Cradle to gate describes a product boundary from raw material extraction through production up to the factory gate, excluding later use and end-of-life stages.
Overview
What it means in practice
Cradle to gate should be read as a materials and product-life-cycle term. Its meaning depends on the product boundary, material flow, evidence and intended claim.
In practice, users should state the standard, boundary, method and evidence behind the term. That keeps cradle to gate useful without overstating assurance or performance.
Why it matters
Cradle to gate matters because circular-economy language can shape design choices, procurement, reporting and product claims. Clear boundaries help readers see whether the term describes intention, process or measured outcome.
Common misconception
A common error is to use Cradle to gate as a broad environmental improvement claim. The stronger approach is to state the product boundary, material pathway, evidence and trade-offs.
Review questions
What criteria or boundary gives the term meaning? Who assessed or evidenced it? What limitation should be stated so a reader does not treat the term as broader than it is?

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
