A brief description of the residual conversion facility:

Air filters collected by Dafco from Humber College go through an incineration program where waste is converted into energy. The service provider, Emerald Energy From Waste Inc., is located in Brampton, Ontario.

Emerald recovers thermal energy from solid non-hazardous waste from municipal (MSW) and industrial, commercial and institutional (IC&I) sources. The recovered thermal energy is converted to electricity and steam for use in communities.

The facility has 5 gasification units, each having a processing capacity of approximately 100 tonnes per day for a total processing capacity of 500 tonnes per day. Our facility has been in continuous operation since 1992, processing over 2.5 million tonnes of waste to date.

Start and end dates of the performance year and baseline year (or three-year periods):

A brief description of when and why the waste generation baseline was adopted:

Waste generation baseline was adopted in 2012 because 2012 was the first year we conducted a full waste audit at Humber College. Ever since then, we have conducted an annual waste audit every year.

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

Humber is constantly expanding its waste management program and has introduced holistic solutions to reduce waste production and encourage reuse, recycling and composting on campus – all of which have helped reduce waste sent to landfill.

At our campuses, Humber has introduced new centralized Four-stream Sorting Stations. These stations include compost in key areas and clear signage to make sorting waste as easy as possible for members of the Humber community. Previous bins have been donated and the new stations are made of recycled milk jugs.

Several recycling programs are available at Humber that aim to reduce landfill volume:
- Reusable Container Programs: Both North and Lakeshore campus have their own unique reusable container program (O2GO and Friendlier Programs) which students, staff and faculty are invited to participate in at the campus they are on
- PPE Recycling: During the course of the pandemic, masks, gloves and other single-use items were essential in staying safe. Both Terracyle and Green Circle Salons are services Humber has used to recycle PPE.
- Battery Recyling: Battery drums from Raw Materials Company Inc. have been placed across campus to collect used batteries in need of recycling.
- Pen Recycling: Pen recycling boxes from Terracycle have been placed around campus to collect pens and pen caps, mechanical pencils, markers and marker caps including dry-erase and permanent.

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?:

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

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

Average contamination rate for the institution’s recycling program:

A brief description of any recycling quality control mechanisms employed:

Training of all Food Service and cleaning staff on conducting visual checks of recycling and waste bags so they are appropriately disposed of on site.
Facility where our material goes to has capability to separate various materials.

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

Have designed signage on all bins throughout college, in office kitchens and cafeterias. Developed a campaign including TV ads and videos with recycling characters that help educate students, staff and faculty on how to recycle on campus. Run campus clean ups frequently throughout the year encouraging participation through 'which department can pitch in the most'.

The college has numerous programs (e.g. recycling, compost, battery recycling, pen recycling, campus cleanups, etc.) to support the campus community, but has received feedback that the system previously designed for the whole campus, did not accommodate some individual or departmental needs. As a result in 2018, Humber began designing a more accessible system by conducting discussions with individual faculties, shadowing staff, and surveying students. Using the information gathered, Humber ran a pilot of its waste strategy (new bins, signage, training, education) in one building on campus to gather feedback and further refine its approach. This process differs from traditional waste management plans as it embraces principles from Community Based Social Marketing and considers unique barriers and needs (psychological, physical, and systemic) facing a diverse 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:

Annual waste audit conducted in the fall. Audit outlines a full 24 hours of waste and recycling collected from key selected areas for a representative sample. Conducted at both campuses. This provides information on what contamination is found in the recycling stream, and directs efforts of what needs more education to campus users. All waste audits since 2012 are publicly available at humber.ca/sustainability

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

The college purchases paper through our mail room and then distributes to faculties and departments by request. This reduces the number of deliveries and packaging that would be required if each school and department ordered their own paper.

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

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

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

Students are given credits towards on-campus printing at the beginning of each semester. Once these run out, they must pay for printing. All library and computer lab computers are set to double sided printing by default. Staff and faculty are educated and encouraged to set their computer default to double sided printing and many areas have 'hold and release' function set up.

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

Humber directs current and prospective students to the college website for information. College directories are entirely on-line as is all registration information. Current students access grades and timetables through the web-based Student Registration Services, and all printing of these documents is done by individual request only. In the classroom, all course outlines, course schedules, and most assignments are posted on Blackboard, a virtual learning environment. The college prints a limited number of college catalogues.

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

Large cardboard totes are stationed in the residence common area for several recycling streams during move-out week: clothing, housewares (pots, pans, etc.), books, electronics, non-perishable food, etc. Signs, social media, email and communication through the Residence Assistants are directed at student residents during the 3-4 weeks leading up to move out week. At the end of move-out, the bins are picked up or delivered to appropriate organizations:
• Non-perishable food is donated to a local charity
• Clothing, housewares and books are donated to a local charity
• Electronic waste is sent to a certified e-waste recycling company

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

Students from the fashion program have organized an 'Eco Closet' event two years in a row. Students, staff and faculty donate clothing and the class runs an clothing sale. Money raised is given to a local charity and any leftover items are donated.

We are partnered with Terracycle to collect finished pens.
We have multiple battery recycle bins at each campus.

Additional documentation to support the submission:

The discrepancy between the performance and baseline year are due to the waste management programs that the Office of Sustainability has supported in recent years, along with the compounding effects of the COVID-19 pandemic. A significantly smaller amount of waste was produced on campus during the reporting time period, due to the stay-at-home orders, and this is reflected in the data.
