I think the amount of fuel they may have already produced is insignificant. I don't mean they have only produced "an insignificant amount", but insignificant in the sense that .. other than perhaps generating a small wad of cash the instant they sell it and making all longs feel warm & fuzzy inside, it won't help the share price any.
The only thing that truly counts is the volume of fuel they can consistently product after receiving the permit, and for that they need a LARGE steady stream of cheap/free plastic (which all signs point to them having!).
But if I had to guess, with their testing and based on some statements they've made in the past, I'd guess maybe 2000 barrels (300 tons of plastic), or $150k worth?
I hope, upon receiving the permits, they will make some announcements about recurring/future quantities, as it could help to support the share price. I'd like to see a repeat of last December .. but this time based on much more than speculation.
