Operations on campus—in labs, shops and other locations—generate surplus materials and unwanted chemicals. The Environment, Health & Safety department provides guidance on how to handle these materials and is responsible for the pick-up of surplus materials and hazardous waste. If you have questions about unwanted material that you think should not go into the normal trash, consult the Guidelines for Unwanted Material Disposal in the Recyclopedia. Note that computer equipment, reusable labware, and lab equipment can be collected by UW–Madison’s surplus department, SWAP.
