  • The company implemented a closed-loop system to recycle materials and reduce waste in their production process.

Meanwhile, researchers are implementing ways to use helium more sustainably, such as using closed loop systems.

Examples

  • A closed-loop system ensures that every material used in manufacturing is returned and repurposed efficiently.

  • In our environmental course, we learned about the benefits of a closed-loop system where products are reused instead of discarded.

  • Right now, they're favoring permissioned closed loop systems rather than permissionless openly systems.

  • This arrangement leads to a closed-loop system in which the electronic-drive circuits receive feedback about the actuator's output, including displacement and force.

Morphology

closed-loop + system

The compound 'closed-loop' is compositionally built from 'closed' (not open) and 'loop' (a circuit or cycle), so a learner who knows those words plus 'system' can infer a system in which outputs loop back as inputs — i.e. resources circulate rather than flow out. However, the specific technical details (recovering, cleaning, reintegrating materials) and domain-specific usage may not be fully predictable for a B1 learner without prior exposure, so the expression is only partially transparent.

Etymology

The term closed-loop system comes from the picture of a closed circle or loop where materials move around and return to be used again. So, it means a system that 'recycles' or 'reuses' products so they keep moving instead of becoming waste.
