Recyclable plastic usually comes with a little recycling symbol printed on the bottom and depending on the product, there might be a 1, 2, 3, 4, 5, 6, or 7 stamped in the center of the symbol. It’s easy to miss, but this tiny digit is actually pretty important, because it’s an ID.
The number is a resin identification code, used to help recycling plants sort materials. Recyclable plastics are labeled with numbers 1-7 to tell workers what kind of plastic it is, and how it should be processed.
