Chemical Waste Disposal

EH&S is responsible for the management of regulated wastes at Pitt. No lab chemicals or untreated biological wastes should be placed in general trash, flushed down drains or otherwise inappropriately disposed. Contact EH&S at 412-624-9505 or with questions regarding proper disposal procedures.

All regularly scheduled chemical waste pickups and collections have resumed at University buildings/facilities.

Please keep the following COVID-19 Safety and Wellness guidelines in mind when conducting waste drop-off activities:

  • A self-supplied cloth mask or a barrier mask must be worn when outside the lab
  • Maintain social distancing by waiting for an “empty” freight elevator
When a material has no further use and has been declared a waste by the user, it must be clearly labeled as a waste. The proper disposal of waste chemicals at Pitt is necessary to meet our stewardship and regulatory compliance requirements. Environmental Health and Safety is available to provide technical guidance, assistance, and additional information.
Pitt is classified as a large-quantity generator of hazardous waste. Labs must not accumulate chemical waste for more than 30 days before placing it in the applicable University chemical waste pickup area.
Refer to the disposal schedule below for dates and locations of scheduled pickups. The Chemical Waste Disposal Form should accompany the waste at time of disposal.
