What are the three modes of circular economy?

Traditional model, process end management model and circular economy model.

Traditional mode: it is a one-way linear open economic process of "resources-products-pollution discharge", which emphasizes the conquest of the environment and lacks environmental awareness.

Governance model at the end of the process: the method is "pollution first, then governance", and after the economic development has eaten up the consequences of environmental pollution, we will pay attention to environmental protection. The terminal processing cost is high and the technical difficulty is great, which can't contain the pollution.

Circular economy mode: advocating the harmony between economy and environment, emphasizing "clean production", using the closed-loop reaction process of "resources-products-renewable resources" to reduce, reuse and recycle the use of resources, and finally achieving the goal of "optimal production, optimal consumption and minimum waste".
