DONG Energy and Bigadan is to build a large-scale biogas plant that will reuse residues from the production facilities of Novozymes and Novo Nordisk in Kalundborg on Zealand. The four companies have just signed an agreement which, from spring 2018, will carry yet another significant contribution to the Danish production of green energy from biogas. The new biogas plant in Kalundborg will convert residues from the factories of Novozymes and Novo Nordisk in Kalundborg to bio natural gas which can be fed directly into the Danish natural gas grid.

Novozymes and Novo Nordisk, Danish big companies, have in collaboration installed a 36 meter tall, high-performance biogas reactor. The new biogas reactor utilizes wastewater from both Novo Nordisk and Novozymes’ large production in Kalundborg for an efficient production of biogas.
There are two specific reasons for Novozymes’ investment in the new biogas reactor. “Firstly, we can reduce CO2 emissions from our production. This enables us to reduce our CO2 emission with 21,000 tons annually, equivalent to emissions from 12,000 households or 1000 trucks each driving a 1000 kilometers,” explains Line Sandberg, Vice President in Novozymes’ Danish production.
