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.

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.
