 This study compared three waste energy technologies, landfill gas recovery, incineration, and anaerobic digestion for Panam-Pen municipality in Cambodia. It evaluated their energy potential, economic feasibility, and environmental performance. The study concluded that incineration produced the highest energy output, followed by landfill gas recovery and anaerobic digestion. Economically, incineration and landfill gas recovery were found to be feasible with positive net present values and potential for profit within eight and seven years, respectively. Anaerobic digestion, however, was not economically viable due to its high costs and long payback periods. Environmentally, incineration was the most promising technology, as it saved the most carbon dioxide emissions. Overall, this study provides valuable technical information for policymakers, development partners, and potential investors to use when making decisions about waste-to-energy investments in Cambodia.
