Learning points

The Ellen MacArthur Foundation has produced a well-known graphical representation of the circular economy known as the "butterfly diagram".

The central component shows how design, materials, and energy add value at various stages.

The right wing shows how various feedback loops can be used to retain and enhance value for technical materials and products.

The left wing illustrates how biological materials can be reused and cascaded until they are returned to the natural in such a way as to enhance and regenerate the biosphere.
