Mascoma Corp. says it has found a way to remove several steps from the process of making cellulosic ethanol, cutting the cost and time it takes to make the fuel, while increasing yields.
The Lebanon, N.H.-based company says it has made advances in consolidated bioprocessing, a process that uses engineered microorganism to make ethanol from cellulosic biomass, such as grasses, stalks and wood waste. Mascoma’s CBP process eliminates the need to produce costly cellulase enzymes, by producing the cellulase and ethanol in a single step.
Mascoma says they’ve achieved a 60% reduction in cost for their consolidated bioprocessing technology (CBP).
Mascoma Corp., a well-known firm pursuing the advanced production of cellulosic ethanol, announced today what they’re calling “major scientific advances” that will enable them to produce lower cost, lower carbon fuel from sustainable sources.
This is a true breakthrough that takes us much, much closer to billions of gallons of low cost cellulosic biofuels. Many had thought that CBP was years or even decades away, but the future just arrived. Mascoma has permanently changed the biofuels landscape from here on.
-Dr. Bruce Dale, Scientific Advistory Board of Mascoma
Mascoma’s value-proposition is to elminate as many steps as possible in the processing of non-food cellulosic feedstocks to produce ethanol. The consolidation of the process—which involves enzymatically breaking apart cellulose into sugars, and then fermenting the sugars into alcohol—dramatically reduces overall cost. CBP eliminates the need for added and costly enzymes to process pretreated lignocellulose into ethanol.

Researchers at Michigan State University have patented a process for pretreating corn crop waste that they say will cut the cost of making cellulosic ethanol and other biofuels.
Cellulosic ethanol is made from wood pulp, grasses and crop wastes. The technology promises better energy output than corn-based ethanol, at prices that could be cost-competitive with gasoline.
Ceres, Inc. supports the prediction that we could grow more than 30% of US transportation fuel with dedicated energy crops. This is no pipe dream: planting starts next spring.
Ceres, Inc., the self-described “energy crop company,” is engineering plants that could play a big role in the future of sustainable biofuels. In stark contrast to food crops, what Ceres is in the business of creating are “dedicated energy crops”—like switchgrass, sorghum, and miscanthus—that are ideally suited for fuel production.
While the global “food vs. fuel” debate rages on, a few companies like Ceres are quietly moving forward with next generation technology that challenges many of the current assumptions about growing fuel. In their view, it’s time to move the conversation on from corn-based controversy to second-generation, non-food based sources of ethanol.
Tomorrow, General Motors is hosting a backgrounder on cellulosic ethanol feedstocks at the Thousand Oak (CA) based laboratories of Ceres, Inc.
Coverage of non-food based ethanol tends to focus on fuel production technologies, but Ceres works one step further up the supply chain: they’re using genetic technology to engineer plants optimally suited for conversion into something you’d want to put in your gas tank.
I’ve already had the chance to speak with Richard Hamilton, President and CFO of Ceres, about the potential to produce super-strains of perennial grasses like sweet sorghum and switchgrass, and I’m looking forward to hearing more details tomorrow.
