The article is devoted to the study of the prospects of using compost with sewage sludge in the raw material for the recultivation of disturbed lands. A special installation was used for bio-composting, which allowed controlling of the process parameters. The results of bio-indication of composts obtained under different conditions of compositions of the raw material mixture are given. Based on the analysis of the results of bio-indication, the optimal composition of the raw material mixture using "fresh" and "old" sewage sludge is established.

As of today, the principle of zero-waste production is not only a global trend, but also an effective mechanism for protecting and preserving the environment, as well as making fuller use of the resource potential of enterprises. The main idea of zero-waste manufacturing is the transformation of raw materials received by the enterprise, its residues, as well as waste obtained in the production process, into finished products that can generate income.

Ukraine has significant land resources for agriculture and is able to provide its population not only with food but also with raw materials for bioenergy.

The article is devoted to obtaining a porous filler from the slag of the Thermal Power Plant and investigation of the filtration method for the drying of slag and clay as main raw materials for preparing the charge for porous filler production. 

A lot of factors from the domestic, national and international environment have a significant influence on the decision to initiate tolling cooperation and its continuation. In today’s hyperdynamic and extremely uncertain economic conditions it has been substantiated that correlation-regression modeling is the most effective tool for quantitative analysis of the factors influencing the enterprise's tolling operations.

The basic requirements for raw materials for obtaining strong alcoholic beverages were researched. The analysis of the raw material base of Ukraine for the production of grain distillates is made. As a result of the analysis of the raw material base of Ukraine, the presence of quality raw materials for the production of grain distillates was confirmed. The peculiarities and component composition of the obtained product depending on the method of process realization were investigated. The influence of distillation method and organoleptic characteristics of grain distillate were considered.

The article is devoted to the process of extraction of oil from rapeseed and sunflower seeds and meal by an extraction method based on the study of the kinetic regularities of the process.

The main methods of fuels for gas-turbine engines manufacturing are presented in the given article. Taking into account limitation of the world deposits of oil and other fossil fuels, the perspectives of various kinds of raw materials application for jet fuels production are discussed. Processes of raw materials extraction and processing, further manufacturing and use of jet fuels were analysed and their impact on environment was estimated.
