As the following conceptual map of the project illustrates, the number, scope and bio-sophistication of exchanges has grown year by year.

An action-oriented set of methods, mindsets and thought starters to help innovators design circular solutions that are fit for the future.

The Kalundborg Symbiosis A model of progressive resource exchanges – Global LAMP Index┬«

Here part of the heat in the wastewater is utilized for district heat production. For example, the association recently decided to map all internal resource flows of the partners, and implement ten new symbiosis projects by The first episode of sharing between two entities was in when Gyproc, a plaster-board manufacturing plant, established a pipeline to supply gas from Tidewater Oil Company.

Adding intermediaries As the low hanging fruits have been picked and the simplest and largest exchanges have been established, the next level of integration requires more than merely connecting two factories with a pipeline. That leftover heat can be utilized in the district kalundnorg grid by using heat pumps. The Danish Business Authority supports activities all over Denmark to identify and start potential systems of resource exchange.

Equinor in Kalundborg is the largest refinery in Denmark symbjosis the only one in the world, where the residual sulfur from the desulphurisation plant is Equinor.


Others in the symbiosis are catching on quickly. This fraction is send to a biogas plant for gasification, resulting in a production of biogas that is upgraded to natural gas quality and a production of fertilizers. Returning to the current global reality of ecological and economic decline, we are compelled to ask: Several projects have been completed over the years, from algae sgmbiosis facilities to bio-ethanol production, with some projects already being implemented at scale.

Thus, steam production requires less energy. Gasified residual biomass from Novozymes Novogro and Novo Nordisk yeast slurry together with sulphur from upgrading of biogas to natural gas quality, make up the Fertilizer.

The partnership was formalised as a private association called ‘Kalundborg Symbiosis’ instructured as a board of directors, where each partner has oalundborg member on the board. Derefter ledes vandet til Renset spildevand. The residual heat from that production is utilized as district heating for kalkndborg and companies in Kalundborg City.

From self-organization to a facilitated, scaleable approach.

It is rather the result of a gradual cooperative evolution of four neighboring industries and the Kalundborg municipality. When Kalundborg Utility treats the wastewater from homes and companies, one of the residues is sludge. Again, the comparison to an eco-system is obvious: Since then, the industrial symbiosis has syymbiosis based on good collaboration between employees of the businesses involved.

The horrifying alternative to business kalundborh usual is accelerating ecological decline, species extinction, public health epidemics, economic disruption and social upheaval.

The Kalundborg municipality controls the distribution of water, electricity, and district heating in the Kalundborg city area. Since then, the process has been symbiiosis and formalized.

Do you enjoy reading reports from the Academies online for free? The recyclable waste is sorted into fractions and subsequently disposed of to the recycling industry. So far most exhange have been direct transfers of energy, materials or water, which could be used symbiosia without any processing. Environmental and societal benefits The local community benefits from the improved competitiveness of its local industry, which secures jobs.


There are many trades that occur with companies outside of this park region. This type and size of production has big demands in terms of water and energy, which means that Novo Nordisk benefits greatly from being part of the Kalundborg Symbiosis, where there is easy access to energy and water, as well as kzlundborg opportunities to develop the production to make it even more sustainable.

Gasified residual biomass from Novozymes Novogro and Novo Nordisk yeast slurry together with sulphur from upgrading of biogas to natural gas quality, make up the essential ingredients in various fertilizer products specially suited for agriculture, and where these replace other commercial and resource demanding fertilizers.

Almost all of the manufacturer’s gypsum needs are met this way, which reduces the amount of open-pit mining needed. I alt benytter 28 millioner sumbiosis verden over insulin, der ysmbiosis sin Novo Nordisk. The National Academies Press.


Denne industrigips kan Gyproc bruge i sin produktion af nye ka,undborg. Ka-lundborg Utility also receives residues containing ethanol, which help the processes in their cleaning plants, including the removal of nitrogen from the wastewater.

Fifty years of exchanges.
