The need for a transition to a circular economy is increasing as the environmental crisis worsens and the demand for natural resources grows. Circular economy is important also for self-sufficiency, security of supply and sustainable food system. In a circular economy existing assets are used as efficiently as possible by keeping products and materials in effective use for as long as possible. The circular economy does not only encompass recycling but also other new operating models and services in the economy, including sharing, renting, repairing and reuse.
