latex paint

Latex paint is not considered a hazardous material. To properly dispose of latex paint:

  • Dry it Out and throw it away with your regular trash.
  • For small quantities – pop off the lid and let it dry up or paint it onto waste cardboard.
  • For larger quantities – mix it with clay-based cat litter or sawdust so it is no longer liquid before throwing away the can.
  • Always leave lids off empty, dried out containers.

Alkaline batteries do not need to be disposed of as a hazardous waste. They can be disposed with your regular household trash.
