Once it leaves your hand and enters the container, you probably don’t give waste a second thought, but there’s a lot that goes on behind the scenes to ensure the university’s waste is being recycled or composted correctly. At home, a lot of what is accidentally thrown away can still be sorted out at the City of Edmonton Waste Management Centre, but it doesn’t work like that at the university.

“If people put things in the wrong bin, we have to reach into the bin and put it in the right one.” – Gerry, Students’ Union Facilities and Operations

“If you don’t know where something is supposed to go, it’s okay to ask us where to put items.” – Emma, Students’ Union Facilities and Operations

The University of Alberta is part of the Institutional, Commercial and Industrial sector, which means it is not part of the municipal waste system you have at home. Instead, the university must have its own waste contractors who collect and process waste and recycling. Someone who lives in a residence in Edmonton pays taxes which go toward municipal services like waste management. The university’s contract requires waste materials to be separated correctly, or it all goes to the landfill. This also means that the material in the university’s “landfill” stream does not get sorted further after it leaves campus – it goes straight to a landfill.

“Landfills are designed to not allow things to break down easily, or liquids to leach out. They are a highly anaerobic environment. Even a piece of food waste, which can compost quite easily, will sit there for years in a landfill.”

– Shannon Leblanc, Sustainability Coordinator, Energy Management & Sustainable Operations

Keeping as many compostable or recyclable items out of the landfill as possible is an institutional sustainability priority. For example, decomposing organics in landfills produce a gas which is composed primarily of methane, a greenhouse gas contributing to climate change. By keeping compostable items out of the landfill, the university can reduce its ecological footprint. With this in mind, the University of Alberta’s draft Sustainability Plan  has set a target to divert 90 per cent of waste from the landfill by 2020.

Getting to Zero Waste

To meet that target, the university is piloting Zero Waste stations in the Students’ Union Building, HUB Mall and Lister Centre. These stations move the university from a six-stream system to a simpler four-stream system which captures mixed paper, recyclables, organics and landfill waste.  Once these stations are working, the system will be expanded to the rest of North Campus.

To evaluate the new system, UAlberta’s Energy Management and Sustainable Operations and Buildings and Grounds Services perform regular waste audits to get concrete data about how well the Zero Waste stations are working. That means the waste is collected, labelled and sorted to see how many of the items are correctly disposed of, and see what items cause trouble.

Next time you need to toss an item, check out the containers to see where it belongs and help the university keep recyclables and compostable items out of the landfill.
