Which plastics can currently be recycled in the US?

Polyethylene Terephthalate, commonly referred to as PET or PETE, is a type of plastic designated by the recycling code #1. It is widely accepted in recycling programs across many municipalities in the US due to its prevalent use in consumer products such as drink bottles and food containers. The recycling processes for PET are well-established, allowing it to be effectively recycled into new products.

In contrast, both Polyvinyl Chloride (#3) and Polystyrene (#6) are less commonly recycled. Many curbside recycling programs do not accept these materials due to the complexity and cost associated with their recycling processes. This indicates that while some recycling facilities may handle these types, it is not the norm across the country.

Thus, the choice of Polyethylene Terephthalate #1 as the correct answer highlights the current state of recycling in the US, where it stands out as the most commonly recycled plastic compared to others in the options provided.
