America's 10 Largest Landfills

America's 10 Largest Landfills

Posted by Trashcans Unlimited on 30th Nov 2022

America generates over 290 million tons of trash every year. According to the EPA, more than 146 million tons of this waste ends up in landfills. While most people would see waste as a threat to the environment, landfill owners see a profitable business opportunity. They make money and protect the environment simultaneously.

Two giants in the garbage industry are Republic Services and Waste Management. Leveraging modern technology, they turn trash into money by tapping into landfill gas and selling it to local authorities and businesses.

Below, we've created a list of the largest landfills in the U.S. that create a fortune from Americans' garbage.

Between 500-600 truckloads of municipal solid waste (MSW) end up in Sunshine Canyon per day. This equals about 45,000 tons of garbage weekly and 2.5 million tons yearly.
