Anröchte, GER

Kanadevia Inova is supplying the heart of the plant in Anröchte, a Kompogas® plug-flow digester with a capacity of 1,500 m³, for the anaerobic digestion of 15,000 t/a of separately collected organic waste. The 1.5 million Nm³/a of biogas produced annually is used to generate around 3.5 GWh of electricity in two downstream cogeneration units – covering the energy needs of 1,100 German households. The plant is designed to generate electricity according to demand. Thanks to interim storage zones for digestate and biogas, plus two different-sized cogeneration units, electricity can be generated and fed into the grid to coincide with daily peaks in demand.
