Circular Economy

From Sikipedia:

A circular economy (also referred to as circularity or CE) is a model of resource production and consumption in any economy that involves sharing, leasing, reusing, repairing, refurbishing, and recycling existing materials and products for as long as possible.

This type of economic system prioritises reducing waste as much as it can, though by itself, is not enough to be completely self-sufficient (see Degrowth)
