® Integrated Waste Services Association: <br />®• The trade organization for owners and operators of WTE facilities in the United <br />States <br />® Represents approximately $0 percent of the existing modern WTE facilities in the <br />United States <br />® Duke Energy Corporation: <br />® Has a Renewable Energy and Carbon Strategy Office that promotes WTE <br />® Blue Ridge Environmental Defense League: <br />® A regional community-based nonprofit environmental organization <br />® Founding principles include earth stewardship, environmental democracy, social <br />justice, and community empowerment <br />In addition, County staff hosted meetings and discussions with UNC representatives and their <br />consultants regarding their long-term energy management activities, and SWAB hosted meetings <br />and discussions that included some of the above listed organizations, as well as Orange County <br />Voice, regarding this and other solid waste issues. <br />® ~ ' ~ <br />Each of the technologies investigated has "pros and cons" regarding its performance, costs, and <br />risks. Of those investigated, the following are considered to have the best possibilities as long- <br />term disposal alternatives for Orange County. <br />2.1 Mass-Burn <br />® One of the two predominant technologies for WTE facilities in the world. <br />® Includes integrated furnace/boiler design (waterwall boiler) and modular design (with a <br />hearth-type furnace and a waste heat boiler). <br />® The integrated design (used in newer facilities such as Montgomery County, Maryland and <br />Fairfax, Virginia) tend to be able to meet higher environmental standards than the modular <br />units (used in some older facilities such as Pittsfield and Agawam, Massachusetts). <br />® Considered the most "proven" because it has the most varied and demonstrated perfor- <br />mance track record. <br />® Has one of the lowest risks of technical failure among the WPT technologies. <br />® Charges un-processed MSW into a boiler or furnace to be combusted and captures heat <br />~. <br />from the thermal conversion of waste to generate steam. j <br />rp <br />17 ~ <br />"°r,b Ne~u~~s 2 Apri116, 2009 <br />
