Abstract
This article analyzes the technical and environmental efficiencies of the MSW incineration industry across 16 cities and provinces in South Korea. The empirical results show significant variations in environmental efficiency, which range from 0.275 to 0.989 with a mean value of 0.912. The Gyeonggi-do region is the most environmentally efficient, while Busan is the least efficient. Moreover, some cities, such as Busan and Daegu, exhibit high technical efficiencies yet have dramatically low environmental efficiencies. Similarly, Seoul and Gwangju perform excellently in terms of environmental efficiency but have the lowest technical efficiencies. The output elasticity was calculated for each input, and the average output elasticity for CO2 is 0.090. Finally, the scale elasticity in the waste incineration industry was lower than 1.
