Towards Circular Construction: Quantitative Sustainable Design for Recycling and Reusing Anthropogenic Resources

Date, time & venue

28th September 2022 (Wednesday), 17:00-18:00, Seminar via Zoom Meeting


Organized by

HKIE Civil Division and The Hong Kong Polytechnic University


Programme Highlight

As of 2019, there are more than 45,000 buildings in Hong Kong, of which about 8,000 buildings are aged 50 years or above. The older the physical age of a building, the more likely it will be destructed and reconstructed, indicating the potential release of anthropogenic resources of the building. Annually, Hong Kong generates more than 20 million tons of construction and demolition wastes. These anthropogenic resources, including rock, concrete, and soil, were previously used as fill materials for land development for the fast-growing permanent development. With increasing awareness of environmental protection in Hong Kong, it is now a critical problem on how to accommodate these surplus materials. One solution to ease the burden of filling capacity for disposing of these wastes is to recycle these anthropogenic resources. To address the aforementioned sustainability and recycling issue in the construction industry, a city-scale anthropogenic resource recycling management system is proposed to identify and estimate the supply of and demand for recycled resources in the construction industry. A systematic LCA/LCCA analysis will be included in the proposed framework to evaluate the environmental and social impacts of using recycled resources in the context of uncertain construction demand in the future.

Dr. Mark S.C. Hsu

Shu-Chien (Mark) Hsu is an Associate Professor at the Department of Civil and Environmental Engineering in the Hong Kong Polytechnic University. The objective of Dr. Hsu’s research group is to study critical challenges and understand the interactions between people to engineered and planned services such as water/wastewater, food waste, transportation, ecosystems, and sustainable and resiliency infrastructure. His research is inherently interdisciplinary, integrating theories and methods from multiple disciplines including data science, system modeling, and complex systems. His work has been published in high-quality peer-reviewed journals in construction engineering and management (e.g. Automation in Construction, Journal of Management in Engineering, Journal of Construction Engineering and Management, etc.) and in environmental engineering (e.g. Environmental Science and Technology, Applied Energy, Energy Policy etc.)
