I certainly take Mr. Burt's point from the manufacturing side that we don't have a problem with plastics; we have a problem with plastic waste. I hate to throw this spanner in the works, but is it possible that our conceptualization of single-use items might not be as useful a frame as durability? Some items that are not single-use are not durable at all, such as polystyrene used in a marine context. Other times, as some have pointed out, there are single-use items for medical purposes, where you start carving out an exception.
Make no mistake; I do want to ban all single-use plastics. However, I wonder whether conceptually we can frame this to make sure that our focus is to keep plastics out of the marine environment.
