The increasing connectivity in the world leads to the fact that the boundaries between internal and external security are blurring. Climate change and resource shortages combined with demographic growth and weak statehood can lead to conflict and instability around the world.
At the same time, transatlantic relations are changing. The task of improving European security lies primarily at European level, but there should be resources available. European countries together with the United States are responsible for peace and security in the world. In this regard, the two EU and NATO alliances will have to continue to carry out joint actions but should also be able to act autonomously if necessary on the use of global goods.

By asking the question of the creation of a single European army, we must say that the political will to integrate EU security and defense action is a primary factor. If Member States really want to guarantee the security of their citizens, to protect their humanitarian values in a global context, they have to have a huge political desire and not just “written documents”.

One of the most used types of biofuels is the biogas, produced during the process of anaerobic digestion of organic waste. The current project aims utilization of plant biomass waste, used to produce energy in the form of biogas, after proper pretreatment, in order to enhance energetic value and yield. Proper resource and method of pretreatment will be chosen, in order to obtain high biogas yields. The chosen technology will be tested in a plug-flow bioreactor to optimize the technical parameters.
