Regardless of the source of biofuel feedstock, the mass balance analysis always comes out negative as a large scale and  primary energy producer because biofuel feedstocks are ultimately dependent on NPK petro-chem based fertilizers. Unless a sustainable/renewable source of NPK is found (not even on the most distant horizon presently) – and one not based on petro-chems at all- biofuels are a non-starter as a primary energy source.

Biofuels as an energy scavenger in the 3% of our waste products estimated available to such technologies – biofuels will help improve the production economics of a very site and opportunity specific small set of industries. This isn’t just my conclusion,  but recent studies done by Kansas State U., MIT and the Rand Corp. have all come to the same basic conclusion.
