Nathan has started watching "Reading Rainbow" and while I should have been working out I started watching it with him. It was about making plastic from corn. Facinating.
The resin, known as polylactic acid (PLA), will be formed into containers and packaging for food and consumer goods. The trendy plastic has several things going for it. It’s made from a renewable resource, which means it has a big leg up—both politically and environmentally—on conventional plastic packaging, which uses an estimated 200,000 barrels of oil a day in the United States. Also, PLA is in principle compostable, meaning that it will break down under certain conditions into harmless natural compounds. That could take pressure off the nation’s mounting landfills, since plastics already take up 25 percent of dumps by volume. And corn-based plastics are starting to look cheap, now that oil prices are so high.
