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.

Eric Lombardi, president of the Grassroots Recycling Network and a leader in the international Zero Waste movement, takes a nuanced view of PLA’s progress. He says it’s “visionary†even to think about biologically based plastic instead of a petroleum-based one. True, he says, there are problems with PLA, “but let’s not kill the good in pursuit of the perfect.†He suggests that the difficulty disposing of PLA reflects a larger deficiency in how we handle trash. He’s calling for a composting revolution. “We need a convenient, creative collection system with three bins: one for biodegradables, which we’ll compost, one for recycling, and one for whatever’s left.â€
Now we just need to shift back to hemp fiber instead of trees to make paper.
