The Ocean Cleanup is a project initiated by 23 year old Boyan Slat from Delft (NL). When he started the project he was only 20 years old. Their crowdfunding campaign was able to raise $2 million from more than 40.000 supporters. Maybe you where one of them?
Additionally the project received $31 million from sponsors including chief executive Marc Benioff, philantrophist Peter Thiel, and the Julius Baer Foundation.
The concept for cleaning up the oceans consists of 50km long V-formed tubes, which are floating on the surface of the sea, kept in place by weighting. They´ll collect 90% of the plastic debris floating in the oceans with a size bigger than 20mm. The waste will bring them around 50 Euros per ton of plastic debris brought to recycling stations. Most of the plastic debris is floating withing 3 meteres below the surface of the sea.
