The research of Potential of Waste-to-Energy (WTE) in Malaysia aims to find out the potential of applying the process of Waste to Energy in Malaysia in terms of energy generated and potential revenue gained. Incineration and Anaerobic Digestion (AD) were the two methods that were taken to assess the feasibility to be run in Malaysia. The calorific value of the waste and the amount of waste generated were sought after before the energy calculations could take place. The waste generated was found to be 33,000 tonnes/day for the whole Malaysia while only 45% of the waste, which are the food waste, can be used for AD. Incineration can make use of most of the waste to produce energy while for AD, only methane that was produced from the food waste were used for energy generation. Thus, the calorific value of waste for Incineration and the amount of methane produced for AD were calculated. From those calculations, the electrical energy that could be generated using the total waste produced in Malaysia using Incineration was found out to be 68 GWh while for AD was 16 GWh. The results showed good potential to apply the processes in Malaysia as these wastes can provide value when, at the moment, it is being thrown away. Comparatively, Incineration is better than AD based on this research as the amount of waste is considerably larger than the amount of methane that could be produced.
