Hazardous Waste Management
Wastes are defined as materials that are no longer suitable for their intended purpose. This includes materials that are waste products of a procedure, old outdated products that have not been used or new products purchased in excess. If the product or chemical has a hazard warning, such as flammable or combustible, poison or toxic, or dispose of according to all state and federal regulations, you should inquire about appropriate disposal practices before you discard the material. Unless otherwise noted, the waste should be containerized and shipped for disposal.
In general, all of the following substances used in our laboratories or studios should be disposed of hazardous waste: (this list is not complete)
- Partially full spray cans.
- Aqueous solutions, >24% alcohol.
- Cyanide-bearing wastes
- Formaldehyde solutions, > 0.1%
- Heavy metal salts and solutions
- Oxidizing solutions
- Sulfide-bearing wastes
- Chemicals labeled as toxic or poisons
- Kerosene-saturated sawdust
- Acid or base solutions
All hazardous waste activities, including generation, storage, labeling and disposal, must be conducted according to the state statute NR600. Severe penalties may be levied against the generator of the waste, the Hazardous Materials Management Coordinator and/or the Chancellor for intentional or accidental violation of the statute. Waste disposal is conducted only through the University Hazardous Materials Coordinator and the University System Hazardous Waste Disposal Contract.
Wastes may not be intentionally diluted or treated in an attempt to avoid disposal charges. Evaporation or sewering of combustible or flammable liquids or solids is forbidden. Dilution or treatment may result only from a recognized step in the process. (Acid-Base Neutralization and silver recovery are exceptions to this rule.
