Ocean bound plastic certification answers a question that brands cannot answer on their own: where did this plastic waste actually come from, and can anyone prove it? The scheme, known as OBPC, was developed by the NGO Zero Plastic Oceans together with Control Union and launched on World Oceans Day in 2020. It verifies that plastic litter was collected from environments where it was genuinely at risk of reaching the ocean, and it tracks that material through a certified chain of custody. For buyers facing recycled-content commitments and green-claim scrutiny, understanding how the OBPC program works is now part of basic supplier due diligence.
What Counts as Ocean Bound Plastic
OBP is defined as plastic litter that will be carried away to oceans by the effects of currents, winds, river flows or tides. Around 80% of ocean plastic originates from land-based sources, and much of it is waste abandoned in coastal zones and waterways where rainfall and tides push it seaward. The standard splits collection areas into four categories:
- Potential OBP: within 50 km of a coastline, in regions where waste management is inadequate
- Waterways OBP: rivers and riverbanks
- Shoreline OBP: within 200 m of the high tide line
- Fishing materials OBP: gear and related waste from fishing activity
How the OBPC Program Is Structured
Ocean bound plastic certification runs through two complementary subprograms, because not all collected OBP has commercial value. The OBP Recycling subprogram covers commercially recyclable material: collectors certify origin, and the chain of custody is audited all the way to the final recycled product, which can then carry a verified OBP recycled content claim. The OBP Neutrality subprogram covers material that cannot be sold to recyclers at an attractive price; its collection and correct final treatment are certified, and brands offset plastic footprints through OBP Credits that represent verified collection and treatment. A Social+ component adds requirements for collectors, including fair purchase prices, no child or forced labour and fair wages, verified through annual on-site audits that include interviews with waste pickers.
Chain of Custody: Who Needs Which Certificate
| Role in the chain | Applicable standard | What it covers |
|---|---|---|
| Collection organization | OBP Collection Organization Standard | Certifies origin of collected OBP through to sale |
| Recycling organization | OBP Recycling Organization Standard | Covers processing into flakes or new products |
| Brand or product owner | OBP Brand Standard | Validates on-product and promotional claims |
| Traders | Recycling Organization Standard | Required where clients make certified OBP claims |
| Neutralization services | Neutralization Services Provider Standard | Verifies credits for non-recyclable OBP treatment |
The practical implication for importers: if you buy certified OBP material and resell it under your own claim, you need the right certificate yourself, because a broken chain voids every downstream claim. Reselling already-labelled final products to consumers does not require certification, but promotional use of the logo does.
What Ocean Bound Plastic Certification Does Not Prove
OBPC certification covers origin and traceability, nothing more. It does not certify that the finished product is recyclable or compostable, and it says nothing about mechanical performance, food-contact suitability or migration limits. The phrase "ocean bound plastic" is also not trademarked, so a logo-free claim on a datasheet proves nothing by itself; the only reliable evidence is a current certificate issued through an accredited certification body. Note as well that certified OBP content and GRS recycled content are separate systems, and a buyer can legitimately ask a supplier to satisfy both.
Buyer Checklist for OBP Claims
- Request the certificate number, standard version and issuing certification body
- Confirm the collection category and region match your marketing language
- Ask for transaction certificates that link each shipment to certified volumes
- Distinguish recycled-content claims from OBP Neutral credit-based claims
- Verify social requirements where collection involves informal waste pickers
