“…The systematization of considered research on C&DW flow management shows its relevance due to the need for waste management, resource saving in the construction industry, its use as secondary raw materials, as well as environmental protection. However, most scientific studies [5][6][7][8][9] are aimed only at adjusting the policy of resource saving of construction companies while the issues of sustainable development of the industry through the re-inclusion in the economic cycle of C&DW are quite fragmented. Thus, paper [10] tackles the effective management of C&DW as a condition for minimizing the harmful effects on the environment, as well as factors that hinder its implementation [11].…”

“…Thus, solving issues related to effective C&DW flow management should begin with the optimization of transportation costs, and therefore logistics costs, since their share in the total cost of C&DW flow management costs is constantly growing every day. This is due to the inevitable increase in obsolete houses (the service life of which is exhausted in the near future and the reconstruction of which is impractical), the significant remoteness of the infrastructure for their processing from the sources of formation, the complex routing of specialized vehicles by city streets and highways with limited traffic [5]. Instead, it should be remembered that waste flow management is carried out under the conditions of uncertainty, which is due, in particular, to the emergence of information risks, the consequences of which are undoubtedly losses, and, accordingly, a decrease in the efficiency of C&DW flow management.…”

This paper argues that in the context of transformation from the linear to circular model of the economy, the issues of managing the flow of construction and demolition waste (C&DW) are becoming increasingly relevant, which is primarily due to the increase in prices for building materials, as well as resource saving and interest of stakeholders in the creation of eco-cities. The tools and methods to manage C&DW flows have been examined in the context of simultaneous ensuring the environmental and economic efficiency of the process. It is substantiated that the expediency of implementing the C&DW flow management process exists only within the framework of the system of integrated management of waste flows from construction and demolition of real estate in compliance with logistical principles and coverage of the interests of all stakeholders of the process. Tools, methods to forecast and plan C&DW volumes within IFMS have been proposed, which contributed to the construction of a model for forecasting the volume of C&DW formation and, therefore, determining the amount of total costs for the creation of appropriate technological capacities; the development of a model for assessing information risks in the process of logistics management of C&DW flows (based on solving the transport problem according to Kolmogorov's differentiated equations) and constructing an algorithm for its application, the introduction of which in practice will ensure the balancing of the interests of each stakeholder interested in the processing of C&DW; solving the problem of synthesis of reducing the cost of managing C&DW flows and reducing environmental pressure. In order to combine the goals of minimizing costs and minimizing environmental damage within the framework of SIWFM, a two-purpose dynamic optimization model is proposed, as well as restrictions on the possibility of its introduction and validation of this study's results. It is substantiated that the tools and methods of economic and mathematical modeling proposed in the current study could solve an important scientific and practical task to effectively manage C&DW flows

Purpose. The main purpose of the work is to define and substantiate the principles, functional requirements and objectives of the implementation of information and analytical support for the management of waste streams of construction and wracking as secondary resources; development of the organizational and functional structure of the information-analytical management system, which would satisfy the conditions for the introduction of a logistical approach within the framework of integrated management of construction waste streams and became the basis for creating a single information platform. Methodology. As a methodological basis for the research of the process of managing the secondary resources streams and reversible streams in the construction industry, a logistic approach is used. It involves the analysis of factors influencing the system and study of its dynamic behavior as a complex adaptive system. The system approach in the development of information-analytical management systems involves solving the following tasks: development of a functional model of the management system of construction and wracking waste streams; construction of interaction matrices of automated processes and data routing processes; modeling the logical architecture of the data warehouses; development of a software and hardware set. Findings. The main tasks of developing information support for the logistics management system of construction and wracking waste streams are substantiated. The integration into the system of the following functional blocks is proposed: database formation; block for estimating the total economic costs of the process; environmental damage assessment blocks; information risk assessment; evaluation of alternative methods of waste stream management; optimal route formation block; visualization block. Based on the generalization of requirements and possibilities of the functionality analyzed information-analytical systems and requirements which would provide efficiency of construction waste streams management, the organizational-functional structure of the system of information-analytical management is proposed. Originality. The work gives reasons for the inclusion in the list of functional blocks of the organizational and functional structure of the information-analytical management system, which should be the basis for creating an information platform for the management of construction and wracking waste streams, environmental and information risk assessment. Practical value. Implementation within the information-analytical management of environmental damage assessment (as part of the efficiency assessment of the construction waste streams) and information risk assessment (as a tool of logistical approach) will provide the ability to predict key system indicators, make optimal decisions aimed at maximum inclusion of construction waste streams in the system as a potential secondary raw material, a sufficient level of economic and environmental efficiency with the optimal level of logistics costs.

Purpose. This paper aims to analyze and classify construction and demolition waste. It is necessary that this classification not only reflects statistical data on waste generation, but also serves as an information basis for the integrated waste management system (IWMS). The main task of this system is to maximize the involvement of waste in economic recycling and to objectively reflect the technological capabilities of its processing. This is extremely important in the context of the implementation of European waste management principles and the implementation of the National Waste Management Strategy in Ukraine until 2030. Methodology. The article considers the problems of construction waste management within the framework of the National Waste Management Strategy in Ukraine until 2030, which provides for the implementation of measures and principles of waste management, including construction waste. The author analyzes the management problems in the field of construction and demolition waste, which substantiates the need to classify construction waste with the simultaneous harmonization of processing methods and technologies. Construction activities are inextricably linked to the management of various types of resources, among which secondary materials play a key role in the implementation of construction processes. The ability to effectively manage the flows of these secondary resources is critical to ensuring the sustainability and efficiency of construction production. In this context, the study of the importance of managing the flows of secondary resources becomes an integral part of strategies for optimizing construction processes. Findings. Construction waste from the demolition of buildings and structures is unique due to its size and the need to prepare it for primary crushing. This is especially true in the context of implementing the concept of renovation of the outdated housing stock. Various static and dynamic methods of destruction of building materials, in particular, impact and vibration, have been investigated, with dynamic methods being characterized by lower energy consumption. Originality. The work reflects the formation of theoretical and methodological directions based on the use of recycled materials in construction, as well as a comparative characterization of various methods of destruction of building materials. Practical value. The possibilities of recycling construction waste, in particular, their maximum involvement in recycling, which meets the goals of the Strategy of Ukraine, provides 50% of waste recycling.
