In recent decades, research on treatment and recycling of construction and demolition waste (CDW) has rapidly increased due to its substantial environmental, social, and economic impacts. Despite the growing interest in this field, there is a noticeable lack of comprehensive and systematic analysis offering a clear overview of the development context and quantitative trends. To address this gap, this study conducted a systematic bibliometric overview that covers publishing trends, collaborative networks among countries, institutions and research teams, co-citation analysis of literatures, and keyword co-occurrence analysis using literature data-driven visualization. Research trends and future perspectives were identified based on the results and comprehensive review as well as the keywords clusters visualized by literature data. These perspectives highlight several research opportunities. (1) Advanced technologies for CDW treatment are underutilized, which necessitates government involvement and a national disposal charging system. (2) There is a lack of interdisciplinary integration in CDW research. (3) A universally applicable life cycle assessment system for CDW recycling needs to be developed. (4) Research on heavy metal migration and long-term stability in recycled CDW is limited. (5) More studies on CDW reduction in the design stage are warranted, with emphasis on urban planning, building quality, design optimization, and resource estimation. These findings not only enhance understanding of the research trends in treatment and recycling of CDW but also for provide insights for practitioners and researchers at the evolving frontiers of the field.
近几十年来，由于建筑和拆除废物（CDW）对环境、社会和经济的重大影响，对其处理和再利用的研究迅速增加。尽管人们对这个领域越来越感兴趣，但缺乏全面系统的分析，无法清晰地概述发展背景和量化趋势。为了解决这一差距，本研究进行了系统的文献计量概述，涵盖了出版趋势、国家间的合作网络、机构和研究团队、文献的共被引分析以及使用文献数据驱动可视化的关键词共现分析。根据结果以及对综合审查和文献数据可视化的关键词聚类，确定了研究趋势和未来展望。这些观点强调了几个研究机会。（1）CDW 处理的先进技术未得到充分利用，需要政府介入和建立国家处置收费制度。（2）CDW 研究中缺乏跨学科的综合。（3）需要开发适用于 CDW 回收的通用生命周期评估系统。（4）对再生 CDW 中重金属迁移和长期稳定性的研究有限。（5）需要更多研究在设计阶段减少 CDW，重点是城市规划、建筑质量、设计优化和资源估算。这些发现不仅增强了对 CDW 处理和再利用研究趋势的理解，也为该领域不断发展的前沿的实践者和研究人员提供了见解。
