Illustrative reference architecture

The Circular Material Passport Journey.

How a material batch moves from source claim to authorised industrial use, reuse or recovery.

Physical identity anchors the item. Authority governs the claim. Receipts prove the lifecycle event.

The problem

Traceability is not enough.

A material passport becomes useful only when another role can responsibly rely on it. Claims, test reports, lifecycle calculations, process notes and commercial approvals often remain distributed across separate systems.

KATLAS does not create another material data lake. It governs the journey between evidence holders.

Shared journey rail

Seven stages, one consistent loop.

At every stage of the material's life, the same consistent loop holds:

Receive → Assess locally → Act under authority → Sign outcome → Pass controlled evidence onward

Stage 01
Material identity created
Stage 02
Source and process claims issued
Stage 03
Test evidence requested and verified
Stage 04
AI / LCA / quality assessment advises
Stage 05
Manufacturer accepts, conditions or rejects use
Stage 06
Lifecycle or process event recorded
Stage 07
Recovery, reuse or recycling claim closes the loop

Five role cards

What each evidence holder receives, assesses and passes on.

Role

Material Producer

Incoming request: Request for source claim, batch identity and process notes.
Evidence available: Production records, source declarations, batch identity, process-condition log.
Local assessment: Has the batch been correctly identified and is the source claim consistent with internal records?
Permitted action: Issue or refuse the source claim against this batch identity.
Receipt issued: Source-claim receipt referencing batch, declared source class, withheld commercial detail.
Next handoff: Pass the source claim and batch identity to the test and certification partner.

Role

Test & Certification Partner

Incoming request: Request to verify a property, conformance or certification status for a batch.
Evidence available: Test methodology, raw test data, certification authority, expiry.
Local assessment: Does the held evidence support the requested verification within scope and date?
Permitted action: Confirm, refuse, or release a bounded verification claim.
Receipt issued: Verification receipt referencing test scope, validity window, withheld raw data.
Next handoff: Pass verification reference forward; raw data remains in custody.

Role

AI / LCA / Quality Tool

Incoming request: Request to calculate, compare, screen or summarise across permitted claims.
Evidence available: Authorised inputs, reference thresholds, model version, advisory scope.
Local assessment: What can be advised from permitted material without overriding test or commercial decisions?
Permitted action: Surface advice, missing claims, threshold comparisons or inconsistencies. Never approve material use.
Receipt issued: Advisory receipt referencing inputs used, model version, advisory only.
Next handoff: Pass advisory result to a named authorised role.

Role

Manufacturer / Specifier

Incoming request: Request to permit a specific industrial use under a specification and policy.
Evidence available: Specification, prior approvals, fitness criteria, exception policy.
Local assessment: Do the available claims and advice meet the specification within authority?
Permitted action: Accept, condition, escalate or refuse the proposed industrial use.
Receipt issued: Use-permission receipt referencing specification, condition set, withheld commercial terms.
Next handoff: Pass permitted-use reference to recovery and lifecycle handlers.

Role

Recovery / Reuse Partner

Incoming request: Request to claim a recovery, reuse or recycling event against the batch.
Evidence available: Recovery process record, condition assessment, downstream destination claim.
Local assessment: Is the recovery claim attributable, in-scope and not already retired?
Permitted action: Record, refuse or escalate the recovery event.
Receipt issued: Lifecycle-event receipt referencing batch, event class, downstream reference.
Next handoff: Close, fork or pass the batch identity onward to its next industrial life.

AI boundary

AI may suggest. Authorised roles decide.

AI may

· calculate
· identify a missing claim
· compare a threshold
· detect an inconsistency
· draft an advisory summary

AI may not

· approve material use
· override test evidence
· release restricted evidence
· commit a manufacturing decision

Closing pattern

From traceability to accountable industrial coordination.

Custody

Each organisation retains control of raw evidence, technical reports, proprietary process knowledge and commercial thresholds.

Authority

Every claim, approval, exception and release is tied to a named role, purpose and decision boundary.

Receipts

Each lifecycle event records the outcome, authority basis, evidence references and what was shared or withheld.

The passport does not merely describe the material. It governs what authorised parties may do with the evidence around it.
