"rising cost of feedstock is adversely affecting the Company's
profitability in its biodiesel business"

This is the biggest problem. IMO they will always run behind those costs, never get ahead. And that is the limit for their grow as well as for investors. I am on sideline here, still watching it, but their business model is not very catchy.
Tax issue is great to be solved. But that was a partial problem. They must be much cheaper than ordinary oil. If they do now, they will have low margin. If they increase the margin, they will have no sales.

But maybe I am wrong.
