Factors reducing the use of ash and slag materials
1.The lack in the country of a technical policy and the system approach at the decision of the specified problem;
2.The lack of economic interest of power stations to recycle ash and slag materials. As the main task of power stations is the generation of heat and electricity. In addition, all costs of transportation, warehousing and storage of ash and slag materials are included in the production cost price and are paid by energy consumers, and real economic incentives to reduce such costs are absent;
3.Decrease of profitability of the use of cheap raw materials (ash and slag) of thermal power by industry of construction materials, due to a sharp increase in the cost of rail and road transportation ;
4.The lack of legislative and regulatory frameworks sufficient to economic incentives to increase the use of ash and slag materials;
