If you listen carefuly that's what they stated they could do with the oil soaked hay. They could use it as a fuel.
What gets me is they always try to use complicated ways of doing things when sometime the simplest could work. What have they got to loose if it dosen't work? I think it would have some of those bigger companies pissed off like Mansanto or any other chemical company if such a simple solution would work.
