The Plastiki is a handmade 20m catamaran constructed entirely out of reclaimed plastic PET bottles. It took two years to design and build and the crew sailed out of San Francisco on 20 March, arriving in Sydney on 26 July.
The Plastiki's mission is to promote a better understanding of ecological issues, primarily plastic waste management and renewable energy. The Plastiki itself is constructed out of a mono-polymer material that has been created out of melted plastic PET bottles. The material started off being fabric-like and through heating and pressure processes was eventually made into a fibre comparable to fibreglass but much tougher. Unlike fibreglass, the plastic bottle-based material won't break under pressure, but will instead expand.
