The production of insulation fiberglass results in substantial quantities of waste products that must, in some states, be disposed of in hazardous waste landfills. the cost of landfilling these materials at a single plant often exceeds $1 million/yr. in the end, the cost of this practice is passed… More

The production of insulation fiberglass results in substantial quantities of waste products which must be disposed of in hazardous waste landfills in some states. the cost of landfilling these materials at a single plant is often in excess of $1 million/year which, in the end, is passed on to the… More

The disposal of all types of wastes, municipal, medical, andindustrial, is a significant and increasing problem facing the world environment today. most of the waste being generated is currently being landfilled; however, as many asone-third of the currently active landfills could reach capacity in… More

The incineration of sludge from municipal sewage treatment plant wastewater streams produces an ash that must be disposed of safely. ash from these facilities is produced at rates ranging from 10 to 100 tons per day, with disposal costs averaging $100 to $150 per ton. in some locations, the… More

It is clearly recognized by those associated with the coal industry that major deterrents to the use of coal are the gaseous, liquid, and solid waste products that are generated. in particular, the landfill requirements for solid waste products are becoming a major environmental and economic issue.… More

Fossil fuel fired vitrification technology is receiving increased emphasis as a potentially attractive means for oxidizing organic materials and immobilizing the heavy metal constituents in hazardous flyashes and dusts. since vitrification is a high temperature process, there is some volatilization… More

It is clearly recognized by those associated with environmental restoration that coal-fired boiler flyash is a significant contributor to the increasing shortage of landfill availability. in general, the landfill requirements for solid waste products are becoming a major environmental and economic… More

Vortec proposes to improve the IR transparency, thermal shock resistance, and processing of AlN through the exploitation of the unique properties of nanocrystalline materials. We will construct test windows consisting of nanocrystalline AlN where the grain sizes are on the order of about 100 nm. … More

Vortec proposes to eliminate much of the cost originating from the post ceramic processing machining of single mode ferrules through the use of nanocrystalline sintering aids. Single mode ceramic ferrules made from micro particle size powders u Using a yttria-stabilized zirconia body composition,… More
