How would you like the idea of envoronmental friendly, totally degradable plastic, for use in packaging of food stuffs? Imagine what a boon it would be if we could throw away all those plastic packing materials that pile up in no time in our homes, into the earth, being fully assured that they would decompose soon to form valuable fertilizers...
Well, i happened to read through an article which mentioned how in the American state of Nebraska, they are making totally degradable plastic from Corn. It seems, dextrose is extracted from the starch in the corn kernels, and it is fermented and converted into polylactic acid (PLA). A sort of industrial resin is manufactured from this, which can be effectively substituted in the place of the regular plastics for use in packaging.
Another aspect is that while the manufacture of plastics consumes quite a lot of oil, this new procedure may turn out cheaper, considering the huge rise in oil prices and the rapid way this natural resourse is being exhausted!
It seems the world's largest retailer, Wal-Mart, has decided to sell some of it's products in PLA containers. Let me hope, that others too would catch up soon...
