A new process developed by Ohio State University and federal EPA researchers that uses tiny phosphate rocks to neutralize lead in soil, sand, sediments, sludges, and solid and hazardous wastes has been licensed to a Texas firm. In the new process, the phosphate joins with lead and renders it insoluble within 24 to 48 hours after application. Treating an acre of soil with phosphate rocks costs hundreds of dollars, versus thousands or tens of thousands with other technologies. The licensee, Proactive Environmental Research Laboratory of Houston, will use the process to recycle glass from computer and television monitors. Robin Rasor, associate director of Ohio State's Office of Technology Transfer, called the licensing agreement a win-win relationship with Ohio State's research partner on the project, the Office of Research and Development's National Risk management Research Laboratory of the Environmental Protection Agency in Cincinnati.
