MWM plant produces energy from biogas/landfill mix

17 May 2017

In late 2016, the waste management operator of the Alzey-Worms district commissioned an MWM cogeneration power plant in order to optimize the gas utilization. The installed TCG 2016 V16 gas engine is fueled with a mix of gas from the district landfill and biogas from the neighboring digestion plant. Since December 1, 2016, the MWM cogeneration power plant with its output of 701 kWel has thus enabled maximum efficiency and optimum utilization of the available resources.

Previously, two CHP plants had been in operation in Framersheim, using landfill gas and biogas separately. However, as a result of the decline in the amount of generated landfill gas since the shutdown of the district landfill in 2005, the operation of this CHP plant was no longer economically viable. But since methane gas from landfills is harmful to the climate and cannot simply be released into the atmosphere, a cogeneration power plant operated with mixed gas is exactly what the Alzey-Worms district needs.


The cogeneration power plant was set up by the long-standing MWM partner HGS from Krefeld. MWM partner Göbel Energie- und Umwelttechnik Anlagenbau GmbH from Büdelsdorf established the drying system. Both companies will continue to perform the required maintenance work on the gas engine and the entire CHP plant.

In 2017, the MWM gas engine is expected to generate 4.8 million kWh of power, an amount sufficient to supply 1,300 households with power. Most of the electricity will be fed in directly into the district's public grid. Thus, Heinrich Bräckelmann, Managing Shareholder of Schirmer Umwelttechnik GmbH, anticipates additional income of EUR 735,000 from the sale of the power. As the proceeds will be included in the budget and will thus benefit the consumers, it truly pays for the inhabitants of Alzey-Worms to collect biowaste.
