The plan is central to a £900m contract that the West London Waste Authority has signed with a consortium led by Sita UK.
Sita UK will collect waste from the boroughs of Brent, Ealing, Harrow, Hillingdon, Hounslow and Richmond-upon-Thames and send it more than 100 miles to a new waste-to-energy plant in in Severnside, South Gloucestershire.
Sita is part of a consortium with Lloyds Banking Group and Itochu Corporation that has been named preferred bidder for the 25-year public private partnership deal.
The Severnside Energy Recovery Centre (SERC) already has planning permission and will cost £240m to build. Around 200 jobs will be created during its construction. It is expected to produce enough electricity to power 50,000 homes.
It will be built on a site adjacent to Seabank Power Station and the former Terra Nitrogen plant.
