Recycling of construction and demolition waste during renovation of territories and pavements of large cities

Abstract

In the process of urbanization of large cities in different countries, there are similar problems of reorganization, involving the demolition of physically and morally obsolete buildings and structures, as well as the subsequent construction reorganization of the territories vacated or re-cut to the city. In the process of demolition of obsolete buildings and structures, as well as the construction of new buildings, inevitably significant amounts of waste and construction debris arise that should be recycled as much as possible into secondary building materials (to carry out the so-called «recycling» of waste). Types of construction reorganization of urban areas are divided into traditional, widely known and standardized (repair, reconstruction, restoration), and innovative, arising in the processes of reorganization of society. Among the innovative types of construction reorganization, renovation is currently the most relevant, meeting the need to renovate the dilapidated housing stock of cities. The article discusses the main types of construction waste generated during demolition and new construction, as well as the technologies used for recycling these wastes during the renovation of territories and pavements of large cities.
