34 <br />3.0 Worldwide Experience of Waste Processing <br />Technologies and Vendors <br />A variety of WPT are discussed in Appendix B and a summary matrix is in Appendix <br />A, Table A -2. This section discusses the past and current experience of WPT in the <br />U.S. and elsewhere. <br />3.1 Mass - Burn /Waterwall Combustion <br />No new mass -burn WTE facilities have been built in the United States for the past ten <br />years, although there have been acquisitions and ownership and operator changes at <br />certain existing facilities, as well as some plant expansions. As a result, the firms <br />associated with mass -burn WTE are operators, owners, or owner /operators of <br />existing facilities. As shown in the Table 3 -1, Covanta and Wheelabrator own and <br />operate the majority of privately -owned WTE facilities. Most of the WTE plants, both <br />public and private, are operated by Covanta, Montenay /Veolia or Wheelabrator. <br />Table 3 -1 also shows the range in tons processed per day between facility owners <br />and operators, with publicly operated facilities processing smaller amounts of waste <br />than those operated privately. <br />Table 3 -1.

The two leading suppliers of WTE <br />grate systems in the United States and overseas are The Martin Company of <br />Germany and Von Roll of Switzerland. <br />While new WTE facility procurements have declined in the United States, the market <br />for this equipment has increased in Europe and in Eastern Asia, with European and <br />Japanese systems suppliers actively marketing their systems, and consistently <br />improving their performance. This technology is well tested and is used more than <br />any other for large WTE facilities in the United States and overseas. <br />3.2 Mass - Burn /Modular Combustion <br />Modular systems are used for smaller WTE facilities (between 80 - 360 TPD) and for <br />industrial applications. Unlike mass burn /waterwall systems, there are a number of <br />American firms supplying such systems in the United States, and they are very <br />competitive in overseas markets as well. The more active of these suppliers are <br />Consutech Systems of Richmond, Virginia, Enercon Systems, Inc. of Elyria, Ohio, and <br />3 Integrated Waste Management Services Association, 2004 Directory of WTE Plants. <br />GBB/C08027 -01 5 August 15, 2008 <br />
