随着我国城镇化进程步入存量更新主导阶段，以小规模、高频次、空间分散为特征的城市更新活动与新城建设并行推进，导致建筑垃圾持续增量并成为城镇固体废弃物的主体组成部分。其低效处置不仅加剧“垃圾围城”困境，更对“无废城市”建设及双碳目标达成形成显著制约。尤为突出的是，城市更新场景下建筑垃圾产生节点的碎片化分布、物质成分的异质性增强及产生量的动态波动特征，与传统集中式处置模式的规模化、连续性要求形成结构性冲突，进一步暴露治理体系存在顶层设计缺位、全流程衔接断层、资源化水平低下及跨部门协同失效等系统性问题。面对城市更新所带来的一系列挑战，本文构建“事前分析-分类收集-规范运输-科学处理-精准管控”的全过程规划管控技术体系。通过创新建筑垃圾分类处置技术路线、智慧化管理监督系统及规划实施机制，形成涵盖标准制定、设施布局与政策保障的系统性解决方案，为破解存量更新中建筑垃圾治理的适配性困境提供可复制的技术路径与政策工具。
Abstract：As China's urbanisation process enters a stage dominated by stock renewal, urban renewal activities characterised by small scale, high frequency, and spatial dispersion are being carried out in parallel with new city construction, leading to a continuous increase in construction waste and making it the main component of urban solid waste. Its inefficient disposal not only exacerbates the ‘garbage encircling the city' dilemma but also significantly constrains the construction of ‘waste-free cities' and the achievement of ‘dual carbon' goals. Particularly prominent is the structural conflict between the fragmented distribution of construction waste generation nodes, the enhanced heterogeneity of material composition, and the dynamic fluctuations in generation volume in urban renewal scenarios, and the scale and continuity requirements of traditional centralized disposal models. This further exposes systemic issues in the governance system, including deficiencies in top-level design, gaps in process integration, low resource recovery rates, and ineffective interdepartmental coordination. In response to the challenges posed by urban renewal, this paper proposes a comprehensive planning and control technical framework encompassing ‘pre-analysis-classified collection-standardised transportation-scientific processing-precise management' By innovating construction waste classification and disposal technologies, intelligent management and supervision systems, and planning implementation mechanisms, this framework offers a systematic solution covering standard formulation, facility layout, and policy safeguards, providing replicable technical pathways and policy tools to address the adaptability challenges in construction waste management during existing urban renewal projects.
