Have recently seen this claim circulating Facebook:
The image goes to a post by a group called UnbiasedAmerica... but it looks like the original source article is the story Starbucks Bans Plastic Straws, Winds Up Using More Plastic from the Reason Foundation, a group I hadn't heard of before.
The central claim appears to be measurements by the article's author that:
Right now, Starbucks patrons are topping most of their cold drinks with either 3.23 grams or 3.55 grams of plastic product, depending on whether they pair their lid with a small or large straw. The new nitro lids meanwhile weigh either 3.55 or 4.11 grams, depending again on lid size.
But I couldn't find any independent confirmation one way or the other. So is the claim true? (And if so are there any other important details that mitigate the claim, such as biodegradability??)
