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

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