There are a lot of different ways of answering your question. Material sorting is a challenge. A lot of the material sorting challenges have more to do with the colour of the plastic than they do with the functionality of it or with its durability.
We can definitely have improvements on that side too. Again, I am not fussy about where we start. We have to start in all the places at the same time. Where I'm fussy is when we might make very arbitrary limitations on what would constitute a recycling process or a recovery process. I think, if we're taking waste plastic out of the waste stream and putting it back into the economy, that's a check mark.
