The 8 Pillars of Verification

Operational truth. The structural pillars that hold the entire verification system together. Shared with serious partners who need to see the depth.

Verification builds trust. dPRN is the verified outcome.
1

Material Identity

Every material batch receives a unique digital identity at point of entry. Source verified, timestamped, GPS-locked. No anonymous material enters the system.

Unique ID GPS Lock Timestamp
2

Weight Verification

Calibrated weighbridge data with photographic evidence. Cross-referenced against transport manifest. Discrepancies flagged automatically before processing.

Calibrated Scales Photo Evidence
3

Polymer Classification

5-stream polymer sorting verified by type. HDPE, PET, PP, LDPE, PS each tracked independently. Contamination thresholds enforced per stream. Mixed loads rejected or downgraded.

5 Streams Purity Tested
4

Chain of Custody

Unbroken custody record from collection to processing. Every handoff documented. Route tracking ensures no diversion. Material integrity maintained throughout transit.

Route Tracked No Gaps
5

Processing Verification

End-processor confirmation that material was received, processed, and transformed. Output records linked back to input batch. Full loop closed with documented proof.

Processor Confirmed Loop Closed
6

Regulatory Compliance

EPR obligations tracked and evidenced. Waste transfer notes digitised. Environment Agency reporting automated. Every tonne compliant before it counts.

EPR Ready EA Compliant
7

Social Impact Proof

Every tonne generates meals. Verified meal receipts (VMRs) track the social output. Foodbank partnerships documented. Impact is measured, not claimed.

VMR Tracked 40 Meals/Tonne
8

Digital Twin Certificate

Every verified tonne generates a digital certificate. The dPRN is not traded on faith - it's the documented output of pillars 1-7 completing successfully. Greenwashing-proof by design.

dPRN Minted Audit-Ready

The Result

When all 8 pillars verify successfully, one thing happens:

1 VERIFIED TONNE = 1 dPRN

The dPRN is a byproduct of verification. Not the other way around.
