typical methods of hazardous waste storage and disposal include
Typical methods of hazardous waste storage and disposal include:

:

  • surface impoundments (storing it in lined ponds),
  • high temperature incineration (controlled burning),
  • municipal and hazardous waste landfills (burying it in the ground),
  • deep well injection (pumping it into underground wells).

More promising methods focus on minimizing waste,reusing and recycling chemicals, finding less hazardous alternatives.
