Eiffage and NGE recently jointly signed the contract with SUEZ for the civil engineering of two waste-to-energy plants serving Toulouse and northern Haute-Garonne department. This contract is part of the concession for managing these units awarded to SUEZ and Banque des Territoires by the Decoset Joint Association. The deal is worth a total €132 million (Eiffage 60% and NGE 40%)

The deal agreed with the consortium, led by Eiffage through its subsidiary Eiffage Génie Civil, includes two contracts:

- The design-build modernisation of the Bessières waste-to-energy plant, with the works expected to take 16 months, including eight months of studies, for handover in June 2026.
- Civil engineering works for the new waste-to-energy plant in Toulouse, with capacity of 240,000 tonnes a year, based on plans created by the two firms of architects Richez Associés and Séquences. This 56-month construction project will be delivered in mid-2031.

Once commissioned, the two waste-to-energy plants will provide a major boost to energy production, generating more than 220 GWh of electricity per year and more than 360 GWh of heat per year from the residual household waste of over a million people in the region.

The ambition of this project is to respond to the challenges of energy and circular economy in order to support the territory’s sustainability transition.

“Following the completion of civil engineering works of l’Interval, for the future Ivry‑sur‑Seine waste-to-energy plant, due to enter service in 2025, this new contract is an opportunity for Eiffage Génie Civil to consolidate its expertise in waste treatment facilities. This new contract also highlights our proficiency in managing large-scale forward-looking regional projects.”

Guillaume Sauvé, Chairman, Eiffage Génie Civil and Eiffage Métal

“Following on from the Wattrelos purification plant in the Hauts‑de‑France region, this waste-to-energy project for Toulouse and northern Haute‑Garonne department epitomises NGE’s expertise in industrial civil engineering and our ability to implement real-world solutions for the energy transition. By helping to create this infrastructure, we are playing an active role in transforming the region – toward a responsible, sustainable energy model.” Jean Bernadet, Chairman of NGE
