In many ways, the Circular Economy model shares key ideas with others such as Biomimicry, which studies nature and imitates its designs and processes to solve human problems; the Cradle to Cradle proposal, which advocates for extending a product lifespan; and the Blue Economy, that uses open-source solutions based upon natural processes.

== What are the key principles of the Circular Economy? ==
 +
 +
The Circular Economy is based on three key principles, as explained by the Ellen MacArthur Foundation, one of the main organizations promoting this economic model worldwide:
 +
 +
#Preserving and enhancing natural capital by controlling finite stocks and balancing renewable resource flows. That is, using as less raw resources as possible and if totally needed, choosing renewable or better performing ones.
 +
#Optimizing resource yields by circulating products, components, and materials at the highest utility at all times in both technical and biological cycles. This means designing for remanufacturing, refurbishing, and recycling to keep components and materials circulating in and contributing to the economy.
 +
#Fostering system effectiveness by revealing and designing out negative externalities. This includes reducing damage to human utility, such as food, mobility, shelter, education, health, and entertainment, and managing externalities, such as land use, air, water, noise pollution, release of toxic substances, and climate change.
