garbage processing plant; waste incineration plant
Refers to a facility where collected waste is processed, often by incineration. Common in municipal contexts.
The garbage from this area is incinerated at the waste processing plant.
I went on a tour of the waste incineration plant.
ごみ処理場 is a broader term for any garbage disposal site, while 清掃工場 specifically implies a facility with processing or incineration capabilities.
Compound of 清掃 (cleaning, sanitation) and 工場 (factory, plant).
