I have researched their process, at least that which isn't covered under "trade secrets". I have also researched biomass burning and urea production. Unfortunately, there are no studies about the effects of urea inhalation. I guess Taylor County residents will become the guinea pigs for that study if the plant is even built. I also know all biomass in this area is being used by Buckeye. When you add the cost of shipping biomass 100 miles (which is the approximate distance their biomass supplier is from here), the cost of the "cheap" biomass rises considerably, and is no longer economically feasible.
As for a decade, excuse me, it's only been about 7 years since they announced they would be building in Lubbock.
