Colorado has been particularly affected by the pine beetle epidemic with entire pine forests being killed completely. (The trees in red are dead.)
(Credit: Office of Congressman John T. Salazar, D-Colo.) Fuel start-up Cobalt Technologies has figured out a way to use trees poisoned and killed by pine beetles to make biobutanol, the company announced Wednesday.
Cobalt develops biofuels that can be mixed with gas, diesel, or jet fuel, as well as used to make plastics. Up until now, the company has used forestry byproducts that originated from healthy trees to make its n-butanol. The result is a gasoline blend made up of 12 percent biobutanol, which the company has claimed can reduce greenhouse gas emissions by up to 85 percent when compared to conventional gasoline. It's been touting the fuel as an alternative to ethanol, and in January launched a California plant with the support of Gov. Arnold Schwarzenegger.
The company's process for making biofuel from the unhealthy wood is quite similar to the fermentation procedure Cobalt has used on other nonfood biomass. It applies its own proprietary strains of bacteria to ferment the biomass and convert it to n-butanol with one important exception. Because the sap from the beetle-killed trees is a toxin, the scientists first apply a "pretreatment process" to extract the sap from the dead pine before breaking it down. The heat given off from that pretreatment is directed toward the fermentation process to further save energy, according to Helen Allrich, a spokeswoman for Cobalt.
Colorado State University has agreed to partner with Cobalt to test how well gasoline blended with the biobutanol will perform in engines.
"If Cobalt can convert beetle-killed wood, it's likely that the company can make biofuel from almost any cellulosic feedstock," Ken Reardon, professor of Chemical and Biological Engineering at Colorado State University, said in a statement.
As it's been widely reported, the Mountain pine beetle and other pine beetles have been a nuisance to forests across the U.S. and Canada, particularly in Colorado and British Columbia. If testing goes well, it could offer a significant opportunity to turn a negative situation into a useful one.
"If we use only half of the 2.3 million acres currently affected in Colorado alone, we could produce over two billion gallons of biobutanol--enough to blend into all the gasoline used in Colorado for six years," Rick Wilson, chief executive officer of Cobalt, said in a statement.

Ethanol alternative gains ground with new plant

Cobalt's facility restricts water consumption by recycling water used in its fermentation process.

Biobutanol, butanol made from biomass as opposed to fossil fuels, already has approval for use in fuel blends for vehicles under U.S. Environmental Protection Agency guidelines.
Cobalt and others have claimed that biobutanol has an advantage over ethanol, which has been known to have corrosion issues in some older fuel systems and pipelines and is conventionally used in fuel blends and in newer cars with ethanol-ready engines. Biobutanol can be used as a standalone fuel even in conventional gasoline car engines, in addition to being used in gasoline and diesel fuel blends.
Cobalt's current biobutanol/gasoline blend, which mixes 12 percent biobutanol with conventional gasoline, reduces greenhouse gas emissions by as much as 85 percent compared to conventional gasoline, according to Cobalt company statistics.
Biobutanol may have another advantage over ethanol. It can be made from inedible wood and plant waste.
While the production of cellulosic ethanol--ethanol produced from forestry or agricultural waste--is predicted to increase, much of the world's ethanol is still produced from corn and grain. Many remain concerned that ethanol has caused soaring food prices and shortages, since food producers are forced to compete against energy companies for grain supplies.
Biobutanol can also be converted into jet fuel or used in plastics and paint products.
"We are on track to build a commercial facility within two years, and we are currently building a network of strategic partners in the fuels, chemicals, forest products, and construction industry to deploy our technology at the next scale," Cobalt Biofuels CEO Rick Wilson said in a statement.
California Governor Arnold Schwarzenegger, who clearly sees Cobalt as a poster child for clean-tech investment in his state, attended the press conference in part to push his initiative to pass legislation exempting sales tax on green manufacturing equipment.
In addition to making biofuel for cars that meets California's low carbon fuel standards, the company will provide the state with some much-needed jobs.
"Cobalt shows us that what is good for the environment can also be good for the economy. In fact, within the next few years, Cobalt has plans to build an even larger plant that will create 1,300 permanent jobs," said Schwarzenegger.
Schwarzenegger is not the only one singing Cobalt's praises.
The Mountain View, Calif.-based company was one of 34 companies picked by the U.S. Department of Energy's National Renewable Energy Laboratory forum in 2008 as an example of a viable renewable energy company. Cobalt also received $25 million in Series C funding in October 2008 from a group of investors that included Pinnacle Ventures.
And Cobalt is not the only company looking to produce a low-carbon butanol from non-feedstock biomass.
In August 2009, oil giant Total announced it was investing in Gevo, a Colorado-based company developing biobutanol made from sugarcane or agricultural byproducts. Though it's more of a research and development facility than an actual plant, materials science giant Dupont has partnered with BP on a biobutanol plant in the U.K. And earlier this month, Canadian start-up Syntec Biofuel announced plans to develop a biobutanol made from wood and agricultural waste in partnership with the Energy & Environmental Research Center at the University of North Dakota (UND).
