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

Materials intended for disposal but subsequently recovered and reused on campus, performance year (e.g. materials that are actively diverted from the landfill or incinerator and refurbished/repurposed) :
---

Does the institution use single stream recycling (a single container for commingled recyclables) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
Yes

Does the institution use dual stream (two separate containers for recyclables, e.g. one for paper and another for plastic, glass, and metals) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
No

Does the institution use multi-stream recycling (multiple containers that further separate different types of materials) to collect standard recyclables (i.e. paper, plastic, glass, metals) in common areas?:
No

Average contamination rate for the institution’s recycling program (percentage, 0-100):
---

A brief description of any recycling quality control mechanisms employed, e.g. efforts to minimize contamination and/or monitor the discard rates of the materials recovery facilities and mills to which materials are diverted:
---

A brief description of the institution's waste-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

In recent years, the college has taken on a number of waste-related behavior change initiatives. The figures above are from 2013-14 and further back, but from 2016-18: (1) the Hixon Center has administrated multiple waste audits on campus to involve the community in measuring waste and ascertaining how successful we've been in diverting waste from landfill; (2) we have aggressively implemented composting on campus, which has included installing a dehydrator in our dining hall, implementing pre- and post-consumer waste composting in the dining hall, and installing table-top and external compost bins across campus. These have all been accompanied by signage, educational blog posts, and messages to the campus community.


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

Within the past couple of years, we've held a couple of campus-wide waste audits that take representative samples from different building types (academic, administrative, residential, dining) to ascertain how well we are doing in terms of diverting waste from landfill, and how much waste we are producing overall.


A brief description of the institution's procurement policies designed to prevent waste (e.g. by minimizing packaging and purchasing in bulk):
---

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

Most of this work is done informally on campus. Staff and faculty oftentimes exchange supplies directly, and the campus has not yet instituted the means to measure these transactions as diversions from landfill. In addition, most items that may typically get thrown away as old office supplies are sometimes taken by the campus community or external visitors, for which the campus has also not yet instituted the proper means to measure that reuse.


A brief description of the institution's platforms to encourage peer-to-peer exchange and reuse (e.g. of electronics, furnishings, books and other goods):

As mentioned, this all happens pretty often and informally on campus. It often occurs through e-mails to the campus community promoting the giveaway of items when they are no longer needed. In addition, Facilities & Maintenance holds a giveaway of lost items that were never claimed at least once a year.


A brief description of the institution's limits on paper and ink consumption (e.g. restricting free printing and/or mandating doubled-sided printing in libraries and computer labs):
---

A brief description of the institution's initiatives to make materials (e.g. course catalogs, course schedules, and directories) available online by default rather than printing them:
---

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

Up to this point, students have been provided plentiful options in terms of discounted off-campus storage. In addition, there are designated storage spaces in the residence halls where returning students are able to leave behind their items and retrieve them the next year. In these situations, we are able to reclaim most left-behind items or limit the number of move-in/move-out waste.


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

Additional documentation to support the submission:
---

The campus was able to substantially reduce materials disposed in a solid waste landfill or incinerator between the baseline and performance year largely due to a few key developments: (1) vastly improved recycling facilities on campus, which include cardboard balers, increased presence of recycling bins, and reduced disposable recyclable material for purchase from campus vendors; (2) the development of a campus-wide compost program to reduce organics and food waste otherwise going into landfills; and (3) increased awareness around waste reduction and sustainable practices on campus.
