Full-scale biogas plant in Kalundborg ensures the return of all nutrients back to nature

At Bigadan’s Kalundborg Bioenergy plant in Denmark, AC drives from Danfoss help convert biomass from insulin and enzyme production to energy.

Biogas generated from pharmaceutical and other organic waste is purified to the same quality as the natural gas and is therefore suitable for distribution in the Danish natural gas grid. The pure biogas is an important CO2-neutral energy source that can be used directly for fueling city buses and in power plants to produce electricity and district heating.

“This is a good example of sector coupling, where all energy forms in the future will be linked together, such that society can use the least expensive and most environmentally friendly energy sources at all times”, explains Erik Lundsgaard, Production Manager, Bigadan.
