The future solid waste management toward carbon neutralization will have to deal with problems on decreasing in the amount of burnable waste accompanying with population decreasing and promotion of 3R in each municipality. This study optimized the size and layout of incineration facilities and relay and transfer stations for municipal burnable waste in Hokkaido in 2050, regarding the total costs or energy. In the cost optimization, the effects of increase in the number of relay and tranfer stations on the cost reduction were large until the number of incineration facilities of 10, and the total cost was the lowest when the numbers of incineration facilities and relay and tranfer stations were 19 and 9, respectively. In the energy optimization, the net energy consumption was the lowest when the numbers of incineration facilities and relay and transfer stations were 1 and 20, respectively. These results are expected to be shared to enhance consensus building to integrate incineration facilities to be renewed until 2050.
