TMO Renewables has announced they are making headway with producing pilot scale levels of ethanol from cassava stalk. The company is working with several Chinese fuel and food producers. TMO estimates that they will be able to produce a gallon of ethanol for less than two dollars, an important step for commercialization of fuels using advanced feedstocks.
The company has developed a technology platform that can break down a large number of different types of biomass into cellulosic
ethanol. The per gallon prices are nearing a point of competitiveness, TMO says, due to their ability to reduce costs through savings in maintenance, production time and capital expenditures. They have also been able to reduce costs through enzyme loadings. When using cassava stalk, TMO is predicting their conversion process will yield 70 to 80 gallons of ethanol per ton of feedstock.
“The total global capacity for 2G biofuels should reach more than 4 billion gallons by 2015,” said Pavel Molchanov, energy analyst at Raymond James. “Crucial to even greater production of cellulosic ethanol is the availability of diverse feedstock options, and cassava stalk can play an important role in the Asian market.”
TMO’s bread and butter partners have been the Chinese who developed the first industrial-scale biorefinery using cassava. TMO is currently finalizing its process design at its demonstration facility. Once achieved, the company will begin moving forward with plans to expand to commercial scale production.


President Obama made up a “to-do list” for Congress 
The 2012 CUTC agenda features cutting-edge technologies and new uses that are positioned change the corn industry. Among the session topics is Advance Biofuels, which will highlight some of the most recent research on advanced biofuels. Speakers will cover thermochemical and biochemical and biomimetic routes to the pretreatment and hydrolysis of lignocellulosics (such as corn fiber hulls, corn stover, etc.) to produce sugar and phenolic monomers that can be further upgraded to synthetic fuels, bioethanol, and/or chemicals.
“In spite of the wettest weather of the spring, producers in the Midwest still managed to plant a significant acreage of corn and soybeans” last week, says USDA Meteorologist Brad Rippey. “Corn emergence was greatly benefited by the rain and continuing warm weather.” Nearly a third of the crop is emerged nationwide, compared to the average of 13%. Last year, just six percent was emerged by this time.
While the industry is moving steadily toward the 15 billion gallon corn ethanol cap under the Renewable Fuel Standard (RFS2), Glauber says right now the market is steady at about 10 percent of ethanol blended fuel and getting E15 in the marketplace is moving slowly toward reality. “But you still have the underlying economics of whether or not a gas station is going to change over equipment to be able to sell E15,” he said. “The likely thing would be so-called blender pumps, which are expensive propositions.”
