Latex Based Paints
Latex based paint is not hazardous and should be thrown away with regular waste when it is completely solid/dried - this does not apply to oil based paint. Paints should not be dumped down any drains (home, municipal, etc.) as they cause problems with pipes, waste water systems, and water quality.
To dry latex based paint you can simply leave the lid off and let the paint dry completely, or for larger quantities, line a large box with a plastic bag, pour the paint into it (to increase the surface area for drying), and add an absorbent material such as cat litter. When you throw it away, leave the lid off to show waste service workers that it is completely solid/dry.
If you have a usable and larger quantity we suggest checking with local organizations for potential donation. For example: churches, school theater groups, etc.
Oil Based Paints
Oil based paints are considered household hazardous waste and need to be disposed of at a household hazardous waste collection event. Visit our Household Hazardous Waste page to find more information.
Spray Paint Cans (Aerosols)
Spray paint cans (aerosols) that have contents are considered household hazardous waste and need to be disposed of at a household hazardous waste collection event. Visit our Household Hazardous Waste page to find more information.
If completely empty spray paint cans (aerosols) should be thrown away with regular waste or recycled if possible. These cans are often not accepted through curbside and/or drop-off recycling programs, so be sure to check with your individual waste hauler, recycling center, or scrap metal processor prior to recycling these empty cans.
