Recycling, trash disposal and no-dumping policy

All recycling items must be properly sorted and trash disposed of by the SEAS Receiving Dock staff and SEAS departments per the Environmental Health and Safety (EHS) and University recycling/trash policies currently in place. In this document, the items listed, along with the procedures, are the most common types with which we interact and handle on a daily basis. Princeton University promotes the reuse of all recyclable materials and unconditionally supports a No-Dumping Policy.


To fully enforce this effort, the following recycling/trash procedures are to be followed:

Dumpsters: Five (5) dumpsters are available for usage in the following locations:
(To be used only by Princeton University staff and students. Portable trash items can also be transported to the dumpsters by ENG custodians)

North Garage entrance area (near the bicycle rack and pedestrian path):
Two (2) dark green dumpsters for trash only.
One (1) gray dumpster (labeled) for paper, cardboard, bottles and cans recycling only.

Prospect Ave Apartments parking lot (opposite H-Wing Von-Neumann building):
One (1) dark green dumpster for trash only.
One (1) gray dumpster (labeled) for mixed paper products and cardboard recycling only. Cardboard boxes are to be broken down prior to being discarded.

9-Volt batteries: Cover the terminals (+/-) with electrical/duct tape or place in individual plastic bags prior to placing in trash:

Batteries: Rechargeable



Mercuric Oxide

Contain hazardous metals (Universal Waste) and must be recycled. Batteries must be completely discharged.

Place in the recycling containers labeled “Universal Waste” located in the C119 machine shop or in the hallway next to the loading dock A132 double blue doors. The contact terminals must be covered with non-conductive tape (a roll of duct tape is attached to each container) or place each battery separately in its own sealed plastic bag PRIOR to disposal to prevent short-circuiting or fire hazards during storage and transportation.

Batteries: Lead Acid Place in the blue plastic container labeled “Lead-Acid Battery Recycling” located along the back wall in the recycling fenced area (behind the hydraulic lift gate).
All computers, electronic, office, lab equipment, all types of furniture, etc Surplus items must be empty – remove all items. Contact your department Central Surplus Coordinator(s)
Scrap metals, such as aluminum, copper, steel

Nuts, bolts, screws, etc

Place in the gray dumpster located along the back wall in the fenced area (behind the hydraulic lift plate).
Large scrap metal items Place on ground on the right side in the fenced area (behind the hydraulic lift plate). Only these scrap metal items are to be placed in the fenced area.

Wooden pallets, skids, crates

Neatly place and stack on the ground in the fenced area behind the hydraulic lift plate. Smaller wood pieces can be placed in trash dumpsters..

There are multiple and very visible “NO-DUMPING” signs posted throughout the E-Quad Receiving Dock Area.This area includes all parts connected to, related to and near the dock, including any areas in front, the gas cylinder shed alley behind the dock and the fenced area behind the hydraulic lift gate. There are no areas accessible for dumping. There is never a valid reason for anything to ever be left or DUMPED in the receiving dock area. When items are dumped on the receiving dock, they are in violation of EHS and OSHA Safety policies and guidelines. These items are unsecured, block the pathways which must remain clear at all times to receive your deliveries, become safety issues and prevent us from servicing SEAS departments. Injuries have occurred to staff and truck drivers due to broken glass, exposed nails, sharp objects and slippery liquids from items dumped on the receiving dock areas.

Should anyone have a question regarding the direction to take for the proper sorting and disposing of any item listed in this document or for any and all other recycling, surplus, trash disposal or other items not listed in this document, please contact the SEAS Receiving Dock Coordinator (Phil Curry) or Receiving Dock Staff/Stockroom so we can help provide you with feedback and the simplest option(s) available for your situation.
