Abstract. With the increase in the rate of civil construction and the growth of socio-economic development, there is a significant increase in the consumption of construction materials based on natural raw materials, which makes research in the search for an alternative raw material base for the construction industry as a whole relevant. Rational solution in terms of ecology and economy becomes the recycling of construction materials and the use of industrial waste. The trend of using construction waste as aggregates for concrete products and structures, is currently the most effective solution to reduce the negative impact on the environment, and also has a number of economic advantages, when choosing the optimal processing technology. This article considers the state, trends and problems of development of the construction sector of the economy in the direction of energy-efficient technologies and principles of sustainable development that help to reduce the negative impact of the construction sector on the environment in urban conditions. The main reasons for the increased interest in the research of environmentally friendly methods of recycling construction materials are indicated. The characteristics and unique properties of raw materials subjected to various methods of recycling are described. The advantages offered by the innovative system of «green» construction with the introduction of construction waste recycling technologies are given. The authors present an analysis of the most common technologies and methods of recycling concrete scrap into secondary aggregate, as well as the advantages and disadvantages of each method of regeneration of concrete scrap. The experience of researches of innovative methods of recycling concrete in foreign countries, the prospects and problems of further development of «green» technologies in the Russian building industry, and also priorities and prospects for entering the market of domestic producers of concrete products on the basis of secondary aggregate, which will allow to provide decrease in extraction and production of natural raw materials are revealed. Formulated further research directions of the problems of development of green technologies in the construction sector of the economy.
