Marl Creek Renewables
Carl Frook operates a cattle feeding operation which consists of 1,800 head. The farm is also associated with Marl Creek Renewables, which includes a 4,200m3 anaerobic digester designed by BioEN Power. Manure, milk, fats, oils and grease are fed into the anaerobic digester, which supplies fuel for the operation’s two 250kW combined heat and power units. Electricity is sold to the electrical grid and heat recovered to assist in the anaerobic digestion process. The digestate produced is used as fertilizer for associated farmland.
