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

Textiles and cardboard are included in the above waste figures.

Not include are: refrigerants, lab chemicals, batteries, fluorescent lamps, construction and demolition waste. These items have been recycled but not quantified.


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

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?:
Yes

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

Average contamination rate for the institution’s recycling program:
16

A brief description of any recycling quality control mechanisms employed:

The key quality control mechanism we employ to minimize contamination is to provide tours of the sorting facilities that accept our materials and visually show the contamination. Another deterrent is spreading the word across campus that all recyclable material from campus is hand sorted in our rural location. Making the connection to human hands discourages our major contaminant, food waste/residue and minor contaminants that pose danger, such as glass and sharps.


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

In addition to frequent MRF tours, we use signage at bins, at recycle dumpsters, as hall flyers and on residential hall magnets. We have found that clustering bins changes behavior in that less contamination is found in clustered recycle bins and less recycling is found in clustered trash cans.


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

In spring 2019, students replicated a 2013 OSU waste stream analysis with 6 campus buildings. They found the recycling rate, contamination rate, and compared these across campus. Then they proposed practical ideas for how to increase the recycling rate and decrease the amount (volume and weight) of trash that OSU sends to the landfill each year.


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

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

The Office of Asset Management assists university departments in effective management and accountability of University property. The Office issues a monthly list of surplus items and whatever items are not moved among University departments or other State agencies are transferred to the Surplus Warehouse where they are displayed for OSU employees to take for use on campus as needed. When the Warehouse is too crowded, usually once per quarter, items are sold at public auction.


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

Faculty, staff and graduate students are strongly encouraged to procure used furnishings, equipment, electronics and other goods from the surplus warehouse. Photos of surplus items are shared via social media and in-person presentations. There is also a webpage dedicated to the exchange of surplus. Several residential halls utilize Buy-Sell-Trade exchanges that they create via GroupMe.


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

Library and computer lab printers are set on default to print double-sided.


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

OSU offers course catalogs, course schedules and directories online. The student newspaper, the O'Colly is online as are departmental newsletters. The University Imaging Office scans files for offices that wish to go paperless. All classes have the option to submit assignments online rather than in person.


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

A Move-In Recycling program was implemented for the first time in August 2013 for students living in both Single Student Housing and Family and Graduate Student Housing. Cardboard continues to be collected for recycling each year at move-in. Real Pokes Pass It On is a Move-out program that collects clothing, books, and household items and donates them to charity either directly or via a fall resale program. Family & Graduate Student Housing also holds a yard sale. Various groups hold book drives at the end of each semester.


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

Many materials are recovered and reused on campus at the departmental level including used office supplies, sturdy boxes, textiles, rags, bricks and pavers, pallets, lab chemicals, corrugated plastic signs, and scrap lumber.
