 The successful achievements in practical and efficient use of ash and slag waste from thermal power plants in a number of advanced foreign countries are well known and quite significant. The achievements of the Russian Federation in this respects are, on the contrary, extremely modest. Today, it has become obvious that no significant success can be achieved without the willed relevant decisions of supreme government bodies (legislative as well as executive) that would take into consideration the technical, economic, and processing features of the discussed problem.

At the same time, special attention should be paid to the necessity of improving the quality (consumer) and therefore marketable properties of the ash and slag materials. In such case, there probably will not be any more discussion about whether these materials are waste or by-products of thermal power plants.
