Yes, because the residents are not necessarily good at cleaning everything the way you want them to. The other four plastics, typically the 3, 6 and 7, PVC, polystyrene and other plastics—that grand category of everything else—tend not to get recycled.
There is a lot of work being done, for example, in British Columbia. I was running the program out there. All of it was collected; we recycled all of it. The stuff that we couldn't recycle we turned into an alternative fuel that went to Lafarge, and we were actually cleaning the air in the Lower Mainland by substituting out the coal. So it isn't that something can't be done with it.
By the way, the PVC was pulled out. There was a system just to pull PVC out, so we were not burning it.
