Many products should be taken to a household hazardous waste collection site. Properly prepare household hazardous wastes for transport to a collection site. Keep products in original containers when possible. If a product does not have its original label, label it yourself if you are sure of the contents. Don't mix products together.
Dangerous reactions can occur when some materials are mixed.
Make sure products are properly sealed to prevent leaks and spills. If a container is leaking, secure it inside a second leak-proof container. Pack containers in sturdy boxes in the trunk of your vehicle, away from the driver, passengers and pets. Most household hazardous wastes are recycled, reused or burned for fuel recovery after they are collected at an event or facility. The remaining wastes are packaged and shipped to a hazardous waste landfill, such as the one at Arlington, Oregon, where they are buried.
