Non-Recyclables (Back to top)

One might wonder why there's an entire section dedicated to
non-recyclables on a recycling webpage - a valid question
from an uninformed observer. The truth is, understanding what can't be
recycled is in many ways MORE important than knowing what can be recycled - why?

When one aluminum can gets put in a garbage bin, it doesn't get recycled - this is sometimes an unavoidable event, when people are rushed, or appropriate receptacles are not available. But if a few errant coffee cups get mistaken tossed into a recycling bin, a whole day's collection is lost. It's called contamination, and while the majority of it comes from careless disposal, a significant portion results from misinformation.

Contamination is of great concern at McMaster University. In some cases, the offending pieces of garbage can be removed and the recyclables saved, but far too often there are too many contaminants to sort out. At one time, a staggering 90 percent of outdoor recycling bins were being contaminated beyond salvage every day - that means that a few careless or uninformed individuals were undoing all the recycling efforts of their comrades.

That's why we've dedicated a whole section to a list of items commonly mistaken for recyclables. But if you're ever confronted with a questionable recyclable, just THROW IT OUT... and take the time to follow up so that next time, you'll know what to do.

What should go into the waste receptacle?

  • Plastic lined coffee cups
  • Non-recyclable packaging (ex. Styrofoam)
  • Ceramics
  • Tissue
  • Aerosol cans (empty & non-hazardous)
  • Cloth items

Desk-side Recycling Bins (Back to top)

Unsure of what should go into your desk-side recycling bin?

Desk-side recycling bins are intended for paper products. Fine paper, cardboard, envelopes etc. can all be placed in your desk-side recycling bin.

On main campus, paper is taken from your office once every ten business days. Recycling and waste from the central recycling bins is removed daily.

If you have items such as food, pop cans, coffee cups or plastic bottles they should be brought to one of the central waste or recycling bins in your area.

Please note that custodians do not sort items from the garbage or recycling bins. It is up to the individual to properly place their own waste and recyclables into the correct container. If a bin is found to contain items other than paper products it is considered ‘contaminated’. Items from contaminated bins must be placed into the garbage to avoid further contamination of recycling from bins that have been properly sorted.
