Kreislaufwirtschaft, or circular economy, is an economic model aimed at minimizing waste and making the most of resources. It emphasizes reusing, recycling, and refurbishing products to extend their lifecycle. This approach contrasts with the traditional linear economy, which follows a "take, make, dispose" pattern. In a circular economy, materials are kept in use for as long as possible, reducing the need for new resources. This model promotes sustainability and environmental protection by lowering pollution and conserving natural resources. Key concepts include recycling, sustainability, and resource efficiency.
