Frequently asked questions.

Seabin is an ocean-health initiative that removes plastic and microplastics from the water and turns what’s captured into real, measured data. Every piece pulled out is counted and catalogued, so the impact isn’t just a feel-good story — it’s numbers you can see.

A Seabin is a floating unit fitted in a harbour or marina. Water is drawn through it, floating litter and microplastics are trapped in a catch bag, and the water flows back out.

It’s where the captured litter goes to be counted and catalogued by hand, category by category — from plastic bottles down to pre-production pellets and microfibres. It’s how a bag of wet litter becomes a dataset.

Seabin is currently operating in Sydney Harbour. We are hoping to expand into other countries and are aiming to be in 100 cities by 2025.

It’s weighed, sorted and analysed in the Ocean Health Lab, then uploaded to a dashboard. Partners can access their impact data on demand, and we publish summaries showing what’s been removed and what it tells us.

Yes. Microplastics make up over half of what we capture at around 55% of all items. This includes micro foam, pre production pellets, microfibres, hard plastic and soft plastic fragments.

We offer partnership packages from entry level up to fully bespoke corporate programs. Each one funds clean-up and gives you the data and assets to show your impact. Get in touch via seabin.io to find the right fit.

Depending on the package: your logo on our site and dashboard, an annual Impact Certificate, data reporting, branded content, and at higher tiers a branded Seabin unit, employee lab-tour days, volunteer days and social campaigns.

These figures are estimates: every catch is weighed on empty acting as a daily data point. Then twice a month, two 24-hour catches per seabin are analysed in our Ocean Health Lab.
