Abstract:
The energy policy relevant to ecological aspects in all EU members since couple of years is determined by renewable energy sources (RES) development. Specific activities related to the increase of the share of RES in national energy like certificates of origin, penalties and fees all together make up a kind of enforcement that would encourage society to searching new possibilities to generate energy in accordance to respect to the natural environment. Seeking alternatives to fossil energy sources is the best option to force the approaching energy crisis. The paper aimed at analysis of possibility in using the digestate coming from biogas plant which cooperating with wastewater treatment. In details, some aspects of underestimated energy potential of digestate was developed as well as energy flow in analysed technological solution to demonstrate that it is possible to close this balance circle. As a result of the undertaken considerations there are some suggestions how to adopt the treatment system to improve effectiveness of waste management in accordance with energy production.
