Destruction of buildings and use of materials from renovated urban territories

Introduction. Reuse of construction materials, products, and structures from demolished buildings and installations is an actual problem. The solution to it will improve the ecological situation. The study is aims at the determination of the causes of urban area renovation and searches for the most efficient technologies of building demolition with the reuse of the generated materials, products, and structures. Materials and methods. The study used systematization, structural analysis, comparative analysis, a theoretical generalization of the data obtained in a detailed analysis of literary and statistical sources, field surveys of objects. When field examining, photography methods were used. Results. Existing technologies of the building demolition, construction waste recovery, and reuse of construction materials generated using innovative item-by-item demolition technologies were revealed and systematized. Causes and main trends of urban territory renovation were analyzed. The paper studied Russian and foreign technologies of the building and installation demolition. The pros and cons of various demolition types are shown in terms of their environmental friendliness and economic efficiency. Conclusions. The experience of constructing low-rise buildings and intrasettlement roads showed that the item-by-item disassembly of buildings using modern equipment and machinery with the subsequent reuse of construction materials, products, and structures is efficient, economical, and environment-friendly. It is proven that the reuse of construction materials, products, and structures results in a significant reduction in the cost of erected installations. The results of the study can be applied in low-rise construction around the world.
