Covanta Energy Corporation (formerly the Ogden Corporation) owns and operates worldwide over forty new generation waste combustion facilities with added benefit of energy recovery, also known as waste-to-energy or energy-from-waste power generation plants. Facilities operated by Covanta produce electricity for approximately one million homes in communities across North America by converting municipal solid waste into renewable energy. The company’s operations offset the production of approximately 20 million tons of carbon dioxide annually by producing electricity without utilizing fossil-fuel and by diverting waste from landfills. The energy-from-waste process also includes the extraction of ferrous (steel) and non-ferrous (aluminum etc.) metals either before or after the combustion process. Approximately 400,000 tons of ferrous steel and non-ferrous metals are extracted at the company's facilities annually for recycling, avoiding mining activities associated with the production of a similar amount of virgin metals. - Source: Wikipedia
