Question 15

Currently there is extensive recycling of which of the following polymers?

Accepted Answer

High-density polyethylene (HDPE) is currently the most extensively recycled polymer due to its durability, versatility, and widespread use in packaging and consumer goods. Polystyrene and poly(vinyl chloride) are also recycled, but to a lesser extent and with more limitations in terms of contamination and processing challenges.
