Comparison of options and optimization of sorting and collection of waste at demolition sites during renovation

The most famous and relevant innovative type of construction reorganization of urban areas is renovation that is defined in the directive documents of the Moscow Government as the demolition and dismantling of buildings in conditionally autonomous urban areas, defined by the well-known Resolution of the Moscow Government and legal documents explaining it, without taking into account the degree of physical or moral aging of these buildings and structures with the aim of erecting multi-storey residential buildings with increased comfort living in these territories. Thus, a certain meaning of renovation makes it possible and necessary to purposefully study and model the life cycle of this socio-technical and organizational-technological construction process, which has certain formal differences from the well-known model of the traditional life cycle of a construction facility and the sequence of stages in the implementation of this life cycle. The difference in the configuration of the life cycle of a construction facility in the traditional approach and in the innovative one in the conditions of renovation has been determined. In the study, this difference highlights the stage of demolition and dismantling, with which the problem of disposal of construction waste is inextricably linked. In this regard, an urgent task of comparing options and optimization of sorting and collection of waste at demolition and dismantling facilities at the first stage of renovationarises. Three options for solving this problem and projects for the production of work have been developed for each of the three options for the demolition and dismantling of buildings. The most rational is the second option
