We looked at the Plastiki before when it set sail and now, a few months later the ship has completed its voyage.
The boat, carrying six crew, travelled through a waste-strewn area of the north Pacific and made stops in the Line Islands, Western Samoa and the French territory of New Caledonia before leaving for Australia.
The Plastiki’s bottles are lashed to pontoons and held together with recyclable plastic and glue made from cashew nut husks and sugarcane, while its sails are also made from recycled plastic.
The crew relied on renewable energy including solar panels, wind and propeller turbines and bicycle-powered electricity generators, and used water recycled from urine.
They were able to keep in touch with supporters via satellite through a website, blogs, and use of social-networking sites such as Twitter.
