This research aims to study electrical energy providing from waste by combustible waste and non-combustible waste to solve the problems of municipal solid waste management. Research study includes physical and chemical elements of waste, heat from combustion waste with bomb calorimeter, and the production of methane from non-combustible waste by two-stage anaerobic digestion. The result indicated that waste in Municipality Promlok was an average amount of 3.47 tons per day, with organic waste 41.67 percent by weight, and plastic 25.83 percent by weight. The waste can be classified as the combustible waste, non-combustible, and trash with 43.33, 48.33 and 8.33 by weight of waste, respectively. The composition of combustible waste consisted of moisture (36.94 %w/w), total solids (63.06 %w/w), and volatile solids (19.02 %w/w). Those of non-combustible waste were 77.79 %w/w moisture, and 22.21 %w/w total solids. The non-combustible waste was mixed with methane-producing inoculum for biogas production. The effect of non-combustible waste loading (3, 5, 7, 9, and 11 %w/w) on the performance of hydrogen and methane production via two-stage anaerobic digestion was investigated.  Two-stage anaerobic digestion of non-combustible waste of municipality Promlok was found maximum hydrogen, and methane production for 3 (%w/w) substrate loading has the largest concentration of 3 percent municipal waste. The methane production was 114.76 m3-CH4/tonne-VS, with a heating energy potential of 418.63 kWh/day. At the same time, the electric production potential of combustible waste was 2,729.62 kWh/day.
