During this Phase I research project, MO-SCI Corporation will develop a method for recycling industrial phosphate waste as a low-cost raw material for innovative iron phosphate glass fibers. Iron and zinc phosphate sludge generated by the automobile, heavy equipment, appliance, fastener, and other industries using metal phosphating processes typically is landfilled. Preliminary work on industrial phosphate waste has shown that the waste composition is close to ideal for use as a raw material in the manufacture of innovative iron phosphate glass fibers. Iron phosphate glass fibers hold promise as a low-energy, environmentally friendly alternative to conventional silica-based glass fibers with commercial application as reinforcing fibers, insulation, and filters.
