Environmental impact assessment of chemical industry enterprises of the Republic of Belarus
Abstract
The paper presents an analysis of one of the largest branches of the industrial complex of the Republic of Belarus – the chemical industry on the example of an enterprise for the production of chemical fibers. The impact on the main environmental components of the enterprise for the period 2016–2020 is considered. It has been established that the enterprise belongs to category I of impact on atmospheric air. In total, 86 types of pollutants of hazard classes 1–4 are emitted into the atmospheric air, of which substances of classes 1 and 2 account for slightly less than 30 % of the total gross emissions of the enterprise. At the same time, an excess of the values of maximum ground-level concentrations was observed in 2020 only for ethyl acetate at the border of the sanitary protection zone. The paper also examines the dynamics of water consumption and the dynamics of wastewater generation at the enterprise. Despite the fact that during the period studied, the enterprise’s production capacity increased and the range of products expanded, the overall water consumption and wastewater generation decreased. The directions of treatment with production waste are presented. The waste generated as a result of production is sent for: processing at existing technological installations, for the purpose of further use in production; thermal neutralization in existing waste incinerators; disposal of solid municipal waste at the city landfill; implementation and storage.
