The foundation was established four years ago in the Netherlands by entrepreneur Boyan Slat, who was 18 at the time. It currently employs nearly 65 engineers and researchers working on advanced technologies to tackle the problem of extreme plastic pollution of the world's oceans.
The latest investment pushes The Ocean Cleanup's total amount raised since 2013 to $31.5 million. Most of this significant contribution consists of donations from San Francisco-based philanthropists Marc and Lynne Benioff and an anonymous donor.
The money will be used to launch the first experimental cleanup system in the Pacific Ocean later this year. It will represent the most significant milestone on the road to the full-scale cleanup of the world's oceans.
"Our mission is to rid the world's oceans of plastic, and this support is a major leap forward towards achieving this goal," Slat said in a statement.
"Thanks to the generous support of these funders, the day we'll be returning that first batch of plastic to shore is now in sight."
Last fall, The Ocean Cleanup found 1,000 large bits of plastic in two hours during their first aerial reconnaissance mission over the Pacific Ocean.
