I'll take the first stab at it.
I think a lot of us have looked at that opportunity, but I think there are a couple of things that are yet unknown. First, how much of this product will be available? And of course, that's fully dependent on what kind of segregation we're going to be able to achieve, what the regional differences are going to be, and where the location of those specified risk materials will be. That's the first thing.
Second, we're unaware of the chemical characteristics of some of this product until we understand what's in the mix. So that's the second thing.
And third, we're not exactly sure what the cost of it is.
So those are the other things. My other comment would be that if we extract it for biodiesel, or if we use it for biodigestion for thermal generation in electrical production, for example, that doesn't eliminate the problem; it doesn't get rid of all the byproduct. There's still considerable byproduct left. You're only taking the oil-fat portion out, remember, so you're still going to have this. Will we have degraded the prions appropriately enough so they can be disposed of in other manners?
There are a number of questions that need to be answered. We think it's certainly an honourable and appropriate thing to be researching and putting a lot of effort towards, but I'd argue today that these are unknown things. And to have private industry adopt it with all its unknowns is simply not going to occur. So that would be my answer.
