Breaking down snack food bags proves problematic,[url=http://www.supra--shoes@#$%&/]supra footwear[/url]
A SunChips bag made of bio plastic is designed to break down in an active compost pile after 13 or 14 weeks. This bag was dug up after 13 weeks. ((CBC))
It sounds like a great idea: Make food containers out of a plastic that is derived from a food base and that will break down after they're tossed out, returning nutrients to the soil.
Bio plastics differ from regular plastics in that they don't contain petroleum products. They can be made from a number of sources,[url=http://www.p90x-workout.us@#$%&/]p 90 x[/url], including sugarcane, corn, soybeans and potatoes. If the containers are disposed of correctly,[url=http://www.nikeair-max.fr/]airmax[/url], they will decompose in weeks, unlike regular plastic,[url=http://www.beats-bydrdre-headphones@#$%&/]cheap beats[/url], which can stay in a landfill for thousands of years without breaking down.

Several "environmentally friendly" bio plastic products have been unveiled recently, including SunChips bags,[url=http://www.uggaustraliaonsale.us@#$%&/]uggs for kids[/url], gift cards and Paper Mate pens.
While they're described as better for the planet,[url=http://www.truereligion--outlet@#$%&/]www.truereligionbrandjeans@#$%&[/url], there can be problems if you don't dispose of them properly. The Paper Mate casing will break down,[url=http://www.ghd-hairstraighteners.co.uk/]ghd hair[/url], but you have to throw the rest of the pen in the garbage first.
The SunChips bag will only break down in an active, hot compost heap the kind that municipalities run. They're big enough to generate the high temperatures,[url=http://www.louboutin--pascher.fr/]louboutin chaussures[/url], around 50 C,[url=http://www.burberryoutletonline.in.net/]burberry factory outlet[/url], that the bags need to decompose. Backyard composters in northern climates may not do the trick.
Helmi Ansari,[url=http://www.prom-weddingdresses@#$%&/]vera wang wedding dresses[/url],the head of sustainability at PepsiCo subsidiary Frito Lay,[url=http://www.louisvuittonoutlet-online.us/]loui @#$%&[/url], says the main challenge in developing the first biodegradable snack food bagwas toproduce a strong,[url=http://www.karenmillen--dresses.co.uk/]karen millen outlet[/url], stable bagthat keeps chips fresh on store shelves but won't start breaking down if you leave it on the dashboard of your car with the sun beating down.
"Our vision is to leave no trace,[url=http://www.raybansunglassesoutleta@#$%&/]www.raybans@#$%&[/url], that's our sustainability vision. And when we thought about our food packaging, we thought,[url=http://www.ray--ban.it/]rayban[/url], 'Wouldn't it be great to have a food package that would leave no trace?' " Ansari told CBC News.
"We created this packageand tested it with the Biodegradable Products Institute,[url=http://www.gucci-outlet.us@#$%&/]gucci belt[/url]. ((CBC))
Butthe SunChips baglikely won't completely break down in your backyard composter, and most municipalities don't want the bags in theirorganic waste or recycling programs. The City of Toronto doesn't want bio plastics in its Green Bin program because there's a risk that it could degrade the quality of the compost produced. The city's garbage and recyclingunit stresses that composting facilities in Toronto and most other municipalities don't handle bioplastics well.
"Thechemistryof a bio basedplastic is completely different from an oil based plastic,[url=http://www.tiffany-andco@#$%&/]tiffany jewelry[/url],"Jo Anne St. Godard, executive director of the Recycling Council of Ontario,[url=http://www.@#$%&-rosherun.fr/]rush run[/url], said. "They behave completely differently in the recycling system. Godard adds that the system isn't there yet to separate the two types of plastic and that mixingthem can actually create more, rather than less,[url=http://www.louisvuittonpursesbag.net/]louis @#$%& speedy[/url], environmental harm. When bio plastics break down in landfill sites,[url=http://www.borse-louisvuitton.it/]@#$%& borse[/url], they emit methane that's released into the atmosphere.
Ansari says Frito Lay had two objectives when they developed the biodegradable bag:
Make a huge innovation from the non biodegradable,non renewable packagingthat doesn't break down.
Provide an alternative type of packaging to spurthe industry,[url=http://www.canadagooseoutletsale@#$%&/]@#$%& parka[/url].
"This is the first compostable bag in the world. We're developing the next compostable bag and we'll build the next one. So we're pretty excited about the fact that we have an innovation,[url=http://www.katespadeoutleta@#$%&/]kate spade sunglasses[/url],we have something that is a huge leap forward from previous packages,[url=http://www.@#$%&-free-running@#$%&/]@#$%& free run 5.0[/url], and it's probably going to excite so many other producers."
St. Godard says part of the problem for the consumer is confusion over packaging,[url=http://www.michael-kors-outlet-online.us@#$%&/]factory outlet michael kors handbags[/url]. How can you tella bio plastic snack food bagfrom one that's not?
In the case of the SunChips bag,[url=http://www.oakleysunglasses-outletcheap@#$%&/]oakley m frame[/url], it's not too difficult. It's apparent when you pick it up. It's a lot noisier than regular snack food bags. So noisy that Frito Lay bowed to customer complaints in the United States and took the bags off the market,[url=http://www.canadagooseoutlet-jackets@#$%&/]canadian goose[/url], pending some tweaks to make them a little quieter.
