The document discusses the linear "take-make-waste" model of production and consumption that has dominated the last 150 years. This linear model is unsustainable as it depletes natural resources and produces large amounts of waste. The document introduces circular economy as an alternative model that aims to eliminate waste and the use of toxic chemicals, be powered by renewable energy, and design products to be reused and recycled to keep resources in use for as long as possible. It provides examples of companies implementing circular economy principles and argues that the circular model represents significant opportunities for cost savings, risk mitigation, innovation and job creation compared to the linear economy.
