In the linear economy, raw natural resources are taken, transformed into products, and disposed of. On the opposite, a circular economy model aims to close the gap between the production and the natural ecosystems' cycles – on which humans ultimately depend.
The world's population is growing, and the demand for raw materials is increasing. However, the supply of crucial raw materials is limited. In addition, extracting and using raw materials has a major impact on the environment. It also increases energy consumption and CO2 emissions. However, smarter use of raw materials can lower CO2 emissions.
