The disposal of all types of wastes, municipal, medical, and industrial, is a significant and increasing problem facing the world environment today. Most of the waste being gener- ated is currently being landfilled, however, as many as one- third of the currently active landfills could reach capacity in the next four years. As the capacity of the landfills decreases and the landfilling costs increase, incineration becomes an attractive means of volume reduction. However, one byproduct of the incineration process, flyash, contains a high concentration of heavy metals which have to be disposed of in hazardous waste landfills at a significant increase in cost to the incinerator operators and, ultimately, the public. Municipal Solid Waste (MSW) incinerators alone produce approximately 450,000 to 800,000 tons of flyash annually. Disposal of this flyash in hazardous waste landfills could cost from $100 millon to $800 million annually, depending on the location of the landfills.

The development of an advanced flyash/dust vitrification system is proposed as a means of eliminating the flyash disposal problem associated with incineration. The technol- ogy being proposed is based on advanced in-flight suspension glass melting technology being developed by Vortec Cor- poration for the U.S. Department of Energy.

Phase I of the development program will verify the technical and economic feasibility of flyash vitrification in an ad- vanced cyclone melting system via testing with a pilot-scale facility. The system will vitrify the material in such a manner as to produce a product which will meet the criteria for disposal in a non-hazardous landfill and may have a commercial value.
