A business model canvas for construction waste resource use under dual carbon targets

For several years, as China's urbanization efforts have continued to advance, construction waste treatment has been a priority issue. Many treatment modes focused on sustainability have been researched, while the current method of construction waste treatment in China remains stuck in the linear economic mode. The circular economy mode is developing slowly, the construction waste resourcing and treatment industry is underdeveloped, and the business model is insufficiently mature. This paper analyzes the main elements in the economic, environmental, and social layers; suggests improvements based on the existing business model canvas; constructs a more targeted business model canvas for construction waste treatment resourcing; and explores the relationship between environmental, social, and economic values. It concludes that the government should guide the promotion of stakeholder cooperation and consider the sustainable use of building materials from the perspective of the whole life cycle and the interrelationship based on stakeholders to promote the application of the circular economy in construction waste resourcing. The economic value of the construction waste recycling industry requires the government's support and encouragement to attract more enterprises to participate in and realize the value of construction waste recycling, create more jobs, and thereby reduce carbon emissions.
