Its stake will go to the Universities Superannuation Scheme (USS).
The news follows an announcement earlier this week that Kanadevia Inova will take over as operator from DWTE.
Encyclis said that the move is the latest step in the strategic evolution of Encyclis’ EfW portfolio, which focuses on the development and operation of its core cluster of energy recovery facilities in the UK Midlands.
Encyclis CEO Mark Burrows-Smith said: “We are pleased to announce this strategic step as we continue to strengthen our core cluster of Energy from Waste facilities in the UK Midlands.
“The new ownership and operating structure at Dublin Waste to Energy will provide long-term support, while Encyclis focuses attention on the ongoing growth and optimisation of its central portfolio in the UK.”
USS added that the acquisition represents “a strong fit with its mandate” and that it is “committed to contributing to the plant’s continued success”.
The sale is expected to be completed in the summer of 2026, following mandatory approvals.
DWTE is a public–private partnership between the four Dublin local authorities and private investors, including Encyclis.
Located in Poolbeg, the EfW facility currently processes around 600,000 tonnes annually and provides heat that is fed back to the Dublin District Heating System.
Dublin Waste to Energy employs five people directly, with plant operations and maintenance managed separately.
A spokesperson for Encyclis said: “Employees, waste suppliers and partners have been assured of a smooth transition that prioritises safety and continuity.”
Future capacity upgrades
Following the handover, Kanadevia Inova will now oversee planned maintenance and upgrade works aimed at enabling the plant to reach its licensed capacity of up to 690,000 tonnes of residual waste per year – representing a 15% increase in processing capacity.
The upgrades will be made to boilers, combustion systems, cooling systems and ash handling systems.
Kieran Mullins, DWTE Project Director, said at the start of the week: “We have had an excellent relationship with Kanadevia Inova since our earliest days, and we are delighted that they will now operate and maintain our facility.
“DWTE continues as owner of the facility and remains accountable for the asset and its long-term strategy.
“Our joint focus will be on safe, compliant and reliable operations, while ensuring continuity for our employees, customers, suppliers and stakeholders.”
