Open-loop recycling
Definition
Open-loop recycling is recycling in which recovered material is used in a different product system or application from its original use.

This reference provides supporting context for how “Open-loop recycling” is defined and used.
Overview
What it means in practice
Open-loop recycling should be read as a materials and circular-economy term. Its meaning depends on the product, material pathway, infrastructure and evidence behind the claim.
In practice, users should state the boundary, material route, measurement method and evidence. That keeps open-loop recycling clear enough to support review without turning it into a broad claim.
Why it matters
Open-loop recycling matters because circularity claims can influence design, procurement, consumer understanding and reporting. Clear wording helps distinguish real material outcomes from broad environmental language.
Common misconception
A common error is to treat Open-loop recycling as proof of circularity by itself. The stronger approach is to state the material route, quality, scale and final use.
Review questions
What boundary or material route is being described? What evidence supports the term? What condition, timeframe or modelling choice should be stated before a reader relies on it?
How it is used
The term appears in product design, procurement, footprinting, material selection, production and end-of-life decisions, where designers, manufacturers, procurement teams, life-cycle practitioners and waste managers use it to classify, assess or communicate recycling in which recovered material is used in a different product system or application from its original use.
Its correct use depends on the product system, life-cycle stages, functional unit, geography, timeframe and measurement method.
