Corn-based plastics are nothing new (your takeout food box may be made out of them), but their use in consumer electronics is. Fujitsu recently took the bold step of using corn-based polymers, at least in part, in one laptop, the FMV-BIBLO NX95X/D. (Now that's a name!)
Available now, but only in Japan, the BIBLO uses 50 percent corn polymer in its case and 50 percent traditional petroleum plastic. Why not all corn? Corn-based plastics aren't rigid enough for laptop use, and a bigger problem, they aren't nearly as flame-retardant. Considering laptop batteries' propensity to burst into flames these days, I'd say that's a big issue.
I checked out the BIBLO in person, and if no one had told me it included corn-based plastics, I'd never have known the difference. The case feels just like any plastic laptop case, with none of the greasiness or odd sheen that some corn plastics exhibit. But the corn-based plastic components of the case break down in a matter of months, ultimately halving the amount of physical waste a trashed case would create. Pricing is virtually the same as that of traditional laptops.
Fujitsu wants to bring the technology here, but certification takes time, and that flame-retardance issue is a big deal for UL and ISO, which need to sign off on the machine before it arrives in the States.
Join in the discussion. Here you'll see the comments in the order they were posted.
It will not degrade in 6 months when you use it, its suppose degrade in 6 months of landfill conditions. That’s still an "if" to some degree. The other problem is that there is a great deal of "computer plastic" recycling going on now with oil-based polymers. The corn-based polymers will not recycle with the oil-based polymers. So now we have an established waste stream (oil based computer plastics) contaminated with corn based polymers. They do not mix. It sounds good, and makes a great PR for the items Mfg, but it probably has much more of a negative impact for plastics recycling. If you want to do something about your used computers, make sure to use traditional methods to recycle them! Check it out on the web. It’s a much better idea than this! Let alone the ethanol craze driving up the price of corn, we all pay more for almost all our food products, from cereal to beef. Some studies I have seen say ethanol production pollutes more than oil?
Plastics made of corn might be interesting if there was enough food in the world! This will make corn even more expensive every day with the non'food approach of its use. Much helpful would be to use recycled plastics and to encourage to use more recyclable materials to produce new consumer goods. Also a share of the production of computers (whether made of plastic or corn should be devolted to poor countries that cannot afford to buy computers.
Yummy! Is it available with a butter and salt hard drive?
jen said it first... ethanol is a joke! http://healthandenergy.com/ethanol.htm Even if the above study is entirely false, the fact is ethanol still produces greenhouses gases and will destroy the environment! QUIT HYPING CORN, PEOPLE! Now THIS is a revolutionary green technology. This will change the world, if true. Yahoo! just discovered this today: http://news-service.stanford.edu/news/2008/january9/nanowire-010908.html
Or you get water on it and a corn field grows on your desk. LOL
I think what the author of the article needs to do is clarify "breaking down" in this case. FYI, here is Merriam-Webster's def of "biodegradable": capable of being broken down especially into innocuous products by the action of living things (as microorganisms)(www.m-w.com) Things can biodegrade above ground just as easily as below it. Place paper too close to steam for too long (such as in a kitchen or bathroom) and you'll see what I mean. Organic components also break down quickly in the sun or heat as well. Having organic parts can have implications for people living in the humid parts around the Equator (or just Southern US), for instance. I would assume the technology involved would prevent this, but I would prefer the author (or someone knowledgable at the company) speak to this.
Just throw some butter, salt, and pepper on it and you'll have yourself a really nice snack.
sleepeeg3 you hit the nail (http://news-service.stanford.edu/news/2008/january9/nanowire-010908.html). Imagine a battery that could power a car for 2000 miles instead of 200. Imagine a battery that could be successfully integrated into the home to power everything in it...replenished through solar energy. The entire thread has kind of gone off topic, but who cares. We (the human race) WILL get away from our dependence on fossil fuels. The question is, will they run out before we do. This is a huge step in the right direction.
hola
redrocker....dont be mean...come up with a solution yourself..then do something about it! I think that this might be a good idea..but i wonder how much energy/land is put into making this corn based computer in the first place. Listen people, if you have a laptop and you want to get rid of it...just make sure you recycle it...we dont really NEED a corn based computer, we just dont need the bad toxins from old laptops seeking through the ground in landfills. All of the corn jokes make me smile by the way...redrocker you are just a downer. : )
why not use asbestos as a the flame retardent?
Everyones saying corn is a bad source of alternative energy, and they're right. Hemp should be legalized and grown industrially. Hemp fiber can be used for paper, clothing, rope, and other fabrics. I'm sure with enough research it can be used as a fuel and type of plastic.
The author needs to read "The Omnivore's Dilemma" for an education on the petroleum consumption associated with present day corn production methods as well as the processing required to break the corn down into its basic constituents before producing the polymers he touts. To produce the yield-per-acre necessary to be profitable (even with substantial taxpayer subsidies) they use alot of petroleum to run the equipment, and to make the nitrogen-based fertilizers they require.
I have been reading everyone's posts and I am of the opinion that some of you did quite get the point of the story. If the cases were made of 50% corn polymers it would mean that when the case was no longer used and in a landfill, it (the case) would break down much faster than traditional plastics and thus not take up as much space in a landfill. It DOES NOT mean it would break down faster as a computer. That's the distinction one has to make when reading the artical.
If a person is going to objectively look at the use of corn or any other biofuel source, you have to set some parameters to the comparison. Corn based ethanol consumes petroleum products to produce, and if you compare inputs to outputs, the overall ratio is about 1.3 to 1. This means for every unit of energy put into producing ethanol, there is an output of 1.3 units of energy. The studies that say more energy is consumed to produce ethanol than the energy output fail to account for the energy consumed to process petroleum into a usable product. Corn based ethanol is not the long term answer, but a step in the right direction. Be wary of the talks of the use of biomass for ethanol production since one of the suggested sources is corn stover. Corn stover is the stalk and leaves left in the field after harvest, which acts as a fertilizer source. By using this supposed waste, the farmer will have to apply more fertilizer to replace the nutrients lost by consuming the corn stover. Guess what, most fertilizer is either made of petroleum products or requires their use for processing. On a similar note, think about electric car pollution. The car doesn’t pollute, but where does it get its energy from? Your electrical outlet, which most likely gets its electric from a coal fired power plant. The pollution is still happening folks.
Did not anyone watch Penn and Tellers Bull----, they clearly said that a twoby 4 mile ditch in a remote area would be ample for all the trash in AMERICA for 200 years. And that all recycling uses more energy to transport recyclables to these facilities , stop listening to crackpots , do the research.The only viable recycling resource is Aluminum. All the others use more fuel and cause more carbon and maybe formaldahyde. WAKE UP EVERYBODY DO RESEARCH, and find out the truth, These strange weather phemomenons have been documented by Preists from other countries for at least 600 years,what does this say for global warming.Do YOUR RESEARCH!! Then and only then will we know the truth!!!!!!!!!!!!!!

..oh yeah, also...we've been eating corn made of DIRT!!!!
