Climate Science students visited Covanta Energy from Waste, a a waste solution for Marion county. In the process of burning the landfill refuse, Covanta reduces the volume of waste by 90%, resulting in ash that is used as landfill cover. They also recover ferrous and non-ferrous metals that are recycled. The plant produces about 13 MW of electricity. 3MW are used to run the facility, and the remaining power is fed back into the grid.
