A Paper Alloy To Replace Plastic Cases 182

xwwt writes "In response to a paper by Greenpeace's Guide to Greener Electronics, PEGA Design & Engineering has developed a new product that is intended to replace plastic shell material in computer equipment and electronics. The product contains a combination of paper and polypropylene (PP) which aids in recycling efforts and is intended to keep non-recyclable materials out of landfills. The PP should break down in sunlight and can be reclaimed. There is concern that polypropylene cannot be separated from the paper fiber and brings into question how the material will be recycled. As poster Paul Davis points out, it might have been better to use polylactic acid. Ultimately, it raises the question: is this truly a recyclable material?"

    Keep out of direct sunlight, product may disintegrate

    A long time ago, during a more optimistic time when we dreamt of jet packs and lunar colonies (no,not by sacrifing the rest of the economy Newt Gingrich style) recycling wasn't going to be a problem.

    Just drop waste into a plasma torch; everything would be reduced to "indivisible" atoms (yes I know that's what the word atom means).

    I guess that particular dream vanished with the electric power from nuclear reactors that would be "too cheap to meter".

    Anyway, not complaining too much. The past didn't see our future filled with fun handheld gadgets and the Internet. And who knows, maybe Siri will have a baby with Watson. (We should name him HAL). We also don't have nukes in low earth orbit ready to finish off the human race in a few minutes. Still, even though renewables will probably keep us warm in the winter and cool in the hotter summers, it's not clear that we'll have really high intensity power sources to squander, I mean use, anytime soon. I mean nuclear fusion is 20 years away and power from satellites even further.

    Let's just hope it doesn't get as bad as in "The Windup Girl".

    Will this laptop have a sunlight readable screen?

    The PP should break down in sunlight and can be reclaimed.

    Well, it did for a while.

    And it won't have any sunlight in the landfill so it won't degrade very well? I thought one problem with landfills is that things that should degrade do not due to a lack of sunlight, oxygen, etc. IIRC some researchers have dug around in landfills from the 40s and 50s and found well preserved newspapers and other theoretical degradables. On the other hand some landfills are producing enough methane to make capture economical. Is it a soil thing? Breathable/permeable vs something more impenetrable?

Make it myself? But I'm a physical organic chemist!
