Dematerialization
Definition
Dematerialization is the reduction of material use needed to deliver a product, service or function.

This reference provides supporting context for how “Dematerialization” is defined and used.
Overview
What it means in practice
Dematerialization 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 dematerialization clear enough to support review without turning it into a broad claim.
Why it matters
Dematerialization 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 Dematerialization 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
Designers, manufacturers, procurement teams, life-cycle practitioners and waste managers use “Dematerialization” in product design, procurement, footprinting, material selection, production and end-of-life decisions.
In each case, the user should state the product system, life-cycle stages, functional unit, geography, timeframe and measurement method; otherwise, the same term may be applied to materially different situations. In this context, it refers to the reduction of material use needed to deliver a product, service or function.
