S4 Energy Solutions LLC, a joint venture by Waste Management, Inc. (NYSE: WM) and InEnTec LLC, announced plans to develop a plasma gasification facility at Waste Management’s Columbia Ridge Landfill in Arlington, Oregon. The planned facility will convert municipal solid waste into fuels and energy.
