Abstract In the collective authors’ work, based on the analysis and generalizing of published scientific researches, regulatory and technical documentation and legal acts in the field of waste management and environmental protection, was undertaken an attempt to develop, on a single methodical basis, a set of consolidated resource-saving and environmental indicators characterized the process of prevention environmental hazard caused by anthropogenic influence of waste generated in construction and urban economy.The main purpose of the research is to form theoretical foundations, develop methods for a complex assessment of the environmental hazard of solid urban and construction waste, generated in the process of repair and construction, dismantling works, maintenance of the buildings, exploitation of engineering systems and technical means of buildings and urban services in the life support system of municipalities and regions, in order to ensure protection of the environment and humans from the anthropogenic influence of waste, creating favorable conditions for life of the humanity.In the research was realized scientific and practical tasks: was formulated a hierarchy of priorities for the state of environmental safety; was highlighted the main factors of the environmental hazard of waste of the economy; was developed a mathematical model for an integrated assessment, management (rationing, regulation) of the level of environmental hazard of waste; interconnection and consolidation of environmental and resource-saving indicators was carried out on a uniform information and analytical platform for a comprehensive assessment of environmentally safe waste management. The results of the research can be used in the investigation and engineering work related to the assessment of the anthropogenic impact of waste on the environment, planning measures to prevent it.

Treat Ment

In the article the estimation of ecological safety of schemes of handling was executed building wastes that are used presently. А comparative analysis is conducted with the perspective methods of handling wastes (recycling, incineration). Basic indicatos are set for the estimation of ecological safety of construction. The quantitative values of environmental indicators for each of the ways of waste management have been deter-mined. Results show that in terms of the Global Warming Potential, the most environmentally friendly treat-ment was recycling, followed by incineration and lastly landfilling.

Criteria For Evaluation

The formation and development of the waste processing industry is important in the social and economic life of society. Ensuring environmental safety, rational nature management and minimizing the negative impact of waste on the environment are priority areas for the development of the Voronezh region. Currently, the regional system for managing municipal solid waste is being modernized through the formation of inter-municipal environmental waste processing clusters (IEWC). In this regard, the need to study the issue of assessing the effectiveness of ongoing measures to form an integrated infrastructure for safe waste management is very relevant, especially in the context of digitalization. The analysis of the system of target indicators of the federal and regional levels for the disposal, disposal and disposal of waste. As a result of the study, it was concluded that environmental indicators prevail in the management system in the field of safe waste management. The team of authors examined the variety of properties and characteristics of socio-ecological clusters and, on the basis of a comparative analysis, highlighted criteria by which it is possible to assess the results of digital transformation and the efficiency of the functioning of the sphere of safe waste management in our region. Using the results of this study will make it possible to analyze and control the degree of achievement of the objectives of the regional program for the modernization of the waste management sector in order to make effective management decisions in the context of digital transformation.

Waste Management Practices

Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Building Information

At the present stage of the development of the construction industry, based on the principles of sustainable development, special attention should be paid to the formation of construction waste. Reserves for improving the level of efficiency of waste management can be found in the application of modern information technologies and their adaptation to resource-saving problems. The use of information systems is advisable at all stages of the life cycle of a building. Today, the technology of building information modeling (BIM) is actively developing, which can significantly reduce the amount of waste generation in construction. This is possible with its implementation at the design stage, in order to avoid irrational design decisions, collisions, etc. Information systems for data transmission allow rapid exchange of information between project participants, promptly warn about changes in space-planning decisions, materials, structures and equipment. At the stage of operation, in the presence of the information model of the building, it is possible to create a planning system for the organization of works of major overhaul or reconstruction. This article also proposes a description of the functions that an information system must have aimed at coordinating the management of construction waste in the region.

The construction industry consumes a substantial amount of raw materials in its processes and the output is obviously the product and most importantly the waste material. Other than that, the construction industry is well known as one of the worst environmental polluters. This study is to determine the use of waste minimisation technique in creating sustainable waste management in order to identify the technique which has the most capabilities to reduce on-site waste. The objective of this study is to assess the waste minimization techniques taken from the 4R concept (which includes reduce, reuse, recycle and recovery techniques) in minimizing the waste in construction waste management. The most used waste minimization technique found in the 4R concept would be waste reduction. This shows that the local construction industry has the knowledge necessary to plan out the waste management processes but the implementation is still far from satisfying. Additionally, the findings reveal that because the industry is profit-driven, construction practitioners are motivated by profit to adapt to this techniques.
