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.

SCOTLAND: In line with the zero-waste objectives of the Scottish government, treatment of non-recyclable urban waste contributes to eliminating landfill whilst generating electricity and heat. Equipped with high-efficiency VACON® NXP drives, the process generates heat enough to supply 25,000 households.

DENMARK: Taarnby Municipality within Greater Copenhagen is the first to integrate the production of district cooling and district heating in combination with ground source cooling and chilled water storage in one facility that also exploits surplus heat from a nearby wastewater treatment plant. This symbiosis allows the utility company to provide building owners in the district with competitive and environmentally friendly cooling – while generating more cost-effective heating to the district heating network.
