Leverage Our Extensive Experience with Elemental Mercury Disposition

Mercury of various forms have been widely used throughout the U.S. and internationally, and to date, more than 600,000 pounds of this radioactive waste co-contaminated with mercury have been processed by one of Perma-Fix's many treatment technologies. Perma-Fix has implemented treatment solutions based on available and patented technologies to address these problematic wastes.

Perma-Fix provides effective treatment of radioactive-contaminated elemental mercury via amalgamation, the required treatment method for these wastes. Perma-Fix employs a patented amalgamation process using proprietary reagents that meet the EPA technology treatment standard (AMLGM). This process treats elemental mercury waste to meet the requirement of AMLGM using chemical reagents that bind the mercury and render it non-leachable. Mercury treatment is provided in a dedicated area of the facilities, with its own air handling and filtration system, for treatment of large volume, mercury contaminated wastes (elemental) using a proprietary amalgamation and stabilization process.

Our Experience: Mercury Waste Materials Managed at Perma-Fix Facilities
Waste Type Quantity (Tons) Processing Technology
Elemental Mercury 181 Amalgamation
Mercury-Contaminated Debris 1,050 Mercury Roasting/Amalgamation
Mercury-Contaminated Liquids 5,000 Thermal Processing/Stabilization
Mercury-Contaminated Solids/Soils 10,135 Mercury Roasting/Amalgamation/Stabilization

Two of our four facilities, Perma-Fix of Florida and Diversified Scientific Services, are licensed and permitted to receive, handle and store mercury for up to one year. With over $50 million of investment in facilities and technologies, Perma-Fix offers the most comprehensive low-level radioactive waste (LLW) and mixed low-level radioactive waste (MLLW) treatment facilities available in the U.S. Our experience, capacity, and regulatory compliance history set us apart in the industry. We are continually investing in new technologies to offer the most current state-of-the-art treatment options in the market.
