North Dakota's Subterranean Fuel Feedstock

Biomass Magazine, June 2014, by Chris Hanson.

"When the advanced biofuel industry thinks feedstocks, ideas may drift toward dried corn stover on a freshly harvested field, or swathes of switchgrass or miscanthus swaying in the breeze. In the Red River Valley and Drift Prairie regions of North Dakota, however, the next advanced biofuel might be found below the ground in the form of sugar beets. But why sugar beets?" Includes a table that shows U.S 10-Year Sugar Beet Production, by state.

Building Farm And Food Scrap Digesters (Part I)

"A steady stream of anaerobic digestion facilities are coming on line, most equipped to process food waste. This first of a two-part series profiles several farm digesters. Part I"

Biofuel Technology Goes Mobile [Pyrolysis]

WSU College of Agricultural, Human, and Natural Resource Sciences (CAHNRS), Press Release, Jun. 2014.
http://news.cahnrs.wsu.edu/2014/06/11/biofuel-technology-goes-mobile/

"Scientists like Manuel Garcia-Perez and his graduate students, who study biosystems engineering at Washington State University, are helping to nurture the emerging biofuels industry by developing pyrolysis technologies. Garcia-Perez and Geraldo Ferreira-David of Brazil calculate material entering and exiting the pyrolysis system."

Effect of the Type of Bean, Processing, and Geographical Location on the Biodiesel Produced from Waste Coffee Grounds

Energy Fuels, 2014, by Rhodri W. Jenkins, et. al.
http://pubs.acs.org/doi/pdf/10.1021/ef4022976

"Waste coffee grounds offer a viable waste feedstock for biodiesel production. Approximately 8 million tonnes of coffee are produced globally each year and contain up to 15 wt % lipid, of which the glyceride portion is predominantly made up of palmitic, stearic, oleic, and linoleic acids. In this investigation, the variation in the oil content, saponifiable lipids, and lipid profile according to the regional location and processing or brewing techniques was assessed. A number of key fuel properties were also investigated."


Biofuels Progress: Where Do We Stand?

"As ethanol stalls, the military and airlines push hard for new biojet fuels. Where will they come from?"

Poplars Designed for Deconstruction: A Major Boon to Biofuels

University of Wisconsin-Madison News, Apr. 3, 2014.
http://www.news.wisc.edu/22698

"What began 20 years ago as an innovation to improve paper industry processes and dairy forage digestibility may now open the door to a much more energy- and cost-efficient way to convert biomass into fuel.

Michigan State University Associate Professor and (GLBRC) scientist Curtis Wilkerson describes his and University of Wisconsin-Madison colleagues’ paper, appearing in the April 4 issue of Science, as 'a rare, top-down approach to engineering plants – in this case poplars – for digestibility

Iowa State Engineers Upgrade Fast Pyrolysis Pilot Plant

Biomass Magazine, Jan. 2014.
http://biomassmagazine.com/articles/9978/iowa-state-engineers-upgrade-fast-pyrolysis-pilot-plant

Fast pyrolysis is a pathway to advanced renewable fuels from cellulosic biomass like corn stover, which Iowa has a lot of, and switchgrass, which is well suited to Iowa’s climate and soils,” [Robert C. Brown] said. “What we learn in the lab can help companies commercially develop these Iowa resources.”
