AAMC Reporter, October 2007 Jack Tarpley, UTMB's institutional safety officer, is quoted in this article about how medical institutions are recycling more and improving energy efficiency. Tarpley told the magazine that histopathology labs at UTMB are able to reuse certain solvents, thanks to state-of-the-art distillation units that annually conserve five to seven tons of chemicals and save up to $19,000.
