ALLM process most cost efficient, according to "whom"?

ALLM would lead you to believe that their process would be a vast improvement to the current method of cellulosic conversion processing;

http://www.altenergymag.com/article/2017/04/cellulose-to-sugar-cts-technology-for-ethanol-production/25950

This article states that the dry-mill corn ethanol process is energy inefficient from a mass balance perspective. However, this viewpoint could be farther from the truth based on the corn ethanol production flow diagram I supplied in earlier post. Every "waste stream" such as CO2 (captured and used to make dry ice), corn fibers (recycled back in ethanol process), etc., is currently being repurposed, sold as a by-product, or re-used to increase efficiency in ethanol production. I would be willing to bet there have been vast improvements on costs for this process. Otherwise, why keep them open?

I would like to highlight that the ALLM production costs given so far are "projected" based on modeling because they have no real data to support their production cost claims for their technology. You can't until you have an actual plant scale process running in continuous operation that incurs these real operational costs. Let's see if the are still at $0.05/pound if they succeed with the purchase of the Florida plant and get it running. Production costs from lab scale demonstration mean nothing in the real world of commercial or industrial chemical production.

I will share with you who has and is light years ahead of ALLM;

Note how Greenfield has slowly ramped up from concept to R&D, to pilot plant and then commercial scale ( and this was 2 years ago!). They even have a mobile truck bed skid that can come to your door and be demonstrated. Everything ALLM has stated thus far is a projection or concept; nothing more. Read very carefully the wording being used to describe their process and what they make. The end product is C5-C6 sugars and lignin. In the past 2-3 years, they should have had corn ethanol and sugar ethanol companies lining out the door testing their process to improve their own or specialty chemical companies testing their lignin product to replace their current feedstock, but you hear nothing of it. Better yet, the USDOE-BETO program could have helped them via the US government led R & D program for biofuels and bioenergy.

I am sorry, but if this is such a "global disruptive technology", then why hasn't the USDOE recognized ALLM or their mechanochemical process? Where are the big chemical companies?

Did you notice how eerily similar Greenfield describes their process in 2014 and then recall how ALLM has been describing theirs? Does "biomass agnostic" ring a bell?
