Plastic resin identification codes and plastic recycling

Most plastic products have a recycling symbol with 1, 2, 3, 4, 5, 6 or 7 along with letters. This is the SPI resin identification coding system which is a set of symbols placed on plastics to identify the polymer type. The symbols used in the code consist of arrows that cycle clockwise to form a rounded triangle and enclosing a number, often with an acronym representing the plastic below the triangle. When the number is omitted, the symbol is known as the universal Recycling Symbol, indicating generic recyclable materials. See below for basic information or Click here to learn more about the 7 plastic identification codes.
