Plans have been announced to develop two plants in Moray producing biogas using distillery by-products, as well as crops and waste from local farms.
Acorn Bioenergy intends to invest around £50m developing a plant near Longmorn, on the outskirts of Elgin, and another at Hill of Rathven, by Buckie.
The company said the plants could help decarbonise the area’s whisky industry and provide a new source of income for farmers, as well as heating homes and powering heavy goods vehicles.
