TLDR
Seabin and ReSmart have partnered to route plastic waste caught by 21 floating units across Sydney Harbour into recycling streams rather than landfill. Analysed harbour litter will now be collected by ReSmart and sent to specialist recycling partners, closing a loop that previously ended at landfill.
KEY TAKEAWAYS
Twenty-one Seabins deployed across six Sydney Harbour locations have captured an estimated 32.5 million pieces of plastic litter since deployment, according to the organisation's live dashboard.[1] Until now, that material went to landfill after being counted and catalogued in Seabin's onshore Ocean Health Lab.
A new partnership with doorstep recycling platform ReSmart changes what happens next. Once litter is sorted and logged, ReSmart collects it and routes each material type to specialist recycling partners, keeping it out of general waste.[3]
Seabin framed the arrangement plainly in its partnership announcement: catching the plastic is only half the story, and what matters next is where it goes, from ocean to Seabin to ReSmart and back into the loop.[3]
ReSmart, co-founded by Marco Prayer and Giorgio Baracchi in September 2019, has diverted over 2.3 million kilograms of material from landfill across its platform, which handles soft plastics, textiles and e-waste, among other streams.[2] ReSmart has completed 445,000 individual recycling pickups for its customers, with more than 60,000 registered users participating in its doorstep service across Australia.[2]
The platform provides full traceability, meaning each batch of harbour-caught material can be tracked from Seabin to its recycling destination. That traceability is what makes the arrangement worth watching: Seabin's data on what the harbour contains finally connects to a verified disposal outcome.
Seabin's network had filtered 42.7 billion litres of Sydney Harbour water as of September 2026, a figure the organisation publishes via a live public dashboard.[1] Seabin has operated in Sydney Harbour since 2020, each floating unit drawing water through a fine mesh to trap plastics and microplastics before manual sorting onshore. The figures for captured plastic and filtered water come from Seabin's own reporting and have not been independently verified by Bushletter.
