Value proposition

Surplus from circular production

The Kalundborg Symbiosis is a partnership between seventeen public and private companies in Kalundborg. Furthermore, we work closely together with project Biopro.
Since 1972 we have developed the World’s first industrial symbiosis with a circular approach to production. The main principle is that a residual flow in one company, becomes a resource in another, benefiting both the environment and the economy. Having a local partnership means that we can share and reuse resources, and that way we save money as well as minimize waste.

Currently, the symbiosis counts more than 30 individual streams between the partners:
- Novo Nordisk
- Novonesis
- Kalundborg Refinery
- Ørsted
- Saint-Gobain Gyproc
- Kalundborg Municipality
- Kalundborg Utility
- ARGO
- Avista Green
- Kalundborg Bioenergi
- Unibio
- Meliora Bio
- Boehringer Ingelheim
- COMET
- Intertek
- APM Terminals
- Schultz Shipping Group
The Kalundborg Symbiosis is a private association, that is led by a board of directors, a yearly general meeting and a manager employed by the board.
