waste-to-energy

Burning garbage productively

Waste-to-energy refers to processes that convert garbage and other refuse into usable power, typically electricity or heat.

Incineration is the most common method, though gasification and anaerobic digestion also qualify.

The approach reduces landfill volume while generating power, though critics raise concerns about emissions and the disincentive to recycle: The city built a new waste-to-energy plant.
