13 Project Pomeranian Biogas Model POM-BIOGAS POM-BIOGAS is a collaborative project funded by Norway Grants within the framework of the Polish-Norwegian Research Programme, operated by the National Centre for Research and Development. The project objective is to provide innovative technological solutions for production and utilization of biogas generated from municipal and selected industrial organic wastes and, in the context of the European Parliament Directive on waste 2008/98 EC, to increase the use of green energy instead of fossil fuels energy sources.

14 Objectives and tasks are included in five Work Packages (WPs) Mapping and optimisation of substrate composition aimed at enhancement of biogas recovery [WP1 Substrates], Enhancing biogas production using pilot tests [WP2 Process], Improving energy use of biogas [WP3 Biogas use], Assessment of the agricultural potential of digestate [WP4 Digestate use], Promotion and dissemination of project results [WP5 Dissemination & Management]

The value of P 2 O 5 in the annual output with ash from incinerators in Dębogórze amounts to zł. It is very desirable to process the ash towards phosphorous fertilizers.

26 Final Comment The goal of our research is to point out the areas which, through strategically focused R&D, will allow GUT to become an important participant in the discovery and production process, far beyond seeing Poland as municipal and industrial sludge resource owner and operation labor supplier.
