Abstract
As the second-largest city in Taiwan, the Kaohsiung municipality has faced serious environmental loadings in recent decades. Among them, waste management is a key issue because of large amount of urban and industrial waste produced daily. In this regard, waste-to-energy (WTE) systems adopting the best available control technology for air pollution is a win-win approach because it also generates electricity to mitigate the dependence on imported fossil fuels and the greenhouse gas emissions incidentally. In this work, the updated status of municipal solid waste (MSW) and WTE plants in Kaohsiung were analyzed to get the crux based on the official database. Using the operational data on the WTE plants over recent years (2003–2018), the analysis of operational efficiencies for the four WTE plants in Kaohsiung was addressed in the paper. It showed that their operational efficiencies, ranging from 0.287 to 0.568 kW-h/kg, indicated an approximate “bathtub curve” pattern. In addition, analyzing the project for revamping the Gangshan WTE plant showed a significant progress in operational efficiencies with a significant increase from 0.506 kW-h/kg in 2016 to 0.587 kW-h/kg in 2018. Finally, some recommendations on technological measures and regulatory incentives for upgrading the operational efficiencies of existing WTE plants were addressed in the work.
Highlights
Some recommendations on technological measures and regulatory incentives for upgrading the operational efficiencies of existing WTE plants were addressed in the work
To upgrade the administrative effectiveness, the Kaohsiung city merged with the Kaohsiung County to form a larger special municipality on Dec. 25, 2010
The WTE plant is economically feasible with medium payback period and high net present value mainly due to the significant gains from sales of electricity in some Asian countries such as Thailand [11], Malaysia [12], and China [13]
Summary
Geographically located in the southeastern rim of Asia, faces the Pacific Ocean in the east and the Taiwan Strait in the west This subtropical island country has a high population density (about 606 people/km2 ) based on its total area of ca. As the second-largest city of this island country, the Kaohsiung municipality (hereinafter referred to as Kaohsiung) is in southern Taiwan, having a warm climate with mean temperatures between 20 and 29 ◦ C. It is one of six special municipalities, which were officially authorized by the Taiwan government. The features of this municipality at the end of 2018 are as follows: Population: Approx. 2.8 million
