How Toronto sorts out blue box mess
I hate to throw out things like old sneakers, thereby sending them off to a Michigan dump. Other people have overcome that reluctance by tossing old shoes optimistically into blue bins.
Sneakers were among the recycling misdemeanours I noticed at the city's sorting facility in Downsview, just off Chesswood Dr., south of Finch. There were also soccer balls, frying pans,[url=http://woolrichoutletitalia.halod.com/][b]Woolrich Arctic Parka[/b][/url], auto parts, vinyl-coated wire racks, carpet, small propane canisters (yikes!) and hunks of concrete. On a conveyor carrying glass destined for reprocessing,[url=http://woolricharcticparkaherenoutlet.olimx.com/][b]Woolrich Arctic Parka Heren[/b][/url], fridge magnets and lighters were along for the ride.
While some municipalities refuse to pick up bins with recycling violations, Toronto appears more tolerant. John Baldry, the city's acting manager of processing operations,[url=http://duveticaonlineitaly.albirank.net/][b]http://duveticaonlineitaly.albirank.net/[/b][/url], who took me on the plant tour, explains why:
"If someone puts out 100 pounds a year, and 20 pounds is junk, there's still 80 pounds that we can recycle. What is residue today, we work out how we would handle it if we could use it."
Besides, having "unsolicited materials" representing only 15 per cent or 20 per cent of the total isn't bad. If you came away with that many errors on an exam, you'd have a pretty good grade.
The plant at the Dufferin Transfer Station processes 40 per cent of our blue bin trash. It's amazing that two shifts of 40 people, 35 of whom do the actual sorting, manage with the help of machines, to process so much garbage. The balance is handled by another privately contracted plant.
The recycling facility occupies about 55,000 square feet. It's gloomy,[url=http://duveticaaustraliaoutlet.halod.com/][b]duvetica down jackets sale online[/b][/url], except for sorting stations at various points along conveyor belts. It's also noisy - although some people could hear their radios - and dusty, with shredded paper draped on dirt-laden beams. Equipment has been fitted into the big open space on different levels, like some gigantic Meccano-set fantasy, with conveyors,[url=http://billigtmonclerdunjackastockholmrea.olimx.com/][b]Billigt Moncler Dunjacka Stockholm[/b][/url], motors,[url=http://woolricharcticparkaherenoutlet.olimx.com/][b]Woolrich Parka Sale Dames[/b][/url], chutes, turning disks and some high-tech devices.
Blue bin debris is dumped on the facility's tip floor at a rate of about 350 tonnes a day (as long as there's no garbage strike). At the other end, bales of recyclables - polystyrene, plastic tubs, pop bottles, aluminum, milk and juice boxes,[url=http://billigeparajumpersjackendamen.albirank.net/][b]parajumpers long bear[/b][/url], plastic bags - accumulate until there's enough for shipping. Newsprint goes right into a trailer to be trucked to one of two mills,[url=http://monclerjackenoutletch.albirank.net/][b]Moncler Weste Billig Moncler Jacken Outlet Moncler Outlet Österreich[/b][/url], both about two hours away. It could be back on your doorstep in a couple of days.
"It's an amazing thing,[url=http://billigeparajumpersjackendamen.albirank.net/][b]Parajumpers jacken damen[/b][/url]," says Baldry, who began his career in auto-parts manufacturing. "You start with a big mess, and you end up with a saleable product."
In 2008, before commodity prices plummeted, the city earned $24 million from recyclables and managed to divert 44 per cent of city waste,[url=http://duveticapiuminiitalia.webmium.com/][b]Duvetica Piumini Italia Outlet[/b][/url], including organics, from landfill.
The material comes up a conveyor at a fair clip to a first level, where five people try to pick out recycling faux pas and pull off bundles of plastic bags or shredded paper. The mixture then passes through screens, which are actually rotating disks,[url=http://duveticaonlineitaly.albirank.net/][b]duvetica jackets shop online[/b][/url], positioned vertically, with decreasing space between the wheels. The screens try to separate out cardboard, paper,[url=http://billigeparajumpersjackendamen.albirank.net/][b]Parajumpers jacken[/b][/url], containers and glass.
At various points,[url=http://billigeparajumpersjackendamen.albirank.net/][b]http://billigeparajumpersjackendamen.albirank.net/[/b][/url], the sorters - women excel because of good hand-eye co-ordination and patience - remove contaminants or pick out materials wanted for recycling, such as plastic food tubs and detergent and bleach bottles.
Equipment helps. Magnets extract cans. Optical sorters spot PET pop and water bottles, and when these items pass a point on the conveyor,[url=http://billigtmonclerdunjackastockholmrea.olimx.com/][b]Moncler Dunjacka Stockholm Rea[/b][/url], an air jet blows them into the appropriate stream. Milk and juice boxes are sorted in the same way. A rotating electromagnet with changing polarity causes aluminum cans to jump off the conveyor.
The plant is constantly battling marketing ingenuity and changing consumer habits. For example, large water jugs are now often discarded instead of reused. They can be recycled, but must be removed by hand before entering the sorting system, where they mix with cardboard or clog conveyors.
Or how about labels completely covering PET bottles that may catch the purchaser's eye but foil optical sorters?
"We put in automated equipment to maximize the capture rate and improve efficiency, and they put labels on that defeat the machine," Baldry laments.
Composite packaging, mixing different plastic resins or paper and plastics, may keep foods fresh, but contaminates recycling streams.
The future looks even scarier. Toronto's solid waste management team is planning a new sorting facility and invited packaging industry representatives to speculate what lies ahead.
Some examples make people like Baldry flinch: lattes in plastic containers,[url=http://parajumpersparka.webmium.com/][b]Parajumpers Jackets[/b][/url], which, with a twist of the bottom, mix chemicals to heat the drink; or smart wine containers that signal when to drink the contents and can restore wine that's gone off with chemical injections.相关的主题文章:
