It fluctuates. It's a supply and demand situation. The world in general is protein short. The reason for that, of course, is largely aquaculture. Aquaculture in Asia and so on is growing. If you look at the graph of growth, it's almost vertical. There is a huge demand for protein meals for feeding farmed fish and shrimp and so on. Yes, the rendering industry does supply the domestic market for animal feed, and there is sufficient supply.
Ruminant meal, of course, with the situation with BSE, has become an issue, especially SRM. We produce 240,000 tonnes a year of SR material alone. When you render that you will get tallow—which is saleable—60,000 tonnes; you'll get steam, the moisture; and you'll get the protein, 60,000 tonnes, which has to be landfilled, because you cannot sell it, you cannot feed it. You have to dispose of it. It's waste material, so that becomes a cost-negative effect. That would be worth, if saleable, $400 a tonne. Instead, it costs $20 a tonne to dispose of, so now it's a negative $420 a tonne, on 60,000 tonnes of material.
Ruminant meat and bone meal are problems because we have an oversupply, so we like to export that.
