Terrabon Dedicates Biofuels Research Facility in Texas

November 17, 2008

BRYAN, TX --- Terrabon L.L.C. held dedication ceremonies Friday, Nov. 7, for its new advanced biofuels research facility in Bryan, Texas, about 70 miles northwest of Houston.

The company aims to use the new facility to confirm the scaled-up, commercial feasibility of its MixAlco technology, which converts low-cost, non-food biomass into chemicals that can be processed into renewable gasoline.

Speaking at the event, Texas Gov. Rick Perry said: "Energy independence has become a critical goal as the worldwide demand for energy continues to rise and traditional energy sources can no longer be solely depended on to provide the resources needed. To advance the next generation of energy technologies, we must continue to develop and refine new ideas and take some risk to produce and market them through innovation and competitive markets."

The governor said that energy independence would not be achieved through government regulations and taxes. "We are making great strides in renewable sources like biofuels because private-sector companies like Terrabon are risking their own capital on great ideas," he said. "In the same way that Texas long ago set the pace in petroleum production and refining, we are now leading the way into a new era of renewable energy production, which will move us closer to energy independence."

The MixAlco technology was developed by a research group headed by Mark T. Holtzapple, professor at the Artie McFerrin Department of Chemical Engineering at Texas A&M University. "Compared to competing biomass-conversion processes, MixAlco is a simple technology that was inspired by the digestive system of the ordinary cow," Holtzapple said. "Unlike current alcohol technology, which uses food grains to produce liquid fuels, MixAlco uses any biomass, including municipal solid waste, sewage sludge, manure, agricultural residues, and energy crops. The biomass is placed in a large, oxygen-free tank, analogous to the rumen (or first stomach) of cattle, where naturally occurring organisms convert the biomass to vinegar. No sterility is required and no enzymes must be added."

Holtzapple noted that MixAlco exemplifies the term "biorefinery" because of the wide variety of chemical and fuel products that can be produced using the technology. The vinegar produced by MixAlco can be used to make plastics, or it can be chemically converted to other chemicals such as acetone. By adding small amounts of hydrogen, alcohol fuels can be made that have higher energy content than conventional ethanol. The alcohols can be further converted to gasoline that is virtually identical to conventional gasoline made from crude oil.

The new research facility continues the work conducted at the pilot plant in College Station, which has been testing the MixAlco technology for more than three years. The pilot plant can process up to 100 dry pounds per day of biomass using feedstocks such as paper wastes and chicken manure. Sorghum will be the primary feedstock at the demonstration scale facility, which has a loading capacity of 400 dry tons of biomass.

Terrabon plans to joint venture and license its technologies with other companies and municipalities.
