The 'Wilson' project aims to collect plastic debris from the Great Pacific Garbage Patch

A giant C-shaped tube aims to collect five tonnes of plastic a month in chunks of 1cm and larger

Driven by wind and waves, the floating barrier overtakes and collects plastic, which is pushed along by currents alone

Every six weeks, a support vessel arrives to collect accumulated debris for recycling

While the float gathers larger chunks, smaller pieces are trapped by an underwater skirt

3-metre skirt allows marine life to pass underneath
