For over 20 years, the City of Dallas’ has been recycling garbage into a green energy at the McCommas Bluff Landfill. In 2017, along with Energy Power Partners, almost 2,000,000,000 cubic feet of natural gas (averaging 5,400,000 CFD) was manufactured and captured from the garbage the citizens of Dallas placed on their curbs and threw away elsewhere. That is enough gas to power approximately 70,000 homes. The natural gas at McCommas Landfill is captured, cleaned into a high BTU product, and put into a transportation pipeline to service homes, cars, and industrial sites across the nation.
To increase the production of landfill’s natural gas, an enhanced leachate recovery system treats the waste mass so that it can decay quicker resulting in greater methane production and lessened post-closure monitoring liabilities in the future. Enhances leachate recovery is a system that recirculates moisture containing beneficial microbes in the waste mass, accelerating the production of methane in the system. By capturing this gas, the City helps minimize the release of this greenhouse gas into the atmosphere and creates a revenue source for the City.
