In 2010 environmentalist David de Rothschild sailed from San Francisco to Sydney in 'The Plastiki' , a unique 18.3-metre catamaran made from approximately 12,500 reclaimed plastic soft drink bottles, sails of recycled PET, and masts made from aluminium irrigation piping and consist of 98 per cent post-consumer billet. In his talk for Sydney Ideas, with inventor, educator and adjudicator Sally Dominguez, David de Rothschild explained the technology used on board and revealed what he and crew learnt on their four-month journey about plastic in our oceans.
