AmeyCespa has been chosen as the preferred bidder to design, build and operate an “innovative” new waste treatment plant in Milton Keynes.
The plant, to be built in the Old Wolverton industrial area, will combine three technologies to treat black bag waste and some commercial waste: mechanical treatment; anaerobic digestion; and a thermal treatment facility to turn remaining waste into gas for electricity.
The outputs of the system are expected to include recyclate, digestate, and enough renewable energy to power 11,000 homes.
The plant was hailed as ‘innovative’ by Cllr David Hopkins, who said: “Milton Keynes Council has an excellent recycling record and has set out to build on this by recovering as much as possible for recycling and composting from our black sack waste and generating renewable energy with what’s left.
“Following dialogue with AmeyCespa, we believe they have come up with an innovative long-term, value for money solution which will meet these aims.”
An AmeyCespa spokesman told MRW: “The innovation comes from using mechanical, biological - anaerobic digestion and composting - and advanced thermal treatment on the same site. By mixing these treatment technologies we will be able to maximise the selection of materials – achieving up to 30% materials recovery.
“The technology will also maximise environmental benefits including cutting landfill by 95% (overall diversion figure for the whole site).”
AmeyCespa said they have taken a similar approach at Allerton Waste Recovery park in North Yorksire: “We are co-locating mechanical and biological treatment (MBT) with thermal treatment for the refuse of the MBT.
“As far as we are aware no other company is taking this approach on current projects in the UK, although these technologies are being used separately in other projects in the UK.”
Amey Cespa said they will be submitting the planning application for the Milton Keynes Waste Recovery Park in 2013, following a consultation period.
This announcement makes the Milton Keynes facility the third AmeyCespa site across the UK at either the planning or operation stages.
