Slat’s system, alternately, uses the ocean itself as the workhorse, creating what is essentially an autonomous machine. When installed in open water, it functions as an artificial coastline, "catching" the garbage in a V-shaped enclosure as it's pushed along by the ocean's natural currents. The passive system eventually corrals the hordes of floating debris into a concentrated area where it can be easily collected and moved off to shore.
So what happens to all that plastic?
As the trash accumulates in the collection areas, it will need to be hauled off every couple months so it doesn't breach the barriers. To streamline this process, the system is equipped with a solar-powered conveyor belt that slowly feeds the garbage into a giant oil rig-esque bin situated within the collection area, which can be easily emptied by a visiting vessel.
What will they do with all the nasty plastic they pick up? Sell it, duh. Currently, the entire operation relies on sponsorships and donations to keep it up and running, but the ultimate goal is to monetize by selling the extracted plastics back to manufacturers.
