Opaque identity
A stable public identifier avoids exposing internal project IDs and provides a durable reference across documents and events.
RubblePass Material Passports
A durable identity for a material batch and the evidence that follows it.
A RubblePass passport links an approved material record to a QR code, evidence summary, current state and custody timeline. It is designed to distinguish planning estimates from accepted quantities and to keep corrections visible.
A passport records evidence and decisions. It is not a structural certificate, hazardous-material clearance, permit or official waste-transfer document.
Passport anatomy
The useful context stays attached to the batch.
Real QR code
The printable QR encodes the exact public passport URL so a scan opens the same controlled record.
Quantity state
Estimated P10/P50/P90 quantities and accepted measured quantities are labeled separately rather than collapsed into one number.
Evidence summary
Evidence level, condition, review status, limitations and approved document summaries show why the current state exists.
Controlled visibility
Private fields, exact addresses, personal data and confidential evidence remain permissioned independently of the public passport.
Version and correction history
A correction creates a linked record. Earlier custody events are not silently erased or rewritten.
Custody timeline
Verification is earned through accepted evidence.
A passport can begin as an approved planning record. Its verified state changes only as authorized events and destination evidence are added.

Passport created
An eligible, approved material batch receives its identity, initial published fields and visibility policy.
Preliminary / Approved - 02
Reservation accepted
The source organization records the selected route, counterparty and planned collection window.
Reserved - 03
Collection recorded
An authorized actor records collection time, quantity method, generalized location and supporting evidence.

Delivered - 05
Destination decision
Accepted, partially accepted or rejected quantities are recorded. Only accepted evidence contributes to verified outcome totals.
L3 custody
- Passport ID, material identity and generalized source
- Estimated quantity and verified quantity as separate fields
- Evidence level, condition, route and current state
- Custody events, last updated date and visibility state
- Print-friendly layout for labels and records
- Correction and version history without destructive edits
Start with evidence
Scan the sample record, inspect the evidence, and print it.
The public example shows how identity, quantities, review status, custody and limitations can remain legible in one record.
