flptrnkng: Very funny. Nobody said anything about having a contract for all the future sites that are a goal for expansion.
Further, I believe that the future sites include a global expansion, not just the U.S./Canada (is that number for all of N.A. or just the U.S.?).
I do believe that the earlier sites will find it easiest to acquire plastic waste streams. But the later sites will have the advantage of experience and further development of the process.
I would guess the trend for JV's to be co-location of processors at waste-management facilities where there is already an established waste stream.
