The circular economy system diagram, known as the butterfly diagram, illustrates the continuous flow of materials in a circular economy. There are two main cycles – the technical cycle and the biological cycle. In the technical cycle, products and materials are kept in circulation through processes such as reuse, repair, remanufacture and recycling. In the biological cycle, the nutrients from biodegradable materials are returned to the Earth to regenerate nature.
Find out more about each side of the butterfly diagram – the biological cycle and the technical cycle. These pages focus on the different stages of the two cycles and explain the concepts used.
A circular economy eliminates waste, circulates products and materials, and regenerates nature.
