Regulated Waste FAQs
Equipment must be collected as universal waste if the equipment contains circuit boards or computer components and it was used to store or transfer data or if the equipment was used for entertainment purposes such as a television, radio or cell phone.
Regular alkaline batteries no longer contain mercury and can be safely disposed of in the normal trash. As of April 2009, changes to the shipping regulations require that each battery being transported for recycling must be placed in its own plastic bag or taped on each end prior to pick up. Because of this change, EHS has discontinued its collection bucket program. Alkaline batteries can either go in the normal trash or be collected for removal through EHS. If collected through EHS, the alkaline batteries must be taped or bagged. All other batteries must be recycled. These include lead acid, lithium, rechargeable and button batteries. These batteries cannot be discarded in the normal trash. Batteries will not be removed unless packaged in accordance with these requirements.
Fluorescent lights and the ballast boxes found in the light fixtures cannot go in the normal trash. This also includes the UV lamps found in the biosafety cabinets. To have the fluorescent or UV lights and/or ballast boxes removed, please complete a Universal Waste Pickup Request. If you find them in trash containers or in areas where they need to be removed, please call 203-432-6545 and EHS will arrange for their proper disposal.

Triple rinse containers that are empty and deface the label. Glass bottles should then be placed in a plastic bag and put into any cardboard box. The box should be sealed and the words “broken glass” written on the top. It can then be placed with your normal trash for removal by custodial services. Any container that once held P-listed or acutely hazardous chemicals must be tagged as hazardous waste and cannot be triple rinsed.
All biological and chemical waste tags can be found in either the SHM, KBT or West Campus Resource Center stockrooms. All radioactive waste requests are submitted through EHS Integrator. When you submit a request, the system automatically generates a completed waste tag to attach to waste containers.
