For a while, there was very little upgrading of the capital stock, because everybody was trying to preserve cash. So at a time when prices were below the cost of production, you either shut down or you went through your savings. Either way, you weren't bringing in investment for upgrading.
In the last couple of years, there has been significant investment. Most of the investment has been by the billion-dollar green transformation fund, which people have used to upgrade and make all sorts of efficiencies, not just bioenergy. It has been a huge boon to the industry, but in addition to that we're beginning to see individual companies having their own private sources of capital. A lot of that right now has been going to delayed improvements that would have been done in the normal course of upgrading over time. Certainly in the pulp business we are seeing people going to dissolving pulp, looking at new applications, and going into more pulp and power.
We've seen modifications on the west coast in the lumber industry to allow them to process more pine-beetle-killed wood efficiently. So it's happening, but we'd love to see more of it happen.
