4.3 Comparison of Technologies Chosen in Recent <br />Research/ Procurements <br />In the foregoing studies, reports and procurements, a total of 78 technology vendors <br />were represented, evaluated, screened or selected in some way for consideration as <br />waste processing solutions for the local entities. These 78 vendors offered 14 <br />different technologies. The listing of the 78 vendors is presented in Table A -1 in <br />Appendix A of this paper. Several of those technologies /vendors were mentioned <br />more than once. Table 4 -1 lists the 14 that were cited three or more times in the <br />various documents. <br />The most often cited technology was mass burn, represented by Covanta and <br />Wheelabrator, who have the most commercial experience of any of the vendors <br />listed. Second on the list is gasification firm IWT, which employs the Thermoselect <br />technology in use in Europe and Japan. Other gasification technology providers are <br />also mentioned, along with four anaerobic digestion vendors, one plasma arc firm <br />two pyrolysis providers and a thermal depolymerization firm. While this review is not <br />systematic, it does provide a good summary of the firms and technologies that are <br />most active in the field, and those that localities across the U.S have been most <br />interested in using as they contemplate alternatives to landfilling MSW. <br />Table 4 -1.
