Biodegradable USB Key Made of Corn

The hunt for a new USB key is still on for me, so I’ve been keeping a look out for green possibilities. There is a new very interesting option. Hoshino has released a “world’s first” with their new USB key made from corn.

Corn is fermented down into polylactide (PLA) that can be biodegraded safely...but that does have to be done at a specialized facility with heat, which is not so earth friendly. You can’t just toss it in the trash and think no harm done, like we assume is true when things are labeled “biodegradable.” Also, we have to point out that when practically everything is starting to have corn in it, do we really want to base something on it? Perhaps using recycled plastic would be a greener way to go.

And finally, just in case you wonder about the source of the material, the USB is made to look like an ear of corn. Super dorkey. Oh, and it’s not available to the public yet… So my half-hearted hunt is still on for now.

I wonder how much memory our mind can ho
written by Jason, August 11, 2008

I wonder if there ever will be any 'organic' forms of memory storage in our lifetime? Something akin to plugging in 'a brain' into an USB port... assuming those brains are biodegradable and require less energy/carbon emissions to produce than its equivalent plastic/metal counterpart - that is. ;D

Biodegradable - so what?
written by Kit Strange, August 12, 2008

Bioplastics are all well and good in some circs - eg closed loop applications. But if they get landfilled what is the benefit of having something degrade anaerobically creating methane, a potent GHG.Better then to have non-bio surely? What happens if bioplastics contaminated fossil-based polymer recycling chains? You get a sub-standard recyclate with lower value and less applications. I think we need to be careful finding just the right purposes for bio-polymers. Catering equipment for festivals would be one.

Why not wood?

Wood is biodegradable too: http://www.hmdiffusion.com/aoC...amille=498 ;D

PLA isn't "biodegradable"
written by Mike, August 12, 2008

PLA isn't really "biodegradable", that would imply that it requires some sort of living creatures (e.g. bacteria)to break down. In fact PLA is a hydrolytic polymer, meaning that it is broken down by water. Heat and acid increase the speed of the reaction, but aren't necessary. The reaction produces lactic acid, a fairly benign chemical. PLA is commonly used in biomedical implants.

PLA
written by Ali Syme, August 12, 2008

PLA is the number 1 commercially manufactured bioplastic. The products will compost and biodegrade depending on the concentration of PLA in the product - which can often be 50%. It of course needs oxygen to compost - which might not be the case in landfill.
