I can tell you that right now in Quebec, at EBI, two trucks are running on biodiesel. You can recoup methane from the dump site, and people do that. It has to go through a process of compression and then filtration, but they reuse it.
However, in my opinion you have to keep in mind that in 10 or 15 years from now, you won't be able to go to a dump site anymore. Why? Because if you go to Europe today and visit England, Germany, or Holland, you'll see that all the garbage from houses is segregated and all the organic and the other products are burned. They create electricity and steam with it and use it to heat houses and everything. I believe that the dump yards people see today are not going to be very evident in the future.
Maybe we’ll have to find a way to recycle some of the plastics. I don't know which types and I'm not a chemical analyst, but from what I've seen—we have a division which is a little into chemicals and biomass—they burn mostly everything. It's incredible.
