A fleet of self-sustaining vessels will collect and process mixed plastic in the world’s waterways, a nonprofit organization announced this month.

Oceans United, a California-headquartered group, announced it has received a $40 million grant for its marine plastics cleanup effort. The organization plans to design and build a fleet of ships that can each collect up to 50 tons per day of mixed plastic from the oceans.

The ship, called the iCat-90 Skimmer, will then process the plastic onboard and convert it into a fuel using “hybrid hydrothermal liquefaction” technology. The resulting fuel will be used to power the ship, creating what Oceans United calls the “world’s first 100 percent self-sufficient ocean cleaning solution.”

Each 50 tons of plastic will translate to 285 barrels of “high-quality, ultra-low sulfur eco-diesel,” the organization wrote on its website.

The iCat-90 is a 300-foot catamaran. Oceans United plans to begin trial runs in March 2020, and the first iCat-90 Skimmer is scheduled to leave port on April 22, 2020.

Oceans United plans to grow the fleet to five ships by 2024.
