N/A

it is research idea here.

Reflections:
Is there any relationship between economic trends and the development of a circular economy？E.g,. In 2008, the recession of economic bloom the development of circular economy.
In the future, the topic is how we think about collaboration between different region and countries. So lets say it should be regulation and policy based collaboration among different actors in different region.
The key issue in battery recycling is scalability. The short of scalability is a one of the main reason for the lack of standardisation. So we can try to build the standarlazation from this perspective. We can classify and storage the battery first, then think about further circular actions or second life applications. This will more easy to make economic efficiency.
