Spanish construction firm Acciona and HZI had a joint bid to construct the plant approved by the North London Waste Authority (NLWA) in December 2021, and a target has been set to have the plant operational for 2025.
In a statement yesterday, HZI said it will begin work to deliver the “newest and most advanced technology for the plant”.
This includes providing ‘chute to stack’ technology for the EfW, using “proven technology” to treat up to 700,000 tonnes of non-recyclable residual waste each year.
Technology
The Edmonton EfW will utilise moving grate technology with an associated heat recovery boiler, flue gas treatment plant and stack.
A carbon filter odour control unit will extract air from building.
The new plant will also feature selective catalytic reduction technology, which converts the nitrogen oxide created by incinerating waste into water and nitrogen, “a harmless gas that makes up 78 per cent of the Earth’s atmosphere”.
This is also used at the Amager Bakke/Copenhill ERF in Copenhagen, recently featured in the BBC’s Earthshot Prize and which even has a dry ski slope on the exterior “because the pollution controls are so effective”.
‘Proud’
Fabio Dinale, HZI’s vice president business development, said: “HZI is proud to be part of the new facility to replace the current plant at Edmonton in north London.
“The new ERF will further contribute to the NLWA’s drive to treat residual waste more sustainably and will support the UK’s aversion from landfills as well as the countries decarbonisation strategy. Once operational in 2026, the new facility will allow significant amounts of energy and valuable materials to be recovered and lower north London’s overall carbon footprint”
Decarbonisation
The current Edmonton EfW is decades old and due to be demolished.
According to the NWLA, the new facility aims to prevent residual waste from ending up in the landfill, where it generates methane, a greenhouse gas which has a warming impact 80 times greater than CO₂.
The new ERF will aim to save the equivalent of 215,000 tonnes of CO₂ each year – the equivalent of taking 110,000 cars off the roads.
The NLWA project will be the 15th EfW plant HZI has worked on across the UK.
