State-of-the-art of Production and Utilization of Biogas in Germany

Biogas can be generated out of a variety of organic substances and is suitable for different utilizations. It is very efficient in technical application and has a good balance between energy input and output (1 : 7). Moreover there is a great reduction of carbon dioxide (6 - 7 t $CO_2$/ ha). By means of biogas energy can be produced locally and allows maximum energy utilization. Therefore in the next years biogas will become more important in Germany, also for the scientific research area. In the future we have to deal with questions about the improvement of efficiency of the biogas process intensified.
