The new plant will have two incineration lines, which will be equipped with HZI’s own EfW technology. Once completed, the plant will process up to 410,000 tonnes of residual waste and use it to generate 49MW (gross) of renewable base load electricity per annum. This is enough energy to power more than 100,000 U.K. homes. The scope of works for the Careys team includes:

  • Earthworks.
  • Drainage and underground systems.
  • Earthing.
  • Storm, fire and process water drainage.
  • Concrete structures including - Tipping Hall, Waste Bunker (slipform), Boiler House, PCC lift Core & tower crane foundations, FGT building, stack foundation, turbine hall, steam turbine & generator foundation and turbine table.
  • Various Storage Tanks, Fire Water Tank, Fire Water Pumphouse and storage areas.
  • External works including hard and soft landscaping.

Coordination around other key contractors on site will need to be carefully managed and mitigated with coordination meetings and programme management with the client. Working for Hitachi Zosen Inova (HZI), the project based southeast of Leeds in Stourton started in August 2022 and ran for 55 weeks. There were on average between 40 and 70 operatives on site, with this peaking to approximately 140 during the slipform operations. Full commissioning of the plant is planned for 2025.
