closed loops

Paths without endpoints

Closed loops are systems where the output feeds back into the input, creating a self-regulating cycle.

In engineering, a closed-loop system adjusts itself based on feedback—a thermostat that turns heating on and off is a classic example.

In manufacturing, closed-loop recycling returns waste materials directly into the production process.

The term often appears in sustainability discussions: We need to move toward closed loops where nothing is discarded.
