What We Know: 

Both latex and oil-based paints pose environmental threats when disposed of improperly. Collection and proper management of these products is important for environmental protection.

Oil-based paints are combustible, contain organic solvents, and are classified as hazardous waste when disposed. The presence of hydrocarbon and oxygenated solvents, such as toluene and glycol ethers, render oil-based paints combustible and present an environmental and human health hazard. Consumers are also discouraged from trying to dry oil-based paint for disposal since the evaporating solvents can increase risk of fire, contribute to indoor air pollution, and present an inhalation hazard to humans.

Oil-based paint should never be poured down a drain, or dumped into sanitary or storm sewers – doing so could cause problems at wastewater treatment facilities or pollute groundwater, rivers and streams.

While latex paint does not typically exhibit characteristics of a hazardous material, some latex paints contain solvents, biocides, and other materials of concern. Liquid paints are often banned from landfills because they can contribute to leachate. Improperly disposed paint can contaminate groundwater, and harm fish and other aquatic life.

Post Consumer paint is the single largest source of Household Hazardous Wastes (HHW) generated in this state, and its disposal in the solid waste stream is prohibited. Paint represents 35% of the HHW collected by local government HHW programs. In 2006, over 2 million gallons of paint were collected in CA, at an average cost to of $8 per gallon – over $16 million total to local programs annually. It is important to come up with  solutions to help these struggling HHW to take care of post consumer paint.
