The U.S. Environmental Protection Agency (EPA) has identified many leftover/unused household products as hazardous waste. This list includes such things as:
A waste product that is ignitable, reactive, corrosive, or toxic is considered a Hazardous Waste. Such wastes can catch fire, react or explode under certain circumstances, or be corrosive or toxic; therefore, they need to be disposed of properly, not down the drain! For more information on Household Hazardous Wastes, please visit EPA’s website.
