Abstract

Efficient and cost-effective management of construction and demolition (C&D) waste is a global challenge. This research integrates Material Flow Analysis (MFA) and Geographic Information Systems (GIS) to overcome limitations of traditional methods in accurately estimating waste generation. We utilizing building and real-estate data to quantify C&D waste at 100-meter grids, and evaluate the suitability of disposal facility locations based on the capacity gaps. It reveals that: Annual C&D waste output in Beijing central area was approximately 10 million tons, over 80 % is generated by urban renewal. Annual recycling value reaches US$318.64 million. Considering the waste disposal needs, the suitable land for new facilities represents only about 3 %, yet can achieve source control. We recommend source separation and proximity-based transportation for recycling and disposal of C&D waste, offering new insights and actionable solutions for waste quantification management and sustainable development in regions at different stages of urbanization worldwide.

建筑与拆除废弃物估算与处置设施选址评估：综合物流分析与地理信息系统方法

高效、经济地管理建筑和拆除（C&；D）废物是一项全球性挑战。本研究将物料流分析（MFA）与地理资讯系统（GIS）相结合，以克服传统方法在精确估算废物产生量方面的局限性。我们利用建筑和房地产数据来量化100米电网的C&；D废物，并根据容量差距评估处置设施位置的适用性。结果表明：北京市中心城区年垃圾产生量约为1000万吨，其中80%以上来自城市更新。年回收价值达3.1864亿美元。考虑到废物处理的需要，新设施的合适土地只占约3%，但可以实现源头控制。我们建议在垃圾回收和处置方面实行源头分离和就近运输，为全球不同城市化阶段的地区的垃圾量化管理和可持续发展提供新的见解和可行的解决方案。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
