he Central Landfill Emscherbruch (Zentraldeponie Emscherbruch; ZDE) in Gelsenkirchen in the Rhine-Ruhr metropolitan region of Germany has been equipped with three new MWM TCG 3016 V12 gas generator sets fed by methane from waste dumps. The use of landfill gas as fuel for the gas engines saves costs and protects the environment. Across Europe large municipal or industrial landfills produce gas which can be tapped to generate electricity. Microorganisms that live in organic materials such as food wastes cause these materials to decompose. This produces landfill gas, typically comprised of roughly 60 percent methane and 40 percent carbon-dioxide.
