A circular business model aims to use resources efficiently and create no waste by keeping materials in continuous use through reuse and recycling. It redefines market growth and value creation to be sustainable. The document explores 10 business model archetypes that enable circularity, including 5 classic circular models of closed-loop recycling, downcycling, upcycling, industrial symbiosis, and collection services and 5 enabling models of product-service systems, lock-in, local loops, modularity, and personalization. The models were developed to inspire Unilever to develop radically different sustainable products and services through market development while decoupling growth from environmental impact.
