A brief description of any recycling quality control mechanisms employed:

We have never had a load of recyclables rejected. Custodial staff are instructed to dispose of items in recycling bins if the majority of the contents are trash/contaminants.


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

Various efforts are incorporated to minimize waste. All incoming freshman are given a reusable water bottle and water filling stations have been installed in every residence hall and across our campus facilities. Our labs are offered a monthly glass blowing service to repair cracked glassware when feasible. All of our Procurement bid documents are electronic. Reusable envelopes are utilized for inter-campus mail.

We do divert many items for reuse/donation but do not have great way to track weights for these items. Our current waste audit and Solid Waste Management Plan will address this issue.


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

A comprehensive waste audit was conducted in 2017, providing a full analysis and composition of our waste, including analysis of waste by building type. These results were used to develop a Solid Waste Management.

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

The following information is included in the current Procurement Policy:

"Northwestern considers environmental impact in purchasing decisions, when appropriate. Procurement and Payment Services (PPS) will consider the use of products and services with less environmental impact than competing products when it is a good best-value decision to do so (based on a thorough total-cost-of-ownership analysis). When establishing contracts and agreements on behalf of the University, PPS considers the initial price as well as the factors listed below. Northwestern also encourages departments/schools to consider the use of products and services that impact the environment less than competing products, when it is a good best value decision to do so.

A good best value decision based on a thorough total cost of ownership analysis considers the initial cost of the item as well as factors such as:

-Shipping Materials. Purchase products that are shipped in containers that are returnable or reusable and made from recycled content (i.e. cardboard boxes). Also request bulk packaging when multiple items are ordered for delivery at the same time.

-Recycled Content. Purchase products made with recycled content suitable for the intended use. Look for a high percentage of post-consumer content. “Post consumer” is material that has served its intended purpose and has been discarded for disposal or recovery by a business or consumer. Other recycled content includes post-industrial wastes, which are by-products of a manufacturing process that would normally not be reused in the process.

-Other. Environmental performance of the supplier and/or producer should also be considered, such as waste prevention, waste reduction, pollution prevention, clean air and water programs, re-use of materials, minimization of scrap material, and any other green factory initiatives, etc. The University strongly desires to minimize the amount of waste sent to landfills. Both the product purchased and the packaging materials associated with it should be minimized to prevent waste as much as possible."


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

The Surplus Property Exchange is an online bulletin board where Northwestern departments/schools can list surplus University property for other departments/schools to purchase or take for free. Available items include computers, furniture, toner, lab supplies and more. Staff can also subscribe to a listserv to receive an email notification when a new item is posted on the Exchange. University employees and students may bid on items for personal use after the item has been listed for more than 30 days.


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

See above


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

All Northwestern University libraries, plus many public areas, labs and classrooms charge for printing. These printing charges encourage responsible printing and reimburse the university for the cost spent on printing materials. Printing is free for students in certain schools, but where free printing is offered, it's in black and white.

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

All course catalogs, directories and schedules are distributed to students online, through department websites and CAESAR, the student academic portal. Students are able to browse classes, course descriptions, course times and comments from previous students through CAESAR.

Our Graduate School went paperless for admissions in 2013. All admissions materials are delivered electronically. The Student Organizations and Activities Office offers financial incentives for student groups to go paperless at information fairs. The Library sponsors Paperless Month every April with targeted messages around reducing printing, utilizing 'print to Pdf' options, and sharing information on the amount of paper used in the Library.

Professors are also becoming more cognizant of making materials online, for reducing cost to students and paper waste. Many professors opt to assign readings in PDF or online form or recommend electronic textbooks. And students are encouraged to look for electronic options as a cost-savings option https://www.northwestern.edu/financial-wellness/saving-in-college/buying-books.html.


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

During campus move-in additional cardboard recycling dumpsters are placed throughout residential areas. In addition to these dumpsters, cardboard "corrals" are erected in convenient areas during the heaviest move-in days. A "sustainNU crew" is deployed to remind new students about campus recycling and assist with recycling during the Freshman Move-In day. These crews both take cardboard to recycling locations and dumpster dive to retrieve any cardboard that might end up in the trash.

During campus move-out, collection boxes are placed in every residence hall and the campus recreational sports center for the collection of clothing, linens, small household items and nonperishable food. Nearly 10,000 pounds are collected for donation and reuse annually.
