The global economy still functions in a linear manner and is characterized by the extraction, production, consumption, and disposal of materials. This is a problem given that we live on a planet with finite resources. Yet the shift to a circular economy, in which businesses recover or recycle resources used in their value chain, has remained elusive, despite offering trillions of dollars in value creation. Barriers include the low residual value of used products, an inability to collect materials, prohibitive costs of separating and processing materials, and lack of traceability of products and materials that are being recycled.
