Lifecycle of Commercial Biodiesel

Audio/Video Script:

Commercial grade biodiesel is a federally recognized non-toxic, alternative transportation fuel that can be used as a replacement for diesel. It is an energy efficient option for decreasing the nation’s dependence on foreign oil while reducing harmful air emissions. There are several processes a manufacturer must address when making commercial grade biodiesel.

 Feedstocks, on average, account for about 85 percent of a cost of a gallon of biodiesel. There are a number of feedstocks that biodiesel can be made from.  Virgin vegetable oil such as soybean oil or canola oil, corn oil. There are fats involved, animal fats involved such as tallow, lard or poultry fat. And then of course there are waste products, corn oil from say an ethanol production facility or yellow grease, which is used cooking oils. So, biodiesel can be made from any of those oils and can be made to meet all ASTM specifications.

The facility that we run has been vetted to produce biodiesel from anyone of eight different feedstocks. Those eight are five vegetable oils or three fats.  Corn oil, palm oil, soybean oil, canola and cottonseed oil, as well as beef tallow, pork lard, and poultry fat. Ultimately the feedstock that you choose, you choose based on the economics at the time. Some oils cost more than others at various times in the market place. Right now we’re making almost everything out of tallow and we have plans in the very near future to switch over to corn oil and yellow grease, and that’s based on economics.

The production of commercial grade biodiesel, as I said before, is not much different than the chemistry required even on the simplest level. But what is required is a greater degree of attention to detail and a greater focus on economy of scale. The biodiesel is made through transesterification, being able to use any kind of biodiesel may require you to do a number of steps on the front end to pretreat your biodiesel, your feedstock, before you actually take it into production. You can go through what’s called a water-wash system, which is what we have chosen to do. And, by the way, I think a water-wash provides a higher quality biodiesel on the end of production. The water-wash basically water simply washes away all the impurities leaving just the methyl-ester and, of course, you do have to do something with the wastewater when you’re done. So, we take that approach in our commercial grade and produce a biodiesel that we think meets, certainly meets all ASTM and it’s a very high quality product.

At present, our production capacity is about 59 million gallons per year and we are running at rate. The biodiesel that we produce, we have the ability to put in storage or sell directly to customers, either by rail or by truck. Biodiesel blends are the percentage of biodiesel relative to the ultra-low sulfur diesel present. It could also be low-sulfur diesel but I think most low-sulfur is gone now from the marketplace so let’s just focus on ultra-low.

B 100 is a 100 percent biodiesel, no diesel. B 99.9 is essentially a 100 percent biodiesel with just a very small amount -- one gallon of ultra-low sulfur diesel per thousand gallons of biodiesel – and that’s done for distribution of the tax credit, so that it can go to the producer or the blender.

We have never recommended at Future Fuel using more than a B 20 blend. You get your best economics, you get your best engine performance, and it’s accepted by a great many warranties, original equipment manufacturer warranties, and it probably has the best year-round characteristics. So B 20 is the most. But we have a great many customers who use B 50. They use them in their irrigation pumps in the rice fields, as well as customers, farmers who use B 99 and they use in their tractors and heavy equipment combines what have you and love it and have had no problems with it. We don’t recommend that, but then again you don’t do that kind of farming in the winter anyway. And as you well know there are always issues around wintertime use, fitness for use with biodiesel, because of its cloud point being higher than diesel fuel.
