Protect the oceans

The oceans are essential for life and play a major role in mitigating climate change. Yet over-fishing, rising temperatures and pollution threaten them. As an expert in the water and waste sectors, SUEZ makes the commitment to protect them in the new Sustainable Development 2017-2021 Road Map.


The oceans, a now endangered resource essential to life

97 %

of the planet's water resources come from the oceans

50 % and more

of the oxygen on earth is provided by the sea

80 %

of marine pollution is a result of human activity

260,000 t

of plastic floating in the oceans

Our commitment

Use SUEZ's solutions to protect the oceans

Preserving the oceans is a major commitment which is included in the new 2017-2021 Sustainable Development Road Map. Located at the crossroads of water and waste challenges, SUEZ today uses its expertise to serve local public policies that limit pollution of the marine environment by human activity. Thanks to its overall vision, SUEZ can supply its customers with tangible solutions that limit terrestrial sources of pollution by changing the conception of the waste life cycle to a more circular model and by making the cities’ water networks intelligent.
  • Its expertise in water and plastic waste treatment to develop solutions to reduce pollution that originates on land
  • A comprehensive logistics network as a result of its presence in numerous regions in and outside France
  • Constantly evolving solutions thanks to its innovativeness and research network
Our actions

Support the initiatives of associations involved in protecting the oceans

With scientific expeditions

The Group works alongside the associations Expédition 7ème Continent and Expédition MED. Through expeditions, the former in the Pacific and Atlantic oceans and the latter in the Mediterranean Sea, the objective is to study the scope of plastic pollution in the oceans, secure media coverage of the phenomenon to alert the international community and launch concrete initiatives.


With Good Planet

SUEZ also partners with Good Planet, dedicated to combating threats to the oceans through awareness initiatives such as beach clean-ups and the creation of awareness-rising materials and encourage community involvement.

"It is by coming together that we will be able to find areas of improvement and develop effective solutions. It is high time that we understand, explain and act"

And since 2015, SUEZ has also been committed to UNESCO’s intergovernmental oceanographic commission with the goal of implementing tangible solutions that help bringing an end to ocean pollution.
Our mobilization

A global campaign for the collection of waste

On the occasion of the World Oceans Day, June the 8th, SUEZ launches a worldwide mobilization campaign, named #SUEZ4ocean, towards its 84,000 employees. The Group invites them to gather as many people as possible to organize cleaning operations of plastic waste on shorelines and in catchment areas.

Our solutions

Our solutions to regenerate the coastline and preserve the oceans

SUEZ offers solutions to control water quality, limit pollution sources and protect and restore coastlines. There are a few examples :

Fighting water pollution involving micro-plastics

While treatment plants represent a barrier to water pollution, certain types of pollutants are able to get through traditional filtration system. This is the case with the microfibers used in our clothes. This is the reason why SUEZ, which operates the purification station at Nice-Haliotis, has teamed up with the Nice Côte d’Azur city authorities, the MED Expédition NGO and the Villefranche oceanographic laboratory to launch Ecoseastem, the first ever research program that looks into pollution by microfibers. 
The aim of the programme is to characterize the pollution caused by plastic microfibers, to assess the impacts of this pollution on the natural ecosystem and to identify the best available technologies to treat this type of pollution, such as dynamic microfiltration.

Control bathing water

In Barcelona (Spain), the municipality installed the COWAMA water quality monitoring system along the city's beaches. This control system is used to identify the main sources of pollution in real time and therefore anticipate water quality along the beaches. Using the iBeach app, this information on bathing water can be sent to citizens who can also see the water temperature, flag colour, UVA radiation level and even whether jellyfish are present.

Pollution control barrier to restore coastlines

The coastline of Casablanca (Morocco) is one of the most industrialized in the country, generating pollution mainly linked to discharges of raw sewage into the sea. SUEZ provided the city with assistance in building the new pollution control system, which is now used to treat all of the city's sewage, in addition to the system implemented in the western part of the city. 24 kilometres of coastline are now protected and the beaches have been returned to the residents.

Collect plastic bottles

80% to 90% of the plastic found in the oceans is made of polyethylene, a type of plastic frequently used for packaging. To prevent this waste from ending up in the sea, supermarkets in Argelès-sur-Mer (France) have been transformed into collection centers thanks to the Reco solution. Residents are invited to drop off their plastic bottles and containers in the car park of their local store in exchange for vouchers. The containers are then sorted and recycled to give them a second life. It is a great circular economy initiative that has already been adopted by more than 50 stores in France.
