Vitro Minerals recently announced the completion and start-up of a 40 million lbs/year recycled glass powder plant in Jackson, Tenn. The glass powders are designed to provide a 100% recycled, crystalline-silica-free alternative to traditional mined mineral fillers and extenders, such as calcium carbonate, clay, silica, and nepheline syenite. 

Vitro Minerals has reportedly developed a variety of post-consumer and post-industrial glass sources and unique processing schemes to make glass powders with excellent particle size control and brightness standards equal to traditional mineral fillers. The resultant glass powders can act as cost-effective functional fillers in coatings, plastics, adhesives, sealants, and concrete.  The powders are available in different glass chemistries, in particle sizes from 0.5 microns to 500 microns.
