The concept of the circular economy is based on the idea that products can be reused, and after reuse the materials can be reclaimed to enter again into the system of production. If all materials could be reused in this way, further extraction of raw materials would be needed only where more goods were in use. The concept thus aligns with the aim of long term sustainability, even where raw materials are becoming scarce.
Wikipedia defines the circular economy as "an economic system aimed at minimizing waste and making the most of resources".
The idea is also related to reflection on the cycles of nature.
"The Circular Economy is based on the abundance of flows generated from our alignment with ecosystemic metabolisms. Put simply, we should be imitating natural cycles as closely as we possibly can.
The Circular Economy holds the keys of positive perspectives about the future of business, the future of the environment and about our future as people. It depicts a world without waste, where unused resources will find a function in an economy that will regenerate itself while growing within our systemic boundaries"
— Alexandre Lemille 
Other people doubt the realism of this vision. For example, Kris De Decker, in How Circular is the Circular Economy (2018), gives a critical summary of the limitations of the Circular Economy, pointing out how modern manufacturing makes it difficult to imitate the recycling that nature performs.
