Parts 1 and 2. Waste per person

Figures needed to determine total waste generated (and diverted):

	Performance Year	Baseline Year
Materials recycled	125.45 Tons	0 Tons
Materials composted	391.96 Tons	179 Tons
Materials donated or re-sold	184.18 Tons	14 Tons
Materials disposed through post-recycling residual conversion	0 Tons	0 Tons

Total waste generated	1,068.16 Tons	953 Tons

If reporting post-recycling residual conversion, provide:

A brief description of the residual conversion facility:

---

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Period	Jan. 1, 2022	Dec. 31, 2022
Baseline Period	Jan. 1, 2012	Dec. 31, 2012

If end date of the baseline year/period is 2004 or earlier, provide:

A brief description of when and why the waste generation baseline was adopted:

Many of these numbers come from the recycling report to the PA DEP each year. Other numbers are collected through facilities, ITS, grounds, and maintenance. The number for the performance year was gathered in the fall of 2022 as a part of the annual waste characterization study. Baseline year numbers for 2012 were used as a point of comparison in the waste characterization study.

Total materials disposed is was derived from the 2022 Waste Characterization Study diversion rate estimates, as we did not have a consistent tracking methodology with our waste hauler. However, starting in late 2022 and finishing in 2023, we process all waste through on-campus compactors that allow us to obtain precise measurements of waste. This will be reflected in future STARS reports.

Materials donated or re-sold includes clothing, textiles, furniture, and furnishings

Figures needed to determine "Weighted Campus Users”:

	Performance Year	Baseline Year
Number of students resident on-site	1,548	1,443
Number of employees resident on-site	13	0
Number of other individuals resident on-site	9	0
Total full-time equivalent student enrollment	1,696	1,552
Full-time equivalent of employees	908	713
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	2,352.25	2,059.50

Total waste generated per weighted campus user:

	Performance Year	Baseline Year
Total waste generated per weighted campus user	0.45 Tons	0.46 Tons

Percentage reduction in total waste generated per weighted campus user from baseline:

1.87

Part 3. Waste diverted from the landfill or incinerator

Percentage of materials diverted from the landfill or incinerator by recycling, composting, donating or re-selling, performance year:

65.68

Percentage of materials diverted from the landfill or incinerator (including up to 10 percent attributable to post-recycling residual conversion):

65.68

In the waste figures reported above, has the institution recycled, composted, donated and/or re-sold the following materials?:

	Yes or No
Paper, plastics, glass, metals, and other recyclable containers	Yes
Food	Yes
Cooking oil	Yes
Plant materials	Yes
Animal bedding	No
White goods (i.e. appliances)	Yes
Electronics	Yes
Laboratory equipment	No
Furniture	Yes
Residence hall move-in/move-out waste	Yes
Scrap metal	Yes
Pallets	No
Tires	Yes
Other (please specify below)	No

A brief description of other materials the institution has recycled, composted, donated and/or re-sold:

A substantial amount of furnishings was donated and resold as we transitioned out of our old dining hall into the new building.

All of the utensils and containers used by our dining services vendors across campus are compostable (Greenware). Clothing and dorm furniture is also frequently donated and resold (without charge) to our free store at the end of school years for the use of other students in future semesters.

Optional Fields

Active Recovery and Reuse

Materials intended for disposal but subsequently recovered and reused on campus, performance year:

---

Recycling Management

Does the institution use single stream recycling to collect standard recyclables in common areas?:

Yes

Does the institution use dual stream recycling to collect standard recyclables in common areas?:

Does the institution use multi-stream recycling to collect standard recyclables in common areas?:

Contamination and Discard Rates

Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

Compost contamination is directly sorted by student workers; recycling contamination rate has gone dramatically down since education efforts of the general campus have increased.
Formalized waste sort trainings during orientation and uniform signage has had a striking impact on the contamination rates in compost and recycling.

Programs and Initiatives

A brief description of the institution's waste-related behavior change initiatives:

"The College’s Zero Waste Working Group leads the College’s operational and educational efforts to achieve our waste targets. In the 2016-2017 academic year, the Zero Waste Working Group commissioned an initial report to summarize the status of campus integrated waste management.

In June 2022, Swarthmore College formally adopted the 2022 Zero Waste Plan, which establishes new goals for becoming a zero waste campus by 2035. The plan lays out strategies and priorities for achieving these goals by cultivating a culture of zero waste on campus, reducing our per capita waste consumption, and diverting as much recycling and compost away from our trash as possible."

A brief description of the institution's waste audits and other initiatives to assess its materials management efforts and identify areas for improvement:

The College now hosts an annual waste audit that samples waste over several days from ~6 campus buildings. We aim to make this a fun community event each fall, with music, activities, and a variety of educational opportunities. Other waste audits of buildings occur throughout the year as requested/determined.

A brief description of the institution's procurement policies designed to prevent waste:

President's Sustainability Research Fellows and Green Advisors have led the development of policies to prevent waste. An ITS Printer Policy was informally instated in 2019. A Food Catering policy was implemented through Dining Services in 2022, and Events Managment updated their Green Events Guide in 2023. To date, these have only been informally implemented. https://www.swarthmore.edu/purchasing-office/sustainable-purchasing

A brief description of the institution's surplus department or formal office supplies exchange program that facilitates reuse of materials:

In 2021, green advisors spearheaded an effort to establish used packaging drop-offs that the community can then make use of when shipping or mailing items.

A brief description of the institution's platforms to encourage peer-to-peer exchange and reuse:

A brief description of the institution's limits on paper and ink consumption:

All printing is set to double sided default settings. When printing posters or anything with colored ink in the Media Center, students must release their prints and are limited to the amount they are able to print.

A brief description of the institution's initiatives to make materials available online by default rather than printing them:

The College directory and course schedules are only online. Course catalogs are available online through the Registrar's Office website. All printing for public printers is set to a default setting to print double sided.

A brief description of the institution's program to reduce residence hall move-in/move-out waste:

The Worthmore Free Store is a donation-based enterprise that provides access to room furnishings and other supplies for students who may otherwise face cost or transport barriers in obtaining such items. Community members are able to donate or select items throughout the year during store hours, but most donations occur during spring move-out. Worthmore offers a large-scale collection program in the last few weeks of the semester. In the fall, Green Advisors play a key role in move-in waste management through both educational efforts (e.g., sessions during New Student Orientation) and operationally with short-term specialized recyling dumpsters provision.

A brief description of the institution's programs or initiatives to recover and reuse other materials intended for disposal:

There are unofficial buy and sell groups across different social media platforms in which used furniture, clothing, and other appliances are exchanged between students.
