The Piyungan landfill in Indonesia has a daily waste tonnage of 600 tons, mostly organic and combustible waste that can be used for energy. The study aimed to assess the energy potential of the waste based on its characteristics, like moisture content and calorific value. Results show that the landfill contains mainly organic waste and RDF, with high moisture content in the RDF. Different technologies like landfill gas, anaerobic digestion, gasification, and incineration can generate energy ranging from 1.2 MW to 9 MW, depending on the type of waste and technology used. This information can help in choosing the right technology for generating energy from the waste in an economically feasible way.
