Latex Based Paint
Latex based paint is not accepted at the Household Hazardous Waste Site or by Keep Northern Illinois Beautiful.
First off, CALL YOUR TRASH HAULER on how to properly dispose of latex paint. You will need a work order created by them in order for them to pick up that paint. You will need to dry it out using an absorbent such as kitty litter or a paint dry product specifically to be used to dry paint. Do NOT use a quick dry cement. Your trash hauler will tell you what they require before they can pick it up.
Oil based paints and paint thinners:
Oil based paint, paint thinners and other solvents should never be emptied onto the ground where they will contaminate the soil and leach into the groundwater. These items can only be taken to the Household Hazardous Waste Site for safe disposal. They will NOT take any other kinds of paint, or leaking paint containers.
In response to lead-based paint (LBP) concerns, the Illinois Environmental Protection Agency (IEPA) has prepared an information package which outlines those LBP removal approaches which IEPA recognizes as being consistent with protecting human health and the environment. This site does not accept empty, dry or leaking paint containers
