What Goes in Your Grey Bin? 5 Surprising Items You Can't Recycle in Guelph (2026)

Are you unknowingly contaminating your recycling bin? It's a common mistake, and it could be costing Guelph residents more than you think! While Guelph's recycling program has expanded, accepting more items than ever before in your blue bin, there are still some things that absolutely belong in your grey bin – destined for the landfill. Knowing the difference is crucial for efficient waste management and a healthier environment.

So, with the blue bin now accepting a wider range of plastics, wrappers, and even those tempting takeout coffee cups, what's actually left for the grey bin? According to a City of Guelph spokesperson, excluding organic waste and household hazardous waste (remember to dispose of those properly!), here are the five key categories:

  • Plastic Toys: That beloved action figure or doll might have reached the end of its playtime, but it's not recyclable. And a crucial reminder: always remove batteries before tossing any toy; batteries are hazardous waste and require special disposal.
  • "Flushable" and Disposable Wipes: Despite what the packaging might claim, these are a major culprit in clogging sewer systems and should always go in the trash. Think of it this way: just because it can go down the toilet, doesn't mean it should.
  • Ceramic Dishes and Glasses: Broken or unwanted, these kitchen staples can't be recycled with regular glass. Their composition is different, and they can contaminate the recycling stream.
  • Diapers and Hygiene Products: Unfortunately, these are not recyclable due to hygiene and contamination concerns. There's currently no practical way to sanitize and repurpose these materials.
  • Dryer Lint, Cotton Swabs, and Dental Floss: These seemingly small items can actually cause big problems in recycling facilities. Dryer lint is a fire hazard, and cotton swabs and dental floss can get tangled in machinery.

Beyond these five, unusable clothing, shoes, and other fabrics also belong in the grey bin. Circular Materials, the organization now overseeing recycling in Ontario, also specifies that pots, pans, and books are non-recyclable and should be disposed of in the grey bin.

But here's where it gets controversial... some might argue that with advancements in textile recycling, clothing should be donated or repurposed instead of going to landfill. What do you think? Should Guelph explore options for textile recycling programs?

Speaking of advancements, Circular Materials is investing heavily in new recycling technologies. "Circular Materials, alongside our partners and other stakeholders, have been working hard to drive investment in recycling technologies and innovations to support meeting recycling objectives on behalf of producers," a spokesperson explained. "This includes investments in local recycling facilities and other projects to discover innovative recycling technologies, and pilot projects on specific types of material to increase their recycling rates."

These innovative facilities are using advanced sorting technologies. Imagine conveyors and optical sorters working together, guided by technicians, to improve material quality. Optical sorters use sensors and cameras to identify and separate different materials with impressive accuracy. Material sorting machines then sort materials by shape, size, and density using oscillating paddles or plates. And this is the part most people miss: some facilities even use magnets to extract metals, while air jets separate lighter paper products!

Still unsure where a specific item goes? The City of Guelph offers a handy online tool called the "Wizard" to help you sort it out! Visit the City of Guelph's website (https://guelph.ca/living/environment/garbage-and-recycling/) and click the "Wizard" option below the green bar. It's a quick and easy way to ensure you're contributing to a more sustainable Guelph.

Now, it's your turn! Do you find the current recycling guidelines clear and easy to follow? Are there any items you consistently struggle with deciding where to put? Share your thoughts and questions in the comments below – let's work together to improve Guelph's recycling efforts!
