Potatoes could be used for bioplastics

Posted June 08, 2007 4:52 PM

From MSNBC.com: Innovation:

The usual choices for potatoes include baked, mashed or french fried, but a new study suggests another option: plastic. A report by the University of Maine's Margaret Chase Smith Policy Center says the state's potato industry could benefit by becoming a producer of bioplastics, which are made from plant starch rather than crude oil and petroleum products. Bioplastics can be used to produce carpeting, upholstery fabric and recyclable plastic bottles, the report said. Countries including the United Kingdom and Japan have turned to potato-based plastics technology to turn out such items as "spudware," or plastic silverware made from potatoes.

...potatoes have been used to make people strangely pale and maleable for centuries.

I don't think we need new ways to make more kinds of plastic. We are putting far too much plastic (bottles and bags, and many other things) into dump sites. Why not teach us how to make fence posts out of our plastic? Or, if someone could come up with a small home version of a machine that makes little plastic pellets, where we could put our bottles, bags, wrappings, and many other things, and we could sell the pellets to someone who would make the fence posts. Think of the advantage of a plastic fence post. Light weight, termite proof, durable, and many other good things! Come on you inventors out there. Pull together a little machine that will make tiny pellets out of all the plastics that fill my garbage can! --David

VERY good idea david, I actually have been thinking about ways to compact my plastic bottles for easy selling to any recyclers.

I have a good sized wood splitter that is pretty strong, I'm sure I cound easily make a round compacting tube where the bottles would be compacted into tight tubes for easy transportation ..

This is a good concept...

but can we cut out the middle man?

If we can shred the plastic into longish thin strips (fibres) can we compress/weld/glue them into our 'plasti-wood' (TM pat pending etc ...joke).

With injection molding the heat & pressure is a problem, also the plastic needs to be clean and homogenous.

Shredding will consume some power unless we do it 'man-draulically'.

C'mon guys how do be bond the fibres into boards/posts etc?

Maybe old breakfast cereal & milk...that sets pretty hard?

HI ! Del-the-cat: !

THOSE fibre strips could be put in layers like ply wood is built with glued layers but in post shapes. With compression like in an extruder the posts can be formed. Now the trick is the design for the post to take so it won't come up out of the ground after a rain storm. they won't be good fence posts if they fall over after every heavy rain.

Fins and barbs!

And a real big gun to shoot 'em into the ground...

This could be fun!

Maybe we could just eat them! Specially if they sprout potaotes after the rain.

HI Del-the-cat ! again

The use of bioplastics is a oil saver and every way we can find to not use oil i am all for. the bioplastic is a well needed invention to get around the oil usage in this country. oil is to costly and in short supply, bioplastics is the way to go. I did see what one guy did with his plastic bottles & jugs, HE built a island in a lake in back of his house. by tying them together in squares and then tying the squares together into a 60 foot by a 80 foot island. wow what an idea! that's one way to recycle with out the government getting involved.

THANKS

HI david miller !

here in Connecticut we need a plastic that will break down in a gear or so after use.

this biodegradable plastic is necessary to stop the build up of millions of these bottles in our landfills and if a potato starch plastic would really fit the bill. the bottles will then break down at a specific date in there life cycle and disintegrate in the landfills giving us lots more space for other things. this is a most needed item in our polluted state.

thanks
