Process for Removal of Halogenated Hydrocarbons


Halogenated hydrocarbons are widely used in flame retardants, electronics, pharmaceuticals, and solvents. The presence of these materials in waste streams continues to be a significant environmental problem. Traditional treatment methods require extensive energy, create toxic by-products, or are incompatible with air or water. 

Researchers at the University of Guelph have developed a novel method to efficiently remove a variety of these of toxic compounds from waste streams at low cost by converting the halogenated hydrocarbons into non-halogenated materials.

Applications and Advantages

  • Solution-based treatment that is compatible with air, water, and organic solvents
  • Demonstrated to be effective for treatment of brominated flame retardants, DDT, halothane, CCl4, CBr4, and most Freons
  • Reducing agent is cost effective and easy to manufacture
  • Solution-based reducing agent facilitates easy handling and transportation
  • Dehalogenation occurs at or slightly above room temperature
  • Reducing agent produces salt for easy removal
