Green Tea Cleans Hard Drive Heads 156
mprindle writes "Wired.com has an article announcing that a 'study of the use of green tea extracts for polishing the magnetic heads in hard-disk drives has yielded a compound that works three to four times faster than conventional compounds. If the findings can be reproduced in an industrial setting, the compound could reduce the cost and environmental impact of hard-drive manufacturing.' And you just thought that green tea was good to drink."

The conventional slurry has to be disposed also, according to strict environmental guidelines.
Furthermore, the green tea compound is just used to wash off the ceramic particles produced during polishing.
And I'm pretty sure that green tea biodegrades in any suitable environment, oxygen or no.

While it's true that bio-degradABLE doesn't mean that they're bio-degradED, it does open the door. Also, its probably more environmentally friendly to PRODUCE green tea than it is for other industrial chemicals, which may produce waste products that end up in the water supply, require high temperatures and therefore require lots of energy, etc.
So yeah, you're right that there is NEVER a magic-bullet. But if green tea is easier to produce, easier to refine, and can be broken down with a little simple composting, etc., then its a step in the right direction.

Until somebody spends another $1 million of our taxes (read: NSF grant) in doing the net impact calculation, consider this:
1. More land dedicated to grow green tea = less uncultivated land, less *nature*, as they say
2. Fertilizer & pesticide for green tea, and all of the petrochemicals that went into it
3. Fuels and other energies used to sow, harvest, clean, store & transport green tea
4. Chemical processes to refine bioactive compounds out of the tea itself
And I have not even mentioned the fuels used to create the wealth that is going to get taxed in order to pay for the agricultural subsidies that (of course!) are eventually going to be given to growers of green tea.

not to be pedantic, but this is not oxidation. As the original article states, the tannins bind to the tiny ceramic particles that that are unwanted on the surface. Thereby solubilizing them, allowing them to be rinsed free.

Unfortuneatly, green tea is only harvested 4 times per year in Japan. Green tea is very perishiable, and is best when fresh. The bags you can purchase in asian groceries here in the U.S. of A. have been sitting on shelves too long and taste like crap. (Bonus note: all the decaffeinated 'green' teas you can purchase in regular supermarkets will not taste like the real thing, pretty bitter and bland. There is no decaffeinating process that doesn't kill all the good things about green tea. Fresh green tea is naturally sweet and not bitter when prepared correctly.)
