For several decades now, plastic has totally invaded our lives with more than 400 million tons produced every year.

This massive plastic production, which is not slowing down, leads to pollution of the marine environment with the diffusion of waste in rivers, seas and oceans.

If we do not succeed in controlling this plastic pollution with innovative solutions, the UN predicts that by 2050 there will be more waste than fish in our oceans.

Every minute, 19 tons of plastic spills into the sea.


According to the Ramoge Agreement (environmental protection treaty signed in 1976 between France, Monaco and Italy against pollution of the marine environment), a macro-waste is defined as “a solid waste of human origin, visible to the naked eye which, when abandoned, is visible on the coast, is floating on the surface or is lying submerged”.

These wastes are mainly carried by rivers, sea currents and wind. Then, they accumulate at sea, are ingested by wildlife or wash up on beaches. The impacts of this pollution are multiple: environmental, socio-economic and sanitary.


Microplastics – plastic particles less than 5mm in size – mainly come from macro-waste dumped into the oceans and reduced in size by currents or friction on rocks or sand.

These microplastics proliferate in the marine environment until they are ingested by marine wildlife and end up on our plates when we eat contaminated food!

In order to fight against this global emergency, actions should be taken by the different stakeholders (awareness raising, implementation of local actions, recycling …).

Innovative solutions for the fight against pollution

Efinor Sea Cleaner is involved in the fight against marine pollution in the broadest sense of the term through its multi-service clean-up vessels. Each boat is provided with a unique patented technology that allows the recovery of all types of floating solid or liquid waste.

Depending on their application, they are able to control the spread of macro-waste by acting as close as possible to human activity, but also to reduce existing pollution (macro-waste and microplastics) in the seas and oceans.

At the same time, the company is continuing its efforts in R&D for new solutions and technologies adapted to new environmental constraints, in particular:

  • To support the deployment of more eco-friendly and “CO2 free” engines (cf. Waste Cleaner 66E and ongoing development of a larger version).
  • Through the Sargasse project. Current work with Ademe and several French / international research organizations to develop a vessel specialized in collecting Sargasso seaweeds before they reach our coasts. To promote the possibilities of downstream recovery (without sand) but also to avoid any risk of human contamination by toxic gases emitted during decomposition.
  • Through a co-development with the association The Sea Cleaners, based on the technology of our existing vessels, of vessels ensuring the recovery of microplastics and macro-waste in support of MANTA.
