| Summary: | Municipal solid waste (MSW) generation that grows continuously without proper
management become worrying phenomenon. Currently, Malaysia is dependent on landfills
with almost 85% of waste collected ending up in dumpsites. In order to propose an alternative
for solid waste management plan instead of landfill, and to develop a waste-to-energy (WtE)
system, the details study of municipal solid waste (MSW) generated is crucial. This paper
presents a proposal for energy recovery to produce RDF by studying the characterization of
MSW generated in Malaysia; the physical and chemical properties (proximate and ultimate
analysis, calorific value or energy content, and thermal analysis) of the waste components to
produce a high-quality RDF. The raw MSW sample consisted of 45% organics and food
waste, 13% plastics, 9% papers, and 12% diapers. For raw MSW sample, total moisture
content, ash content, volatile matter, and fixed carbon were 14.60%, 7.05%, 69.35% and 9%
respectively. Gross calorific value is 4538 kcal/kg and carbon content are 45%. The optimum
produced RDF sample was found at operating temperature 400°C with total moisture content,
ash content, volatile matter, and fixed carbon were 0.75%, 21.65%, 48.35% and 29.22%
respectively. Gross calorific value is 6600.15 kcal/kg and carbon content are 64%. |
