Water-based paints such as latex paint are non-hazardous and can be disposed of in regular trash with the lids off. You must dry out the paint before disposing this way by opening the lid and allowing it to air dry. You can add sand or kitty litter to speed up the process. Oil based paints are considered hazardous and must be disposed of properly either on our annual hazardous waste collection day, or at a private hazmat facility.  These facilities can be found in the yellow pages of your phone book.
