Turning Wastewater into Ethanol - In a two-step process, Israel-based Applied Clean Tech start by removing cellulose (the part of the plant we can’t digest) from both the sludge and agricultural liquid waste, then Massachusetts-based Qteros ferments this treated material into cellulosic ethanol using a fast-acting microbe, solving the headache of sewage sludge disposal, providing a solution for wastewater treatment plants. (Alt Energy News; Oct. 19, 2009)
- Cellulosic Ethanol on the Cheap - Mascoma, a cellulosic biofuels company based in Lebanon, NH, reports significant advances in its goal of simplifying the cellulosic ethanol process by skipping the use of costly enzymes, which could potentially reduce cellulosic ethanol's production costs by 20 to 30 percent. (MIT Technology Review; May 12, 2009)
- New Potential Ethanol Feedstock Pursued by Retired Florida Minister - Preliminary tests show that the Rev. Giok Se Tijong "Tijong grass" -- a cross between sugar cane and elephant grass -- developed in the 1950s, has a high carbohydrate content (71.26%), ideal for ethanol production. (TreeHugger; August 4, 2008)
- A Better Biofuel Bug - Zymetis has genetically modified a rare, cellulose-eating bacterium to break down and convert cellulose into sugars necessary to make ethanol, and it recently completed its first commercial-scale trial. (MIT Technology Review; March 18, 2009)
- New biomass technology dramatically increases ethanol yield from grasses and yard waste - The new technology features a fast, mild, acid-free pretreatment process that increases by at least 10 times the amount of simple sugars released from inexpensive biomass for conversion to ethanol and eliminates the use of expensive and environmentally unsafe chemicals currently used to pretreat biomass. (PhysOrg; July 28, 2008)
- Cellulosic Ethanol Plant Opens - A 1.4 million gallon demonstration-scale plant in Jennings, LA will use waste biomass to make biofuel. (MIT Technology Review; May 28, 2008)
- Is vinegar the secret ingredient for biofuels? - ZeaChem says it has come up with a method of making cellulosic ethanol that results in close to 40 percent more fuel per ton of wood chips than competing processes, and at a price at the pump of around $1.10 to $1.50. See Video. (CNet News; March 12, 2008)
- Hydrogenolysis Process for Cellulosic Ethanol - ZeaChem combines the output of fermentation and gasification into hydrogenolysis, for the production of ethanol from cellulosic biomass feedstocks. ZeaChem claims that its technology will produce 50% more ethanol per ton of feed and results in an energy output that is more than ten times greater than the input. (Green Car Congress; Jul. 2, 2007)
- Heat-Seeking Bacteria Could Hold Key to Better Cellulosic Ethanol - TMO Renewables believes it has found the silver bullet of cellulosic ethanol production: an organism that eats nearly anything and makes ethanol really quickly. The heat-seeking rod-shaped bacterium thrives in high temperature conditions and is 300 times more effective at making ethanol than its wild strain counterpart. (TreeHugger; Aug. 24, 2007)
- Biofuels from Wood Chips - Three University of California campuses and West Biofuels LLC, will develop a prototype research reactor to make biofuels without food crops or microbial fermentation. It will use steam, sand and catalysts to efficiently convert forest, urban, and agricultural “cellulosic�? wastes into alcohol that can be used as a gasoline additive. (PhysOrg; Jun. 12, 2007)
- Brelsford Engineering Inc - BEI is offering a new and efficient dilute-acid chemical process for the conversion of waste cellulose into fermentable sugars and subsequently into bio-ethanol. Capital costs are about 50% of those for comparable dilute concentrated acid, or enzymatic, cellulose hydrolysis processing. Small farm scale fuel ethanol plants can now be economically profitable.
- Cellulosic ethanol breakthrough - Brazil's Dedini SA announced it has come up with a way to produce cellulosic ethanol on an industrial scale from plant waste, at a cost of US 27 cents a liter (US$ 1.02 per gallon). This development could revolutionize the industry, making it cost-competitive with oil at US$42 a barrel. (Biopact; May 16, 2007)
- BTX starch separation from wheat straw verified - Starch was extracted from wheat straw with the 'Hypercritical Separation Technology', a dry mechanical system to separate biomass on a molecular level, while utilizing very little energy and emitting no waste product. The HST system concentrates the starch and sugar fractions to produce feedstock for cellulosic ethanol. (Biopact; Feb. 15, 2007)
- First US Cellulosic Ethanol Plant - Celunol achieves high ethanol yields from cellulosic biomass at costs competitive with conventional sugar and starch feedstocks. Its 50,000 gallon pilot facility commenced operation in November 2006 and a 1.4 million gallon facility is targeted for completion in mid 2007. (The Energy Blog; Feb. 8, 2007)
- Wood-based Ethanol Plant Slated for Georgia - Range Fuels will build a cellulosic ethanol plant using wood waste from Georgia Pine as the main source of biomass. Its two-step thermo-chemical conversion process to convert biomass into a synthetic gas and then gas to ethanol, eliminates the use of expensive enzymes. (Renewable Energy Access; Feb. 8, 2007)
- Mascoma - Cellulosic biomass has a cost per BTU equivalent to oil of about $14/barrel. Recent advancements in enzymes, organisms and production technologies allow cost-effective ethanol production from inexpensive cellulosic biomass (grass, wood, agricultural and forestry wastes).
- Diversa - Developing enzymes that convert renewable resources, such as corn and cellulosic biomass, into renewable fuels, such as ethanol and biodiesel. Valley "Ultra-Thin™" enzyme, for the conversion of corn into ethanol, is on the market today and a set of enzymes has been developed for an economical, commercial-scale process to convert starch and cellulosic biomass to fuel ethanol.
