Mixed Hazardous Waste

Definition: Waste with hazardous constituents, which may include radioactive materials, infectious agents and/or hazardous chemicals

Mixed Waste Examples:

  • Radioactive waste with trace levels of chloroform or toxic heavy metals
  • Liquid radioactive waste containing greater than 22% methanol
  • Liquid radioactive waste containing Chromic or Formic acid
  • Liquid radioactive waste with phenol, chloroform, or formaldehyde
  • Chemical or radioactive waste containing blood or blood products
  • Tissues containing chemotherapeautic drugs (tamoxifen, methotexate, etc.)

General Instructions:

  • Properly identified all hazardous constituents- Use hazard specific labels/tags
  • Minimize the volume produced 
  • Separate liquid and solid waste 
  • Separate aqueous and organic solvents
  • Adjust the pH of waste solutions to between 5.5 and 8.5 
  • Segregate all radioactive mixed waste by isotope
  • Avoid generating mixed hazardous waste to the extent possible
