Its really too bad the economics don't work. Had some hope for this one.
The Carthage plant has been optimized and is expected to turn a small profit. A tax credit has leveled the playing field with other renewable fuels like biodiesel and ethanol.
The fuel Appel makes, known officially as renewable diesel, received a subsidy of $1 per gallon from the Energy Policy Act of 2005, which took effect in January. That boosted the company's income by $42 a barrel, allowing a slim profit of $4 a barrel.
