The report presents the results of a preliminary marketing study within an economic distance of the metropolitan New York area (North Hempstead) for the products from a potential plant for incinerator residue separation. A preliminary design and the operating and capital costs for such a plant are also given. Incinerator residue processed through a pilot separation plant was analyzed and used for product samples. Marketing investigations of the ferrous, nonferrous, glass, and sandash fractions were done with purchase letters of intent being sought. Income from the sale of the products to potential customers was determined as well as any associated transportation costs. The design criteria for the potential 150 TPD plant for North Hempstead are given, and a potential facility, based on the Bureau of Mines process with some modifications, is described in detail. Capital and operating costs for this facility for two- and three-shift operations are tabulated. The savings and other possible benefits from such a resource recovery facility are discussed. The appendix contains a compilation of the marketing contacts and significant replies. Portions of this document are not fully legible.
