IBox says "Production Machine is expected to process 15 Metric tons of plastic in less than 2 hours". A few posts say 20 tons per day. So what is going on during the other 22 hours? How long does it take to load/unload, clean, prepare and get ready for second batch? What I am asking is how long does it take from the start of one batch to the start of the second batch?
I can't imagine it takes more that a couple hours to load this thing and prepare for another batch. Even if it takes 4 hours, that's 120 metric tons per 24 hour day(15 tones in 6 hours).

IBox says "diesel is more pure than actual diesel" and the video says it can be run in an engine as is. So can the oil from the processor be put directly into offroad vehicles such as tractors and construction equipment? Why does this need to be sold to the refineries?
