Sanyo Develops Corn-Based Biodegradeable CD

Recoil_42 writes "PC World has an intriguing article about one way to help ease a growing problem: computer waste. Sanyo, with the help of Dow, has created a biodegradeable disc made of corn. The discs take 50-100 years to degrade, well within acceptable limits, and should come to market by the end of this year. The speedbump, of course, is the projected price: 3 times that of a normal plastic disc, but that cost is expected to be reduced to 1.2 times as (if?) the discs become more popular."

    The average consumer is never going to buy a bio-degradable disc if its three times the price of a regular one. The only way to make them popular in the market is have the software and music companies use them and eventually it will trickle down to everybody.

      If they are three times the package price of a CD, noone will use them. But if they are merely three times the price of a blank CD, thats a different story. The actual physical medium is very cheap.

      That may be true but I wonder what the price difference is if they make the lactic acid directly from oil (like the plastic normal CD's are made of). That may be a bit less environmentally friendly but still better than non-degradable plastic.

      There are plenty of short term uses for CDs. Software might be one of them (I don't expect to be using anything on my shelf 20 years from now), although I wouldn't want to pay for a commercial software package, or music, on media specially formulated to degrade over time.

      Here's a good example - it's how I go through the majority of my discs. I use my digital camera, take about 70 or 80 pictures, download them to the PC. I remove the bad ones, leave the good ones alone, and fix the marginal ones (reframe, color correct, fix red eye, etc.). Then I burn the CD, take it to Sam's Club, and get great prints cheaper and of better quality then film (because I was able to eliminate or fix images).

      Then I throw the CD away.

      Sometimes I burn projects at work to take home, then I burn the work I did at home to bring it back to the office. I could use rewritable, but they cost more, and I don't use them that often.

      Rewritable CDs are also not as dependable, so I do backups on a regular CDR. Then, when I backup again, I throw the older ones away.

      Again, though, I don't think I want my backups on degradeable discs.

    Taken from Microfilm.com: "Under less-than-optimal storage conditions, digital tapes and disks, including CD-ROMs and optical drives, might deteriorate about as fast as newsprint - in 5 to 10 years. Tests by the National Media Lab, a St. Paul (Minn.)-based government and industry consortium, show that tapes might preserve data for a decade, depending on storage conditions. Disks -whether CD-ROMs used for games or the type used by some companies to store pension plans - may become unreadable in five years."
    How many times have you seen CD's left to reflect the sun onto the ceiling? Long after the data is lost due to lack of care, the plastic will still be hanging about. I think CDs that have a physical life span are a great idea for the environment. Companies which do look after their CDs can still get their longer lasting ones.

    Say what you want, but in 3000 years those CD's will be in much better shape then a book.

    The BBC project to preserve the doomsday book (onto laser disk) was rendered unreadable by advances in computer technology in less than 10 years, whilst the original has been around for ~1000 years and is still totally legible.

    The British Government still archives data onto vellum (goat skin) because it has a life span of >>1000 years, but CDs become unreadable in under 10 (maybe 20 for the very best well handled media).

    Now, if the data is only going to last for 10, whats the problem with making sure that the media breaks down in 50 instead of leaving it to uselessly fill up a landfil - plus these new ones wont leech industrial chemicals into the water supply, unlike the slower degredation of conventional CDs.

    Ah, but much of the items stored on current digital media is of a transient nature. Last month's reports, part of your mp3 collection, things that were important for the moment, but after then, are just another piece of trash. Yeah, important scientific works and the like are probably going to be stored on archival grade materials, but most people just don't need that sort of quality.

    Additionally, no current CD is going to last 3000 years. Period. Current CDs only last 50-100 years as it is before the substrate is corroded to the point that the disc is unreadable under even optimum conditions. So I'd much rather have the important ideas written down on paper than on a CD.

    You wouldn't want to do that, because, while food aids can make you feel all helpful and generous, they actually help to destroy local agriculture, by reducing demand and thus reducing revenue for farmers and the motivation to build up a farm in the first place.
    It would be more reasonable to give technological aid by helping with e.g., irrigation infrastructure. By doing this you could employ and educate local (third world) technicians and help build up a solid agricultural industry, which is the basis for any further advances like industrialization.
    On the downside the third world countries could lose their dependance on the first world, hence we give food aid.

    Got mod points, but I gotsta reply.

    In the Great State of Nebraska, we have taken 1.1 million acres of land out of production in the last 20 years or so. About 20% of our current corn production is being fermented into alcohol for use in E10 (Ethanol, 90% gas, 10% grain alcohol). Corn is still selling for less per bushel (currently around US$2/bu.) than it did 25 years ago (US$2.5/bu. give or take 2 bits) when I did field work for a seed corn dealer (a guy that raises the seed corn that other farmers buy to plant next year that becomes field corn that is made into corn flakes, alcohol, feed and hundreds of other things).

    Why? We grow more corn than there is any possible need for as food. Per acre production is up about 50% in those 25 years. Last season a farmer in Iowa got test plots over 340 bu./acre. Dryland. That's FUCKING INCREDIBLE!!! Roundup-ready and corn root worm resistant varieties, plus the ever increasing yields via hybridization will continue to increase these yields.

    Oh yeah, most of Nebraska is in a 4 year old drought, extreme conditions in the West and Southwest parts of the state. We will still have our second or third largest harvest of corn this year on record. Most of the corn is raised in less drought stressed areas, but it's been dry everywhere in this state for the last 2 years.

    As for fixing the starvation problem, that has absolutely nothing to do with the amount of food available world-wide. Those people are starving because of three primary reasons: no or not enough local production; no source of hard currency or trade material to acquire food on the open market (what, you want farmers to give it away? Or maybe us taxpayers should foot the bill?); and the most common reason, evil Marxist dictators running (can it even be called 'running'? ruining is more apropos) these "poor" countries. These dictators often are the cause of reason 2, since they steal all the countries assets to build themselves lavish Presidential Palaces, buy expensive European cars and jewelry, etc...

    Actually, we've got way too much corn. There was a great article in the NY Times magazine called "The (Agri)Cultural Contradictions Of Obesity" (Oct. 12 or 13, I think, but too old to link for free) which explains how:

    1) the price of corn directly affects the prices of many other food items;

    2) we produce way too much corn due to a screwy corn subsidy program which encourages farmers to produce as much as they can, rather than as much as we need, and this drives the price down to the point where we all get hurt;

    3) overproduction leads directly to increased consumption, and this is the reason that Americans are experiencing an epidemic of obesity.

    It's an astounding article -- head to the library and look it up, or just pay the Times a buck or two... it's very persuasive.
