Why Zero-Waste?
We all generate waste every day, but we don鈥檛 always stop and think about how much waste we generate, where it goes when we are finished with it, and the broader impact it has.
Reducing the number of products we consume and dispose of is an essential part of social, environmental, and economic sustainability.
海角社区鈥檚 Zero-Waste Knowledge Base is a resource to help you understand the important impact of waste, learn what 海角社区 is doing to become zero-waste and rethink your consumption and waste sorting habits.听听
Environmental Impact of Waste听
Disposing of waste, through dumping in landfills or incineration, contributes to climate change, pollution, and environmental degradation. As materials decompose in landfill, large quantities of carbon dioxide and methane are released into the atmosphere, adding to global warming. 听
Methane is a powerful and potent greenhouse gas that has 86 times more global warming potential than carbon dioxide over a 20-year period.听According to听, 23 percent听of Canada鈥檚 methane emissions come from waste.听
What we throw away also has more immediate impacts on the health of our planet and people.听听
Landfills can lead to the contamination of soil and water through when rainwater leaches and draws out chemicals and contaminants when in contact with waste. This endangers ecosystems and the health of communities. Sending waste to landfill also creates additional air pollution, which lowers the quality of the air we breathe.听
Litter that is not properly disposed of is another large issue that contributes to environmental degradation. Plastic makes up to 90 percent of marine debris and trash which can cause suffocation, starvation, and drowning for marine life.听听
When plastics break down in the ocean, microplastics, which are plastics under 5 mm in size, are produced and make their way into water and food sources for humans and animals. Not much is known about microplastics and their impacts yet, but it is a growing concern. 听
Social Impact of Waste听
Waste disposal also has important social impacts that should not be ignored.听听
We know that landfills and incineration of waste can be detrimental to human health through the air, water, and soil pollution, but other negative impacts include noise, smell, and smoke.听听
There are also implications for waste disposal. near landfills are lowered because of these negative impacts.听 Moreover, landfills are more often located in neighbourhoods with a higher proportion of low-income and minority populations which is an example of environmental racism.听听
An 听is the large quantities of unidentified construction waste brought from large cities to Kanehsat脿:ke, amounting to the equivalent of 160 Olympic-sized swimming pools. This has resulted in being released near the community, threatening the health of people living nearby and local biodiversity.听 听

What is Zero-Waste?
The 听defines zero-waste as:
鈥淭he conservation of all resources by means of responsible production, consumption, reuse, and recovery of products, packaging, and materials without burning and with no discharges to land, water, or air that threaten the environment or human health.鈥澨
Zero-Waste Hierarchy
Zero-waste is not only about sorting your waste properly after using or consuming an item but also about what you buy and how it is produced.听听
The zero-waste hierarchy is a helpful tool for deciding the best course of action to achieve zero-waste.听
The hierarchy is:听
- Rethink听
- Reduce听
- Reuse听
- Recycle听
Circular Economy
Zero-waste is closely linked to the concept of a circular economy.听
According to UNCTAD, a circular economy is when:听听
- All forms of waste are returned to the economy, while residual waste is reduced to a minimum,听
- The constant extraction of new resources is avoided, and听
- The lifetime of products and materials is extended by reuse, repairing, sharing, and recycling.听
A circular economy is beneficial because it significantly reduces greenhouse gas emissions and environmental destruction through its reduction of raw material extraction. It can also boost economic growth and create jobs.听听
Zero-Waste at 海角社区
Zero-Waste by 2035
According to a 2018 waste audit conducted on campus, 海角社区鈥檚 landfill waste produces 540,000 kg of CO2 equivalent per year which is the equivalent of flying a Boeing 747 for 17.05 hours nonstop.
海角社区 aims to become zero-waste by 2035 by attaining a diversion rate of 90 percent, based on the 听
Reduce Your Waste
Using the Zero-Waste Hierarchy, here are some steps you can take on campus and beyond to reduce your waste.听
Rethink
Waste is a global challenge, but the sustainable choices we make creates a positive change. It鈥痠s up鈥痶o鈥痑ll鈥疢肠骋颈濒濒ians鈥痶o鈥痳ethink鈥痶heir鈥痗onsumption and鈥痑ddress鈥痶he鈥痺aste they鈥痯roduce.鈥
Learn more about zero-waste听听
Some ways you can learn more about rethinking your consumption on campus include:
- Attend the Waste: What Goes Where? online workshop offered to staff each semester by the 海角社区 Office of Sustainability and Organizational Development. This training will inform participants about how campus waste streams work, how to properly sort materials, and how this may differ from a remote working location.听听
- Attend the Zero-Waste Actions SKILLS21 online workshop offered to undergraduate students each semester by the 海角社区 Office of Sustainability. Participants will leave this one-hour training with best practices and a better understanding of 海角社区鈥檚 waste reduction strategy.听
- Apply to be a Zero-Waste Ambassador and build a culture of sustainability at 海角社区 by sharing knowledge about waste reduction and diversion, fostering zero-waste and circular economy practices, and encouraging our community to re-think its waste.听
- Become a Sustainable Workplace Ambassador and empower your coworkers to create meaningful and sustainable change, such as proper waste management, in their workplace.听
- Host a sustainably certified event by receiving consultations, training, and resources on best practices for sustainable event practices, including how to reduce material waste generated by events on campus.听
Reduce
Reduce the quantity of material and resources you consume and discard.听
Avoid single-use products听听
Eliminating single-use items is especially effective when eating on campus because food-related waste and packaging represent a large portion of waste on campus.听 Try making these zero-waste swaps:听听
- Bring a reusable mug for your coffee: As part of the鈥Lug-A-Mug鈥痯rogram,鈥痽ou'll get a discount on beverages when you bring your reusable drink container to鈥痯articipating locations on campus.听
- Bring a reusable water bottle: Thanks to the听Refill 海角社区听campaign,听海角社区 no longer sells bottled water on its campuses. Scope out the location of water fountains and taps near where you study or work.听
- Carry reusable dishware and cutlery.听听
- Carry reusable bags.听听
- Take advantage of reusable dishware programs on campus:听听
- Using the . Program helps avoid single-use packaging for your lunch on campus. Simply download the app and scan a QR code to borrow a container, bring it back, and earn rewards. Available at the Redpath Caf茅.听听
- 听is a service provided by SSMU that provides the SSMU cafeteria and events on campus with reusable dishware free of charge.听听
- Ask food servers at NRH, RVC, BMH, CS, and La Citadelle to place your food in a reusable Ozzi container. Return your empty container and exchange it for a token at the Ozzi machines for your next use.听
Buy less
Buy only what you need. 鈥婣void buying new things by sharing and swapping items.听 For example, instead of buying a packaged lunch, try bringing your own. You can warm it up using one of the microwaves on campus.听
海角社区 Little Free Libraries (LFL)鈥媋re designed for sharing books. Visitors are free to take a book and keep it, or return it when finished to any LFL on campus. LFL users can also provide a book of their own to an existing collection.听
Buy smarter/better听
When buying take-out or other items, try to avoid buying items wrapped in plastic or with excessive packaging. Prioritize items with minimal or easily recyclable packaging.听 One great option is the, which offers local vegetable baskets with minimal packaging every Summer and Fall.听
Reuse
Use products again, repair them, or repurpose them before replacing them. Give your old things a new life by donating them.听
On campus, this could take the form of:听
- Reusing notebooks if they have not been filled听
- Reusing plastic take-out containers and bags听听
- Buying refillable items, such as pens听听
- Repairing your items.听 provides an anti-oppressive space for all people to learn how to fix their bikes.听
- Buying used textbooks. See the 海角社区 Tribune鈥檚 听for some great tips.听
- Donating items you no longer have a use for. 海角社区 has鈥痑n initiative called the鈥Winter Coat Project, which allows students to recycle winter coats and support students who鈥痑re not鈥痯repared鈥痜or鈥疌anada鈥檚 cold winters.听
- Partnering with鈥to take your edible surplus food鈥痑nd deliver it to their food aid partners across Montreal if you are hosting an event on campus.听
- Contacting听,听a carbon neutral collection service,听during the spring move-out period to donate usable household articles such as furniture, clothes, books and electronics.听
Recycle
Finally, when your waste needs to be disposed of, recycle what you can so waste can be reprocessed into new materials or compost organic matter so that it can be decomposed and returned to the soil.听听
At 海角社区, everyday waste is divided into four streams:听
- Compost
- Landfill听
- Two recycling streams:
- Paper and cardboard听
- Plastic metal and glass
This is done to avoid contamination.
Learn more about what goes where at 海角社区 and to search how to sort over 1,000 items.听
Tips for Waste Sorting听听
- When in doubt, throw it out. Sorting materials in the wrong stream can lead to contamination of the compost and recycling streams, resulting in the whole bag being sent to the landfill.听听
- Separate packaging and products that are assembled with different materials. For example, separate lids from containers.听听
- Before sorting plastic into the yellow recycling stream, check for the triangle symbol on the item. If there is a #1,2,3,4,5 or 7 in the triangle, place the item in the yellow recycling stream. If there is a #6 in the triangle or no number at all, the plastic is not recyclable. Dispose of the item in the landfill stream.听听
- Food residue can contaminate other products in the recycling bin. Lightly rinse your plastic, glass, and metal containers and aluminum foil before disposing of them in the yellow recycling stream.听听
- Plastic and wax-lined paper are not recyclable or compostable. Place materials like wax-lined coffee cups and cardboard soup bowl lined with plastic in the landfill stream.听
- Only clean and dry paper and cardboard go in the blue recycling stream.听听
- Paper that has been soiled or become wet can be placed in the brown compost stream, as long as it has not been in contact with chemicals.
- Organic materials go in the brown compost stream. Anything that was once a living organism is considered an organic material, including food waste, paper products, and bamboo utensils.听听
