Zero-Waste Facilities

We operate two Certified Zero-Waste facilities on campus: the caf and the Food Court.

These locations are audited by a third-party organization who assesses if waste is being placed in the proper stream (i.e. organics, recycling, landfill). ‘Zero-Waste’ status indicates 90% or more of total waste is being diverted away from landfill.

How do we achieve zero-waste?

Waste Diversion Walls

We have made recycling easy by installing waste diversion walls across campus. The walls feature a physical piece of each type of packaging used in the dining location, with each piece of packaging hung above the proper waste stream. These visually engaging walls provide all the information a customer needs to correctly dispose of their waste, eliminating the guesswork often associated with recycling.

Packaging and Tray-Free Dining

Eating at the caf is a packaging-free experience. The dining hall also does not utilize trays, prompting customers to be more selective about the amount of food they serve themselves on one plate.

On average, the removal of trays reduces food waste by 25-30% per person.


All of the food waste coming out of our kitchens is sent to an organics facility for composting. The food is transformed into nutrient-rich material to be used by farmers as fertilizers.

Did you know?

Instead of composting, our Starbucks Page Break location gives away free coffee grinds during the summer to be used as a natural fertilizer for people’s gardens.


Glove Recycling

We recognize the importance of maintaining safety and hygiene, which is why gloves are essential in food services. Unfortunately, the current reality is that gloves cannot be recycled in Ottawa or many other recycling facilities, leading to a substantial volume of gloves ending up in landfills. Slow decomposition, worsened by temperature, UV light, and mechanical forces, turns gloves into microplastics that can harm our environment.

To address this issue, we partnered with EPI Canada to divert our gloves from landfill to an appropriate recycling facility. This recycling initiative holds immense importance because it transforms our used gloves into new recycled products. Through this initiative, we minimize our environmental impact and embrace a sustainable solution that benefits not only our community but also the planet.


Our kitchens are equipped with a food waste tracking program known as Leanpath, which utilizes a scale and camera to provide real-time information about the waste we are producing. Based on recent Leanpath data, our team identifies the largest opportunities for waste prevention and creates waste prevention goals for those specific food items.

Since the system’s implementation, the average amount of pre-consumer waste produced by our dining hall kitchen has decreased by 84%.


Surplus food is an inevitable feature of our operations.

What’s not inevitable?

That food’s final destination being a waste bin.

Nearly 60 percent of food produced in Canada – amounting to 35.5 million metric tonnes – is lost and wasted annually. Of that, 32 percent – equalling 11.2 million metric tonnes of lost food – is avoidable and is edible food that could be redirected to support people in our communities.

The Avoidable Crisis of Food Waste, Second Harvest Technical Report

Food Donation - Made Easy

Canada’s largest food rescue organization, Second Harvest, developed a platform that connects businesses with excess unsold food to local social service organizations who will put it to great use! Carleton Dining has utilized Second Harvest to establish recurring weekly donations for items such as all of our unsold to-go Express meals.

Addressing Food Insecurity

In the 2022-2023 academic year, Carleton Dining made an impact by partnering with Second Harvest to distribute surplus food, which would have otherwise gone to waste. Through this initiative, 1,326 meals were provided to individuals facing food insecurity in the Carleton community. This addresses a pressing issue and contributes to sustainability efforts by preventing 6,777 lbs. of greenhouse gas emissions and saving 570 kg of food from being discarded.


Coffee cups are the most common item in campus trash cans. Our Lug-a-Mug program helps wipe out waste by incentivizing the use of a personal reusable cup. Bring a reusable mug to any Dining Services location on campus and receive a $0.50 discount! If you buy a coffee every day
with a reusable mug at Carleton Dining Services locations, you’ll be receiving a FREE cup of coffee every other week from the Lug-a-Mug savings.
