Water-based or Latex paints are made up of water, pigments and an emulsion resin. They do not have hazardous characteristics, are generally non-toxic, and are not a hazardous waste. Before disposing, paint should be solidified with a hardener, by air-drying the open can until it is solid, or painting newspaper sheets before discarding in the trash. Liquid paint in garbage trucks can build up on mechanisms in the truck and soil streets.

Solvent-based paints, also called oil-based and alkyd paints, contain oils and solvents that are toxic and flammable. These paints can contaminate drinking water supplies and groundwater if released into the environment. They are considered a hazardous waste, and should be returned to your local Household Hazardous Waste Collection site for proper disposal.
