Replacements for the halocarbons banned by the Montreal Protocol will be produced by technologies which generate spent catalysts as a waste byproduct. These spent catalysts contain tin, a valuable metal resource, in a matrix that will undoubtedly be classified as hazardous with regard to its disposal.

Chemical and Metal Industries, Inc., proposed in this Phase I effort to investigate two alternative technologies for recovery of tin values from this spent catalyst. The tin recovery processes also aim at minimizing or totally eliminating hazardous wastes associated with this spent catalyst. Recovered tin products from these processes can be directly recycled to the fluoroproducts industry or to other existing tin chemical markets. Organic wastes from the process can be disposed of as non hazardous solid wastes.

The successes of Chemical and Metal Industries, Inc., in recovering antimony values from similar classes of spent catalyst and their close association with the plants that will generate this new class of spent tin catalyst assures an excellent commercialization potential for successful processes developed in Phase I and Phase II research.
