MINING WASTE USING AS AN ALTERNATIVE RAW MATERIAL IN CONSTRUCTION

Abstract

Rapid industrial development and significant amounts of waste generated over the past decades have increased the need to combine economic growth with sustainable development and environmental protection. Over the past ten years, the share of industrial waste utilization was 27-34%. The high level of waste generation and low indicators of its reuse have led to the fact that significant volumes of solid waste are accumulated in Ukraine every year. This is a huge resource stock in terms of its scale. Over the past century, the extraction of ore materials and mining and chemical raw materials has increased 27 times, the extraction of minerals for construction needs – 34 times, while the amount of biomass production has increased only 3.4 times. An increase in the demand for minerals means an increase in the development and exploitation of reserves, as well as an increase in the rate of mineral depletion in various regions. The mining industry plays a strategic role as a supplier for the rest of the industries of many basic types of raw materials for modern society. The greatest commercial and economic interest is represented by decorative rocks, which, thanks to their aesthetic, physical, mechanical and polishing characteristics, are the raw materials that gave impetus to the development of the so-called natural stone industry. In this context, at the national level, the decorative stone sector mainly consists of limestone, marble, granite and other rocks (sandstone, quartzite, etc.). When regulating mining waste management, it is necessary to proceed from the principles of the concept of sustainable development, i.e. the need to establish a balance between meeting the current economic needs of the country and its citizens and protecting the interests of future generations, including their need for a safe and healthy environment. On the basis of the conducted research, it can be stated that the reuse of waste generated during the development of quarries makes it possible to: change the comprehensive approach to production processes; reduce the need for extraction, enrichment and processing of raw materials, which leads to environmental pollution; reduce overall construction costs; create a new alternative building material.
