I can't speak to e-waste, but certainly what I can say is that you've made a very good point about research and development. There's been a lot of that, both private sector based and co-funded to support development.
I'm going to keep my steel hat on, if you don't mind. I made a reference to the development of lightweight steel. This is extremely important, again, to preserve the raw materials, the minerals and the critical components in steelmaking. It's this idea of making sure that we find ways to create the same properties that are required in an automobile, for example. There are certain properties that are required for safety and strength, of course, but this is to find new ways to chart new ground to get those same properties but with less material. That's a very real example of R and D doing what it can to support the development of ensuring that we're using as little of this stuff as possible.
