In the article “Boy Genius Boyan Slat’s Giant Ocean Cleanup Machine is Real,” Schiller (2017) stated that an improvised design of the trash collecting machine would help to collect plastic trash in the Pacific Ocean.
• The Great
Pacific Garbage Patch is an area of the ocean where currents concentrate the
plastic we throw into the ocean.
• Boyan
Slat, who first set out a vision of his Ocean Cleanup machine in a TED talk six
years ago when he was just 17, announced that he’ll begin hauling trash from
the Patch in 2018.
• Slat’s
design involves massive booms that collect trash using the Pacific’s own
currents.
• The booms
act as an “artificial coastline” passively catching and then concentrating
debris into the centre, from where it’s offloaded to a boat that sweeps by
periodically.
• He plans
to suspend the booms with large anchors that float in deeper water, so the
booms shift around the ocean.
• The
anchors will be suspended on lines in four segments, each 40 feet tall and 13
feet wide.
• They have
a total surface area of 328 feet square, enough to provide plenty of drag to
slow down the booms as plastic trash circulates around the “gyre”–a swirling
trash vortex within the Garbage Patch.
• Using a
floating system has advantages in both cost and time.
• The Ocean
Cleanup Foundation, now numbering 65 people, will begin testing a 0.6-mile
prototype, before full deployment in 2018.
• Slat
expects to collect tens of thousands of tons of debris a year, and for each
device to need emptying every month.
• The
long-term plan is to recycle all the plastic collected into items like car
bumpers, chairs, and eyewear.
