Minimizing Waste

Penn is dedicated to improving our waste stream through a host of efforts. Visit the Minimizing Waste page on the Facilities & Real Estate Services website.

Download colorful signage for recycling, compost, and landfill (in PDF format) from the Waste Management page on the Facilities & Real Estate Services website.

Students — Email sustainability@upenn.edu to find out about any bin giveaways. Bins may also be purchased through Penn Student Agencies.

Staff & Faculty — Contact your Building Administrator or your Sustainability Coordinator to request a recycling bin.

This off campus recycling guide, created by the Undergraduate Assembly, explains what can be recycled, how to obtain a bin, and what day recycling is picked up.

The Philadelphia Streets recycling page has more information about the city's recycling system.

Since September 2010, Penn has used a single-stream recycling system. This means that all recyclable materials (mixed paper, cardboard, glass, metals, and all plastics) can be placed together in the same container.

Some areas on campus may still have separate bins for “mixed paper” and “plastic/glass/aluminum,” but all recyclables can go in those bins.

Note: Styrofoam and plastic bags/wrap cannot be recycled, and should be placed in trash bins.

Penn recycles plastic containers (numbered or unnumbered), and utensils. Penn does not recycle Polystyrene (Styrofoam), packing materials such as bubble wrap and packing peanuts, or plastic wrap and bags.

The Fresh Grocer located at 40th & Walnut and the CVS stores located at 40th & Walnut and 34th & Walnut have collection bins for plastic bags.  Visit Green Philly for more information on where you can recycle plastic bags in the city.

All campus dining halls collect kitchen waste for composting. Hill College House, King’s Court College House, Class of 1920, and Houston Hall provide compost bins for diners to dispose of food waste. Joe’s Café in Steinberg Hall-Dietrich Hall and the Hillel dining hall also compost food waste.

The Annenberg Public Policy Center building has a worm bin for waste and leftovers from staff meals. Mayer Hall has a composting bin for residents’ food waste. The Law School composts leftover food from events and receptions. Koo Plaza (2nd Floor) of Huntsman Hall has a compost bin for food waste. Additionally, Kelly Writers House, the School of Veterinary Medicine, and the School of Dental Medicine all have programs to collect and compost food waste. An increasing number of schools and centers are also holding green events that include a compost option.

Penn is converting many large-scale events to Zero-Waste in order to reduce the amount of waste going to landfills. At Zero-Waste events, such as the Family Welcome Picnic, the Convocation Dessert Reception, and the Athletic Picnic during New Student Orientation, 90% of waste is composted or recycled.

Furthermore, in the spring of 2018, a composting collection in the Harrison College House Community Garden (located on the pathway between Harrison College House and the LGBT Center) launched. The program is available to any Penn members interested in composting their food waste. Please visit the Bennett Compost website for a list of accepted items. For more information, please contact sustainability@upenn.edu.

Conserving Energy

Most of the larger buildings at Penn are heated and cooled through the use of an air handler. The basic function of an air handler is take in outside fresh air, condition it (heat or cool) and supply the fresh air to the building while exhaust air is discharged. Depending on the required temperature of the conditioned air, the fresh air is either heated by a heating coil, or cooled by a cooling coil. During the cooling season. there is the additional need to reduce the humidity in the fresh outside air. This is accomplished by cooling the air down to 55F which causes the moisture in the air to condense on the cooling coils, so it can be removed. The cooled air is too cold to discharge directly, so it then passes through a heating coil called a reheat. The reheat warms the air back up to a temperature that is comfortable for the building occupants. To conserve energy, the systems are set to a supply air temperature of 68-72F. This minimizes the amount of reheat energy needed. Increasing thermostat settings calls for the air handler to increase the amount of reheat, which uses more energy. Hence, a cooler set point for a building with an air handler actually conserves energy.

Learn more about Penn’s energy conservation practices on our Conserving Energy page or the Energy Management page on the Facilities & Real Estate Services website.

Penn is committed to keeping its campus safe, and lighting is one of the best deterrents for crime. Thus, in addition to internal lighting required by fire safety code in Penn building corridors, staircases, and office spaces, many lights at building perimeters remain lit throughout the night to help illuminate walkways and sidewalks to ensure the safety of pedestrians, cyclists, and other members of the Penn community. To conserve energy and reduce greenhouse gas emissions, Penn has upgraded the lamps in all outdoor pedestrian lights (the familiar “acorn” lampposts) to LED, reducing electricity consumption as well as the need for frequent bulb replacement.  General campus flood lighting, such as that used at Shoemaker Green, College Green, and the 38th Street Bridge, use high efficiency LED or conventional lamps. 

Initiate a Service Request on the Facilities & Real Estate Services website. You can also contact your Building Administrator to investigate the issue.

Sustainable Transportation

Penn has updated its Bike Policy. View this article for more information.

View a map of bike lanes and more on the Facilities & Real Estate Services website.
