In this room, you can see a large metal box, which is one of three combustion chambers. The combustion chambers, or boilers, burn between 800°F and 2,000°F. That’s hotter than lava! Each day, 1,000 tons of waste is put into each combustion chamber. The heat from this combustion super heats water in pipes, and the steam is used to spin a turbine that generates electricity. Renewable Energy Facilities 1 and 2 generate enough electricity to power about 90,000 homes per year.
