Industrial solutions for macro-plastics collection & recycling

Stay tunedSupport our POC

Plastic pollution, an environmental tragedy


of plastic wastes are recycled


of plastic wastes are burned


of plastic wastes end up in landfill or environement

million tons of plastics waste ends up in seas every year

85% of plastic wastes at sea comes from land. Plastics are conveyed par rivers to inevitably end up in oceans. With time, under the actions of sun and waves, plastics will fragment up to become microscopic particles. At this stage, they are almost impossible to remove from water. Micro-fragments are being eaten by sea organisms and travel up the food chain up to our own human cells.

Systems & Solutions

Collector anchored in rivers and coastal currents

Collector is anchored in river or estuaries. It will intercept litters brought by currents. It’s operates by local communities and trashs are be processed locally.

Collector towed by local fishing boats


The collector is towed by 2 boats sailing in parralel to maitain the collector open. It’s operates by local communities and trashs are be processed locally.

Ship fitted with collector XXL and recycling machine


A single ship is towing and operating the collector. The ship is fitted with a recycling machine and is able to work in full autonomy. Such ship is usefull to clean specific pollutions after the moonsson, hurricane, tsunami.

Ship fitted with recycling machine


A ship is fitted with a recycling plant and sail from one hot spot to the other to process plastic trashs. The waste are collected by local communities. When the area is cleared, the ship sail to a new location for another campain of cleaning. Such solution is usefull in areas not able to invest in recycling plant.

ReCleanSea success factors

Solutions based on existing tools

ReCleanSea will be developing a super wide collector based on an existing collector that has proven its efficiency over the last 15 years for macro plastic waste and heavy oil recovery.

This existing collector is 18m wide and has been used in ports, bays, towed by small ships or anchored in rivers. The French Navy owns 150 of them as a first line of defense to prevent oil pollution.

Our super wide collector is scaleable thanks to parts that are 100m-wide each, which allows it to reach 500m in width and 700 in length.

An experienced team

Members of our team combine years of professional experience.

Part of the teams have been fishermen operating trawlers in north Atlantic.

Others have conducted seismic surveys with vessels towing immenses camera to image the subsoil of the oceans (camera can be up to 1.5 km wide and 12 km long).

We have experts in plastic recycling. Their missions will be to analyse the oceans plastics we’ll collect and to design recycling processes.


Additionaly, we have in house various type of expertise: layers, computer systems, communication. This allows us to minimize subcontracting costs during the first phases of the project.

Innovative operations

We are heading to operations that have never been done before. Our industrial maritime background and our fishing experience will allow us to imagine and design an efficient collector, and will drive us to innovative ways of operating our tools and processing the collected plastics. We’ll keep thinks as simple as possible because we know that offshore everything is more difficult. We know that our oceans are fragile ecosystems, which nevertheless put human technology under stress.

Development Phases

Phase 1

Design & studies

The first phase consist in the detailed studies and engineering:


  • scalble super wide collector
  • intergation of the collector onboard a ship and operation (for the POC)
  • cleaning, sorting and recycling processes for the marine litters

The studies shall identify hot spot where to test the collector and recycling machines.

Phase 2

Proof Of Concept

The proof of concept is aimed to shake down the collector and the recylcing processes.

To be able to test the collector in full autonomy, we want to utilize a seismic vessel. Such ships are already fitted to handle and to tow big gears like our collector.

Phase 3


The results of the POC will lead to modifications and adjustements of our tools.

We will adapt the collector handling to rivers and coastal current.

We will tune the recycling processes with all material collected at sea during POC.

Phase 4


We’ll run programs to operate our solutions in polluted areas.

The operations will depends on the funding’s we’ll be able to raised, hence the interests of the stakeholders for our tools.

We’ll be there to provide the equipment, to assist in training of operations, or to operate ourselves depending on the needs.

"The ReCleanSea project is the kind of audacious and significant projects we need to help clean-up the oceans. I'm proud to help and advise the Puremar Challenge that's associated with it."
