Each year, WM landfills process more than 100 million tons of waste combined, including common municipal trash and highly specialized materials like industrial waste. Items that cannot be reused or recycled often end up in one of our more than 250 landfills across the U.S. and Canada.
WM landfills are designed to protect the land and groundwater surrounding our sites. Our landfills use engineered liners and covers to keep contaminants in disposal cells, collection and control systems for landfill gas, as well as collection and treatment systems for leachate, the water that filters through waste in landfills.
