MRS's Mercury Removal/Recovery (MR2) Process is a mobile or fixed-site medium-temperature thermal desorption method for removing mercury from a wide variety of solid materials that has been proven to: 

  • consistently reduce the mercury content of the treated material to less than one (1) part per million (< 1 ppm) regardless of the level and form of mercury originally contained,
  • produce a 99% pure metallic mercury suitable for direct refining to high purity metal,
  • recover mercury from compounds such as mercury oxide, mercury chloride, and mercury sulfide,
  • prevent the released sulfur and/or chlorine from entering the process exhaust,
  • operate without generating any secondary liquid, solid, or gaseous secondary waste,
  • produce a gaseous effluent that meets all clean air standards,
  • efficiently treat materials having high moisture contents, and
  • effectively utilize "double containment" for added worker and environmental safety.


Introduced commercially in 1994, the MRS Process has been successful in removing and recovering mercury from a wide variety of materials, including soils, chlor-alkali wastes, copper and precious metals smelting and refining by-products, waste water treatment sludges, catalysts, carbon products, batteries, and fluorescent bulbs. The process has also been demonstrated to be effective in removing mercury from low-level radioactive wastes without removing or dispersing radioactive particles from the material.
