Stonyfield opted not to mark its new corn-based plastic
yogurt cups with the “7” recycling number, which is used as an “other” category
identifier for a host of plastics, including those made from plants. The brand
says that, because some #7 plastics contain substances like BPA or phthalates
that Stonyfield customers and consumer groups are eying as potential toxins, it
wanted to eliminate any confusion. Instead, the brand marked each cup (which,
it should be noted, can’t be widely recycled under the current recycling
infrastructure) with a “Made from Plants” message. The decision indicates an
understanding that material health and safety are key drivers for the brand’s
customers – do you know yours?
