Closed Loop

Closed loop processes are the consummate examples of circularity. In these systems, products are designed and managed so that when they reach the end of their useful life, they can be disassembled and have their parts and materials used in new products of the same type. It can also describe support systems in a factory, such as a closed-loop cooling water system, where the same water is recirculated through the system with minial loss, avoiding the need to continually bring fresh water into the factory. In this Toolbox, products and systems that fit in a broader definition of closed loop are not included, where a product is recyclable and contains recycled content, but the two processes are not directly linked or considered together.
