Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

Due to a new international market, 5 of the 7 plastic types are no longer recyclable in the City of Flagstaff, thus leading to higher contamination rates with plastic that used to be accepted recycling in our City.

We utilize signage educated by behavior change research, bin uniformity and messaging consistency with the City of Flagstaff. We are working with the City's new recycling limitations to continually educate our student body. In Fall 2019, one of our Waste Min coordinators gave a presentation to the entire Residence Life staff and Resident Assistants to share updated recycling laws and provide residence halls with signage and programming. This presentation has led to additional educational efforts within individual residence halls and the creation of Thrift Jacks, a student club that works with dorms and Louie's Cupboard to donate or repurpose old clothing, shoes, and other school supplies by students, for students. Career Closet is another initiative that aims to provide donated professional attire for students to take at no cost.

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

O2G0: The O2GO reusable container program was implemented in collaboration with the Green Fund in the Spring of 2018. The goal of the program is to reduce single-use disposable waste in our retail dining locations. In our first semester, we had over 6,000 uses in just 5 dining locations. Due to this success, the program was expanded in the Fall of 2018 to 14 dining locations with the addition of reusable coffee cups. Since it’s implementation, NAU Campus Dining’s operation has become the largest university (by population) using the program. For more information on O2GO visit: https://in.nau.edu/dining/reuse/

Sustainable Catering: Our catering program has taken steps to minimize plastic disposables by making reusable dishware a standard in University Union events Instead of using plastic disposables at catered events, reusable dishware can be requested in events outside of the University Union for no additional charge. Catering also offers compostable service ware for no-frills events however, the customer is responsible for taking care of the waste. For boxed lunch events, catering offers sustainable box-lunches in reusable containers (all utensils and cups are also reusable with this option). Behind the scenes, catering has also replaced disposable gel burners with refillable burners! Eco-Burners, allow us to minimize waste and get the most usage out of our fuel tanks!

LeanPath: Leanpath is a back-of-house program that measures food waste by type and allows our chefs to see patterns of food that are wasted which can then be adjusted when planning the week’s menus.

Louie's Leftovers: Louie’s Leftovers is a program that reduces food waste and helps reduce food insecurity on campus by providing notifications through NAUgo letting students know when there is leftover food at catered campus events. The food must be eaten at the event but is available on a first come first serve basis to anyone who is hungry.

Thrift Jacks

Property Surplus:

Straw-Free NAU: In Fall 2018, we removed plastic straws from all dining locations and compostable straws are available upon request only reducing our use of straws by 87% (in the first semester). Campus Dining chose to eliminate plastic straws as they are small and often unnecessary plastic disposable that causes a great amount of harm to the environment. We also saw this as an opportunity to get consumers to think about if they really need some of the disposables they use, sometimes several times a day. Removing plastic straws from our operations has eliminated about 1 million plastic straws from our waste stream. We still provide compostable straws upon request to be mindful of our peers who may need a straw for medical reasons.

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

On February 13, 2020, the Office of Sustainability's Waste Min Specialist audited seven recycling dumpsters for contamination levels across various locations on campus. It covered student dorms, classrooms, administrative and public spaces. We are also tracking uniformity of City dumpsters which are being repainted to accurately reflect consistent coloring (blue for recycling and gray for landfill). We also conducted a waste audit and educational event at the Fall 2019 Homecoming football game. We found that recycling needs to be clearly messaged as only aluminum cans, plastic bottles, and cardboard/paper products. The use of mixed recycling seemed to confuse participants, which has informed our current messaging. Food collection and diversion could be considered for future tailgating events, though the amounts were minimal.

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

The NAU Purchasing department has established policies that address sustainable purchasing in the "Contracting and Purchasing Services Policy Manual." Among other items, when possible, practical and feasible, the University will strive to select products that are: Durable as opposed to single use or disposable, Non or minimally toxic, preferably biodegradable, contain a high recycled content, especially post consumer recycled content, highly recyclable at the end of the life-cycle, and shipped responsibly by combining shipments with other shipments to the University or region with
minimal packaging consistent with care of product made from recycled and/or recyclable materials.

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

Northern Arizona University is required by law to maximize use of all assets and, when it has no further use for them, maximize returns on their sale. We are not allowed to give surplus property away. The Property Surplus Department is the only NAU department authorized to dispose of surplus property. The primary role of the Property Surplus department is to ensure that the excess property generated by NAU will be handled in a method that both maximizes the return to the University and meets the disposal requirements of the state and federal governments.

Departments may use Property Surplus to obtain used materials such as computers, furniture, educational materials, and vehicles on campus and when materials are not used within the University, they are sold to the public at discounted rates.

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

Thrift Jacks club often hosts clothing and personal item exchanges based on student donations in the residence halls throughout the year. Career Closet aims to provide second-hand professional clothing to students from donations.

Louie's Cupboard is a location for students to donate food to our on campus food pantry to address food insecurity on campus.

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

In the library and computer labs on campus there either is no printing or charged printing. Free printing is limited to some Graduate Assistant Offices only. Facility Services has implemented three major changes to printing on most centralized printers; default duplex printing, default black and white instead of color printing, and enabled a secondary setting that reduced toner consumption by lowering the print density.

Facility Services was also awarded a Green Fund grant to purchase 12 tablets for building inspectors to reduce the need for printed plans. That translates to almost 600 plans a month that no longer need to be printed due to digital access with the tablets.

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

Course catalogs are available at: http://catalog.nau.edu/

Course schedules available through the student online LOUIE system.

Directory is found on the front page of the NAU website: http://nau.edu/

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

The "Donate Don't Ditch" campaign is the marketing effort to enhance the existing residence hall move-out waste diversion program benefiting local, not-for-profit agencies. Students can donate their unwanted goods during spring move-out that go to benefit non-profit partners. Donate Don't Ditch completed its tenth year in Spring 2019, and has partnerships with Big Brothers Big Sisters, Goodwill, and Sunshine Rescue Mission. Items that are collected include gently used clothing, furniture, small household items and electronics, books, cleaning supplies, and non-perishable food. Since the program’s inception, almost 390,672 pounds of items have been donated with over 47,680 pounds donated in the Spring of 2019 alone, our second highest yearly total.

The following is breakdown of the total weight of both materials and food collected for 2017-2019:
-2017: 50,080lbs total
Materials: 44,360lbs
Food: 5,720lbs

-2018: 46,242lbs total
Materials: 44,111
Food: 2,131lbs

-2019:47,680lbs total
Materials: 40,953lbs
Food: 6,727lbs

In 2018 and 2019, we worked with the City in a collaboration to address off campus student move-outs. The City partnered with Goodwill of Northern Arizona to successfully donate used items and divert items from the landfill from the surrounding neighborhoods comprised mainly of students.

During move-in, we provide additional roll offs for cardboard recycling. Temp staff is hired to ensure that cardboard is collected and that other materials are diverted to the other dumpsters.

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

Food waste is one of the biggest issues to solve, especially on a campus of over 30,000 students. For that reason, we are taking major steps to decrease food waste across all of our dining locations through a variety of initiatives.

Leanpath is a back-of-house program that measures food waste by type and allows our chefs to see patterns of food that are wasted which can then be adjusted when planning the week’s menus.

Food Recovery Network is an initiative that started in 2014, which utilizes student volunteers to pick up leftover food at dining locations and donate it to local Flagstaff food banks. This program is able to recover 4,000lbs of hot food every semester and donate it to those in need.

Compost machines are installed in both of our dining halls which collect both pre and post-consumer food waste. Everything from fruit trimmings, half-eaten pizza slices, and even the napkins and cups used in resident dining locations are composted diverting over 300,000 lbs of food waste each year and turned into the soil which is then used for the NAU campus.

Louie’s Leftovers is our newest program to minimize food waste at NAU catered events. The program allows for event hosts to notify students about leftover food after events through the NAUgo app creating an avenue for student’s with food insecurities to be notified about where to find food on campus.

At the University Union and Dubois center people can drop off batteries and printer cartridges to be recycled. Batteries can also be recycled at Facility Services as well as light bulbs. There is also a central drop-off location location for glass in parking lot P62B.

Additional documentation to support the submission:

For the Landfill and Recycling audits, the City of Flagstaff Solid Waste Department picked up all dumpsters for both streams. This daily amount was extrapolated to our average 3x times a week for average collection. This weekly average was then multiplied over 52 weeks to capture our annual total. We believe this estimation to be slightly inflated due to a majority of students being on campus 32 weeks, with decreased winter and summer classes and programming.

For composting, we launched an official pilot program in October 2019 with the City of Flagstaff to process their Green waste from City Parks and Recreation, and we are exploring processing additional waste streams such as pre and post consumer food waste and dog food from the Purina plant here in town.

Sodexo also purchased a new digestor for the two main dining locations to take all food waste diversion. Both of these changes have increased our composting totals substantially.
