Abstract: Production and utilization of renewable energy sources are justified not only by
energy-political, but by environmental aspects too. It can be verified the necessity of the complex
ecological aspects by biogas production experiments and its utilization tests in gas engines
therefore we created a complex biogas production and utilization system, so that both the energy
and the environmental goals can be achieved together. In the interest of an optimal solution it is
necessary to analyze the two objective functions (the production and utilization functions)
together, considering that the principle of the complex optimization focuses just on the
environmental-friendly energy utilization. The centre of the system is the integrated wastemanagement. Its advantages are the local and global environmental results, energy production
independent of external influences, as well as a near optimum solution ecologically.
Keywords: complex system, energy production, waste-management
