The decision comes after Viridor listened to residents concerns about the plant during public consultations and following the Scottish Governments guidance on waste management, which sets out a clear and important role for EfW.
Viridor no longer plans to take municipal waste from the two furthest authorities West Lothian and the Scottish Borders. The amount of residual municipal solid waste to be processed at the facility will be reduced to 150,000 tonnes alongside 150,000 tonnes of residual commercial and industrial waste.
In total, 300,000 tonnes of waste will generate over 25MW of electricity with the potential to also provide heat to a number of local businesses.
Viridor external affairs manager Dan Cooke said: The reduction in size and capacity allows the facility to reflect local need and the aspirations of the Scottish Government. The revised proposals also address local views from the public who were keen to see a smaller EfW facility that is less reliant on road transport and come following wide consultation.
The Scottish Government has set challenging targets for recycling waste which aim to ensure 70% of waste is recycled, with only 5% going to landfill and 25% to EfW facilities by 2025.
Cooke added: Viridor is committed to working to improve recycling levels and uses a whole range of technologies across the country to recover valuable raw materials from our waste. Even the bottom ash from EfW facilities can be reused as an aggregate in road building.
Viridor will work with local authorities supplying waste to the facility in managing and improving their recycling and collection programmes by reviewing inputs into the plant and feeding back on the best way to ensure all possible recyclates are removed.
