Beef Ranches as Biodiesel Refineries

humphreyThe next set of biodiesel refineries will probably continue to be in rural America, but they might be part of livestock operations. This article from says Arkansas State University researcher Kevin Humphrey sees real potential for ranchers to produce their own biodiesel from oil seed crops, waste oil or tallow:

“If all you want to do is extract oil and meal, you can do that. If you want to extract and produce meal and then also produce biodiesel, you can do that,” he says.

Humphrey is using waste oil and oil seed crops — soybeans, canola, and camelina — to make biodiesel. He adds he hasn’t used animal fats but that is a viable option.

Matt Roberts, vice president of marketing for Springboard Biodiesel, says if the oil is collected free, as might be beef tallow from rendering, the biodiesel will cost about 95 cents per gallon to make. That price includes the cost of the chemicals to make the biodiesel — methanol, lye, and sulfuric acid.

The article goes on to point out that with many of the biodiesel feedstock oilseeds, especially soybeans, the resulting meal from the crush is a high quality feed. Plus, the glycerin from biodiesel production can be a livestock feed and an ingredient in soaps, lotions and lubricants.

The author also spoke with Darrell Wood, cattle rancher and owner of Leavitt Lake Ranches in Vina, California, who believes a ranch-based biodiesel refinery might just make his place more sustainable.

“It just opens the door for all kinds of possibilities,” Wood says.
