BOARDMAN, Ore. – It may not smell that way, but old tires and cow manure could mean clean energy at Threemile Canyon Farms near this town.
Portland-based Northwest Biogas has proposed using the tires and cow manure to make methane on the 93,000-acre dairy farm and wants a permit from the Oregon Department of Environmental Quality to store waste tires.
Northwest Biogas wants to use 40,000 waste tires to help grow micro-organisms in an anaerobic digester. Using the tires eliminates the potential for tire fires or the breeding of vectors, such as mosquitoes.
