Solid waste management in Malaysia displays more problems, including low collection coverage on average, irregular collection services, inadequate equipment used for waste collection, crude open dumping and burning without air and water pollution control, inadequate legal provisions and resources constraints. This problem contributes various impacts on the development of solid waste management system in Malaysia. Minimizing of landfill disposal method will be the objective of the propose research. Biological method wi1l be implemented to improve solid waste management in Malaysia such as anaerobic digestion. Anaerobic digestion has been suggested as an alternative method to remove high-concentration of organic waste. Many research groups have developed anaerobic digestion processes using different substrates. The propose study will be conducted in simulated landfill bioreactor (SLBR) of organic fraction municipal solid waste (OFMSW) from food waste. The reactor will be operated at temperature range between 45°C to 65°C (thermophilic conditions and with leachate recirculation). This reactor was analyzed for biogas production, methane gas production, COD, VFA, and TKN. Comparison study will be done within this reactor to find the most suitable condition (phase of reactor) to be applied to the recommended reactor. Food waste shows a great potential to generate energy, with the value of 1439KJ/kg due to its biomass property as a feeding substrate for microorganisms.
