Yes there is an enormous difference in scale. Efficiency? In cell culture? In terms of GHG or emissions or energy use? I find that hard to believe. In my personal experience (not data, but relevant), none of the manufacturing scale processes were particularly optimized in terms of GHG/energy. Rather, yield was the primary target and consistency was the very close secondary target. Sometimes, vice versa. I 10x improvement of yield can very easily lead to higher GHG emission intensity, or no effect at all, e.g.
