Characterization, genetic variation, and combining ability of maize traits relevant to the production of Cellulosic Ethanol
Maize (Zea mays L.) stover has been identified as an important feedstock for the production of cellulosic ethanol. Our objectives were to measure hybrid effect and combining ability patterns of traits related to cellulosic ethanol production, determine if germplasm and mutations used for silage production would also be beneficial for feedstock production, and examine relationships between traits ...

State and federal subsidies to biofuels: magnitude and options for redirection
Hundreds of government subsidies have fuelled the growth of ethanol and biodiesel in the USA, worth half or more their retail price. Cumulative costs under some mandate proposals exceed $1 trillion by 2030. Even using favourable assumptions, reduced greenhouse gas emissions from biofuels are far more expensive than other options: more than $100/mt CO2e even for cellulosic ethanol and nearly ...

How is Ethanol Produced?
What is ethanol? Ethanol is an alternative fuel made from corn, sugarcane, wheat, and other agricultural products, and is produced by the fermentation of carbohydrates such as sugar, starch, and cellulose. Ethanol Feedstocks All plants contain sugars that can be fermented to make ethanol in a process called biochemical conversion. Plant material can also be converted to ethanol using heat and ...

EPA trims 2014 Renewable Fuel Mandate to 15.21 billion gallons, viting blend wall
The Environmental Protection Agency proposed Nov. 15 to use its waiver authority for the first time to reduce the overall renewable fuel blending requirement for 2014. The proposed rule for the 2014 renewable fuel standard would require petroleum refiners and importers to blend 15.21 billion gallons of renewable fuels into their products. That is down from the 18.15 billion gallons required by ...

Do not overlook your business’ intellectual assets
Intellectual property (IP) plays a vital role in all industries, from manufacturing processes to commercial products, phones to pharmaceuticals and everything in between. And the waste management field is no exception—especially as more environmentally-friendly and more efficient means of waste disposal are invented. In almost every business—even those that are thought of as ...

Algae biofuel can cut CO2 emissions by at least 50% petroleum fuels
PRESTON, Minn., Sept. 20 (UPI) -- Algae-derived biofuels can reduce the life cycle of carbon dioxide emissions by at least 50 percent compared to petroleum fuels, a U.S. university study found. The peer-review study -- the first to analyze real-world data from an existing algae-to-energy demonstration scale farm -- indicates the environmental and energy benefits of algae biofuel are at least on ...

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 ...

Lignin: A Possible Substitute for Petrochemicals in Products - Videos
Usually burnt to heat the facilities at pulp and paper-making operations after valuable carbohydrate components such as cellulose have been separated from the woody feedstock—and sometimes cursed for its tendency to stick like glue to the other components of the wood—the polymer lignin, making up almost a third of the wood in trees, has become hot property in research and development ...
