Because it is not possible to recycle energy, there is no mention of energy cycles or energy cycles, but of ‘cascade type energy flows’ ( Ellen MacArthur Foundation, 2015a). The circular economic system is fed by renewable energy sources. Just like raw materials and products, energy also lasts as long as possible in a circular economy.

In this system, it is therefore not only important that materials are recycled properly, but also that products, components and raw materials remain of high quality in these cycles ( Korhonen, Nuur, Feldmann & Birkie, 2018).Ĭirculaire economie vraagt om systeemdenken: bedrijven moeten niet langer gefocust zijn op persoonlijk financieel gewin maar op het optimaliseren van het gehele systeem. Producers take back their products after use and repair them for a new useful life ( Ellen MacArthur Foundation, 2015a). Toxic substances are eliminated and residual flows are separated into a biological and a technical cycle. There is no such thing as waste, because every residual stream can be used to make a new product. In a circular economy, material cycles are closed following the example of an ecosystem. Some researchers argue that social inclusiveness is also a necessary part of the circular economy ( Korhonen, Honkasalo and Seppälä, 2018). Het sluiten van die kringlopen vereist veel meer dan alleen What is the difference between a circular and linear economy? Three elementsĪccording to Korhonen, Nuur, Feldmann & Birkie ( 2018), definitions that focus on system change often emphasize three elements, which are further explained below: In een circulaire economie sluiten we de kringlopen van al deze grondstoffen. Simpel gezegd: in een lineaire economie delven we grondstoffen, we verwerken de grondstoffen tot een product en na gebruik gooien we het product weg. When these parts can no longer be reused, the metal, textile and plastic of the parts can be melted down so that a new car can be made of them (recycling).Įen circulaire economie is fundamenteel anders dan een lineaire economie. If the engine of a car is broken, it can be repaired or the chassis and interior of the car can be used to make or refurbish another car (reuse). This reduces the use of raw materials (reduce). Sharing cars, from companies such as MyWheels and WeGo, mean that fewer people have to buy their own cars.
Definitions that focus on resource use often follow the 3-R approach: The diversity of definitions also makes it more difficult to make circularity measurable.ĭefinitions often focus on the use of raw materials or on system change. A philosopher of science emphasizes a different aspect of the concept than a financial analyst. There are so many different definitions in use, because the concept is applied by a diverse group of researchers and professionals ( Kirchherr, Reike & Hekkert 2017).

More than 100 different definitions of circular economy are used in scientific literature and professional journals.
