When The Mosaic Co. wanted to study using phosphogypsum — a waste byproduct of the phosphate industry now heaped into small mountains — in road construction, it turned to the Sustainable Materials Management Research Laboratory at the University of Florida’s College of Engineering.
Environmental engineering professor Timothy Townsend works in Florida and around the world on sustainable solid and hazardous waste management. Mosaic, a Tampa-based Fortune 500 company that mines phosphate for fertilizer, has sponsored roughly $500,000 in research funding for his lab over the past three years for projects that seek to find beneficial uses for phosphogypsum.
