Entsorgungswirtschaft Soest GmbH (ESG) awarded a tender on 25 September to construct a plug-flow digester with gas conditioning at its composting plant in Anröchte, Germany. HZI won the tender and will construct the entire digestion section over the next 15 months. This is Germany’s 22nd Kompogas plant.
HZI is supplying the heart of the plant, a Kompogas plug-flow digester with a capacity of 1,500 m3, for the anaerobic digestion (AD) of 15,000 t/a of separately collected organic waste. This will produce around 1.5 million Nm3/a of biogas from fermented biomass. The gas will be fed to two downstream cogeneration plants with a total installed capacity of 1 MWel, while the heat produced will be used by the adjacent composting unit. Approximately 3.5 GWh of electricity will be generated from the processed organic waste, a renewable natural resource. This covers the energy consumption of 1100 German households. “Our Kompogas technology is already being employed successfully in more than 90 plants around the world, generating renewable and environmentally friendly biogas from organic waste. We are proud to have this opportunity to make a further contribution towards Germany’s efforts to achieve its ambitious climate goals with this 22nd Kompogas plant,” explains Dr. Helen Gablinger, Head of AD Sales at HZI. Construction of the plant is planned to begin in May 2019, and the plant will go into operation at the start of 2020.
