To tackle today’s environmental challenges, we draw on science and our 1,300 experts. And to develop practical solutions that closely match local needs, we work with local authorities, industry, academia, the social and solidarity economy (SSE) and start-ups to build virtuous ecosystems that create shared value.

Creating local synergies to accelerate the circular economy

Since 2022, together with the Greater Montauban Urban Community (France), we have been leading a coalition of SSE stakeholders around an ambitious performance contract.
The aim is to reduce waste volumes by 10% over seven years by implementing a circular and inclusive economy.

Among the flagship projects is a new-generation waste collection centre – a veritable “reverse supermarket” – which combines waste collection services, a resource centre, a repair workshop, and the sale of composters, second-hand bicycles and reusable materials.

In addition, 12 services, such as home garden waste shredding and the installation of compost bins on request, improve local waste recovery. The initiative supports 117 direct and indirect jobs among partners and generates over 52,000 hours of work integration each year.

Building scientific partnerships to drive environmental innovation

Over the last 10 years, together with the CNRS, one of the world’s leading research organisations, we have collaborated on more than 30 projects and hold a portfolio of 14 joint patents.

Our teams and researchers from the ICMCB(1), the CNRS laboratory specialising in supercritical fluids, have notably co-developed a pilot hydrothermal gasification unit.

This innovative process makes it possible to treat liquid or wet organic waste by recovering the resources they contain, producing renewable gas while destroying pollutants.

The new framework agreement signed in 2025 reinforces the pooling of our innovation capabilities and the CNRS’s scientific excellence over the next five years.

Working together with public and private sector stakeholders to ensure access to water

We have been supporting Senegal in its water and sanitation management for over 20 years.

In 2020, the collaboration took on a new dimension with the creation of SEN’EAU, a company incorporated under Senegalese law that we established with the State of Senegal.

It provides access to water for 10 million people with tangible benefits. Across the entire area managed by SEN’EAU, water is supplied 24 hours a day in urban and peri-urban areas, with a quality that meets WHO standards. In particular, 98% of Dakar’s residents have a continuous water supply. Network modelling has enabled all residents of Dakar to benefit from a new water supply of 200,000 m3 per day mobilised by the State.

 

Today, 93% of consumers place their trust in SEN’EAU. In 2025, the United Nations Economic Commission awarded its first prize to SEN’EAU as a successful example of a Public-Private Partnership. The involvement of the State of Senegal and our expertise in the water sector within SEN’EAU have contributed to this success.

And also... our impact seen by

At SUEZ, we firmly believe that waste is not simply rubbish but a resource. We support our corporate and industrial clients across a wide range of sectors – retail, healthcare, printing, the automative sector, energy and heavy industry – in the comprehensive management of their waste. Drawing on our culture of innovation and our partnership-based approach, we work with each client to develop bespoke solutions tailored to their operational constraints and challenges. Our ambition is clear: to ensure that every type of waste finds it way to recovery, whether as material (cardboard, packaging, copper, steel, aluminium, wood, etc.) or energy (heat, electricity, etc.), to accelerate our clients’ environmental transition.
