Question: what do the numbers on the recycling symbols mean?
Answer: The numbers and letters act as identification for the recycling teams. ... 1 = PET, Polyethylene Terephthalate, and is widely recycled. 2 = HDPE, High-Density Polyethylene, and is also widely recycled. 3 = PVC, Polyvinyl Chloride, and is capable of being recycled but harder to do so, so check with your local authority.
