Environmental consultancy and contract manager Helistrat has installed two Seabins in marinas run by Premier Marinas, at Port Solent and Gosport, to help tackle marine plastic waste and raise the profile of the Seabin Project.
Seabins are floating rubbish bins which are located in the water at marinas, docks, yacht clubs and commercial ports. Each bin can collect up to half a tonne a year of floating debris including microplastics as small as 2mm.
A submersible water pump, capable of displacing 25 litres an hour, sucks water in from the surface. This passes through a catch bag inside the Seabin and is then pumped back into the marina leaving litter and debris trapped inside.
The Seabins are emptied twice a day by Premier Marinas.
On retrieval from the water, material from the catch bags is sorted to extract recyclable materials, including plastics, which are sent to reprocessors. Non-recyclable material is used to offset fossil fuels in the production of energy.
