Plastic pollution endangers the oceans

The sea has always been a source of vital energy for humans.

Thanks to the presence of marine plants, the ocean releases more oxygen into the atmosphere than all the world’s forests.

But aquatic pollution is suffocating this ecosystem, with 80% of it coming from land.

Today, there is one piece of plastic waste for five fish.

If we do not act, in 30 years there will be more plastic than fish in the oceans!

Yvan Bourgnon, a committed navigator

The sea, the explorer, fell into it as a child, on a first round-the-world trip that will last three years, with his brother and his parents, at the age of eight.
“At the time, there wasn't all this rubbish. Thirty-five years later, I sailed for two months in the middle of plastics

The "sea gladiator" stops dozens of times a day to clear the debris blocking the boat. When he sets foot on land, his project for a boat called "Manta" to collect plastic in the ocean has already started to mature.

In 2016, he created the association THE SEACLEANERS, dedicated to reducing plastic pollution.

“Our objective is to fight at sea and on land, through corrective and preventive missions. "

The MANTA Project

The MANTA project to clean up the oceans

The Manta, a sea giant with exceptional measurements, is the 1st depolluting, cleaning and recycling boat, with a minimum environmental footprint. It has a pioneering onboard factory for cleaning up the oceans in the world that are the most exposed to plastic pollution.

Its launch is planned for 2024.

Two multipurpose boats – Mobula – will be built into the back of the Manta to supplement the Manta’s collection capacity.

They will enable macrowaste, microwaste and hydrocarbon to be collected in narrower, less deep and less easy to access spaces, where manoeuvrability is limited. The first one will be launched in the 1st half of 2021.

THALGO & THE SEACLEANERS mobilize together

Today, THALGO is mobilizing alongside the association THE SEACLEANERS to clean up the oceans and reduce plastic waste, by acting at 3 levels:

The Manta boat project will collect and recycle plastic macro-waste, before it sinks.

Under the aegis of THE SEACLEANERS, THALGO will increase collection operations to act upstream of ocean pollution.


THALGO & THE SEACLEANERS are mobilizing, with the general public, to change daily habits and reduce plastic waste.
