Article presents the results of long-term testing of prototype of 64 kVA biogas cogeneration set (CHP - Combined Heat and Power), build with support of financial means from the MCP R&D program 1 2 1. Between others, the impact of fueling with biogas from the sewage treatment plant on the engine oil has been investigated. Used oil analyses unveiled adverse presence of silicon compounds, i.e. siloxanes, permissible level of which (according to MAN standard) was exceeded several times. In order to reduce these compounds, prototype biogas filter based on activated carbon has been developed. Based on initial calculations, overall efficiency of this cogeneration set is circa 70%. For the consumer needs, the entire installation is enclosed in a compact soundproof canopy. Besides environmental merits, the cogeneration set shows also economical advantages. If operating continuously, the gen-set CHP would produce electrical and heat power in an amount that its purchasing cost would be returned after about 12 months, under condition of having biogas.

The bottom waste obtained from bio-mass burning shows a huge variability of chemical and physical properties, depending on the kind of bio-mass, the type of a cauldron and burning parameters. The huge variability of the bottom ashes from the incineration plant and co-combustion of bio-mass makes it difficult to find any way to its management. In reality, only the bottom ashes from coal combustion and the small amount from lignite combustion are used, mainly in the building industry and in mining industry. The article presents the initial research, concerning the estimation of the properties of the bottom ashes obtained from bio-mass congestion in the fluidized-bed boiler to use them safely for the environment. To determine the influence of the tested waste on plants, a number of pot experiments have been conducted. The plants which have been used are recommended for phytotoxicity estimation, and are also used for biological reclamation.

W artykule przedstawiono najistotniejsze kwestie dotyczące stopniowego rozwoju wykorzystania OZE w Polsce, zarówno szanse intensyfikacji wdrażanie nowych technologii, ale też i ryzyko niewywiązania się z międzynarodowych zobowiązań Polski wobec UE. Rolnictwo dysponuje znacznym - dotychczas niewykorzystywanym potencjałem energetycznym, mogącym zasilać lokalnie gospodarstwa rolne lub w znacznym stopniu uzupełniać ich potrzeby energetyczne.

The article presents the most important issues concerning gradual development of RES in Poland, both the chances of intensifying the implementation of new technologies, but also the risk of failure to comply with international obligations of Poland towards the EU. Polish. The agriculture has a significant - previously unused energy potential that could supply local agricultural farms or substantially complement their energy needs.
