A model of resource production and consumption in any economy that involves **sharing, leasing, reusing, repairing, refurbishing, and recycling** existing materials and products for as long as possible.[2][3][4][5] The concept aims to tackle global challenges such as **climate change, biodiversity loss, waste, and pollution** by emphasizing the design-based implementation of the three base principles of the model. The main three principles required for the transformation to a circular economy are: designing out **waste** and pollution, keeping products and materials in **use**, and **regenerating** natural systems.`
