Chemical Reuse and Exchange Program

The Chemical Reuse and Exchange (REX) Program is a service of the University of Massachusetts, Amherst Department of Environmental Health and Safety (EH&S). Our goal is to reduce the costly disposal of still useful chemicals and supplies. If you are currently a registered user of the Chemical Environmental Management System (CEMS), a list of available materials can be found in CEMS Surplus Chemicals Listing. If you have chemicals which are excess or unneeded, but are still useful (i.e., uncontaminated), have a reasonable shelf life remaining, and are of sufficient quantity to be useful to someone else, please complete the online Hazardous Waste Pickup Request.


This program is restricted to the University of Massachusetts community. While EH&S attempts to verify the purity of chemicals in this program, no guarantee is possible.
