ISC Consulting Engineers has worked with DONG Energy to design a bio-ethanol plant in Kalundborg, Denmark. They have used software programs to design the piping and analyze the stress and flexibility of the pipes. The plant produces second generation bio-ethanol from agricultural and forestry remnants, and it also produces bio fuel and molasses. The plant was put into operation in December 2009. However, in 2014, DONG Energy decided to shut down the plant, and further testing was done in a pilot plant in Skærbæk. Both Inbicon and Terranol presented their results at a conference in 2015.
