This image displays the internationally recognized resin identification codes (RICs), where numbers 1 through 7 inside the Möbius loop indicate specific plastic types-from PET (1) to other mixed plastics (7). The eighth symbol is left blank to signify non-recyclable or undefined plastic categories, emphasizing the limits of current recycling infrastructure. These icons are critical for waste sorting facilities and consumer education on responsible disposal.
