Cascades Recovery, the company that processes the city’s recycling, believes we can do better.

"You can go onto the City of Ottawa recycling website and find out exactly what’s recoverable," said Dan Stone, the site’s general manager. "And whatever is not on that list, there’s no point in sending it here because it’s going to end up in the landfill." Plastic toys are not recyclable under Ottawa’s blue box program. (Jennifer Chevalier/CBC) The problem, according to people who understand the industry, is that most residents don’t bother to do that.

"There’s a huge confusion about what’s eligible to be recycled," said Duncan Bury of Waste Watch Ottawa.

The group is calling on the next council to triple spending on awareness campaigns — Ottawa currently spends about 50 cents per household, while other municipalities commit three times that —​ to make sure people understand what can be recycled, and what can’t.

Bury points to the city’s poor recycling rate as another reason to improve awareness. The more recyclable material that’s diverted from the garbage stream, the longer the Trail Road landfill site will last. At the current rate, it will be full by the mid-2040s.

"Leading municipalities are actually doing over 60 per cent, and the average is close to 50," Bury said.

"We’re the bottom of the big 10 municipalities in the province, and that’s a performance which we should not be proud of." Highrise, low rates

Toronto beat Ottawa’s recycling rate by seven percentage points in 2016, but those numbers may not tell the full story.

Ottawa is unique in Ontario in providing blue and black box recycling to all apartment buildings, where recycling rates are traditionally lower. That’s watering down the stats, according to the city’s director of solid waste services.

"Unfortunately, the diversion in those buildings is not the same as what it is in a single family home," said Marilyn Journeaux.

In single family homes, 50 per cent of waste is diverted from landfill, but in Ottawa’s apartment buildings the rate is just 17 per cent.

"We all have the ability to divert over 70 per cent of our waste," Journeaux said. "The challenge is how to move [residents] toward that target." Quality over quantity?

Ottawa does have one big plus in its favour. Our recyclables are relatively pure.

The contamination rate of Ottawa’s recycling is only three per cent — in Toronto it’s a whopping 25. That means a quarter of Toronto’s recycling has been tainted and is unable to be sold after it’s processed.

Ottawa provides residents with separate black and blue boxes, while other municipalities including Toronto and Gatineau have one large bin where all recyclables — glass, paper, tins and plastic — are dumped together. But when tiny shards of broken glass get mixed in with newspaper, that paper is ruined and likely headed to the landfill.Having a low contamination rate is critical, not just to keep waste out of the landfill, but also because it makes Ottawa’s recyclables more marketable. Different kinds of plastic, aluminum and steel are baled together, waiting to be shipped to end markets.
