Ethanol producer to integrate renewable diesel production from corn distiller oil

July 25, 2014

Ethanol producer East Kansas Agri-Energy LLC (EKAE) intends to integrate renewable diesel production at its ethanol plant in Garnett, Kansas. Renewable diesel will be made from the corn distillers oil (CDO) already produced at the plant along with other feedstocks purchased on the market. WB Services is the technology provider for the catalytic renewable diesel process.

Construction on the new facility will begin soon and will be complete in about 12 to 14 months. The plant will be able to produce three million gallons of hydrocarbon fuel per year, with the ability to double that capacity in the future. The plant currently produces some 40 million gallons of ethanol; 200,000 tons of the livestock feed distillers grains; and 5 million pounds of corn oil each year from more than 16 million bushels of locally-sourced corn.

Roadmap shows how to improve lignocellulosic biofuel biorefining with high-value products from isolated lignin

May 19, 2014

A new review article in the journal Science highlights emerging opportunities to increase the transformation of lignin to value-added products—i.e., lignin valorization. The resulting roadmap uses the integration of genetic engineering with analytical chemistry tools to tailor the structure of lignin and its isolation so it can be used for materials, chemicals and fuels, said lead author Arthur Ragauskas, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology.

Potential high-value products from isolated lignin include low-cost carbon fiber, engineering plastics and thermoplastic elastomers, polymeric foams and membranes, and a variety of fuels and chemicals—all currently sourced from petroleum. Each product stream, however, has its own distinct challenges.

A team from seven US universities and the Korea Institue of Science and Technology, led by George Huber, Professor of Chemical and Biological Engineering at the University of Wisconsin-Madison, has developed an integrated catalytic process for the conversion of whole biomass into drop-in aviation fuels with maximal carbon yields.

The researchers expect that in its current state, the proposed technology could deliver jet fuel-range liquid hydrocarbons for a minimum selling price of $4.75 per gallon—assuming nth commercial plant that produces 38 million gallons liquid fuels per year with a net present value of the 20 year biorefinery set to zero. Future improvements in this technology, including replacing precious metal catalysts by base metal catalysts and improving the recyclability of water streams, could reduce this cost to $2.88 per gallon.

DEINOVE produces ethanol at 9% titer with its optimized Deinococcus bacteria

January 16, 2014

DEINOVE, a technology company that designs, develops and markets a new generation of industrial processes based on optimized Deinococci bacteria, has produced ethanol at a titer of 9% via its fermentation of biomass sugars in 20L pre-industrial fermentors. In September 2012, the company had reported that its optimized strain of Deinococcus generated ethanol from wheat-based biomass with a titer of 3%. (Earlier post.)

The 9% content v/v (volume/volume)—equal to 7.2% wt/v (weight/volume)—exceeds the 5% alcohol content wt/v considered to be the threshold for industrial exploitation of a process for 2nd generation biofuels, the company said. The obtained performance is gradually approaching the maximum theoretical yield, the company added. The use of Deinoccoccus offers several benefits:

UCLA engineers develop new metabolic pathway for more efficient conversion of glucose into biofuels; possible 50% increase in biorefinery yield

October 01, 2013

Researchers at UCLA led by Dr. James Liao have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50% increase in the production of biofuels. The new pathway is intended to replace the natural metabolic pathway known as glycolysis, a series of chemical reactions that nearly all organisms use to convert sugars into the molecular precursors that cells need. The research is published in the journal Nature.

Native glycolytic pathways—a number of which have been discovered—oxidize the six-carbon sugar glucose into pyruvate and thence into two-carbon molecules known acetyl-CoA for either further oxidation or biosynthesis of cell constituents and products, including fatty acids, amino acids, isoprenoids and alcohols. However, the two remaining glucose carbons are lost as carbon dioxide.

OIG audit finds DOE has not achieved biorefinery goals despite 7 years and $603 million spent

September 13, 2013

An audit report released by the Department of Energy’s (DOE) Office of the Inspector General (OIG) found that despite more than 7 years of effort and the expenditure of about $603 million, DOE had not yet achieved its biorefinery development and production goals.

Specifically, the audit found, the mandate to demonstrate the commercial application of integrated biorefineries had not been met and DOE was not on target to meet its biofuels production capacity goal. Although DOE’s Bioenergy Technologies Office (BTO) reported meeting its goal to demonstrate the successful operation of three integrated biorefineries by 2012, OIG noted that these biorefineries were primarily much smaller pilot projects rather than commercial scale.
