Retrospective plans to install an anaerobic digestion (AD) plant in the Forest of Dean, UK have been approved.
Plusterwine Biogas has been granted permission by district planners for three digesters with a feeder plant, two dryer units, and two 500 kW combined heat and power (CHP) engines at Plusterwine House, Woolast.
According to a report by Gloucestershire Live, the approved plans also include storage buildings, a boiler room, and a digestate lagoon.
The plant, already constructed, will be fed approximately 32,000 tonnes of maize, grass, and rye silage, crop residues, and farm manure annually. Plusterwine Biogas said some of the feed will be brought on-site from nearby farms during the harvest season, and some is brought to the site all year round.
Electricity will be produced and used for the farm and fed into the grid, while the excess heat from the process will be used to dry waste paper, maize and grass silage for animal bedding. The dried paper would be exported and the maize kept for bedding for cattle, before being fed into the AD plant.
The plant will produce 1 MW of renewable energy per year, which will be sold to the National Grid, combined with 2,000 kW of heat produced from the AD process.
On 13 July, local Councillor Brian Lewis said that despite some concerns from locals, there was a marginal preference for the plant proposals overall.
“We are very sympathetic with the problems of this proposal,” Lewis was reported as saying by Gloucestershire Live. “The thought of not going ahead with it might cause a lot of unnecessary problems.
“This is a financially viable proposal and I think we should support it.”
