Abstract
The analysis of activity of stone-mining enterprises shows the low competitiveness of crushed stone products Upgrading the quality of crushed stone and production of the European standard fractions requires to use of new technologies and equipment. The main waste of crushed stone pits is сrushed granite waste, which high percent of an exit is caused by outdated equipment and incorrectly selected technological parameters of the crushing process. Crushed-granite waste is stored in dumps which occupy large areas and negatively effect on production area ecology. In November 2017, the Government of Ukraine accepted the National Waste Management Strategy until 2030, the main aim of it is develop a strategy of the mineral raw materials balanced use and international standards introduction at the national level. Therefore, the problem of complex utilization and recycling of waste from stone-mining enterprises with receiving a qualitative secondary product is relevant. The publication presents the сrushed granite waste volumes by crushed stone pit, its properties and main directions of utilization. The ecological influence of waste dumps, in particular granite dust, on the environment and human, the strategy of using non-waste technologies and ecological features of сrushed granite waste secondary processing are considered.
