SUEZ expands UK operations with £396 million Milton Keynes City Council contract win, and two new facilities under construction, to support the development of the circular economy

• The Group secures new 10-year contract with existing customer Milton Keynes City Council to operate and maintain their waste recovery park, and an interim contract to operate the NESS energy from waste facility in Aberdeen.
• Two new plants begin construction showcasing SUEZ’s cross-sector expertise with a new anaerobic digestion plant in Northumberland to produce biogas from food waste, and the expansion of a lithium battery recycling facility, increasing SUEZ’s capabilities in this growing market.
• These commercial developments demonstrate SUEZ’s trusted expertise and leadership in circular solutions for waste and resource management in the UK.
  

Xavier Girre, CEO of SUEZ, said: “The United Kingdom is an historical and major market for SUEZ, accounting for a third of our global waste management activities. We are determined to remain a leading player in the country by leveraging our expertise, innovation and investment capacities. These new contracts with long-term clients and the development of critical facilities illustrate our commitment to serve our clients at all stages of the waste value chain: from collection, sorting, recycling, to thermal treatment, anaerobic digestion and gasification of biowaste.”

Trusted expertise in operating critical infrastructure in the UK

In recent months SUEZ has signed two major new contracts with long-term customers to operate their critical assets.
Milton Keynes City Council has awarded SUEZ a new 10-year, £396 million contract, to operate and manage the Milton Keynes Waste Recovery Park (MKWRP) from October 2026. The facility treats up to 133,000 tonnes of non-recyclable waste each year from Milton Keynes and West Northamptonshire and creates power equivalent to that used by 10% of Milton Keynes’ homes.
Since September 2023, SUEZ has delivered household collections and street cleansing for Milton Keynes City Council. This collaboration has improved the collections service, with more than 98,000 tonnes of waste collected each year, and has significantly increased recycling in the city, which has become England’s leading city for recycling.
In a further show of the trust and willingness to partner with SUEZ in the UK, the Councils of Aberdeen, Aberdeenshire and Moray also awarded SUEZ an interim contract to operate the NESS energy-from-waste facility in Aberdeen from December 2025.
The NESS facility can process up to 150,000 tonnes of non-recyclable waste each year – feeding a Combined Heat and Power facility with the ability to provide up to 10 MWth of heat to support Aberdeen City Council’s district heat network.

Enhancing and expanding SUEZ’s capabilities in the UK 

With mandatory weekly food waste collections for councils in England in force since April 2026—SUEZ is starting construction on a new anaerobic digestion plant near Ellington in Northumberland. Once operational towards the end of 2027, the plant will be able to process up to 50,000 tonnes of food waste annually, producing a recycled fertiliser product and enough green gas for around 5,500 homes.
Construction is also underway on a new battery recycling plant for large-format lithium batteries, such as those used in electric cars and e-scooters. This project relocates the existing facility in Luton, operated by SUEZ since December 2023, to larger premises in Northamptonshire, increasing capacity to 22,000 tonnes per year. It adds an extra processing stage to separate the lithium flake into individual components and produce black mass. With the rapid growth in lithium battery use across multiple sectors, the new plant will provide vital infrastructure to ensure the sustainable processing and recycling of batteries as they reach end of life.
