Kalundborg Fjord, located on the western coast of Zealand, Denmark, is a picturesque inlet that seamlessly blends natural beauty with industrial innovation. The city of Kalundborg, situated along the fjord, is renowned for its medieval architecture, including the five-spired Church of Our Lady, and its significant role in Denmark’s industrial landscape.

A notable feature of Kalundborg is the Kalundborg Symbiosis, a pioneering industrial ecosystem where public and private enterprises collaborate to utilize each other’s by-products, thereby minimizing waste and enhancing resource efficiency. Established in 1972, this symbiosis is a prime example of circular economy principles in action.
