Queensland Department of Environment and Resource Management
"People's quality of life depends largely on the quality of the environment . . . The Department of Evnironment and Natural Resource Management (DERM) plays a vital role in protecting this environment. . . One piece of legislation administered by DERM is the Environmental Protection Act 1994 (EP Act) which regulates activities and substances which have the potential to harm the environment. The EP Act has identified Perchloroethylene (Perc) as being one substance that has the potential to adversely impact on the environment."
"What alternatives are there to using Perc? Several alternatives exist using silicon- water- and carbon dioxide-based solvents. These alternatives can be more energy efficient, and can avoid the cost of hazardous chemical disposal and health and safety concerns associated with Perc." Omar Ameer, A/Director Compiance and Investigations, 3 October 2009.
