As a trusted partner for circular solutions, we leverage our expertise across the entire waste lifecycle.
We provide you with operational solutions to guarantee responsible management, recycling and recovery of waste, while minimising your environmental impact.
We support you in managing your EfW facilities, optimising the return on the assets entrusted to you. Thanks to a personalised approach and rigorous management, we ensure maximum energy performance and sustainable value for investments.
Are you a local authority concerned about the environment and energy efficiency? Are you seeking innovative solutions to manage your waste responsibly while producing energy?
Thanks to our expertise, we support you in your planning and advise you on each stage of the value chain of your waste disposal plant, from construction to the recovery of by-products (incinerator bottom ashes), including operation. By optimising the use of your EfW plants, we transform your waste into local and sustainable energy.
Within an EfW plant, non-recyclable waste is incinerated in a furnace. The heat generated by combustion is used to heat water and produce steam. This steam powers turbines to generate electricity. Additionally, the heat is introduced into district heating networks or industrial heating networks.
We are also involved in the production of hydrogen from non-recyclable waste as part of the energy transition of the territories.
A major example: H2 Créteil, the largest hydrogen production and distribution station in France
This station, inaugurated on September 23rd, 2025, will soon be able to produce one ton of hydrogen per day from the electricity that we will supply as part of the operation of the Créteil EfW plant (Valomarne) of the Val-de-Marne Joint Urban Waste Treatment Association (SMITDUVM). The electricity is produced by the fermentable fraction of household waste collected in the 19 municipalities of the SMITDUVM.
In 2023, we developed a sustainable development roadmap to structure our actions around a shared ambition in the fight against climate change, the preservation of biodiversity and social responsibility.
With this ambition, we have developed innovative for construction projects and the operation of EfW plants using an integrated approach that optimises recovery of resources while reducing the ecological footprint.
Thanks to our technical and operational expertise as well as our ability to innovate, we transform waste into valuable resources, contributing to the preservation of our planet for future generations.
The Créteil Energy-from-Waste plant, led by SUEZ and TIRU, embodies an innovative circular economy model in the Île-de-France region. Designed to treat 345,000 tons of waste per year, this project produces electricity, district heat, hydrogen for vehicles, and captures CO₂ thanks to microalgae.
A 4,500 m² urban agricultural greenhouse heated by the EfW will provide tomatoes in a short circuit, contributing to local integration.
This project focuses on sustainability, employment and ecological awareness.
An Energy-from-Waste plant (EfW) is an industrial facility where waste is incinerated to produce energy. This type of installation makes it possible to transform non-recyclable waste into electricity, heat or steam, thus reducing its volume and environmental impact.
The waste is collected and transported to the EfW plant, where it is incinerated in a furnace. The heat produced by this combustion is used to heat water and produce steam. This steam drives turbines that generate electricity. Additionally, the heat can supply a district heating network or an industrial heating network.
Incineration is a waste treatment process that involves burning waste at high temperatures to reduce it to ashes. This process reduces the volume of waste and recovers the energy produced during combustion to produce electricity and/or heat.
Bottom ashes are the non-combustible solid residues that remain after the incineration of waste in an Energy-from-Waste plant (EfW). It consists of the mineral part of the burned waste, including metals and inert materials that do not volatilise during the combustion process.
Fly ashes are by-products generated by the flue gas treatment process in household waste incineration plants. These residues consist mainly of fly ash, flue gas reaction products with process reagents, and other particles and pollutants captured by filtration systems.
The circular economy is an economic model that aims to minimise waste and maximise the reuse of resources. The circular economy focuses on the closed loop of materials and products, aiming to create a continuous cycle of reuse.
Biomass refers to all organic matter of plant or animal origin, which can be used as a source of energy. It includes various materials such as:
An urban or industrial heating network is a system for distributing thermal energy in the form of heat (and sometimes cold) through a network of pipes, often buried, connecting one or more sources of heat production to public buildings (town hall, schools), residential, commercial or industrial buildings.
Recovered heat (or waste heat) is the heat generated by a process whose primary purpose is not the production of energy, and which is therefore not necessarily recovered (the Renewable Energy Directive currently under revision will introduce a new definition of waste energy). The aim is to capture and then transport this heat, which would otherwise be lost, to promote its exploitation in thermal form. In the context of progressively limiting of the use of fossil resources and reduction of CO2 emissions, recovering and making the most of the energy wasted in certain processes is an essential objective for more rational energy use, in line with the objectives of the energy transition.
