Sažetak

The article is devoted to resource-saving technologies that make it possible to switch to a business model of a cyclical economy in areas for applying PVC in spray booths with hydrofilters. The technology of saving resources is considered in detail: wastewater treatment of hydrofilters to the requirements of circulating water supply, as well as a scheme for the subsequent regeneration of sludge, as a secondary resource, to obtain additional products. The conditions under which sludge regeneration is more profitable than disposal are calculated and determined, and the areas of industrial application of the products obtained are proposed. Immanent assessment of the payback period of capital investments for the purchase of new equipment for the purpose of reusing resources. On the basis of the calculations performed, the authors prove the effectiveness of the proposed approach, which makes it possible to eliminate the costs of water consumption, wastewater disposal and sludge disposal and obtain the possibility of additional profit from the sale of the regenerated product. In conclusion, there is the inevitability of the transition of Russian industry to a cyclical economy, as a defining task for the development of society on the path of sustainable development and conservation of the natural environment.
