Title: Landfill gas and its renewable energy potentials in Johor, Malaysia
Abstract: Emission of landfill gas (LFG), a greenhouse gas (GHG), from unmanaged Landfills is a major challenge particularly in growing economies. On the other hand, this is a potential resource for renewable energy. Landfill gas (LFG) which is essentially methane (50 - 55%) and carbon dioxide (40 - 45%) is generated in landfills by biodegradation processes of municipal solid waste, MSW. Landfill gas generation/emission concepts and the quantification of its potentials as a green energy resource for environmental sustainability in Johor state is the aim of this study. Using Intergovernmental Panel on Climate Change (IPCC) methodology, it was discovered that there is a significant emission of LFG from the 14 landfill sites in operation in the state. Based on 1,086,205 metric tons of MSW received per year by the landfills, 46,320 metric tons of methane LFG per year is emitted. 60% of this emission, when captured, has the potential to generate over 171 million kWh of electricity per year worth over US$17 million (RM51 million) when well utilized. In addition, it can lead to carbon dioxide reduction of 583,632 metric tons per year equivalent to carbon credit of over US$7.7 million (RM23 million). Furthermore, the exploitation of this resource, besides the economic and environmental advantages, will help in reducing the dependence on the depleting fossil fuel and hence broadening the fuel base of the country.
