What does 'closed loop' refer to in waste management?

'Closed loop' in waste management specifically refers to the practice of returning discarded materials back into the community. This concept emphasizes the importance of recycling and reusing materials to minimize waste and reduce the need for new resources. A closed loop system works towards sustainability by ensuring that materials are continuously cycled back into use rather than being disposed of in landfills or incinerated. By reintegrating these materials into the community, we can conserve natural resources, lower environmental impact, and create a more sustainable and circular economy. This approach stands in contrast to waste methods that involve disposal without consideration for reuse or recycling.
