The relevance of the study consists in the problem of incompletely regulated legal relations in the field of emergency forecasting. This problem represents an important factor and condition for the unpredictable and uncontrolled generation and development of environmental hazards, threats and risks, as well as contributes to the preconditions for the occurrence of natural and technogenic emergencies. The study aims to systematically assess and develop ways to solve the problems of preventing unfavorable technospheric situations in municipal territories in the context of an ever-increasing technogenic impact of production and consumption wastes. The study emphasises the search for methods, organisational-technical measures and best available technologies for preventing natural and technogenic emergencies, as well as their socio-economic, natural-resource, environmental and other adverse consequences. A system analysis of quantitative and qualitative indicators, parameters, factors and conditions, affecting events and formation processes of environmental hazard sources, represented by end-of-life, spent, utilised construction and other products, formed in the process of human activity and life support of settlements, is carried out. Based on the results of a joint research, the authors made an attempt to form an idealised conceptual model of a resource-saving system for an environmentally safe management of life support production and consumption wastes in technospheric territories.
