Zero waste
Definition
Zero waste is an ambition or management approach aimed at preventing waste and keeping materials in use, rather than sending them to landfill or disposal.

Overview
What it means in practice
Zero waste 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 zero waste clear enough to support review without turning it into a broad claim.
Why it matters
Zero waste 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 use Zero waste as a simple environmental benefit claim. The stronger approach is to state the conditions, timeframe, disposal route and evidence.
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
In professional practice, “Zero waste” helps designers, manufacturers, procurement teams, life-cycle practitioners and waste managers describe or assess an ambition or management approach aimed at preventing waste and keeping materials in use, rather than sending them to landfill or disposal.
It is commonly encountered in product design, procurement, footprinting, material selection, production and end-of-life decisions. A credible application identifies the product system, life-cycle stages, functional unit, geography, timeframe and measurement method.
