American engineers are deploying a rubbish collection device to corral plastic litter floating between California and Hawaii in an attempt to clean up the world's largest garbage patch in the heart of the Pacific Ocean.

The 600-metre long floating boom is being towed from San Francisco to the 'Great Pacific Garbage Patch' - an island of trash five times the size of Victoria, Australia.

The system was created by The Ocean Cleanup, an organisation founded by Boyan Slat, a 24-year-old innovator from the Netherlands who first became passionate about cleaning the oceans when he went scuba diving at age 16 in the Mediterranean Sea and saw more plastic bags than fish.
