What does the number on the recycling symbol at the bottom of a plastic container indicate?

• A. Resin Type
• B. Brand Name
• C. Country of Origin
• D. Color of Plastic

Answer: (A)

That number identifies the plastic’s resin type. It’s part of the resin identification code used to sort plastics for recycling. Each number corresponds to a specific polymer, which helps recycling facilities know how to process the item and what streams it belongs to because different plastics have different melting points and properties. It’s not indicating the brand, the country of origin, or the color of the plastic. For example, common codes include 1 for PET and 2 for high-density polyethylene, guiding recyclers on how to handle the container.
