WASTE MANAGEMENT PROBLEMS IN THE TERNOPIL REGION

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.

WOOD WASTES UTILIZATION OF THE POKUTSKO-BUKOVINIAN CARPATHIANS IN THE RESULT OF INTRODUCTION OF IMPROVED PRODUCTION TECHNOLOGY OF FUEL BRIQUETTES

In the article the estimation was conducted of ecological danger from the uncontrolled accumulation of arboreal wastes in the region of Pokutsko – Bukovinian Carpathians. The optimum terms of drying of wood wastes have been studied in an immobile layer. The optimum conditions are set of getting of fuel brequettes from wood wastes by the pressing method. As relating component  lignincontaining industrial wastes are used. The principal technological scheme  is offered of fuel granules production from wood wastes by the pressing method.

INVESTIGATION OF THE METHOD OF CHEMICAL DESORPTION FOR EXTRACTION OF NIKEL IONS (II) FROM BENTONITE CLAYS

The problem of accumulation of spent sorbents is considered in the article; The main methods of desorption of pollutants and regeneration of sorbents are described; the effectiveness of the method of chemical desorption for extracting Nikel ions (II) from bentonite clays is investigated; the main ways of utilization of spent sorbents are considered

Енергетичне використання осадів стічних вод у цементній промисловості

The paper presents the results of sewage sludge and carbon mud waste analysis. The conception of complex thermal utilization of sewage sludge and carbon mud was shown. On the basis of our study a granulated alternative fuel was created. Alternative fuels from sewage sludge co-processing help to reduce the usage of natural fuels in the cement industry and decrease the amount of unused waste.

Утилізація систем на основі концентрованої нітратної кислоти, яка містить сполуки йоду

The technological scheme of reprocessing the systems on the basis of concentrated nitrate acid containing compounds of iodine is presented. The offered scheme allows to reach the degree of utilization that exceeds 99 %. Наведено принципову технологічну схему переробки систем на основі концентрованої нітратної кислоти, яка містить сполуки йоду. Схема, що пропонується, дає змогу досягнути ступеня утилізації, що перевищує 99 %. 

The Utilization of Asphalt-Resin-Paraffin Deposits as a Component of Raw Material for Visbreaking

The paper contains the results of experimental study of visbreaking process with the use of organic part of asphalt-resin-paraffin deposits (ARPD) as a raw material component. We studied the influence of ARPD amount as the additive to tar on the output fuel fractions and their qualitative parameters. The proposals on modernization of the industrial visbreaking scheme with blended raw material were made. The analysis of economic performance of the modernized process was carried out.
