Hazardous Waste Disposal Procedures

The DEHS Regulated Waste Division provides chemical waste pickup and disposal services at no cost to University of Minnesota departments. To have chemical waste picked up from your work area, follow the chemical waste pickup procedures listed below:

  1. Chemical waste must be placed in an appropriate container and kept closed at all times except when adding or removing waste. Liquid waste containers must be stored in secondary containment (e.g., tub, tray, bucket) as illustrated in Figure 1. 
  2. Chemical waste containers must be labeled with the words “Hazardous Waste,” an accurate description of the waste, the primary hazard(s) associated with the waste, and a start date. UHS recommends that the label illustrated in Figure 2 be used (contact DEHS to receive these labels free of charge). 
  3. Submit waste using Chematix, which is the University of Minnesota’s online chemical waste pickup system. Visit the CHEMATIX homepage linked below and click the “Waste” tab for detailed submission instructions.

Sink and Trash Disposal Procedures

No chemical waste should be poured down the drain or discarded in the trash unless it is certain that doing so does not violate waste disposal regulations. In order to ensure improper disposal does not occur, please contact UHS (hazwaste@umn.edu) to seek permission to dispose of nonhazardous chemical waste in the sink or trash.   

If you have questions, contact DEHS at 612-626-1604 or hazwaste@umn.edu.
