What we are objecting to...
Acorn Bioenergy Ltd have applied for planning permission to construct and operate an anaerobic digestion plant on land currently occupied by Spring Grove Farm, owned by the Thurlow Estate and situated next to the A1307 just outside both Haverhill and Withersfield.
The 11-hectare plant would be used to convert farming waste such as rye, oat, maize and grass sileage, straw and poultry litter into gas for heating and transport.
Whilst anaerobic digestion can be a good way to use waste to create biofuel, it needs to be done efficiently and responsibly.
That means siting and operating plants on land that can’t be used for much else and avoiding negative impact on the local environment and the local population.
This is not what would happen here - we believe the site is too close to existing residential areas, would significantly impact travel & traffic, and could negatively affect the local environment.
