Organic Waste to Resources Research and Pilot Project Report: Waste to Fuels Technology: Evaluating Three Technology Options and the Economics for Converting Biomass to Fuels

April 14, 2009

Hayk Khachatryan, Ken Casavant, and Eric Jessup, Jie Chen, Shulin Chen, and Craig Frear, September 2009. This study further investigated biomass from the 2005 biomass inventory by comparing three fuel technologies: cellulosic biomass conversion by fermentation for ethanol, or gasification for mixed-alcohols, and anaerobic digestion of high volatile solids biomass for methane production. The study […]

Organic Waste to Resources and Pilot Project Report: Biodiesel and Biohydrogen Co-Production with Treatment of High Solid Food Waste

April 14, 2009

Yubin Zheng, Jingwei Ma, Zhanyou Chi, and Shulin Chen, September 2009. two-step process was developed as a potential technology to produce hydrogen and biodiesel from food waste. The first process use fermentative bacteria to breakdown glucose from food waste to produce hydrogen and volatile fatty acids (VFA). The VFA are then fed to yeast for […]

Organic Waste to Resources Research and Pilot Project Report: New Biorefinery Concept to Convert Softwood Bark to Transportation Fuels Final Report to the Washington State Department of Ecology

April 14, 2009

Manuel Garcia-Perez, Shulin Chen, Shuai Zhou,Zhouhong Wang, Jieni Lian, Robert Lee Johnson, Shi-Shen Liaw and Oisik Das, September 2009. This project tested a new pretreatment concept to enhance the production of sugars from the fast pyrolysis of wood and straw. It proved that sugars recovered from pyrolysis can be easily converted into ethanol. These two […]

Biomass Inventory Technology and Economics Assessment

April 14, 2007

Liao W., C. Frear and S. Chen, June 2007. This project compiled a literature search for biomass chemical characterization and conducted supplemental laboratory study of forty two feedstocks for 33 parameters such as dry matter, COD, carbohydrates, lipids, elemental and mineral matter, and standard properties such as protein, fiber, pH, etc. A follow-on report will […]
