Overview
What it means in practice
Feedstock 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 feedstock clear enough to support review without turning it into a broad claim.
Why it matters
Feedstock 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 Feedstock 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 a raw material or input used in a production, recycling, energy or conversion process.
Its correct use depends on the product system, life-cycle stages, functional unit, geography, timeframe and measurement method.
