Optimization and further development of the MAXIFuels concept

The main objective of the Maxifuel-III project has been to reduce the costs of production of 2nd generation bioethanol. To meet this objective, a number of projects, each investigating details of the individual process steps, have been carried through. Fiber and stems of maize have been tested as raw materials and suitable procedures have been established which secure efficient exploitation of these. Furthermore, alternative systems to produce cellulose-degrading enzymes through infection ofthe biomass with micro organisms have been studied. The results of these investigations cannot yet confirm as to whether this strategy will fulfill its objective. Significant resources have been applied to investigate the suitability of a wide variety of process equipment such as centrifuges and filters in the context of the MaxiFuel process. This activity has secured clear recommendations that can contribute to improved flexibility and energy efficiency. In summary, this series of investigations will contribute to the reduction of the costs producing 2nd generation bioethanol which was the purpose of the project
