Abstract: With continuous acceleration of Shanghai’s urbanization process, the annual declared amount of construction waste has exceeded 100 million tons for two consecutive years. It means that the management of construction waste is facing arduous situation. To effectively address the challenges arising from the construction waste management process, the state and Shanghai have successively introduced many policies. However, we are still facing a series of challenges such as shrinkage of disposal space, increase of regulatory difficulties, and obstruction of resource utilization. The cost and benefit also needs to be further optimized. Therefore, under the goal of the “double carbon” and “zero-waste cities”, by analyzing the current situation of construction waste management in Shanghai, this paper pointed out the bottleneck benefits faced in the whole cycle management process from source generation to end disposal, and proposed that cost-benefit optimization should be taken as the core to solve the problem of construction waste governance. Furthermore, it proposed to build a management path for the whole chain optimization of “source reduction-intelligent supervision-resource utilization” for construction waste. This path aims to promote the transformation of construction waste management from “passive disposal” to “active value-addicition”, so as to achieve the dual dividends of environment and economy.
