical properties during composting of municipal solid wastes and biomass of energetic plants

Andrea Kałuża-Haładyn, Elżbieta Jamroz, Jakub Bekier

Abstract The aim of the research was to analyze the composting process with respect to changes in some physical and physicochemical properties of the organic part of municipal solid waste and willow and hay biomass mixture. The dynamics of changes in cation exchange capacity CEC values in relation to the base value of the initial materials of both tested composts were higher for municipal solid wastes compost (MSWC) compost than for willow biomass compost (WBC). The dynamics of pH changes were similar in the tested types of compost and were rather small during the process of composting, regardless of the type of organic residues and initial reaction. During composting process, the transformation of organic matter and mineral components slows down after reaching a stabilization phase.
