Final Notes from BIO's World Congress

On June 29 at BIO’s World Congress, Steen Riisgaard, CEO of Novozymes, and Stephen Tanda, Board Member of Royal DSM N.V., released a report from the World Economic Forum on The Future of Industrial Biorefineries. The report says that a biorefinery value chain could create revenue for agricultural inputs ($15 billion US), for biomass production ($89 billion), for biomass trading ($30 billion), for biorefining inputs ($10 billion), for biorefining fuels ($80 billion), for bioplastics ($6 Read More >

Raining on Cellulosic Ethanol’s Parade

Writer Alyssa Danigelis posted an item of interest on Discovery News last month detailing the latest supposed “blow” to the biofuel industry. The writer highlights a new study in Agronomy Journal in which Kansas State University Assistant Professor Humberto Blanco-Canqui concludes, “Only a small fraction (about 25%) of residue might be available for removal, depending on soil type and climate. This small amount of crop residues is not economically feasible nor logistically possible.” Matt Merritt Read More >

Industrial and Environmental Biotech Weekly Blog Roundup

In industrial biotechnology this week the Wall Street Cheat Sheet says algae is the next great thing. “Algae could be the most promising candidate yet for the future of the biofuels industry. Although algae-based fuels won’t be commercially available for several years, algae offers several advantages over other first-generation renewable fuels, such as corn and soybeans. For example, algae grows faster, requires less resources, can be used as jet fuel, can use existing distribution systems, Read More >

Wrong Question: Can Biofuels Be Carbon Friendly?

The Science Insider blog last week hosted an interesting debate between Tim Searchinger, Princeton visiting scholar, and John Sheehan, of the Institute on the Environment at the University of Minnesota, regarding the recent policy proposal in the pages of Science by Searchinger et al. to “fix” the carbon accounting of biomass for bioenergy and biofuels in U.S. legislation and the successor to the Kyoto protocol, by giving credit only to biomass that can be managed Read More >

Compounded Climate Accounting Errors

Timothy Searchinger, visiting scholar at Princeton University, Dan Kammen of the University of California Berkeley, David Tilman of the University of Minnesota and other authors from the Environmental Defense Fund published an interesting new proposal in the Policy Forum section of Science magazine today. The argument put forward is that “Replacing fossil fuels with bioenergy does not by itself reduce carbon emissions, because the CO2 released by tailpipes and smokestacks is roughly the same per Read More >
