Some of us at the shallow end of the gene pool are beyond help but thanks for laying things out nicely.
As I understand matters, BFRE's primary advantage is cheap, readily available materials without mention of the years of production of ethanol from refuse in Osaka's pilot plant.
They have mentioned in the past that they could easily produce biobutanol rather than ethanol so why the heck don't they? Butanol seems to have a great advantage over ethanol but the main problem I have seen mentioned is toxicity. Gasoline isn't toxic??? There is something there I am not getting. I suspect infrastructure and monopoly despite the involvement of at least one major oil company.
You may well have shot down any involvement of BFRE in converting sewage but it is hardly bereft of cellulosic matter.
