The two companies are currently evaluating Covanta sites throughout the country to build additional CNG stations.Clean Energy reliably fuels thousands of natural gas solid waste trucks every day across the U.S. and Canada, and the numbers are growing rapidly. The new Clean Energy CNG stations at Covanta’s facilities will accelerate the transition of fleets from diesel to cleaner, more economical and more efficient natural gas fuel. Priced up to $1.50 per gallon less than diesel fuel (based on current market conditions), the use of natural gas fuel reduces costs significantly for vehicle and fleet owners, and lowers greenhouse gas emissions up to 23% in medium to heavy-duty vehicles. Additionally, natural gas is a secure North American energy source, with 98% of the natural gas consumed produced in the U.S. and Canada. Recovering energy from residual waste left over after efforts to reduce, reuse, and recycle is a critical component of sustainably managing waste. For every ton of municipal solid waste processed at Covanta’s Energy-from-Waste facilities, greenhouse gas emissions are reduced by the equivalent of approximately one ton less of carbon dioxide emissions. This is possible due to the avoidance of methane from landfills, the offset of greenhouse gases from fossil fuel electrical production and the recovery of metals for recycling. Covanta Energy Corporation (NYSE: CVA) is an internationally recognized owner and operator of large-scale Energy-from-Waste and renewable energy projects and a recipient of the Energy Innovator Award from the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy. Covanta’s 44 Energy-from-Waste facilities provide communities with an environmentally sound solution to their solid waste disposal needs by using that municipal solid waste to generate clean, renewable energy. Annually, Covanta’s modern Energy-from-Waste facilities safely and securely convert approximately 20 million tons of waste into 9 million megawatt hours of clean renewable electricity and approximately 9 billion pounds of steam that are sold to a variety of industries.
