Facts on Hazardous Waste

Hazardous waste refers to waste that may cause harm to people or the environment, such as pesticides or mercury. Manufacturing processes and some household products produce hazardous waste. The U.S. government regulates the disposal of these toxic materials.

Features

• Hazardous waste is usually corrosive, reactive, ignitable or toxic, according to the Environmental Protection Agency. Corrosive waste, such as acid, eats away at substances. Reactive waste explodes or becomes toxic if combined with other chemicals. Ignitable waste, such as gasoline, easily catches on fire. Toxic wastes are poisonous if consumed or absorbed through the skin.

Significance

• Hazardous wastes can damage the environment by polluting water, air and land. Hazardous wastes can also harm humans and animals who inhale, ingest or touch them. Exposure to hazardous waste can be acute, such as a single burn from battery acid, or chronic, such as drinking contaminated water for several years.

Disposal

• When possible, hazardous waste should be recycled. If recycling is not possible, hazardous waste is usually burned, buried or stored in a lined pond, according to the EPA. If you have hazardous waste, such as paint thinner or old batteries, don't throw them away or pour them down the drain. Instead, contact your local recycling center for information on recycling or legally disposing of the materials.
