Closed-Loop System

Closed-Loop System

Closed-Loop System is a setup in sustainable engineering where materials or energy are reused within the same process, so nothing is wasted and everything gets a new use. For designers, this means thinking about how every part of a product or building can be taken apart and used again, like using modular parts that fit together in different ways or choosing materials that are easy to recycle. In some projects, water used for cooling or cleaning gets filtered and sent back into the system instead of being thrown away, which saves resources and lowers costs. Closed-loop thinking can help designers plan for the whole life of a product, making sure it keeps its value and purpose for as long as possible. This approach helps create systems where waste is turned into something useful, making the whole process more efficient and better for the environment.
