2016.05.26 Minister of Agriculture and Food, Jon Georg Dale, was again visiting the biorefinery laboratory. This time to announce that NMBU has got a new Center for Environment-friendly Energy Research, a so called FME (Forskningssenter for miljøvennlig Energy) Center. The Center is named Norwegian Centre for Sustainable Bio-based Fuels and Energy, and focus on production of 2nd generation biofuels. This is a huge Centre with around 50 partners and it will run for 8 years. The BTB group will particpate in the Centre. More information here (Norwegian)
