Disposal of Solid Chemicals in the Normal Trash Many solid chemicals can be safety discarded into the normal trash, provided they are in containers that are not broken or cracked and have tightly fitting caps. These chemicals are considered acceptable for ordinary disposal because they display none of the properties of hazardous waste, are of low acute toxicity, and have not been identified as having any chronic toxic effects as summarized in the National Institute of Occupational Safety and Health (NIOSH) “Registry of Toxic Effects of Chemical Substances”. Examples of chemicals acceptable for disposal as regular trash are listed below. To dispose of these chemicals, place the containers in a box lined with a plastic bag, tape the top of the box shut, write “Normal Trash” on the box and then place the box next to the lab trash container. Only solid forms of these chemicals can be disposed in this manner. Any questions about these chemicals or other chemicals that may be disposed of in the normal trash should be directed to the Hazardous Materials Technician (610) 330-5225.
