The article considers the role of secondary use of building materials in the circular economy. The paper considers the method of cascading use of wood, used in the practice of European specialists, which allows to increase the period of use of building materials. The author concludes that nowadays the problems of resource shortage and rapid climate change are encouraging society to move towards more sustainable solutions for the construction sector. Wood, as a widely available and naturally grown material, is of particular importance for achieving the environmental goals set by the EU and national authorities. The use of wood in construction has increased in recent decades. However, the use of a secondary method of wood processing in the circular economy is rarely used in practice, although the economic effect of this process is quite high.
The article considers the features of complex optimization of construction waste management and defines its role in the formation of the concept of "sustainable construction". The authors note that in order for the construction, demolition and waste management industries to remain competitive in the global market, they must continue developing and implement innovations in the supply chain to improve efficiency, sustainability, and reduce energy, waste, and resource consumption. This requires serious research on intelligent, mobile, and integrated systems. Radically advanced robotic artificial intelligence systems for sorting and processing must be developed with an emphasis on the required reuse of materials and components. Many industries face an uncertain future in which the applicability of today's technological constraints cannot be assumed. The construction industry is likely to be significantly impacted by the capabilities of transformative technologies such as artificial intelligence, additive manufacturing, nanotechnology, virtual reality, and robotics. The application of such technologies presents significant opportunities for this industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
