Covanta Delaware Valley, in the City of Chester, Pennsylvania, is the nation’s largest trash incinerator, burning up to 3,510 tons of municipal and industrial waste every day. They’re the largest air polluter in Chester City and one of the top few air polluters in the 7-county Philadelphia region. They operate without two of the four pollution control devices common to trash incinerators. Trash incineration, even with all of the normal pollution controls, is more polluting than coal power plants, and is worse than landfilling the waste directly. When burning trash, 30% of it becomes toxic ash that makes landfills more dangerous to groundwater. The other 70% becomes air pollution. The toxic ash from Covanta Delaware Valley is dumped in the Delaware County Solid Waste Authority’s Rolling Hills Landfill in Berks County, PA.

Covanta Delaware Valley has accepted waste from 21 Pennsylvania counties, 14 other states (as far as Oklahoma), Puerto Rico, and Canada. In 2020, they burned an average of 3,391 tons/day, with 31% coming from Philadelphia, another 31% from Delaware County, 17% from DE (most/all of which is rerouted Manhattan trash trains that go through Chester on train, then is transloaded onto trucks in Wilmington to be trucked back into Chester), 16% from NJ, another 4% from NY, 1.6% from MD (all or nearly all from Ocean City), and less than 1% from 4 other PA counties plus NC and VA. Just about 1.8% of the total is Chester City’s trash. Learn more about Covanta’s waste contracts.
