Why are 'closed loop' systems considered more sustainable?

Closed loop systems are considered more sustainable because they enable the continual reuse of resources for multiple purposes. In these systems, materials are kept in circulation rather than being disposed of after a single use. This approach minimizes waste and reduces the demand for new resources, leading to less environmental impact and lower energy consumption associated with the extraction and processing of raw materials.

By emphasizing the recycling and repurposing of materials, closed loop systems contribute to a more efficient and sustainable economy. They help in conserving natural resources, reducing pollution, and fostering a regenerative approach to production and consumption. This ultimately creates a more resilient systems model that can adapt to changing environmental conditions while maintaining resource availability for future generations.
