Lethbridge Biogas uses an anaerobic digestion process operating at 38 degrees C for the production of renewable energy. Anaerobic means 'in the absence of oxygen. The Lethbridge biogas/cogeneration plant processes organic residues such as agricultural manures and food processing by-products. It uses the biogas generated in 2 * 1.425 MW combined heat and power units (CHP) to produce green and renewable electricity for the Alberta grid. Heat captured from the CHP's is used to keep the process at its operating temperature at all times. Situated in the County of Lethbridge 'Rave Industrial Park', Lethbridge Biogas has access to an abundance of organic "fuel" within a radius of 2-30 km.
