Yes. For instance, if you have a plastic that's multi-layered, it's much more difficult to recycle than you might find with one of your clear plastic bottles where the label isn't affixed to it. That can be much easier to recycle, and it would be easier to reuse the plastic.
The idea of what you're using for your packaging and how it's made becomes important. There are conversations with respect to that, but also, I would say, information is needed in order to gain a better understanding of those important dimensions around the development of packaging, what it's used for and then how you can go about creating an alternate that still serves the same purpose. Those are important questions that need to be addressed as people think about how they put in place a requirement or work with industry for it to voluntarily look at that.
There are good initiatives going on with industry around that, where they are actually looking at their packaging requirements. They are thinking about it themselves and putting in place their own targets on how to reduce it.
You asked about industries being responsible for their own packaging. There are extended producer responsibility programs whereby they're actually involved in the funding and management of the programs, so that industry works to fund and put in place a program that allows the management of their product at the end.
Those are things that are also being looked at in terms of how to enhance that. When we think about extended producer responsibility, it wasn't developed with a single focus around plastics, so how does the plastic lens get taken into account? How can we go further with respect to that? A number of retailers are doing some voluntary measures with respect to that. There are things like Loblaws and Sobeys collecting their plastic bags for recycling—
