The publication analyses and evaluates the impact of the implementation of circular economy on the economy and especially on its mining and power generation sector in Poland. Circular economy is a relatively new concept concerning an innovative economic development model. The publication briefly describes the concept of circular economy. Among other things, the basic economic processes that make up circular economy are discussed. In addition, history is presented as well as examples of legislation that have had the strongest impact on the implementation of circular economy in the EU are identified. Further on in the paper, the impact that circular economy will have on the mining and power generation industry in Poland is discussed. Areas have been identified that will need the most attention in relation to the implementation of circular economy. It was pointed out that in the mining and power generation sector the scale of use of current and landfill waste should be increased as a priority. Attention has been paid to the necessary reduction of water demand and rational water and sewage management. Examples of use of mining gas and ventilation air have been discussed. The publication provides examples of a number of measures taken in accordance with circular economy. It was pointed out that there is still a need to popularize the existing ones and to look for new technical and organizational solutions conducive to the introduction of this new economic model. An important aspect of the impact of the circular economy on these sectors will be the decrease in energy demand resulting from the widespread implementation of the new economic model. For those already struggling with a number of problems of some of the mining and power generation sectors based on coal mining and combustion in Poland, the implementation of circular economy will pose another challenge.

The article concerns fly ashes generated from the combustion of hard coal and deposited on landfills. Investigation results describing fly ash taken from a combustion waste landfill are presented in the article. The investigation results indicate a possibility for combusting the coal reclaimed by separation from the fly ash and utilizing the remaining fly ash fractions.

Przedstawiono możliwości wykorzystania popiołów lotnych jako cennego surowca. Po modyfikacjach mogą one być wykorzystywane jako sorbenty zarówno w metodach suchego jak i mokrego odsiarczania spalin, jako surowiec do otrzymywania materiałów mezoporowatych oraz stanowić źródło cennego paliwa i składnik cementu.

EN

Possibility of fly ashes utilization as valuable materials was described. Modified (processed) fly ashes could be applied as sorbents in wet or dry methods of the flue gases desulphuration process as well as stuff in mezzo-porous materials production. It is possible to use fly ashes as concrete's compound and special fuels.

Zgodnie z ustawą o odpadach z dnia 27 kwietnia 2001 r. w 2002 r. opracowany został Krajowy Plan Gospodarki Odpadami. Unia Przedsiębiorstw ubocznych Produktów Spalania opracowała cząstkę planu, dotyczącą energetyki zawodowej. W opracowaniu przedstawiono: aktualny stan gospodarki odpadami w energetyce zawodowej; określenie potrzeb w gospodarce odpadami; prognozę gospodarki odpadami; założenia do planu; plan gospodarki odpadami; system monitoringu i realizacji zamierzonych celów. Zaplanowano: - 11 rodzajów przedsięwzięć techniczno-technologicznych (59 instalacji zagospodarowania ubocznych produktów spalania i 15 modernizacji instalacji istniejących), - 6 rodzajów przedsięwzięć organizacyjno - prawnych. Oszacowano efekty ekonomiczne i niewymierne, możliwe do osiągnięcia w wyniku realizacji planu. Cząstka planu opracowana przez Unię została uwzględniona w zatwierdzonym Krajowym Planie Gospodarki Odpadami.

The National Plan of Waste Management was prepared in 2002 in accordance with The Act on Wastes of April 27, 2001. The Union of Companies of Combustion By-Products developed a fragment of the plan related to public power industry. The paper presents: - current state of waste management in public power industry - specification of needs in waste management - prognosis of waste management - assumptions for the plan - waste management plan - system of monitoring and realisation of the set targets. The plans were prepared of: - 11 types of technical & technological measures (59 installations of combustion by-product management and 15 modernisation processes of the existing installations), - 6 types of legal & organisational measures. Economic effects and non-measurable benefits that can be achieved as a result of the plan realisation were estimated. The fragment of the plan prepared by the Union was included in the accepted National Plan of Waste Management.

The demands connected with supplying the society and economy with electrical energy and heat are mainlymet thanks to mining fuels combustion. The mains few are hard and brown coal. Even though its negative influence on the environment is constantly tried to be minimised, the process is still considerably burdensome. Apart from the pollutants released into the air and contaminating water, there are also coal combustion by products. Coal combustion by-products, depending on their properties which are influenced by the quality and kind of coal, by the technology of combustion as well as by addedsorbent, are used in industry, highway engineering and agriculture. However, this way of using by-products is not done on a grater scale. Placing the unused by-products in their original location, that is in the underground hard coal mines and open-cast brown coal mines as the reclamation of those headings could be a solution. Such action is especially justified in case of mining and power industry complexes where the transport of the combustion products is more convenient.
