STATE AND PROSPECTS OF HANDLING GLASS WASTE (REVIEW)

Abstract

The basic data on the volume of world production of glass and glass products are presented. The ways of handling glass products that have lost their consumer properties are analyzed. The difference between glass waste and other solid waste is shown from the point of view of the possibility of their repeated recycling without loss of operational properties, as well as extremely slow decomposition in natural conditions. The main methods of handling glass waste are considered and a critical analysis of each of them is given. Particular attention is paid to the methods of recycling and disposal of glass waste, which make it possible to effectively use recycled glass raw materials directly for their intended purpose with their inherent operational properties. The use of glass waste in the composition of building materials and products is promising: concrete, asphalt, bricks, tiles, heat and sound insulation materials and products. However, before organizing the production of the corresponding products, thorough research should be carried out, primarily from the point of view of the effect on glass-containing materials and products of an alkaline-silica reaction (ASR), which can lead to cracking and premature destruction of the corresponding product. The main ways of solving the problem of glass waste are proposed. Bibl. 77, Fig. 1, Tab. 1.
