This study examined the economic feasibility of applying the waste-to-energy incineration method in developing and emerging countries based on a case study of a 600 ton/day stoker-type incineration power plant in China. The effects of major variables such as the lower calorific value of waste, government power sales incentives, and corporate tax reductions on the economic feasibility of the project were analyzed. When the lower calorific value of municipal solid waste in Chiping county, China was 1,480 kcal/kg, the power sales incentive was 0.65 yuan/kWh, the waste handling fee was 93.7 yuan/ton, the internal rate of return (IRR) was calculated to be 6.61%, and the return on equity (ROE) was 6.50%, which showed that it is difficult to achieve economic viability. However, when the lower calorific value was 1,800 kcal/kg or higher, the internal rate of return (IRR) was 8.65%, and the return on equity (ROE) was 9.12%, which showed business model was economically viable. The factors that greatly affected business profits were the lower calorific value of waste and power sales incentive, whereas corporate tax reductions did not significantly affect business viability. The results show that there is a clear limit to sustainability when relying solely on government financial and policy support for the treatment of municipal solid waste.
However, if mechanical biological treatment (MBT), which has been shown to increase the low calorific value of waste, is applied as a pretreatment method, it is expected that the low calorific value of waste brought into the incinerator can be increased to an economically appropriate level of 3,400-4,000 kcal/kg or more.
