SUEZ Wins €465 Million Contract to Rebuild and Operate Romainville–Bobigny Waste Treatment Centre

(IN BRIEF) SUEZ, alongside Chantiers Modernes Construction, has secured a 10-year, €465 million contract from Syctom to reconstruct and operate the Romainville–Bobigny household waste treatment centre in Seine-Saint-Denis. The project includes €237 million in investment to modernise the facility, expand its capacity to 450,000 tonnes per year and integrate biowaste processing. A strong focus is placed on river transport via the Ourcq Canal to reduce road traffic and emissions, as well as on environmental performance, urban integration and social inclusion. Delivered through an innovative semi-public company structure, the project will preserve continuous operations during construction and support long-term employment and circular economy objectives in the Île-de-France region.

(PRESS RELEASE) PARIS, 14-Jan-2026 — /EuropaWire/ — SUEZ, together with Chantiers Modernes Construction, a subsidiary of VINCI Construction, has been awarded a major contract by Syctom to reconstruct and operate the Romainville–Bobigny household waste treatment centre in Seine-Saint-Denis. The 10-year agreement, valued at €465 million, includes €237 million in investment aimed at modernising the facility and expanding its capacity to meet the evolving waste management needs of the Île-de-France region, which serves nearly six million inhabitants.

A central feature of the project is the comprehensive redesign of one of Syctom’s most important waste treatment sites, located at the intersection of the municipalities of Romainville and Bobigny. The centre currently handles 370,000 tonnes of residual household waste and 57,000 tonnes of packaging annually. Following reconstruction, the site will be able to process up to 450,000 tonnes of waste per year by 2029, including 350,000 tonnes of residual household waste, 40,000 tonnes of biowaste and 60,000 tonnes of packaging. The modernisation will also enable the facility to receive household biowaste from across the territory.

River transport is a key pillar of the project, supporting Syctom’s ambition to reduce road traffic and associated CO₂ emissions. The development includes the construction of a dedicated river port terminal on the Ourcq Canal, allowing between 165,000 and 183,000 tonnes of waste to be transported annually by waterway. Two to three barges per day will replace dozens of truck journeys, significantly reducing congestion, noise and emissions, while also facilitating the transport of recovered materials from packaging sorting.

The project is being delivered through an innovative governance model based on a single-operation semi-public company established from the construction phase onward. This structure, which aligns partner interests across the entire lifecycle of the project, is owned 60% by the SUEZ–Chantiers Modernes Construction consortium, with SUEZ holding 57% and Chantiers Modernes Construction 3%, while Syctom retains a 40% stake. The facility will remain operational throughout the 39-month construction period, which is scheduled to begin in March 2026, ensuring continuity of the public waste management service.

The reconstruction will fully modernise the site while preserving Romainville’s iconic sorting hall, recognised by its cable-stayed roof. This architectural landmark will be integrated into a contemporary complex designed to meet future regulatory requirements and the area’s long-term waste management needs. The new centre will be organised around four complementary hubs and five facilities, including a new household waste reception and transfer area, a biowaste transfer centre, continued packaging sorting operations, a river port platform connected to the Ourcq Canal, and a dedicated Centre of Excellence for the Circular and Solidarity Economy. The latter, operated by the Est-Ensemble Territorial Public Establishment, will include a household waste drop-off point, a reuse centre and community spaces separate from the industrial facilities.

Environmental performance and urban integration are core elements of the project. From the construction phase onward, stringent measures will be implemented to limit noise and dust, remediate soils and preserve biodiversity. The centre will feature fully enclosed facilities equipped with advanced air treatment systems to ensure effective odour control. Extensive reuse of materials and contemporary architectural design will contribute to improving the image of waste treatment professions, while educational and public-facing spaces, including observation points and awareness rooms dedicated to waste reduction, will open the site to the wider community.

The project also places strong emphasis on employment and social inclusion. The operating company will employ 138 permanent staff, with all existing employees retained. Additional recruitment will be carried out in partnership with local employment agencies to support access to jobs within the surrounding communities. Through its subsidiary Rebond, SUEZ will also deploy an inclusion programme representing 320,000 working hours, supporting sorting operatives on integration pathways with tailored supervision and professional development.
