How does a waste-to-energy plant produce electricity?
Short answer
In a combustion-based waste-to-energy plant, a boiler recovers heat from burning waste to make steam. Steam drives a turbine-generator, and the facility may also export usable heat.
From the tipping floor to the grid
Waste is received and moved into a controlled combustion chamber. The boiler converts water to steam, and the turbine converts the steam’s energy to electrical output. Compare net electricity sold after on-site consumption.
What remains
Air pollution control equipment treats flue gas. The plant must manage bottom ash and fly ash. Ask for plant-specific ash and emissions data before drawing an environmental conclusion.
