Digital Twin-Enabled Building Demolition Waste Trading Workflow

With the increasing demand for housing renovation and demolition, the amount of building demolition waste is also rising year by year. However, due to the low recycling and reusing rate, a large proportion of waste was disposed by landfill, which has a great impact on the environment. Aiming at this problem, this paper proposed a digital twin-enabled building demolition waste trading workflow. The digital twin model could integrate, analyze, and display the demolition-related data in real-time, which is the basis of building demolition waste trading. Through the two-way information flow realized by the trading platform, contractors and recyclers could quickly know each other's products and needs. The digital twin-based trading workflow can benefit for improving the transaction rate, thus improving the recycling and reusing rate of the building demolition waste.
