The blue-box castoffs are sorted by low-paid workers in huge factories, and recycled into inexpensive toys, shoes and colourful cardboard packages, before being sold back to Ontarians, where they fill the blue boxes once again.
Garbage experts say this revolving door is a necessary evil that will continue until the province has better recycling facilities so cities can process their own garbage.
"The question is, how much do we want to transport materials around?" said Glenda Gies, executive director of Waste Diversion Ontario, which oversees the provincial blue-box program. "We really do want to support the Ontario economy, we want to process these materials here."
Most residents recycle with the belief they are helping the environment and are unaware that their municipalities are shipping materials to China and South Korea, creating a huge new carbon footprint.
"It is a contentious issue here," said Jo-Anne St. Godard, executive director of the Recycling Council of Ontario. "We took advantage of (China's) cheaper labour force to have them clean, or re-clean, our recyclables, to sort out the more valuable items from the less valuable."
With the downturn in the recycling commodities market, China's demand for low-end mixed paper and plastic "residue" from blue boxes dropped considerably. But, Toronto, which sent up to 20,000 tonnes of mixed paper to China's massive Nine Dragons mill in both 2007 and last year, reports that in January, the mill began requesting more of the city's paper.
Toronto gets paid roughly $30 to $40 per tonne of mixed paper sent to China. According to Geoff Rathbone, general manager of Toronto's solid waste department, that worked out to be about $600,000 to $800,000 in 2007 and 2008.
In addition to shipping to China, Rathbone said the city sends about 10,000 tonnes a year of its "polycoat" milk and juice cartons to South Korea. If Toronto moves ahead with plans to recycle disposable coffee cups, it will send them to the same South Korean facility, as long as the owners can handle the influx, he said.
Still, Rathbone believes local paper mills and recycling facilities are the best option. "In the long term, I don't think (shipping to Asia) is a sustainable way to go," he said.
