utilization

A low-temperature pyrolysis with pyrocondensate as a target product is one of the options for processing polyethylene waste. The fractional composition and properties of the pyrocondensate obtained at different temperatures and times were studied. Pyrocondensate was separated into gasoline, diesel fractions, and the residue. The composition and properties of mentioned fractions were established and related to the conditions of the pyrolysis process. X-ray fluorescence analysis of pyrocondensate and narrow fractions isolated from it was carried out.

One of the options for utilization of polyethylene waste is low-temperature pyrolysis, the target product of which is pyrocondensate. In the work, the fractional composition and properties of the pyrocondensate of pyrolysis of polyethylene waste were studied. It was established that pyrocondensate and its fractions practically do not contain heavy metals characteristic of oil fractions. Pyrocondensate is divided into gasoline, diesel fraction and residue. The composition and properties of these fractions were studied in detail.

Since slag and coal fly ash (CFA) are major global pollutants produced by thermal power plants (TPPs), special attention should be paid to their rational disposal. Scanning electron microscopy (SEM) was used to study the morphology of CFA and it was suggested that the use potential of CFA is high due to the presence of a large number of cenospheres (CSs), that can be recovered mostly by wet methods for the production of the wide range of products with improved properties.

One of the options for the disposal of worn car tires is low-temperature pyrolysis, the target product of which is pyrocondensate. The fractional composition and properties of pyrocondensate of pyrolysis of rubber waste obtained at an industrial plant are studied. The pyrocondensate was separated into gasoline and diesel fraction and residue. The composition and properties of these fractions have been studied in detail. X-ray fluorescence analysis and IR spectroscopic studies of pyrocondensate and narrow fractions isolated from it were performed. 

Today, in Ukraine, there is a problem with solid waste disposal, especially in small towns. The lack of a developed system for the collection and disposal of solid waste, the presence of natural landfills instead of equipped landfills lead to the fact that small towns are abandoned. Therefore, the creation of a new solid waste management policy is an acute problem for these towns and villages.

In Ukraine, along with the growing demand for tonnage production of light fillers, the need for raw materials is growing, considering that most of the range of light fillers is made from natural raw materials. Thus, a promising direction of utilization of TPP slags and coal concentrate obtained by enrichment of primary coal sludge is there involvement to the production process after preliminary drying.

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. 

The article is devoted to the study of reducing the technogenic load on the environment due to the integrated processing of household metal scrap. A waste-free, resource-saving, and environmentally safe method is proposed for extracting technical products from tin cans scrap - iron (III) oxide, tin (II) complex, suitable for further use, as well as fertilizer for agricultural crops. As a result of theoretical and experimental studies, the direction of cans scrap recycling was selected with an assessment of the parameters and factors affecting the reagent process of scrap disposal.

For the municipal solid waste (MSW) to be used in a proper way, it is necessary to implement clean technologies capable of thermal treatment of MSW and RDF in order to produce heat and electricity while meeting current ecological requirements. Nowadays, a number of technologies for MSW/RDF thermal treating are being used worldwide. Among them, the most proven technologies, applicable for industrial introduction, have been considered while analyzing their advantages/ disadvantages accounting for local conditions of Ukraine.

The National Strategy and the National Waste Management Plan in Ukraine until 2030, the regional
program for solid waste management in the Ternopil region for 2018-2020 on the reality of conducting key infrastructure measures and achieving the desired result for society are studied. An improved version of the solid waste management scheme in the Ternopil region and a suitable scheme for solid waste management in the city of Ternopil within the regional complexes for the municipal waste recovery are proposed and the sources of their financing are substantiated.
