Waste to Energy Plants
This facility burns waste and treats it hygienically, while at the same time generating electricity as an important energy resource.
Refuse brought to the refuse pit by garbage trucks is burned while moving on top of a combustion device called a stoker in an incinerator. The incinerated refuse is then discharged as ash. The energy of exhaust gas generated by combustion is recovered as steam by the boiler, and electricity is then produced by the steam turbine generator. The generated electricity is also sent outside the facility.

- Largest share of global market in terms of processing capacity (2015 ~ 2024)
