DONG Energy's new biofuel plant in Kalundborg, Denmark, produces second generation bioethanol. Ramboll has played an important role in the construction of the plant. The advanced 3D modelling in particular has been crucial for finishing the project ahead of the COP15 conference.

The bioethanol at DONG Energy´s new Inbicon-plant is produced by using excess straw from Danish agricultural activities. The straw is fed into one end of the system where it is prepared, made fluid, fermented, and then distilled as bioethanol. The bioethanol is used in cars as a supplement to traditional fuels. The bio fuel is therefore part of the solution in reducing the carbon emission in the transport sector.

Reduced construction period due to 3D modelling 

With the opening of the Inbicon plant, the world's largest, Denmark is a leading nation within second generation bioethanol. The plant itself consists of a receiving facility for straw, a processing facility, an administrative building, a distillation tower as well as a tank farm. To keep track of the many pipes within the system, Ramboll has used advanced 3D models. This resulted in a greatly reduced construction time - without using these 3D models the projects would have taken at least an extra 6 months to complete. 

Straw becomes 5.4 million litres of bioethanol

The Inbicon plant uses four tons of straw an hour and will produce 5.4 million litres of biofuel annually. The processing of the straw results in two residual products - one is lignin, which can be used as a combustible for coal-fired power plants, and the other is C5 Melasse.  This can be used as animal feed, as well in the production of biogas.  The biofuel plant is located next to the Asnæsværket in Kalundborg, Denmark.
