Sheltered harbour water at a working waterfront

MARINAS · HARBOURS · WATERFRONTS

Keep your water clean.
And prove the difference you're making.

Floating rubbish, plastics, oils and other pollution don't stop arriving when your team stops cleaning.

NETZERO Alchemists helps you continuously remove pollution from the water, reduce the burden of manual clean-up and provide evidence of the environmental impact you're making.

The problem

Pollution doesn't arrive
to your cleaning schedule.

Floating plastics, litter, oils and other pollution naturally collect around pontoons, corners, berths and areas of sheltered water.

Your team cleans it.

Then it comes back.

And somebody has to deal with it again.

There is a better way to keep on top of it.

The outcome

Keep it clean. Without creating
another job for your team.

NETZERO Alchemists helps continuously intercept floating pollution where it naturally accumulates, keeping water cleaner between manual interventions and reducing the repetitive burden on your team.

01

Cleaner water

Continuous collection where floating pollution accumulates.

02

Less repetitive clean-up

Reduce the need to repeatedly send people out to deal with the same problem.

03

Continuous intervention

Pollution can be intercepted while your team gets on with running the marina or harbour.

Aquapod®

Continuous pollution interception
where you need it most.

Aquapod is installed where floating pollution naturally accumulates. It continuously draws floating material from the surrounding water and captures it for removal, helping keep problem areas cleaner without relying entirely on repeated manual clean-up.

A controlled waterfall draws floating pollution into the basin, where a removable big-bag holds solids and recyclable absorbants collect oil and diesel film. The unit 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.”
Frans Bakker — Managing Director, ASVZ, Rotterdam

In practice

Built for the people
who have to operate it.

A pollution solution only works if it also works for the people responsible for the harbour or marina. From installation and operation to emptying, maintenance and monitoring, our focus is making continuous pollution interception as straightforward as possible for the team using it.

  1. 01

    Install

    Fitted to existing jetty or pontoon infrastructure at the accumulation point.

  2. 02

    Operate

    The unit runs continuously or on a set pattern, drawing in floating material.

  3. 03

    Empty

    The big-bag lifts out; oil absorbants are replaced and recycled.

  4. 04

    Reset

    The unit is returned to operation by the harbour or marina team.

  5. 05

    Monitor

    Activity is visible remotely through Clean Impact View.

Aquapod is emptied, maintained and serviced by people. It is designed to reduce repetitive manual clean-up rather than remove the need for a team.

Belfast Harbour · Live deployment

Proven in a
working harbour.

NETZERO Alchemists is already working in Belfast Harbour, where Aquapod has been deployed in a live harbour environment to continuously intercept floating pollution.

The River Lagan carries urban debris, plastics and surface pollution downstream toward the waterfront with tide, weather and river flow. It gathers in the sheltered water of the marina. Aquapod works continuously at the waterline there, intercepting floating plastics, debris, microplastics and oil film so that accumulation is dealt with as it arrives.

Paired with Clean Impact View, the deployment gives the harbour team a record of the environmental activity taking place, relevant to Belfast Harbour's Clean Tech ambitions, Green Harbour direction, Blueway development and long-term 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.”
Alan Branagh — Founder & Director, NETZERO Alchemists

Clean Impact View

Don't just clean it.
Prove it.

Removing pollution matters. Being able to show what is happening and the action you're taking matters too. Clean Impact View helps turn environmental activity into evidence.

Remove it · Measure it · Evidence it

Collected material is recorded and classified, water volume drawn through the unit is tracked, and activity is timestamped so a marina or harbour team can understand what has been removed and demonstrate it to others. Reporting is aligned to EU CSRD and ESRS pollution disclosures.

Environmental standards

Environmental standards have to be
maintained every day.

For marina and harbour operators, environmental standards are not something that matter only on assessment day. Visible pollution, environmental action and evidence are ongoing responsibilities.

NETZERO Alchemists can support practical environmental activity relevant to areas within the Blue Flag Marina framework.

See our Blue Flag alignment

Supporting activity relevant to a criterion

Continuous interception of floating pollution and a record of that activity can support the environmental work behind a criterion.

Formal compliance with a criterion

Compliance is determined by the operator and the assessing body, not by the equipment installed.

Blue Flag accreditation

Accreditation is awarded to the marina or beach operator through the national Blue Flag process.

FEE endorsement

NETZERO Alchemists holds no endorsement from Blue Flag or the Foundation for Environmental Education.

Installing an Aquapod does not in itself satisfy a Blue Flag criterion.

The NZA system

One problem.
A connected response.

Three parts of the same response, used together or on their own. Your water and your problem determine what is appropriate.

CLEAN IMPACT VIEW

Does this sound familiar

When keeping on top of the water
becomes a problem.

01

Pollution keeps collecting in the same place

Floating waste repeatedly gathers around pontoons, berths, corners or sheltered areas.

02

Your team keeps having to clean it

The same manual intervention has to happen again and again.

03

An incident has created an ongoing recovery problem

Pollution needs to be intercepted rather than repeatedly chased after it disperses.

04

Environmental standards matter

You need practical action and evidence of what is being done.

05

People can see the problem

Visitors, customers, tenants, stakeholders and the wider public can see the condition of the water.

The tide never stops.

The water does not pause for weekends, inspections, or the end of a shift. It keeps moving, and with every movement it carries whatever has fallen into it.

The tide does not reset. Neither can the work that keeps water clean.

A marina, a harbour, a waterfront — these are living systems, not static scenes. The tide delivers, the current re-arranges, and the task of keeping the water clean begins again with every turn of the cycle. That is the case for continuous, autonomous collection: not to replace people, but to stand watch when the team cannot.

The pressure of keeping your Blue Flag.

A Blue Flag is awarded in a single moment. It is defended every day of the season. Water quality, cleanliness, safety — all judged against standards that never relax.

The award is won once. The standard is kept daily.

For marinas and beaches, the hardest part is not the assessment — it is the quiet, continuous work between assessments. Autonomous collection and verified data turn that pressure into evidence you can hand over with confidence.

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, rather 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.
