So Lipton is now claiming on their tea boxes "no plastic film around the box" and "the teabags are plant-based, made from paper and cornstarch". Clearly trying to imply that the product is plastic-free, but not quite *saying* it.
So you might think, why is there cornstarch in the bags?
Well, from cornstarch you can make... PLA! A type of plastic. And indeed, the other side of the box talks about composting the bags, but specifically mentions "industrial compost" - because that's the only type of composting that can process PLA.
@Heidentweet I don't know the exact numbers, but it does need a temperature for some time that home composting doesn't reach, yeah.
