MAN ES and Bonatti collaborate on EDF PEI bioenergy plant
A consortium comprising MAN Energy Solutions and EPC (engineering procurement and construction) specialist, Bonatti, has signed a contract with EDF PEI (a 100% owned subsidiary of EDF that builds and operates power generation facilities in the French overseas departments and regions, and Corsica) for the construction and maintenance of a new power plant at Ricanto, near Ajaccio, Corsica. It will replace the aging Le Vazzio plant, with commercial operation expected in late 2027/early 2028.
The plant, with a total installed capacity of 130 MW, will be equipped with 8 × MAN 18V51/60 engines optimised to run on 100% liquid biomass fuel of plant origin.
Speaking at the contract-signing ceremony, Uwe Lauber, CEO of MAN Energy Solutions said: “The Ricanto power plant will play an essential role in guaranteeing Corsica’s energy security
while significantly minimising its ecological impact. MAN 18V51/60 engines are specially designed to accommodate running on liquid biomass with optimum performance and efficiency.”
MAN PrimeServ – the after-sales service of MAN Energy Solutions, which already provides maintenance for several existing EDF PEI power plants – will take on maintenance of the Ricanto bioenergy plant.

Under a 25 year long-term service agreement MAN PrimeServ will be responsible for spare parts, major maintenance porojects, technical services and training modules for EDF PEI personnel.
Stricter standards for UK EfW new builds
New waste incinerators, including energy from waste facilities, will only receive planning approval if they meet strict new local and environmental conditions, the UK government announced on 30 December. They will also need to ensure that new projects are built carbon capture ready and also show how they will make use of the heat they produce.
New evidence – published in the Residual Waste Infrastructure Capacity Note – shows that tougher new requirements for proposed waste incinerators will not negatively affect the country’s capacity to process waste and should decrease the amount sent to landfill. Over the last 14 years, England has seen recycling rates stall, meaning too much waste is dealt with through incineration
or thrown in landfill. Almost half of all waste (49%) collected by local authorities in 2022/23 was incinerated, with just 40% recycled. “Increasing recycling rates, and developing carbon capture as well as district heat networks across the UK’s EfW fleet, will all play a role supporting our sector’s target to decarbonise by 2040,” said Charlotte Rule, Head of Climate and Energy Policy at the Environmental Services Association (ESA).
Current projections suggest that by 2035, UK energy from waste plants will be capable of dealing with 18.8 million tonnes of residual waste. However, with the delivery of the government’s collection and packaging reforms, and “the transition to a circular economy”, the country
will only need to manage 17.6 million tonnes of non-recyclable waste by 2042, the government estimates. “This means there is a limited need for the development of further waste incinerator plants.”
Nevertheless, “while there is a need to minimise waste incineration, it remains a better option than throwing rubbish into landfill” and incineration facilities are estimated provide around 3% of the UK’s total power generation. The government says it will explore how it can ensure that new waste incineration plants, albeit limited in number, are capable of exporting heat from day one and are incentivised to export heat as soon as possible after commencing operation.
Viridor selects Kanadevia Inova for Tilbury waste-to-energy plant
Kanadevia Inova (formerly Hitachi Zosen Inova) has signed an EPC contract with Viridor to build a new 40 MWe waste-to-energy (WtE) plant at Tilbury Docks in East London, the Thameside Energy Recovery Facility (TERF). The project is seen as a “major milestone” by Kanadevia Inova, with the Swiss company undertaking the role of principal contractor, designing, building and commissioning TERF. Once completed, the new plant will be Kanadevia Inova’s twenty-first WtE project in the UK.
After a 42-month build and commissioning period, the new facility is aiming to enter commercial operation in 2028.
The new combined-heat-and-power-enabled plant is described as a “highly efficient” single-line facility capable of treating up to 350 000 t of non-
recyclable waste per year. As the construction phase progresses, Viridor will consider the plant’s combined heat and power options together with future carbon capture and storage opportunities, in line with UK government policies (see previous item).
Meanwhile, construction has started on Kanadevia Inova’s 20th WtE project in the UK, the Encyclis Energy Recovery Facility in Walsall, which will “divert up to 436 000 tonnes of non- recyclable household and business waste away from UK landfill sites and overseas treatment,” the company says.
The Walsall single-line facility is aiming to achieve an annual guaranteed availability of 98%, making it “one of the most efficient plants ever to be built in the UK”, says Kanadevia Inova.

The non-recyclable waste will be used to generate up to 49 MW of electricity, and the facility has also been designed for the future export of steam, potentially supplying up to 20 MWt of heat for use in a district heating scheme.
