As a generator of hazardous waste, Rutgers University is required by the Environmental Protection Agency to implement waste minimization techniques. The goal is to reduce the volume and/or the toxicity of hazardous waste generated. Please read the information below on the specific types waste minimization.

If you have questions regarding waste generated in your studio, please contact your campus specialist at REHS 848-445-2550.

Chemical Reuse
Unused and unopened chemicals being disposed of as waste, due to a change in research or discontinuation of a specific research protocol, will be redistributed to other laboratories that can utilize the chemical. Sharing unused chemicals will reduce the amount of chemical waste generated. Specific applicable chemicals (typically stable compounds with a long shelf life) will be picked up by REHS and segregated in the ESB. These chemicals are cataloged on a list, which is available on our web page.

Materials Available for Reuse / Redistribution List (pdf) 

Please contact the REHS Environmental services group at (732) 445-1828, for delivery of a chemical for reuse from this list. The Environmental Services Group will deliver the chemical(s) to your laboratory. Chemicals being redistributed will be tracked on a spreadsheet by REHS.

Inventory Control
Each laboratory is encouraged to maintain an appropriate inventory of chemicals in their laboratory as a method to reduce unnecessary purchase and disposal. The following methods can reduce the amount of chemicals in a laboratory and minimize waste generated from expired or unwanted excess chemicals:

  • Check your laboratory inventory and the REHS chemical redistribution list before ordering.
  • Purchase smaller containers of chemicals or fewer containers of chemicals.
  • Avoid purchasing larger quantities of chemicals to save on raw material costs. (Chemical disposal costs are often much higher than the initial purchase cost.)
  • Do not accept icfreeló samples from chemical manufacturers, unless you are certain that you will be using the materials. (Again, chemical disposal costs are often much higher than the initial purchase cost.)
  • Rotate stock of chemicals in the laboratory to ensure the older chemicals are used before the newer chemicals

Substitution of Less Hazardous Chemicals
In some instances, chemicals that are more environmentally friendly may be substituted for traditionally used chemicals.


Propylene glycol

instead of

Ethylene glycol

Ethyl alcohol

instead of

Methyl alcohol

Alcohol thermometers

instead of

Mercury thermometers

Alconox, Pierce RBS35 and Nochromix

instead of

Chromic acid cleaning solutions

Detergent and hot water

instead of

Organic solvent cleaning solutions

This Hazardous waste policy is designed to provide guidance for everyone at Rutgers University regarding the proper disposal of hazardous waste. If anyone has additional questions regarding hazardous waste disposal they are encouraged to contact the Environmental Services Group in REHS at (732) 445-2550.
