WATERFRONT AUTONOMY · FROM NORTHERN IRELAND & NORWAY
Building trust
through technology.
NETZERO Alchemists (formerly Clean Sea Solutions) makes marine pollution clean-up safer, smarter, and more efficient, with autonomous hardware and a data platform that proves it.

The real problem
Trust erodes
quietly.
Plastic, microplastics, algae blooms and diesel films accumulate in ports and urban waterways — particularly in low-circulation basins. Manual clean-up is episodic and largely invisible, creating a gap between responsibility and proof.
Citizens complain
Waterfront visibility drives daily perception of the operator.
Tourists share images
One viral photo of debris outlives a hundred press releases.
Regulators ask questions
CSRD, ESRS and Blue Flag scrutiny is now real-time.
Boards feel exposed
Licence-to-operate risk has moved onto the audit agenda.
Cleanliness is a trust, reputation, and licence-to-operate issue.
The Clean Trust Stack
Hardware, autonomy,
and data — one system.
Continuous visible cleanliness plus real-time data that proves compliance, builds confidence, and protects trust.
AQUAPOD®
Dockside collection unit. 24/7 capture of plastics, debris, and oil films.
AQUADRONE
Autonomous sweeper transferring waste to Aquapod, with sonar and surveillance modes.

CLEAN SEA VISION
Real-time reporting platform for compliance and ESG metrics — CSRD & ESRS aligned.



Aquapod®
A silent basin that
cleans the dockside.
Aquapod uses a controlled waterfall to draw floating pollution into a basin, where a removable big-bag captures solids and recyclable absorbants collect oil and diesel film. It balances like a seesaw, regulated by an internal pump.
- 24/7 or periodic waste collection
- Captures microplastics, macroplastics & diesel film
- Integrates into existing dock infrastructure
- Cloud connected, silent operation
- Patented — award-winning innovation
- Microplastic capture down to 1mm
“We collect smaller stuff with the Aquapod than we could do by hand.”
The Waterfall
Naturally attracts waste into Aquapod's basin.
Waste Collection
Removable big-bag; oil captured in recyclable absorbants.
Balancing System
Aquapod balances like a seesaw; flow is pump-controlled.

Aquadrone · Multi-purpose USV
An unmanned vessel that
works the water.
Built in partnership with Maritime Robotics, Aquadrone brings full autonomous mobility to the Clean Trust Stack — sweeping, transferring, deploying booms, and mapping the seabed on the same platform.
“We have a clear ambition to automate as many clean-up operations as possible.”

Protecting Blue Flag standards
at Belfast Harbour Marina.
The first commercial Aquapod® deployment in the United Kingdom — installed inside Belfast Harbour's award-winning Blue Flag marina to move a working harbour from reactive clean-up to continuous environmental stewardship.

The River Lagan carries everything downstream toward the waterfront — urban debris, plastics, industrial runoff, and surface pollution that arrives daily with tide, weather, and river flow. Following the award of Blue Flag Marina status for the third consecutive year, Belfast Harbour installed the Aquapod system to work continuously at the waterline, intercepting floating plastics, debris, microplastics and oil film before accumulation becomes visible.
Paired with Clean Impact View, the deployment gives Belfast Harbour a transparent digital record of environmental activity — aligned to its Clean Tech ambitions, Green Harbour direction, Blueway development and long-term Belfast Harbour 2050 Master Plan.
“People trust clean spaces. Belfast Harbour recognised that maintaining visible environmental standards in a working harbour requires continuous intervention, not occasional response. The Aquapod allows that work to happen quietly, automatically, and consistently at the waterline every day.”
- Floating litter
- Macroplastics
- Microplastics (≥1mm)
- Organic debris
- Surface oil & diesel film
- Leaves & seaweed
Clean water is not simply an environmental issue. It is part of how a city, marina, and harbour are experienced, remembered, and trusted.
From the journal
People Trust
Clean Spaces.
An ongoing series on stewardship, standards, and the quiet discipline behind well-cared-for waterfronts.
Environmental leadership begins where measurement ends.
The environmental sector has become exceptionally good at measuring problems. Water quality in real time. Pollutants to microscopic levels. Currents, tides, dashboards.
Data has never removed a single piece of plastic from the water.
Standing on the pontoon at Belfast Harbour, watching the Aquapod quietly pull water through its intake, the thought keeps returning — somebody still has to do the work.
Stewardship is leadership that continues long after the decision.
There comes a moment in every organisation when a choice has to be made. Wait for the problem to become visible — or quietly prevent it from becoming one.
There are no headlines when water remains clean.
Marina World reported this week on the installation of the United Kingdom's first marina Aquapod at Belfast Harbour. It would have been easy to tell a story about new technology. The more interesting story is about responsibility.
The best work is never seen.
There is a curious truth about places that are well cared for. They seldom announce themselves. Nothing demands attention. Everything simply appears as it should be.
Such impressions are never accidental. They are earned.
Not by one grand endeavour, nor a single day of determined effort, but through the patient repetition of countless small acts — performed with the same care on ordinary Tuesdays as on the day an inspection is expected.
Reputation floats to the surface.
Visitors arrive expecting little more than a pleasant day on the water. Long before a conversation begins, long before they meet the harbour team, they have already reached a conclusion.
They always notice the water.
A report cannot remove a plastic bottle from the water. A dashboard cannot prevent a visitor's first impression. Data may explain the condition of a marina — only action improves it.

Competitive advantage
The only trust
infrastructure for waterfronts.
We compete against niche products — Serial Cleaners, WasteShark, JellyFishBot, Orcauboat — but none combine hardware, autonomy, data, and compliance in a single ecosystem.
Integrated solution
Hardware + autonomy + data platform — not niche point products.
Superior capture
Microplastic capture down to 1mm; oil film absorbed and recycled.
Practical design
Silent operation, >350L capacity, jetty-attachable.
Scalable technology
Cloud-connected, modular, deployable across sites.
Why now
Reputation risk is
real-time.
Social media, live webcams, citizen reporting, and public scrutiny expose pollution instantly. The window for episodic clean-up has closed.
Regulatory push
EU ESG reporting, CSRD, Blue Flag, and sustainability mandates.
First-mover advantage
Scalable autonomous systems with proven port pilots.
Public & stakeholder pressure
Clean spaces are expected, visible, and judged.
