As a result of the operation of thermal power plants used solid hydrocarbon fuel, ash and slag waste (ASW) is formed. ASW is a finely dispersed mineral material remaining as a result of burning brown and hard coal. The involvement of ASW in industrial turnover is one of the most effective ways to solve the issue of energy and resource conservation. The share of involvement of these types of waste in economic turnover in the European Union is about 98%, in China about 80%, and in Russia this indicator does not exce...

Solutions to the environmental problems associated with the burning of coal in power plants are in poor condition. One of the main problems is the continuous growth and accumulation of ash and slag waste (ASW). Ash and slag waste is a major source of raw materials for various industries. However, the degree of use of ash and slag waste at Russian thermal power plants does not exceed 2 million tons / year, with an annual output of 25-28 million tons. Modern methods of enrichment and processing allow the use of ash ...

In the current work, the process of fermentative conversion of animal waste and non-hydrolized plant materials (peat) using food waste and ascorbic acid salts as a stimulants is described. The amino acid composition of the biofermentation products was estimated. The possibility of the target biosynthesis for the production of fertilizers and feed additives with the pre-determined properties was recognized. It was shown that the additive of bread making waste with the concentration of 10 wt. % increases the amino a...

In the article synthesis of structures of disperse systems on the basis of gypsum is considered. Such systems are necessary for receiving materials which exclude burning of raw materials on the basis of gypsum waste for the receiving binders. For them use a certain composition of raw mix. Selection of structure of compositions allows to increase properties of materials. Such materials are characterized by high strength. The process of formation of structure of a gypsum which is received by hyper pressing is studie...
