Default Blu-ray discs are environmentally safe!

http://en.wikipedia.org/wiki/Cornstarch
Cornstarch also has many uses in the manufacturing of environmentally-friendly products. For example, in 2004, the Japanese company Pioneer announced a biodegradable Blu-Ray disc made out of cornstarch.

The US don't care about the environment anyway.

And are they actually using this cornstarch disc or what? I can't find any news on that.

Um... doesn't biodegradable means it'll breakdown rapidly?

Why would I want my optical disc to be biodegradable? I want to keep my movies as long as possible.

Quote:
Biodegradable plastics made with plastarch material (PSM), and polylactide (PLA) will compost in an industrial compost facility. There are other plastic materials that claim biodegradability, but are more often (and possibly more accurately) described as 'degradable' or oxi-degradable; It is claimed that this process causes more rapid breakdown of the plastic materials into CO2 and H2O.

That's brilliant. Once you're done watching it, you can put it in the oven and you get a tortilla. Much better than those soggy boiled HD DVDs...

Maybe the organic dyes, adhesive, and anti scratch coating maybe biodegradeabel, but the that big round plastic disk is most certainly not.

1. It just says BD Discs *can* be made, not will be made (or even have been made) out of cornstarch. So this only applies to some future BD Discs.
2. I am quite certain that this also was already possible for DVDs, and most likely will also be possible for HD DVD.
3. Looking at the current trend of corn prices as they are used for bio fuel, I doubt it will be economically feasible for bigger production.
