National human population, economy development and advancement of technologies have led to a high demand of energy. Despite this, depletion of conventional fuels and global warming crisis are hindering the government to fulfil the citizens’ needs. One of the options to solve the problems is by implementing Waste-To-Energy (WTE) systems which in general, can convert or process any type of wastes into energy. Apart from being an alternative energy resource, WTE is also able to relieve the conflict of disposal of wastes in the country. Therefore, this paper aims to review the energy, economic and environmental impacts of WTE in the country. As organic wastes are dominating the overall wastes in the country by 57.39%, this paper focuses on biomass and organic wastes such as sewage sludge, crop yield, animal wastes and municipal solid wastes (MSW) as potential source of energy.
