A team of scientists and engineers will on Saturday begin an ambitious cleanup of plastics in the Pacific Ocean targeting a stretch of water three times the size of France known as the Great Pacific Garbage Patch.
A 600m-long floating barrier will be launched off the coast of San Francisco and, powered by currents, waves and wind, will aim to collect five tonnes of plastic debris each month.
The marine apparatus known as System 001 is the brainchild of the Dutch inventor Boyan Slat who founded The Ocean Cleanup at the age of 18 in 2013.
Along with 70 staff he has spent the last five years testing 273 models and six different prototypes as part of the $20m (£15.5m) Netherlands-based project before arriving at the current design – nicknamed “Wilson” in reference to the famous volleyball from the film Castaway.
