The Gamut

By Ron Kotrba | March 19, 2012

With its two columns in this issue of Algae Technology & Business, the National Alliance for Advanced Biofuels and Bioproducts covers the gamut in commercial product development from algae. Authors M. L. Drewery and T. A. Wickersham from Texas A&M give us, “Cattle: A Potential Market for Post-Extraction Algal Residue,” an article that delves into the authors’ ongoing research regarding the nutritive value of post-extraction algal residue (PEAR), and its palatability and effect on digestion and absorption of dietary nutrients in cattle. Read the entire article on page 6.

At the other end of the spectrum, F. Stephen Lupton, a senior research associate with Honeywell’s UOP, discusses his company’s work in his article, “The Refining of Algal Oils into Fungible Transportation Fuels,” mainly renewable diesel and biojet. Lupton writes about the hydrotreatment process and coproduction of naptha, light fuel gas, jet fuel and renewable diesel.

Drewery and Wickersham mention in their column that the U.S. DOE estimates 4.3 million tons of PEAR is produced for every billion gallons of fuel, or approximately 3.33 million tons, from algae. It is a wise move to generate data and knowledge of algae residue before high-volume fuel commercialization floods the market with product no one knows what to do with.
