The complication of the environmental situation in the world makes mankind look for new economic models in which sustainable development is provided. With the growing population of the planet and its needs, there is an overconsumption of natural resources. The factors that are formed as a result of polymorphism of the system components «economy»-«ecology»-«society» are considered. It is proposed to replace the linear economy model, implemented in particular in the construction industry, with a model of the circular economy with its main imperatives oriented to biosphere-compatible construction at all stages of product creation while preserving natural resources.Keywords: circular economy, recycling, functional transformation, natural capital, greening, object life cycle

A growing concern is given to the environmental impacts caused by the construction industry. Waste generation, resource consumption, and greenhouse gas emissions are the main drawbacks of the rapid urbanization that the world is witnessing. As a response to these pressing issues, policymakers and academia are exploring the concept of Circular Economy (CE) to manage resources better and achieve resource efficiency while eliminating waste. One of the strategies to implement CE in the built environment is to select the appropriate building materials and components from the early stages to carry out the concept's principles along the value chain and create a closed-loop system. Therefore, this study aims at identifying selection criteria for building elements according to CE principles through a review of the latest research. Results have shown that little has been concretely achieved in terms of a paradigm shift to CE since the main focus of the literature is still the use of recycled products and the recyclability of building materials and components at their end-of-life. Although the present study is solely focused on the technical aspect of building materials and components, it outlines current adopted criteria to bring about a circular built environment and highlights the need for a more innovative approach to attain higher circularity levels.

The article discusses the basic principles of the implementation of the transition from a linear economy to a circular economy model. The article summarizes the existing problems that require solutions to create new jobs, increase economic growth, and create a balance between the economy, environment and population. The authors present examples of building a circular economy model in foreign countries. The importance of the tasks of implementing and promoting the circular economy was revealed, thanks to the involvement of all participants in the society in this process and the motivation for companies and investors. Effective tools for moving society towards a resource-efficient closed-cycle economy, increasing energy efficiency, energy conservation and reducing the energy intensity of the gross domestic product, due to the entry into a competitive level of renewable energy sources are investigated. The introduction of digital technologies and artificial intelligence in automated accounting of resource consumption, as well as the improvement of accounting rules will create opportunities for the end user to manage resource consumption taking into account the principles of a circular economy. The authors' study emphasizes that circular economy products and services should minimize resource use and promote reuse, recovery and recycling of materials in the future, leveraging existing product policy instruments, further support for the repair sector, improved design for reuse, and high-quality packaging recycling. The authors in the article propose to legislate the subsidizing of enterprises participating in the circular chain and subsidizing innovative developments in the field of the circular economy in the Russian Federation.
