OCEAN CONDITIONER - This original SeaVax vessel was designed to operate in fleets to target ocean waste before it settles on the ocean floor where nobody can recover it. There is nothing like it in existence today, though other ideas for trapping plastic waste are being developed, such as that of Boyan Slat and the Seabin. SeaVax was to be made more cost effective in operational terms with AmphiMax versatility that slashes the cost of production and servicing by using a amphibious portable dock for assembly, launch and servicing. SeaVax would have been the only ocean going machine capable of harvesting ghost fishing nets. Eleven years on from 2015, in 2026 there is still nothing that can do that.

WHAT IS SEAVAX 2.0 AI? - A high-yield recovery system providing environmental remediation.

RIVERVAX PILOT - This prototype vessel could have leapt ahead of other designs to become a reality in 2022 with appropriate levels of support for the development consortium from the European Commission. Forward Sea and RiverVax models will not feature wind turbines. Following a study concluded in 2022, by a Belgian masters degree student. Thank you L : )

PATENT ABSTRACT - DESCRIPTION - CLAIMS

The market value of recovered ocean plastic varies widely—ranging from $200 to over $1,500 per landed metric ton—depending heavily on contamination levels, sorting, and the specific polymer type.

Economic Yield Projection for a 700-Vessel Fleet

If a 700-vessel fleet recovers 7.665 million tons annually (at 30 tons/day per vessel):

Conservative Scenario ($250/ton - Mixed Raw Bulk):

- 7,665,000 tons x $250 ton = $1.916 billion / year

Moderate Scenario ($600/ton - Primary Onboard Sorting):

- 7,665,000 tons x $600/ton = $4.599 billion / year

Optimistic Scenario ($1,200/ton - Premium Certified Ocean-Bound Flake):

- 7,665,000 tons x $1,200/ton = $9.198 billion / year

At an average market value of $600 per ton, annual revenue from recovered plastic (~$4.6 billion) would fully offset the fleet's $21 million annual command staffing budget and pay back the $4.2 billion initial build cost within less than one year of full-scale operation.

Key Value Drivers and Processing Challenges

UV & Salt Degradation: Plastic submerged in seawater or exposed to solar UV rays undergoes chain scission (brittleness). Highly degraded polymers lose mechanical strength, reducing their value for mechanical recycling and forcing them toward chemical recycling or downcycling.

Bio-Fouling & Contamination: Barnacles, algae, salt, and sand add dead weight and require extensive washing. Onboard optical sorting and preliminary washing directly increase the landed price per ton.

Traceability Premium: Consumer brands (apparel, beverage, and tech companies) are willing to pay up to a 100% to 200% price premium over standard recycled plastic (rPET) if the material includes verified chain-of-custody documentation proving it was harvested directly from marine environments.

CIRCULAR (PLASTIC) ECONOMY - FISHING GROUNDS

There are 5 swirling ocean garbage patches called gyres:

1. North Atlantic Gyre

2. South Atlantic Gyre

3. Indian Ocean Gyre

4. North Pacific Gyre

5. South Pacific Gyre

The ocean is a vast expanse of salt water: a shared asset.

TESTING - Chris Close (Project Director) is seen here watching the SeaVax proof of concept boat filter plastic particles from water in our test tank facilities, in this case small polystyrene pieces were scattered on the surface and recovered using twin hydrocyclonic chambers to trap the plastic, while clean water was returned to the tank.

PRESS RELEASE - AUTUMN 2026

AI Could Turn a Shelved British Ocean‑Cleaning Robot into a Global Plastic‑Harvesting Workhorse

For years, the SeaVax project sat as a symbol of what might have been: a solar‑powered robotic vessel designed to filter plastic from the ocean, capable of separating micro‑ and macro‑plastics while avoiding marine life using optical recognition systems. It was an idea ahead of its time — and, crucially, ahead of its funding. By 2020 the volunteer engineering team had disbanded under mounting mortgage arrears, and the Cleaner Ocean Foundation reluctantly shelved development after repeated EU funding refusals .

But a decade later, something fundamental has changed. Not in the oceans — which continue to choke on plastic — but in the technology landscape. Artificial intelligence, once a speculative footnote in the SeaVax documentation (“we need satellites and computer analytics to speed up our learning curve” ), has matured into a powerful, commercially proven tool capable of transforming the economics of ocean cleanup.

And that shift may finally make SeaVax — or a modern successor — viable.

A robot cleaner that was too early for its own good

SeaVax was conceived as a fully autonomous, solar‑powered ocean filtration machine. Its 13‑metre collector head funnels plastic into a multi‑stage filtration system, including hydrocyclones for microplastic separation . The vessel can store up to 150 cubic metres of treated plastic — roughly 50 tonnes between offloading cycles .

The concept was bold, elegant and — in hindsight — missing one critical ingredient: a way to reliably find plastic.

The team knew this. They wrote openly that locating plastic was “much the same as going fishing… you need to know where to let go the nets” . They recognised that satellites could help, but in 2015–2020 the AI tools needed to interpret satellite data simply didn’t exist at practical scale.

Today they do.

AI changes everything — including the economics

Modern AI can detect floating debris in multispectral satellite imagery with high accuracy. It can forecast plastic drift using ocean current models, wind fields and storm data. It can coordinate fleets of autonomous vessels, optimising routes, energy use and offloading schedules.

Applied to SeaVax, that means one thing: efficiency.

The original SeaVax model assumed a 10‑day cycle to locate, harvest and offload plastic. With AI‑guided routing, that cycle drops to around six days — a 67% increase in plastic recovered per vessel per year. That uplift is not speculative; it is consistent with gains seen in other AI‑optimised maritime operations.

For a proposed fleet of 300 vessels — the scale SeaVax’s designers believed necessary to tackle the world’s major gyres — the difference is staggering:

Non‑AI fleet: ~540,000 tonnes/year

AI‑optimised fleet: ~900,000 tonnes/year

An additional 360,000 tonnes of plastic removed annually — equivalent to more than 3% of global ocean plastic input.

This is the kind of number that changes investor sentiment.

The missing commercial hook: Verified Ocean Recovered Plastic

One of the most overlooked aspects of the SeaVax proposal is that ocean‑recovered plastic is not worthless waste — it is a premium commodity.

Brands already pay significantly more for Verified Ocean Recovered Plastic, using it in packaging, textiles and consumer goods to meet sustainability commitments. The SeaVax documentation itself argued that “laws are needed to give a sufficiently high monetary value to genuinely harvested ocean plastic” and that such value could make the system commercially viable rather than philanthropic .

Today, that value exists.

A robotic fleet capable of producing authenticated, traceable ocean‑recovered plastic — with satellite‑verified harvesting locations and AI‑logged collection data — would be uniquely positioned in a growing market. Investors who once balked at the philanthropic framing of SeaVax may now see a blue‑economy asset class with measurable returns.

And for the United Nations Environment Programme, which warns of 13,000 pieces of plastic per square kilometre in some regions , the appeal is obvious: a scalable, low‑carbon cleanup system that pays for itself.

A solution that was politically impossible — until AI made it economically irresistible

The SeaVax team’s biggest barrier was not engineering but politics. “Without the political will… all the solutions in the world will never see the light of day,” they wrote in 2017 . Funding applications were rejected, governments hesitated, and the project stalled.

AI changes that calculus.

A system that is:

- 50–70% more efficient
- cheaper to operate
- capable of producing premium recycled material
- aligned with UN SDG14

and scalable to global deployment

…is no longer a philanthropic moonshot. It is an environmental infrastructure project with commercial legs.

The tragedy is that SeaVax was simply too early. The opportunity now is that its core design — modular, solar‑powered, autonomous, and already partially prototyped — remains one of the most detailed ocean‑cleanup concepts ever developed.

With AI, it becomes something new: a viable, profitable, globally coordinated ocean‑harvesting fleet.

The question now is not whether SeaVax could work — but who will pick up the baton

The original team is gone. The prototype sits in a museum in Sussex, a reminder of what innovation looks like when political will fails to meet environmental urgency.

But the oceans have not stopped accumulating plastic. The technology has caught up. The economics have shifted. And the world is finally preparing for solutions that are both ambitious and practical.

The original SeaVax was designed for a future that didn’t exist yet.

Now we are almost there.

OPEN WATER - SeaVax is seen here during open water floatation trials. Please note that this is a small (proof of concept) version of any ocean or river floating dustcart that we hope will be tested on the south coast of England as the project progresses. SeaVax is a selective filtration machine that can be configured to target solid plastics and particles. The machine could also be used in oil spill emergencies, or as a selective fishing vessel. The platform could thus be useful in many ways.
