EPA announces 2014, 2015, and 2016 RFS volumes
The U.S. Environmental Protection Agency (EPA) has proposed the volume requirements and associated percentage standards that would apply under the RFS program in calendar years 2014, 2015, and 2016 for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel. We will include a complete analysis of the EPA proposal and its impact in the June 4, 2015, Biobased and ...

Overview of biomass and bioenergy sources in northern B.C.
Ibrahim Karidio identified four groups of biomass sources: cellulosic materials from wood residues, agricultural crops, animal wastes, and municipal and industrial solid wastes. “B.C. has a huge land mass,” Karidio said. Of the total provincial annual allowable cut, 47% comes from the Northern Interior. B.C. generates 31% of Canadian wood residues and 66% of Canadian surplus wood residues. ...

EPA Close To Publicizing 2017 And 2018 Renewable Fuel Standard Volumes
On April 15, 2016, the U.S. Environmental Protection Agency (EPA) sent its newly proposed Renewable Fuel Standard (RFS) volumes for 2017 and 2018 to the U.S. Office of Management and Budget (OMB) for review. Under the Clean Air Act (CAA), EPA must set standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel by November 30 of the year before the standard ...

Effect of initial biomass on cellulose hydrolysis by leachate communities
Batch anaerobic digestions were performed in 160 ml serum vials, cellulose (1% wt) was the sole added carbon source. All reactors were inoculated with a 10% (v/v) leachate inoculum. The concentration of micro-organisms in the leachate inoculums was increased using centrifugation to investigate the effect of initial biomass on hydrolysis performance. The hydrolysis rate constant for digestions ...

Liquid fuels from woody biomass
Although challenges like global climate change and oil depletion will increasingly drive fuel selection, increasing bioenergy use is only one of many possible responses to these problems. Present biomass liquid fuels are almost all derived from food crops, but their potential for further expansion is limited. Any major expansion of biomass liquid fuels will require use of the more abundant ...

Converting plant waste into biofuels
Promising advances using yeast and fungi. Written by Nancy W. Stauffer. You can read the original story in MIT News MIT researchers are genetically engineering yeast to break down stubborn plant fibers into sugars that it can then ferment — a first step toward a potentially cost-effective single-organism process for manufacturing cellulosic biofuels. The source of the genetic material: ...

Hydrogenomics of the extremely thermophilic bacterium caldicellulosiruptor saccharolyticus
Caldicellulosiruptor saccharolyticus is an extremely thermophilic, gram-positive anaerobe which ferments cellulose-, hemicellulose- and pectin-containing biomass to acetate, CO2, and hydrogen. Its broad substrate range, high hydrogen-producing capacity, and ability to coutilize glucose and xylose make this bacterium an attractive candidate for microbial bioenergy production. Here, the ...
