Perma-Fix Becomes First Company to Treat Radioactively Contaminated Liquid Elemental Mercury Waste

OAK RIDGE, Tenn., April 10 /PRNewswire-FirstCall/ -- Perma-Fix Environmental Services, Inc. (Nasdaq: PESI; BSE) (Germany: PES.BE) today announced that it has completed successful treatment of radioactively contaminated liquid elemental mercury waste, which has been accomplished through proprietary technologies, developed in cooperation with ADA Technologies, Inc. Much of this waste has been in storage since the early Cold War, awaiting a treatment methodology that would render the waste acceptable for disposal.

Since the early 1950s, mercury has been widely used throughout the Department of Energy (DOE) complex for activities associated with the production of weapons and various research and development projects. The legacy is more than 50,000 cubic meters of low-level radioactive and transuranic wastes co-contaminated with mercury. Radioactively contaminated mercury wastes require complex treatment processes that meet the requirements of federal regulations and disposal site criteria. Perma-Fix and ADA have partnered to address the different types of legacy mercury wastes so that the government and commercial sectors will have a safe and proven means to dispose of these wastes. The availability of this elemental treatment system offers the government and commercial sectors a breakthrough treatment option for this problematic waste stream.

Dr. Louis F. Centofanti, Perma-Fix chairman and chief executive officer, commented, "We are excited to begin this treatment process that will support the DOE's effort to clean up legacy waste generated at sites throughout the United States. This new treatment technology expands our capabilities and is another example of how Perma-Fix is working diligently to commercialize technologies to address such problematic waste streams, existing at government and industrial facilities."

Cliff Brown, President of ADA Technologies, stated, "Aligning ourselves with Perma-Fix, enables ADA to implement our breakthrough technologies with the support of one of the foremost waste treatment companies in the U.S. Importantly, we foresee tremendous opportunity for future technologies, which we are currently developing in cooperation with Perma-Fix." ADA Technologies, based in Littleton, Colorado, is a leading developer of commercial environmental technologies, which assist with waste cleanup and resource conservation.
