60% plastic waste are dumped by 3% of coastal populations

Ocean pollution

The growing coastal population the worsening human behaviors do not call for optimism. Plastics dumped in the ocean, mainly from coastal populations, tend to concentrate very quickly in some areas, under the action of currents and natural disasters. Only a collection as close to the source as possible, executed on coastal areas, allow for an effective operation before wastes are dispersed, reduced or join the ocean deepness. With this in mind, Yvan Bourgnon and his team within the association “THE SEA CLEANERS” composed by Patrick Fabre (Founder of the NGO OCEANOPLASTIC), Jerome Vollet (Designer and naval engineer – CEO CONCEPT ESY) and Pierre Guyot (President PressPartner SA) launched a project dedicated to design a revolutionary vessel that will offer the mobility required to get this close to the action and on a timely maner.

For cleaner oceans

Yvan Bourgnon launches "The Sea Cleaners"

He often has during his cruisings, hit unidentified floating objects. In 2015 in particular happened a notable accident: he participated in the Transat Jacques Vabre and his boat collided with a container, forcing him to abandon the race. Faced abruptly with oceanic pollution in this incident but also during his recent world tour in sports catamaran, Yvan Bourgnon decided to take action. With the creation of the association “THE SEA CLEANERS” dedicated to the fight against oceanic pollution, he began building a revolutionary ship “THE MANTA” a collector of plastic waste. A crowdfunding campaign, which is starting on 14 October, marks the beginning of this adventure.

“Between 8 and 10 million tons of plastic are dumped into the oceans each year. Some of these floating macro-waste are fragmented when in contact with waves, then UV rays to turn those wastes into micro-waste and nano-waste, assimilated by marine organisms, impacting the entire marine food chain. By 2025, the amount of plastic waste entering the marine environment could be multiplied by 10. At this rate, in 2050, the pieces of plastic found in the oceans will be as numerous as the fishes! “

For cleaner oceans


The MANTA is named after the manta ray for its ability to filter the water. This vessel is designed to collect oceanic plastic at its closest to the spill source, near the coast. Indeed, only a ship provides the mobility required to execute quick trips to the plastic benches while they are still concentrated by the winds and currents before they begin their ocean drifts towards “plastic continent”. This mobility also enables intervention on the high seas, where the ocean depth makes anchoring impossible in case a submerged container may have accidentally discharged its cargo of plastic objects. In terms of propulsion, the use of Wing Kite (kite) combined with a rigging system supporting conventional sails, plus a hybrid power unit, will ensure to reduce the carbon footprint to an absolute minimum.

A never seen before collection system

A unique ramp collection, nearly 72m wide, will collect macro-waste with no risk of harming aquatic wildlife. This biomimetic system inspired by whale baleen is designed to be foldable to cross main channels (including Panama) and access zones close to ports. On board, a treadmill will route macro-waste to storage tanks. The Manta can store in its tanks up to 300m3 of plastics, collect campaigns will last from several days to several weeks. An electronic device noise emission allow the removal of marine life at the approach of the ship, to avoid bycatch.

Collecting data is essential for analysis of the phenomenon

All collections will be geotagged, monitored, and analyzed before being sent to recycling centers. The data will be formalized on board and then transmitted to the international scientific community. It will help the scientific community calibrate the first observations made offshore and other data produced by sampling in oceanic gyres.
