The Environmental Protection Agency contracted with Corning Glass Works for the development of glass batch pretreatment process which would abate emissions and reduce energy usage in the melting furnace. The contract consists of two phases of work. Phase I, now completed and reported in this document, was a laboratory phase to supply the information needed to design a pilot plant system, and based on this design, to estimate the energy, pollution, and economic advantages of the program. Phase II will consist of constructing and operating a batch preheating pilot plant test facility to confirm the bench scale test results and to provide the necessary design and operating information for a full scale production facility. The Phase II results will also be used to update the energy, pollution, and economic advantages of the process.
