Nowadays, circular economy (CE) is on the agenda, however, this concept of closed supply chains originated in the 1960s. The current growing quantity of studies in this area accounts for different discourses except the holistic one, which mixes both approaches—contextual and operating (contextual approach utilizes the thorough examination of the CE theory, stricture of the policy, etc.; the operating one uses any kind of statistical data)—to assess the capacity of circular economy regulatory policy packages (CERPP) in operating raw materials and industrial wastes. This article demonstrates new guidelines for assessing the degree level of capacity (DLC) of CERPPs in the operation of raw materials and industrial wastes by utilizing the apparatus of the fuzzy set theory. It scrupulously surveys current CERPPs in three regions: the EU overall, Finland and Russia; and assesses for eight regions—the EU overall, Finland, Russia, China, Greece, France, the Netherlands and South Korea—the DLC of CERPPs in operating raw materials and industrial wastes. The results show that EU is the best in CE policy and its CERPP is 3R. The following are South Korea and China with the same type of CERPP. Finland, France and the Netherlands have worse results than EU with the type of CERPP called “integrated waste management” because of the absence of a waste hierarchy (reduce, recover, recycle). Russia closes the list with the type of CERPP “basic waste management”.

In this paper, the quality of the municipal waste sorting process in seven waste management centers in Slovenia was assessed using the qualitative multicriteria analysis (MCA) method DEX (Decision EXpert) implemented in DEXi software, which is based on multicriteria decomposition of the problem and utility functions in the form of “if–then” decision rules. The study was based on eight types of secondary raw materials. The quality of the secondary raw materials, the regularity of the delivery of secondary raw materials to recycling units based on the sorting efficiency, and the loading weight of the individual baled fractions in the transport of secondary raw materials for recycling were the main parameters used in the model. The final assessment shows “good” waste management service in centers A and D. Centers B, C, and F were rated “average”. The “bad” rating was assigned to centers E and G.

Comprehensive Processing

At present, the amounts of technogenic materials are constantly increasing. Therefore, the urgent tasks are the comprehensive processing and recycling of solid industrial and household wastes. In most cases, the process of grinding is one of the energy-intensive stages of technogenic materials processing. The possibility of manufacturing products from recycled wastes and the application area of secondary raw materials depend on the degree of grinding. Involving into technological use a large number of anisotropic and hard-processing materials requires the implementation of new types of shredders. One of them is needle-milling machines, the creation of which requires the development of both their designs and the calculation and designing methods which would take into account the physical-mechanical properties of the processed technogenic materials. For this purpose, a necessary set of studies was performed and their application was substantiated.

The article is dedicated to the research and development of intensive methods for curing products by capturing and binding CO2. It aims to improve and increase the productivity of technologies for the production of artificially carbonated building materials and products. Soda production wastes, limestone dust and finely dispersed limestone dust were used as the research objects. Secondary raw materials have been investigated using modern methods of phase composition and granulometry test. Intensive methods of production of accelerated carbonation of systems consisting of soda wastes were tested using multi-parameter optimization methods. The effects of recycled lime materials on the strength and hydrophysical properties of the obtained material were determined. The secondary raw materials effect depended on the composition of the raw mixture, molding conditions, CO2 concentration applied to the carbonate curing chamber, and the duration of exposure to environments with high CO2 content. It was found that the most effective way of providing accelerated carbonation curing of construction materials and products is a combined carbonation method, combining the principles of dynamic and static methods. It was concluded that the optimal CO2 concentration in the gas-air mixtures used for carbonate curing is 30%–40%.

The issues of application of the Territorial scheme of waste management in the Udmurt Republic and legal regulation in the field of municipal waste management from the position of forming a system of separate waste collection are considered. The main focus is on the regulatory and management mechanism for the application of the Territorial scheme from the point of view of the formation of waste processing infrastructure, their use as secondary raw materials and the introduction of waste separation collection. The article analyzes the experience of various countries in minimizing the anthropogenic impact of waste and introducing separate collection with the extraction of secondary raw materials using legal methods. There are "gaps" in the practice of developing and implementing a Territorial scheme as a resource for creating an administrative and legal field for separate waste collection and from the point of view of attracting the processor, as well as from the point of view of forming the ecological culture of the population. Conclusions are drawn and recommendations are made on the need to include in the points and sections of the scheme, on the example of the Udmurt Republic, mechanisms for implementing separate waste collection, forming an environmental culture of the population and attracting processors as active participants in the MSW management system.

In the horticultural industry, upon main products obtaining, the formation of the following secondary raw materials and production wastes: pulping,bagasse, tomato seeds, fruit seeds, vegetable peelings, etc. is concomitant. At the same time, the amount of secondary raw materials formed during fruit and vegetable raw materials processing  varies from 5 to 85% of the initial raw materials mass going for processing, of which an average of 30% is sent to food products for food processing. The aim of the work was to study the possibility of bagasse using of direct extraction beet juice production in vegetable paste technology. To facilitate the process of bagasse pulping, pretreated with microwave heating, starch syrup, allowing to reduce the vegetable mass viscosity was proposed to use. As a result of research, it was found that the introduction of starch syrup in the bagasse in the amount of 10, 20 and 30%, along with an increase in the heating temperature, varying from 25 to 60, reduces the effective viscosity obtained after bagasse paste pulping. With an increase in the starch syrup dosage, an increase in the mass fraction of dry substances in beet paste and its liquefaction degree was observed as well. So, at a dosage of 10%, the liquefaction degree was 24.7%, at 20% - 45.1%, at 30% - 60.7%. Thus, the use of starch syrup in the production of beet paste from the bagasse of direct-pressed juice production makes it possible to adjust the vegetable mass viscosity purposefully, creating better conditions for subsequent technological operations. .

Industrial Waste Treatment

One of the objectives of industrial waste management is to reduce the amount of waste and to ensure its reuse in a way that allows notable improvement of resource efficiency. Location of a waste treatment plant is a strategic issue that require careful logistics system planning. The aim of this article is to create a model for solving the locationallocation problem of waste (i..e. secondary raw materials) treatment facilities, taking into account the territorial distribution, the type, and the quantity of secondary raw materials, the distance between waste-generating industries, as well as the CO 2 emissions from transport of secondary raw materials. The basic principle for defining a mathematical model is minimization of CO emissions from transport-related activities; 2 for this reason, modeling is based on the p median model that has been modified and put within the context of industrial waste management, including CO emissions from 2 transport. The location model is based on common industrial waste streams and CO 2 emissions from vehicles commonly used to transport secondary raw materials from generators to facilities. The verification of the model was performed through a case study that included the region of southeast Serbia. It confirmed usefullness of the proposed model for deciding on optimal locations for new industrial waste treatment plants.
