Abstract
The anthropogenic flow of material was thoroughly discussed in Chaps. 4 through 6; specifically, the basic process of material circular flow was analyzed to obtain the basic laws of ecological efficiency, circulation rate, yield change, and other parameters that change during the circular flow process.

8.1.1 Topic 1 Discussion
Based on material circular flow, clarify the internal coupling relationship between material flow and energy flow/value flow as the important topic of a circular economy. This was the study to be implemented by the STAF team at Yale University and is the scientific issue to be further researched. Furthermore, from the perspective of natural science funds supported by the state in recent years, an increasing number of people are attempting to perform related research. In this chapter, beginning with the simplest model framework, partial research results are shared. There is a significant number of problems to be further studied. Therefore, please consider and discuss the following topics:
-
(1)
A certain material has multiple purposes; how can you explain its relationship between material flow and value flow?
-
(2)
In the same service or product, there are various substances, and each is important on a large scale, for example, there is M, N in an alloy. Under this circumstance, it is difficult to choose one substance as representative of the product; therefore, how do you analyze the problem of value flow?
-
(3)
What type of coupling relationship exists among material, energy, and value in a circular economy? How do you explain them?
-
(4)
In a circular economy, what type of coupling relationship exists among material flow, energy flow, and value flow among multiple materials in multiple services? How do you explain them?
8.1.2 Topic 2 Discussion
Previously, we have discussed the anthropogenic flow of material and energy and the flow of value. What type of practical significance do these flows have? How do you apply the latter in practice? Please choose a familiar region, and specific to a typical resource or environmental problem, discuss how to explore the solutions to the problems via the above methods. Create a research outline.
8.1.3 Homework and Presentation After Class
Specific to the topic of value flow discussed in class, locate a related paper for class sharing in a group.
Alternatively, specific to a selected topic, locate an application paper of the analysis of material flow, energy flow, and value flow under specific dimensions for sharing in class groups. The grading scale is shown in Table 8.5.
