Perma-Fix Purchases Mercury Amalgamation Process Rights

ATLANTA, April 26, 2011 (GLOBE NEWSWIRE) -- Perma-Fix Environmental Services, Inc. (Nasdaq:PESI), a leading provider of nuclear waste services, today announced the purchase of two mercury treatment technologies from Mercury Control Technologies, LLC, a Colorado-based company. The first patented technology is for mercury amalgamation, which is the U.S. Environmental Protection Agency (EPA) required treatment method for radioactively contaminated elemental mercury. The second patented technology is for mercury stabilization, which is the EPA required treatment method for other chemical forms of mercury. The application of these treatment technologies ensures that radioactive mercury contaminated wastes meet EPA's Land Disposal Restrictions for safe disposal. 

Prior to acquiring these technologies, Perma-Fix had been using these processes to treat U.S. Department of Energy (DOE) radioactive mercury contaminated waste since 2002 through a licensing agreement. Perma-Fix is one of only two companies to own the rights to a proven technology for the treatment of radioactively contaminated mercury.

Since the 1950's, mercury has been widely used throughout the DOE weapons complex, resulting in a large amount of legacy waste awaiting treatment. As DOE continues its mission to clean up Cold War sites across the U.S., there is a need to safely and efficiently treat this waste for disposal. Mercury contaminated waste is one of the most difficult waste streams to treat due to the complexities of the different matrices (soil, debris, liquid elemental mercury, etc.) and the regulatory requirements for treatment. 

"As owners of these patents, Perma-Fix will be able to expand our mercury treatment capabilities for DOE's inventory of radioactively contaminated mercury as well as provide these capabilities to other market segments. This will strengthen our strategic position to remain the leading treatment provider for challenging waste forms, and provide our clients with solutions to their waste management challenges," stated Dr. Louis Centofanti, President and CEO of Perma-Fix.
