Work progresses on Isle of Wight EfW facility

Building works have been “substantially completed” at Amey’s waste treatment facility at Newport – being delivered on behalf of the Isle of Wight council – with the facility expected to be fully operational by summer 2019.  

The complete development is being undertaken by three principal contractors: Trant Engineering Limited for the civil engineering, Stadler Engineering for the Mechanical Treatment (MT) facility and Michaelis Environmental Technology for the energy from waste (EfW) facility.

According to Isle of Wight council, building works at the site have been “substantially completed”

Construction works began in April 2017, starting with the demolition of the old treatment facility.


Currently the work programme of Stadler Engineering is at “the most advanced stage,” the council says, with the building works being substantially completed and the MT plant programmed to commence cold commissioning in the Autumn.

“The steel frame for the Michaelis plant has also been substantially completed and the boiler, furnace and steam generator delivered to site for installation,” the authority explained.

Staff have been recruited to run the MT plant which is due to commence commissioning and testing in September 2018.

It is planned that the mechanical treatment plant will be operational from winter 2018 and the EfW facility by summer 2019.


“I’m really pleased that work is continuing at pace on the new council site at Forest Park, Newport,” said Cabinet member for waste management, Councillor Michael Murwill.

“The new development will improve our recycling figures further, although recycling rates have increased already since the new contract with Amey commenced, due to the efforts of the public embracing the enhanced front end waste segregation.

“It will, when fully operational, play an important part in achieving the council’s aim to divert 90 percent of waste away from landfill and recycle 55 percent of household waste by 2020.”

The site will take kerbside household waste when fully operational and will also be available for commercial waste carriers.


The facility at Forest Road, Newport, is being delivered by contactor Amey for the Isle of Wight council, under a waste collection and treatment contract which will span 25 years. The facility will be owned by the council and will be operated by Amey.

The mechanical treatment plant will see all contracted dry recycling sorted and graded, the council said. It will also sort black bag waste, removing the lower quality recyclables, also for market, before converting up to 44,000 tonnes of non-recyclable waste to fuel via the EfW plant.

The EfW plant is set to produce up to 23,000 megawatt hours of energy per year, once up and running.

‘State of the art’ technology will be used to sort clean recyclables, to sell to the reprocessing market and will sort dirty recyclables (lower quality) from the black bags to sell onto available re-processors. Paper and card will be transferred to paper mills from this site and food will be transferred for anaerobic digestion.


The site at Forest Park was awarded planning permission in March 2016, and permitted to treat up to 44,000 tonnes of refuse derived fuel per annum.

Last year, the Environment Agency granted a variation of permit for the facility, to change from gasification to direct burn incineration (see letsrecycle.com story).

The switch to a direct burn incineration – or ‘moving bed technology’ – followed years of difficulties on the island with its early gasification system that saw various modifications implemented, and which were not always successful.

The choice of a moving bed system followed a planning application in 2016 by Amey to renovate and rebuild the existing ‘gasification’ plant at Forest Park, which was originally scheduled to be completed by summer 2018.
