The "♴" emote or the Recycling Symbol for Type-2 Plastics is a symbol used to indicate that a plastic item is made of high-density polyethylene (HDPE) and can be recycled. It was created in 1988 by the Society of the Plastics Industry to help consumers identify which plastics are recyclable. The symbol consists of three arrows forming a triangle, with the number "2" inside, indicating the plastic type.
