As a global leader in the water and waste management sectors, we have been operating for over 160 years all over the world. We provide essential services to protect the resource and improve quality of life wherever we operate.
Our solutions
Electricity, heat or steam production
We transform residual waste into electricity and heat to help meet the energy needs of local industrial and household consumers.
This energy production puts you at the centre of the energy transition process, providing multiple benefits such as:
- energy self-sufficiency for a treatment plant,
- reduced energy bills for local buildings (hospitals, administration buildings, etc.),
- deliver heat to urban heating networks,
- boost the portion of renewable energy in your local energy mix, whether through public or private heating networks.
We implement a diverse range of processes to transform all types of residual waste into energy:
- Waste to energy:
- The heat produced by the combustion of non-hazardous waste heats up a water circuit which in turn, drives turbines and generates electricity and/or heat,
- Treatment and incineration of hazardous waste in special flues at the heart of chemical plants to supply energy as steam to industrial customers.
- Production of substitute fuels: waste is treated to obtain substitute liquid and/or solid fuels with a high calorific value (CLS, CSS).
- Cogeneration enables the production of both types of energy simultaneously. The CHP+® process developed by SUEZ enables the recovery of residual heat generated by waste combustion and its use in local activities.
Biogas production
When buried, the fermentation of certain waste generates biogas. This can be used as a valuable contribution to local energy mixes.
We propose biogas recovery methods specifically suited to local contexts: natural gas transport or distribution networks nearby, local energy needs (residential, public buildings, tertiary, industrial), presence of LNG refuelling stations, etc.
We deliver end-to-end support on your project: design and engineering, selection and dimensioning of channels, construction of biogas units, operation and through-life optimisation of facilities.
We also propose an anaerobic digestion service, mixing together organic household waste with waste from business activities and agriculture. Methane offers a calorific value 25 higher than CO2. Once captured and recovered, the methane is injected into urban and industrial supply networks to replace natural gas.
