ABSTRACT
With the acceleration of urbanization, the annual production of construction waste has been increasing, and its disposal has become a global concern. Traditional landfill and stockpiling methods not only consume large amounts of land resources but may also lead to environmental pollution, thus highlighting the urgent need to explore efficient and environmentally friendly resource recovery technologies. This study aims to systematically analyze the compositional characteristics and potential value of construction waste, develop resource recovery technologies suitable for various scenarios, and evaluate their economic and environmental benefits. By integrating laboratory experiments, numerical simulations, and engineering demonstrations, this research conducted an in-depth investigation into the classification and recycling of construction waste, optimization of crushing and sorting processes, and preparation technology of recycled aggregates. Furthermore, through practical engineering projects, the feasibility of recycled building materials was verified in terms of structural performance and durability. The results indicate that by optimizing sorting processes and modifying treatments, the quality of recycled aggregates can meet current standard requirements. Concrete and blocks prepared from recycled aggregates exhibit favorable mechanical properties and environmental advantages. Additionally, this study proposes an integrated technical system for the resource recovery of construction waste, which significantly improves resource utilization efficiency and reduces overall costs. The innovation of this system lies in its ability to organically combine the classified processing of construction waste with high-value utilization, providing critical technical support for the development of the construction waste resource recovery industry. The research findings not only offer new insights into solving construction waste management challenges but also lay a theoretical and practical foundation for achieving sustainable development goals in the construction sector.
