Foam-Eating Worms May Offer Solution To Mounting Waste

ckwu writes: Polystyrene foams—including products like Styrofoam—are rarely recycled, and the materials biodegrade so slowly that they can sit in a landfill for hundreds of years. But a pair of new studies shows that mealworms will dine on polystyrene foam when they can't get a better meal, converting almost half of what they eat into carbon dioxide. In one study, the researchers fed mealworms polystyrene foam and found that the critters converted about 48% of the carbon they ate into carbon dioxide and excreted 49% in their feces. In the second study, the researchers showed that bacteria in the mealworms' guts were responsible for breaking down the polystyrene--suggesting that engineering bacteria might be a strategy for boosting the reported biodegradation.

    Good, because if there's one thing we need, it's more atmospheric CO2.

    Please spread polystyrene eating bacteria indiscriminately. Because it's not used as light structural support in anything at all.

    Polystyrene would keep that CO2 sequestered for what, 1000 years or so? And now they've just released more into the atmosphere with the cow farts and Volkswagen emissions!
