Totally Green, for example, produces a corn-based water bottle that can be composted along with other food waste, and plans to use the label as soon as it is released, reports the Des Moines Register. Unfortunately, compostable chip bags never caught on thanks to their insanely loud crinkling, but these water bottles have no noise issues, so perhaps they'll have better luck.
Cotton and wool products won't apply because the program is intended to support the agricultural commodity market. That being corn, of course. Look for the label on anything from dish soap bottles to skin-care products. Will you make the switch?
