If I might just add, when we talk about energy from waste, not all of it involves incineration. Anaerobic digestion, for example, which my firm also does, is a good example of that. That being said, while in our experience incineration is a fairly expensive solution, it still has a place in dealing with the residual products that are produced through composting. For example, there are plastic bags—I heard Larry talk a little bit about that—with a cement kiln. We've actually run tests with several cement facilities as well and the material being used or burned is actually a cleaner source of energy than others.
The other thing is that we also use what we call 20-plus material out of our Ottawa plant to help fire kilns.
