What is the circular economy?Show answer
A circular economy is designed to break that line into a loop. It aims to design out waste and keep materials in use for as long as possible through reuse, repair, remanufacture and recycling, mimicking the closed nutrient cycles of natural ecosystems. The same molecules circulate rather than being extracted once and dumped. This cuts extraction and waste simultaneously and captures the value embedded in materials.
