All of our campus "all you care to eat" dining halls collect kitchen waste for composting, including Hill, King’s Court, 1920 Commons, Lauder, and Houston Market.
Penn is converting many large-scale events to be low-waste events in order to reduce the amount of waste going to landfills. At low-waste events, such as the Convocation Dessert Reception and the Athletic Picnic during New Student Orientation, as much waste as possible is diverted from the landfill by being composted or recycled. If you are interested in hosting a green event, check out our Green Events Guide.
A composting collection is located in the trash corral behind Mayer Residence Hall at 39th and Spruce Streets (see map below). The program is available to anyone in the Penn community interested in composting their food waste. The specific items accepted at this location can be found in the graphic linked here and below.
For more information, please contact firstname.lastname@example.org (link sends e-mail).
To find out where you can drop off items like eyeglasses, shoes, and writing utensils on campus, see the Special Recycling and Reuse Collections page. For any other items, check out earth911 (link is external).

A Goodwill donation box is located on campus year-round at Rodin College House. Each May during PennMOVES (link is external), an organized collection takes place across campus under the direction of Business Services.
Clothing and accessories that are in good condition and are in style can be taken to Penn Closet, a student-run thrift store located in Williams Hall, or donated to other local consignment shops.
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 cannot be recycled and should be placed in trash bins.
Most Schools are participating in electronic waste recycling. See more information on the Special Recycling and Reuse Collections page. If your School is not currently participating, you can contact Elemental (link is external) or E-Force (link is external) directly to collect and dispose of these items.
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 expected commercial operation date is the end of 2022, so we expect to see power in 2023.
- Johns Hopkins - 175 MW
- Stanford - 67 MW
- MIT - 44 MW
- Georgetown - 32.5 MW
- Harvard - 12 MW
In terms of the Pennsylvania region, many of our peers have signed PPAs as well, but again, Penn’s is by far the largest.
- Penn State - 70 MW
- Partnership between Lehigh, Lafayette, Muhlenberg, and Dickinson - 45.9 MW
- University of Pittsburgh - 17 MW
Penn will be exploring opportunities for this project to be utilized by the student body for research purposes once the facilities are constructed and does not yet have any specific plans.
PENN’s primary commitment was to create additionality of alternative energy production. Over the 25-year contract, the rates are competitive with projected conventional electricity prices.
This project will be a 220 Megawatt (MW) solar power project that will cover about 1,600 acres in Central Pennsylvania. This system is expected to generate approximately 450,000 Megawatt-hours of electricity per year. This is enough energy to power approximately 43,000 homes.
Penn is procuring power from Community Energy and will not be involved in operation or maintenance of the facility. Any job training is outside of our purview.
Community Energy anticipates that this project will require 150 full-time equivalent positions during construction and ten (10) full-time equivalent positions during operations.
The project is expected to have a 35-40 year life. The project will be decommissioned at the end of its life. The steel posts that support the racking structure that hold the panels are pounded into the ground with no concrete footers so they can be fully removed at the end of the project’s life. Steel and aluminum parts are expected to be recycled. Solar panels are more than 80% glass and aluminum, so recycling of the panels is expected as well. The solar panel recycling industry is in its early stages of development as the vast majority of panels manufactured are still in operation. There are facilities in the US and abroad, and we expect solar panel recycling to grow as more and more panels are decommissioned.
A solar power purchase agreement (PPA) is a financial agreement between a solar project developer and customer. The developer agrees to design and build the system while the customer agrees to purchase the power generated by the system. In this case, the University of Pennsylvania (Penn) has agreed to purchase solar electricity from Community Energy, the developer.
We do not have plans for another PPA at present. We are currently focusing on reduction of energy consumption on campus, which will reduce what we need to buy from the grid. Additionally, Penn has a goal of carbon neutrality by 2042. We are currently assessing a variety of avenues to achieve that goal.
The project will put Penn on a solid path to its goal of carbon neutrality. The project will offset 166,000 MTCE per year. These benefits were seen as optimal for Penn’s desire to address carbon emissions in mitigating the effects of climate change. Other potential impacts were considered but not included in the analysis.
There is always going to be market risk of market prices falling below our locked in price. In response to these concerns, we analyzed various scenarios that used current forward market pricing to evaluate the market risk over 25 years. The results showed a low level of risk for market prices to drop below our contracted price over the life of the PPA, well within the accepted levels for the University.
Environmental studies are underway. Wildlife, critical habitat, wetlands, and cultural resources assessments are in process.
Penn has assessed the available roof space on campus and determined that there is not enough space on campus to develop a sizable solar capacity.
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.
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.
