utilization

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.

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

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.

It was considered the question of accumulation and reuse of construction waste. It was proposed methods of recycling construction waste into building materials.

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 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.
