Wikipedia, Dec. 7, 2021 (A circular economy (also referred to as "circularity" and "CE") is "a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible")

UNCTAD website, Dec 7, 2021: Circular economy (A circular economy entails markets that give incentives to reusing products, rather than scrapping them and then extracting new resources.)

Sustainability Guide website, Dec. 7, 2021: Circular economy (Circular economy is a manifestation of economic models that highlight business opportunities where cycles rather than linear processes, dominate. It is restorative and regenerative by design and aims to keep products, components, and materials at their highest utility and value at all times.)

Oxford dictionaries website, Dec. 7, 2021 (circular economy n. an economic system in which the journey of a product, material, etc., leads back in some way to where it began; (now esp.) a system or process which seeks to minimize or remediate harm to the environment by recycling, reusing, or regenerating products or materials, as a means of reducing waste and more sustainably or efficiently continuing production.)

Macmillan dictionary website, Dec. 7, 2021 (circular economy, an economy that reuses and recycles resources to keep them in play for as long as possible)

US EPA website, Jan. 5, 2022 (What is a Circular Economy? A circular economy, as defined in the Save Our Seas 2.0 Act, refers to an economy that uses a systems-focused approach and involves industrial processes and economic activities that are restorative or regenerative by design, enable resources used in such processes and activities to maintain their highest value for as long as possible, and aim for the elimination of waste through the superior design of materials, products, and systems (including business models). It is a change to the model in which resources are mined, made into products, and then become waste. A circular economy reduces material use, redesigns materials to be less resource intensive, and recaptures "waste" as a resource to manufacture new materials and products)

Here are entered works on the economic system that focuses on reducing waste through restoration, re-design, and re-use of materials.
