No real idea, can't be older than last Spring, 2010, that was when the DEC allowed JBI to begin testing with the 20 ton processor and that is the 20 ton processor, working very well back then. According to the CC many changes have occurred since that video including how the plastic is fed to the processor. Lots of fine tuning occurred while they were waiting for approval from the DEC. Can't wait to see what they are.
