Abstract
A process for making commercial-quality glass wool from the glass fraction of minicipal incinerator residues was developed by the Bureau of Mines. This research was a part of the Bureau's program to recover usable materials from reclaimed urban waste. Molten glass was fiberized into glass wool on a laboratory scale by impinging a jet of compressed air on a stream of the molten glass. Melt compositions were varied by adding dolomite and alumina to obtain molten glass with the handling characteristics required for producing final wool products of the desired composition and physical characteristics. When no charge is made for the waste glass and a credit of $70 per ton is allowed for the wool product, a 10 percent rate of return on investment after taxes is possible. If a charge of $5 per ton is placed on the waste glass, a selling price of about $72 per ton would be necessary to obtain a 10 percent rate of return.
