As a matter of fact, the Renewable Fuels Standard (the 'Mandate') can be met with existing manufacturing capacity for at least the next couple of years.
Obviously, the bulk of this capacity is corn based, so the spoils will belong to whomever will be the leader in the cellulosic field.
There are some good resources on the RFA website, and you will find that it is unlikely that a small player like EVFL with a R&D spend of $0 over the past 3 years can be considered a leader in that space.
