    • Do not mix organic wastes with inorganic wastes.

120.00 Costs

Generally there is no charge for hazardous waste disposal. It is an essential service that supports teaching, research, and operation of the university. However, chemical users have the responsibility to purchase and manage chemicals. They will be charged for unusually dangerous or expensive disposal problems resulting from unwarranted purchasing or excessive quantities of chemicals or poor management/storage of chemicals.


  • Emergency tapping and venting of a large gas cylinder costs up to $15,000.
  • Peroxide forming compounds that cannot be shipped may require detonation.
  • Disposal of excessive amounts of highly reactive materials.
