What it is

Chain of Custody Preparation, without the jargon

Chain of custody is the backbone of every recycled and sustainability certification. We help organisations select and implement the right model — product segregation, controlled blending or mass balance — with the input records, transaction certificates and reconciliation that let certified material be tracked from source to finished product.

Why it matters

Why recyclers, manufacturers act on this

  • Every recycled and sustainability standard rests on a sound chain of custody
  • The right custody model depends on process, material and claim type
  • Robust records and reconciliation are what make claims audit-proof

How we deliver

A clear, auditable process

  1. 01

    Choose segregation, controlled blending or mass balance to fit the operation.

  2. 02
    System setup

    Input records, transaction certificates and reconciliation procedures established.

  3. 03
    Validation

    Internal reconciliation and readiness check before certification audit.

Three ways to track certified material

The custody model decides what you can claim

Every recycled and sustainability certification rests on a chain-of-custody model — and the model you choose sets exactly how certified material is tracked and what claim the finished product can carry.

How certified material is tracked
Product segregationCertified kept physically apart
Physically separatedNever mixed with conventional
Highest integrity
Fully certified outputThe claim equals the input
Controlled blendingCertified mixed at a known ratio
Fixed input ratioBlended with conventional material
Ratio tracked
Proportional claimOutput reflects the blend
Mass balanceCertified volume tracked in the books
Volume bookkeepingCredits reconciled, not physical flow
Accounting model
Attributed outputClaim assigned by credits

The custody model is not a free choice. It must match how material actually moves through your process — pick the wrong one and the claim will not survive audit.
