Key aspects of implementing the concept of closed-loop economy in the construction industry

Abstract

The paper considers the environmental situation in the country and the implementation of the concept of a closed-loop economy in the construction sector. The focus is on the sustainable use of resources, waste minimization and the use of secondary materials. The main types and volumes of world waste that have the greatest impact on the environment are presented, and it is noted that the construction sector occupies a leading position in terms of annual volumes, which proves the relevance of this study. The closed-loop economy helps to rethink existing approaches to the design, construction and operation of real estate. The paper presents key aspects of the approach to the formation of a closed-loop economy at various stages of the implementation of an investment and construction project, such as planning and design, preparation for construction, construction, operation and end of the life cycle. Particular attention is paid to the use of recyclable and environmentally friendly materials, as well as well as the application of technologies that make it possible to reuse construction waste. The paper also considers examples of successful practices and innovative approaches used in Russian and international projects aimed at increasing sustainability and reducing the environmental burden. Examples of the implementation of closed-loop economy projects in Russia, such as eco-industrial parks, which include a new approach to the implementation of recycling and waste disposal, are considered. The problems that the construction industry faces during implementation are emphasized, the main ones being the lack of a legal framework, the creation of incentive programmes for stimulation and the need to improve the skills of personnel. In conclusion, the importance of the closed-loop economy programme and the effectiveness of its implementation are highlighted.
