Hi Frank Try these: Fuel From Sawdust -- by Mike Brown (from Acres, USA, 19 June 1983): Conversion of cellulose, such as sawdust, cornstalks, newspaper and other substances, to alcohol -- "a fairly uncomplicated and straightforward process". http://journeytoforever.org/biofuel_library/ethanol_sawdust.html Ethanol from cellulose "Wood-Ethanol Report: Technology Review", Environment Canada 1999 -- good overview of the problem and the current solutions on offer. http://www.pyr.ec.gc.ca/ep/wet/section16.html Arkenol Inc. is a pioneer in processing cellulose biomas into ethanol: agricultural wastes, straw, leaves, grass clippings, sawdust or old newspapers. The company uses proprietary concentrated acid hydrolysis technology and is in the final development stages for a 48 million litre per year biorefinery in Sacramento, California processing rice straw. http://www.arkenol.com The Iogen Corporation of Canada is "the leader in developing and manufacturing ethanol-from-cellulose". The Iogen process is an enzymatic hydrolysis process for converting lignocellulosics to ethanol -- uses steam explosion pretreatment pioneered by the company and Iogen's proprietary enzymes. http://www.iogen.ca/fuels.htm BC International Corporation uses a genetically modified organism to produce ethanol from biomass wastes such as agricultural residues, municipal waste, and forest thinnings. Two-stage dilute acid hydrolysis process for the preparation of the sugar streams and two separate fermentations although both use the same organism. http://www.bcintlcorp.com/ "Ethanol Production in Hawaii", a "pre-feasibility" study who a focus on ethanol from cellulose. Includes comparison of the different processes: simultaneous saccharification and fermentation; concentrated acid hydrolysis, neutralization and fermentation; ammonia disruption, hydrolysis and fermentation; steam disruption, hydrolysis and fermentation; acid disruption and transgenic microorganism fermentation; concentrated acid hydrolysis, acid recycle and fermentation; and acidified acetone extraction, hydrolysis and fermentation. http://www.hawaii.gov/dbedt/ert/ethanol/ethano94.html Good list of references: http://www.hawaii.gov/dbedt/ert/ethanol/refs.html Best Keith Addison Journey to Forever Handmade Projects Tokyo http://journeytoforever.org/ Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html To unsubscribe, send an email to: [EMAIL PROTECTED] Your use of Yahoo!
