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?:

Yes

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

Yes

Contamination and Discard Rates

Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

The two key quality control mechanisms we employ to minimize contamination are education and waste stream audits. Every recycling bin has signage that accompanies it to show what is accepted in that specific waste stream, several social media posts each month are dedicated to proper recycling practices, events are held which have recyclable and nonrecyclable materials present to demonstrate proper recycling practices and each year we participate in America Recycles Day to further spread education. We also provide tours of the sorting facilities that accept our materials and visually the life cycle of items that are recycled.

Programs and Initiatives

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

In addition to frequent MRF tours, we have signage located at individual bins, recycling dumpsters, flyers in residential halls, and magnets that are included in each residence hall room. 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:

Every Monday and Thursday a student intern from the Office of Sustainability does a waste audit of the ResLife Recycles program which is our single-stream system. She goes through each recycling dumpster and visually inspects for signs of contamination. In addition, she records what type of contamination was found, if the dumpster should go to a landfill due to the level contamination, and approximately how full it is. She takes notes on each dumpster and uploads them into a data sheet that we use to track which dumpsters are the most commonly contaminated and know to target those for further education.

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' on effective management and accountability of University property. The office issues a monthly list of surplus items and whatever items are not moved amongst 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. Real Pokes Pass it On, is a program where during move-out student volunteers collect gently used furniture that was on its way to the landfill and resell or donate those items back to the student body at the start of the following semester.

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

Library and computer lab printers are set to print double-sided as their default. Ink cartridges that are empty are sent back to the manufacturer to be recycled or reused.

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. Several textbooks are provided online, as well as articles and other materials needed for classes.

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 including used office supplies, sturdy boxes, textiles, rags, bricks and pavers, pallets, lab chemicals, corrugated plastic signs, and scrap lumber.
