I found this arbicle about the USB key made out of corn….. Enjoy..
This is latest drive from Hong Kong-based. Hoshino also takes a decidedly different approach than other drives that simply keep the hazardous chemicals and whatnot to a minimum, with it actually constructed out of polylactide (or PLA) made from corn that is, technically, biodegradable. The downside is that in order for it to be broken down, PLA needs to be blasted with heat for ten days on end at a specialized facility… well, not very ecological aproach…. -:(
