Stolen cooking oil: waste also needs proof of origin

Ninety thousand pounds of valuable waste

A report published on 24 September 2026 says two business operators pleaded guilty, on separate dates earlier in the month, to transporting stolen goods across state lines. According to DOT-OIG, they caused 90,000 pounds of stolen used cooking oil to move from New York to a refinery in Erie, Pennsylvania, in April 2022. The case shows that logistics risk does not end when a product is labelled waste: if it can become biodiesel and be resold, it is already a marketable raw material.

Circularity creates a new chain of custody

Between a restaurant tank and a refinery lie collection, consolidation, storage, transport and receipt. If those steps record only volume and invoice, oil of unknown origin can be mixed into legitimate flows. Every collection should identify the source site, operator, container, quantity, time and destination; every consolidation should preserve the relationship between input batches and the aggregated batch.

Proving origin without exposing the whole operation

A permissioned record can anchor authorisations, weights, seals, documents and custody transfers. Instead of publishing contracts or routes, authorised participants verify hashes, identities, versions and timestamps. This does not prove by itself that the liquid is authentic, but it makes alterations and gaps visible and helps reconcile physical reality with the records.

The passport continues after first use

A Digital Product Passport can follow not only the original product but also its transition into a by-product, waste and secondary raw material. Origin, classification, tests, transformation and circularity claims remain linked to the batch, helping refiners, auditors and buyers distinguish documented material from an input with no provenance.

Across the food ecosystem, clear collection and traceability processes also improve separation between recoverable flows, contaminated material and waste requiring a different destination. FoodSteps applies practical traceability in the food chain. Discover FoodSteps

Five controls for secondary raw materials

• Issue a short-lived, verifiable collection authorisation for each site, operator, vehicle and container.
• Record quantity, time, position and both parties' identities at every custody transfer.
• Maintain batch genealogy when multiple collections are consolidated into a tank or load.
• Use seals, sensors and weight reconciliation to detect opening, diversion or incompatible volume.
• Require proof of origin and transformation history before accepting material or making circularity claims.
