The Kalundborg Utility is situated on the north-western coast of Zealand in the City and Municipality of Kalundborg. Due to a change in legislation, the company separated from the Kalundborg Municipality in 2009 to continue as a private limited company with all shares owned by the municipality. The company provides products and services including drinking water, processed water, wastewater treatment and district heating.
The utility shares a geography with a number of Danish and international industrial manufacturing companies. Some of these companies, together with the utility and the municipality, are partners in the Kalundborg Symbiosis, a closed-cycle industrial collaboration. Kalundborg Symbiosis has existed for more than forty years and is a system where one partner’s residuals become another partner’s resource.
