In a market economy, it becomes important to improve the organization of enterprise management and, above all, the production process, efficient use of financial, material resources and inventories. Effective management of material resources increases profits and provides the necessary investment. To maintain high profitability and liquidity, the management of current activities of enterprises, in particular inventory management plays a significant role. The categorical apparatus of material resources management at the enterprise is considered, the definition of “material resources” is generalized, the definition of "material resources management" is offered, and also the system of material resources management at the enterprise is considered. In the management of material resources at the enterprise there are 2 approaches – logistics and reengineering. The main tasks of the mechanism of management of material resources of the enterprise of building materials are defined. These are: increasing the efficiency of material resources and choosing cheap sources of funding; introduction of new production, resource-saving technologies; minimization of costs for procurement, production and marketing activities; increasing the interest of employees of all services in the effective performance of their duties; product quality management. The analysis of efficiency of use of material resources at the enterprises of building materials which has shown, that manufacture of production is rather material-intensive is carried out. This is evidenced by the share of material costs in the cost of work, and the value of the utilization factor of materials indicates the economical use of material resources in production. Reserves for improving the efficiency of material resources at construction materials enterprises have been identified. The ways of the most rational use of material resources of construction materials enterprises are offered, in particular it is improvement of a design and technology of manufacturing of products, introduction of more progressive norms of expenses of resources, use of substitute materials, and reduction of losses at stages of transportation, storage and industrial use.

AbstractCoefficient-based, bottom-up material flow analysis is a suitable tool to quantify inflows, outflows and stock dynamics of materials used by societies, and thus can deliver strategic knowledge needed to develop circular economy policies. Anthropogenic stocks and flows are mostly of bulk nonmetallic mineral materials related to the construction, operation and demolition of buildings and infrastructures. Consequently, it is important to be able to quantify circulating construction materials to help estimate the mass of secondary materials which can be recovered such as recycled aggregates (RA) for fresh concrete in new buildings. Yet as such bulk materials are high volume but of low unit value, they are generally produced and consumed within a region. Loops are thus bounded not only by qualitative and technical restrictions but also spatially to within regions. This paper presents a regionalized continuous MFA (C-MFA) approach taking account of these restrictions of local consumption, quality standards and technical limitations, illustrated using the example of Germany. Outflows and inflows of stocks are quantified at county level and generalized by regional type, considering demand and supply for recycled materials. Qualitative and technical potentials of recycling loops are operationalized by defining coefficients to reflect waste management technologies and engineering standards. Results show that 48% of outflows of concrete and bricks are suitable for high-quality recycling, while 52% of outflows do not fulfill the quality requirement and must be recovered or disposed of elsewhere. The achievable inflow to RA is limited by the building activity as well as the requirements of the construction industry, e.g. the RA fraction of fresh concrete must not exceed 32%. In addition, there exist spatial disparities in construction across the country. In Germany, such disparities mean that there will be a shortfall in RA of 6.3 Gt by the year 2020, while the technically available but unusable RA (due to a regional mismatch of potential supply and demand) will total 3.2 Gt. Comprehensive recycling strategies have to combine high-quality recycling with other lower-grade applications for secondary raw materials. Particularly in the case of building materials, essential constraints are not only technical but also local conditions of construction and demolition. These interrelations should be identified and integrated into a comprehensive system to manage the social metabolism of materials in support of circular economy policies.

An estimate of natural and technogenic raw material bases for construction materials production is given. These two groups of primary products are suggested to be considered as a united raw material base for building industry due to including industrial wastes. To be selected for an appropriate use every industrial waste sort must undergo several levels of estimation on the following criteria: toxic level; chemical and mineral composition; selection of wastes from ready-made construction materials or their components; selection of wastes from ready-made raw mixes for the production of building materials; estimation of aggregate state; estimation of the amount of formation. After such a multilevel estimation, waste is getting a certain status.

Gas Cleaning

High requirements to ensure sanitary and hygienic working conditions and reduce harmful emissions into the environment are provided through ventilation systems equipped with efficient and economical equipment. The task of improving the air basin is to reduce the amount of harmful substances in the ambient air to the level of MPC and lower, which, with increasing volumes of ventilation and process emissions, determines the increased requirements for industrial filters. The most effective are wet devices, in which the process of gas cleaning is carried out through interaction with the liquid, most often with water. The authors developed a number of high-efficiency dust-collecting apparatuses, in which the majority of methods for contacting elements with a liquid are realized simultaneously, which determines the maximum completeness of gas purification from dusts with different physico-chemical properties. One of them is an aerohydrocyclone intended for combined simultaneous cleaning of a technological product in the form of a suspension and dusty air removed from the shelters of technological equipment. This apparatus with internal circulation of liquid, where the concentration of trapped dust in the irrigating liquid affects the efficiency of dust collection, the frequency of water replacement, the operating mode and the load of the water-slurry farm. The particulate materials of the slurry intensifies the process of dispersion, irrigating liquid and its structural viscosity, as well as the stability of the formed foam, which contributes to a more effective manifestation of various wet dust collection mechanisms.The implementation of the installation of a wet dust collector for complex cleaning in the technological line for the preparation of lime milk from the construction materials factory made it possible to reduce the concentration of dust in emissions at the maximum level of ensuring the economy of aspiration systems. The obtained results testify to the positive experience of the operation of wet dust collectors for complex cleaning in the building materials industry, and the regularities connecting the operation modes of the apparatus with the properties of trapped dusts and the features of technological processes make it possible to recommend them for use in various enterprises.

The priority in improving the existing methods of processing fish is salting with the use of food additives with different functional orientations. The aim of the study was the development of preserves with the introduction of lactate-containing additives and using sonochemical technologies; examination of the quality of the products obtained according to organoleptic and microbiological safety indicators. The article proposes a resource-saving technology for the production of fish products with prolonged shelf life due to the use of a complex food additive consisting of lactic, acetic, propionic acids and their salts in different proportions with subsequent ultrasonic treatment using the ultrasonic generator of the Wave series model UZTA-0 2/22-OM. There was established the optimal mode of using the ultrasonic processing power of 75 W / m2 in the manufacture of fish preserves from herring. Organoleptic and microbiological quality indicators were studied during storage of preserved products with the addition of additives and ultrasonic treatment compared to the control. Organoleptic assessment was carried out on a five-point scale, microbiological indicators were studied by standard methods. The Dilactin Forte Plus dietary supplement in the composition of preserves in the amount of 3% and in combination with the use of sonochemical technologies makes it possible to obtain a safe high-quality fish product. Manufactured preserves at a storage temperature of 0 ± 2 ° C can maintain their high quality for 5 months.
