Teen finds way to decompose plastic bags in just 3 months!

"If ordinary plastic bags would rot away like banana peels there’s no doubt a host of environmental problems would be solved, the fate of the turtle above included. And one 11th grader from Canada set out to make that dream come true as part of his school science project. A wildly successful endeavor he figures will make them decompose in just 3 months.

But how did this extraordinary young scientist named Daniel Burd pull it off?
Well, he decided the fact that they do, eventually, decompose after 1,000 years on their own meant there must be something out there causing it, and postulated that it might well be naturally occurring microorganisms behind it.

So he set about with the good old-fashioned scientific method as his guide, searching for the microorganisms, rarely found in nature, that actually do make plastic decompose.

Ultimately, he identified two strains of bacteria that work together to pull it off, with Sphingomonas serving as the primary decomposer with help from Pseudomonas.

And according to Burd, industrial application should be easy, "All you need is a fermenter . . . your growth medium, your microbes and your plastic bags."

As many folks know, the simplest solutions are usually the ones that work best. And this kid has clearly come up with a potentially world changing idea".

    • We need more research into this. We cant just start reusing plastics again out of the gazoo, and we need to find out if this truly works and how long it takes. We cant assume itll take a few seconds, these bacti are RARE, what if introducing tons of them will effect the environment? Plus we have to look at where the toxins go.

      However, this is a huge step forward, but we cant throw a party until its been proved as a safe way of getting rid of plastic. We cant just do it because its convenient, oil was convenient and look what that did.

    • If you could get all those plastic bags to your super duper compost pile, why couldn't you just recycle them from there instead of destroying them?

    • I'm not trying to be a downer but, what good is this information if the only (maybe the only) way to use this would be to place these micro-organisms on every plastic thing that we see lying around. It is helpful information, but not really...

    • The "Going Green" idea is not a problem to me. The problem to me is that people have all these Nazi rules about how to go about it without altering things to make "Going Green" an easier application.

      But Daniel Burd put his "Go Green" brain to use and figured out how to easy the problem of plastic taking so long to break down. That is what is needed. Not this general idea of "don't use that that's not environmentally friendly."

    • Awsome! Plastic is one of our worst materials because it doesn't decompose fast enough. If his method could be used widescale, it will be a big step in healing our invironment!

    • So great. Instead of enormously large piles of hazardous plastic goods polluting nature's waters and lands, we're going to have decomposed but equally poisonous masses of the stuff dotting the nation.

      Rats.

      But enough of my pessimism, and kudos to Daniel for the find. His solution is one more than we had before, and I see major develpements on his idea in the near future. Congrats buddy!

    • He may have found out how to decompose them, but is it economically viable? In other words, can we afford enough microorganisms to decompose all the plastic bags in the world? How about a single country? Are the microorganisms dangerous to other organisms? What about all the other plastic items? These are things we need to think about. It's great that we have found a solution, but is it a good one?

    • Sounds awesome! Kudos to you, kid! Let's just make sure that we know what we're doing with these microbes before we generate tons of them (Do these things make people sick/dead? We should find out in the least destructive way possible)

    • Great idea, but we have to be sure that we're not creating a bigger problem or simply shifting the problem. If we decompose the platic, are we just breaking the molecules down, making it easier for smaller animals to ingest or to simply absorb? We need more ideas like this, but we also need to make a shift as a society away from petroleum based plastics. There are annually renewable sources for plant based plastics now, one of the best being hemp. I would rather use Daniel Burd's invention on bio-platic, that way you know that the end result would be non-toxic. Also, if you've ever tried to compost the corn based plastic, such as forks and plates, you know that it takes a really long time, and Daniel's idea could speed up the process.

      Great idea this kid came up with. I'd have to agree with others, though, that more research is needed before we begin to apply it.

      It would be horrible to implement something like this on an industrial scale only to find out in 30 years that the broken down plastics get concentrated like mercury higher up in the food chain.

    • OK, now we just need to spray this stuff all over those giant spinning plastic-filled garbage pits in the middle of the pacific ocean. See http://current.com/search/search.do?indexName=en_us&renderer=jsp&q=garba...

      ...and no, plastic doesn't ever really "decompose" it "photodegrades" http://www.reusablebags.com/facts.php
      that is, it just breaks into ever smaller pieces; I picked up a shopping bag filled with... shopping bags the other day that had been sitting in my garage for over a year and they just... *POOF* broke into millions of tiny pieces, every time I tried to grab them, they just turned into dust.

      If these microbes do the trick, well, young man, you've saved the world! (or at least part of it)

    • Good old scientific method to the rescue! The answers are out there, we just need to keep looking and thinking innovatively like this young man! Complancency never saved any civilizations throughout history, don't know how we think it will now...

    • This is thinking in a way that's on the right track, but not quite there yet. When plastic eventually does decompose, it turns into toxic particles... still not great for the environment.

    • Smart kid, hopefully it actually gets used to help the world and not just swept under the rug like a lot of other stuff. As long as no big company has something to gain by plastic remaining not biodegradable then we should be good.

    • Great job kid. This is one step further in our hopes of leading a sustainable life. But this is no good reason for us to increase use of plastic.
      Can some of you kids also try nd patch up the Ozone layer?

    • That is indeed great news!

      Too many sea creatures-including birds, had died from mistakenly eating plastic objects similar looking to their own prey. Hopefully this will prevent it from happening.

    • What if these rare microorganisms are cultured and accidentally released into the environment? After 3 months every synthetic polymer will be decomposed thus rendering us helpless. Sweet.

    • There's another way for that similar stuff to decompose at that rate... it's called HEMP, and it has existed for thousands is not millions of years. I hate to say it but this kid solved our problems, yes, because we are too arrogant to use the SIMPLEST solution of all: grow hemp, everywhere!

      so yea, good for him, because we suck as a species...

    • I usually throw my bags in the ocean but I tie them to a rock so they sink to the bottom. Problem solved! That way the fish can live in them too.

    • I love hearing this, and congratulate the scientist. I do have a couple questions out of curiosity though. Are there ramifications of introducing microorganisms that are "rarely found in nature" into the massive waste management program that would be needed to deal with the number of plastic bags people use in America? Will the bags have to be shipped to central locations, thereby creating more transportation-related carbon emissions? I don't mean to be negative at all, and please pardon my ignorance as a non-scientist, I am just curious about shifting the balances of other factors in the equation. Regardless, this post makes me optimistic for change.

      A friendly reminder until something like this is a reality for consumers, please don't take a plastic bag when you can put your just-purchased goods in a reusable tote bag, a pocket or your own hand!

    • does this mean that plastic is good again....? i hope this does not turn into a reason to keep using petro-chemicals to make stuff. that ship needs to be put to rest once and for all.

      cheers to this kid tho!!

      innovate. share. enjoy. this kind of thing needs to be licensed under the creative commons or copy-left, so that everyone may have access. the future is coming. smile!!

      If I were ever a professional photosjournalist, I would hope that "getting the perfect picture" would not trump "helping someone in need when i have the chance"

    • now there just needs to be a way to convince the higher-ups in government that this idea actually works and that is can be a great step towards decreasing our environmental "footprint." Write your congressman!

    • Unbelievable! Awesome! Now let's go fish out all the plastic we've dumped in the pacific ocean and start composting it with these microorganisms.

    • great! Actually plastic does not decompose in 1,000 years, not even 10,000 years. I heard that plastic stay on forever on earth's surface. Please, someone correct me here! I am with no time for a scientific research right now. Thanks!

    • i've seen alot of potential world building ideas lately, implementing them is a problem. who remembers the british invention awards where there was a machine that produce clean water 4 out or 5 cups. how much do they need that in some parts of the world.
