Sustainable Resource Processing

Case Study: Kalundborg Industrial Ecology

Starting in 1972, a Danish industrial symbiosis has developed between five industries & the town with the result that resource wastage & pollution has been significantly reduced

•Waste heat from the power station goes to the town, Novo Nordisk & the fish farm

•Statoil by-product gas goes to Gyproc & the power station

•Water is exchanged between almost all the parties

•Sent out of the region are power station fly ash for cement & sulphur for gypsum production

•The energy efficiency of the Asnæs coal-fired has grown from 40% to 90%

•The industries are the Asnæs coal-fired power station, the Statoil Refinery, the Novo Nordisk pharmateutical plant, the Gyproc wall board factory and the Asnæs fish farms. The Kalundborg Kommune (township) is a major user of waste heat from the power station.

•Gyproc located in the region to use Statoil by-product gas

•All the materials exchanges have been bilaterally & voluntarily negotiated

•The exchanges were motivated initially to save money on waste, then to cut costs of pollution control.
