Building Sustainable Farms, Ranches and Communities: A Guide to Federal Programs....

U.S. Department of Agriculture and various other organizations, Oct. 2014.
https://attra.ncat.org/attra-pub/summaries/summary.php?pub=279

"This guide is written for anyone seeking help from federal programs to foster sustainable and innovative initiatives in this country associated with agriculture and forestry. Sustainability is commonly understood to embrace the triple concepts of economic, environmental and social viability. Specifically, the guide provides information about program resources pertaining to economic development, farm loans, insurance and risk management, natural resources conservation and management; nutrition and consumer food access, renewable energy and energy conservation, research and outreach, and value added and marketing innovations."


Research Aims to Help Dairy Farmers Generate Sustainable Energy

Nevada Today, University of Nevada, Reno, Oct. 1, 2014, by Kirstin Swagman.
http://www.unr.edu/nevada-today/news/2014/sun-grant

"A new, collaborative grant at the University of Nevada, Reno will further research into biomass conversion by developing a cost-effective process for large-scale dairy farmers to generate energy from manure.

The University's new grant, "Sun Grant: Power/Waste Biomass," totals more than $600,000 over two years, with the bulk of the funds coming from the U.S. Department of Agriculture."


Evaluating Farm Slurry Extends Life & Performance [Pumps]

Pumps & Systems, Sept. 2014, by Paul Davies.
http://www.pump-zone.com/pumps/september-2014-evaluating-farm-slurry-extends-life-performance-0

"Pump manufacturers know that the engineering phrase “fit and forget” never holds true for rotating equipment. For all its reliability and longevity, a slurry pump that has been operating in a pit for several years will eventually fail. Several pumps can handle farming applications at a tenth of the initial cost for an application-specific slurry pump. However, replacing a cheaper, less effective pump every six months becomes a tiresome—and expensive—hassle for many farmers. This article features several examples of how selecting the right pump ensured worry-free operation in harsh pit service."

Digested Dairy Manure to High-End Potting Soil

BioCycle, July 2014, by Nora Goldstein.

"An anaerobic digester development company launched a bagged potting soil product to utilize digested dairy manure fibers and improve long-term success of facilities....when falling rates for renewable energy and the loss of the federal Investment Tax Credit grant hit at the same time."

North Dakota's Subterranean Fuel Feedstock

Biomass Magazine, June 2014, by Chris Hanson.
http://biomassmagazine.com/articles/10458/north-dakotas-subterranean-fuel-feedstock

"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)

BioCycle, June 2014, by Nora Goldstein.

"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."


High Solids Anaerobic Digestion + Composting in San Jose

BioCycle, Mar./Apr. 2014, by Nora Goldstein.
http://www.biocycle.net/2014/03/28/high-solids-anaerobic-digestion-composting-in-san-jose/

"A facility that marries dry anaerobic digestion and composting under the same roof to process the organic fraction of municipal solid waste opened for business late last year at the south end of the San Francisco Bay in San Jose, California. Zero Waste Energy Development Company (ZWEDC) — developer and owner of the 90,000 tons/year facility — recognized the benefits of colocation to enable extraction of the energy value of the food waste, followed by composting of the digestate. The plant, comprised of 16 high-solids dry fermentation digesters and four in-vessel composting tunnels, began receiving organics from the commercial sector in San Jose in mid-December."

From Cow to Car [Manure to CNG]

Manure Manager, Mar./Apr. 2014, by Diane Mettler. http://www.mydigitalpublication.com/publication/index.php?i=0&m=1559&l=1&p=6&pre=&ver=flex

"Using their 6.2 million gallon digester, Fair Oaks Farms [Fair Oaks, IN] has converted waste into enough compressed natural gas (Cng) to run their fleet of milk trucks."
