Testing shows UPM BioVerno renewable diesel reduces harmful tailpipe emissions
September 24, 2015
Testing, which is still ongoing, is showing that Finnish wood-based UPM BioVerno diesel (earlier post) significantly reduces harmful tailpipe emissions. A number of engine and vehicle tests have been carried out across a number of research institutes such as VTT Technical Research Center of Finland Lt;, University of Vaasa in Finland; and at FEV.
UPM BioVerno renewable diesel has already been shown to function just like conventional diesel in all diesel engines, while generating up to 80% fewer greenhouse gas emissions during its lifecycle compared to conventional fossil diesel fuels. The latest test results show that UPM BioVerno also reduces harmful tailpipe emissions.
Lux: Despite softness in utilization, global biofuels capacity to grow to 61.4 BGY in 2018; driven by novel fuels and feedstocks
August 31, 2015
The global biofuels industry averaged 68% in utilization rate from 2005 to 2014, reached a high of 80.9% in 2007, dropped to a low of 56.9% in 2012, and climbed slightly back to 60.4% in 2014. Despite the still apparent softness in capacity utilization, and the on-going softness in fossil fuel prices, global biofuels capacity will continue to grow from 55.1 billion gallons per year (BGY) to 61.4 BGY in 2018, according to a forecast by Lux Research. However, Lux predicts, growth between now and 2018 will not be a continuation of current course.
While ethanol and biodiesel will continue to dominate in absolute terms, these will grow at only a 1.5% CAGR through 2018. Novel fuels and feedstocks will drive the biofuels industry forward at a much more rapid 17% and 22% CAGRs through 2018, respectively.
Researchers propose 2nd law of thermodynamics-based process to select and develop microorganisms for optimal biofuel production
August 17, 2015
Researchers at the University of Maryland are proposing a new process to isolate and to direct the evolution of microorganisms that convert cellulosic biomass or gaseous CO2 and H2 to biofuels such as ethanol, 1-butanol, butane, or hexane (among others).
The approach is based on the theory that fermentation systems drive toward thermodynamic equilibrium. Physical chemists, observe Richard Kohn and Seon-Woo Kim, both of the Department of Animal and Avian Sciences, in their paper published in the Journal of Theoretical Biology, have understood that all chemical reactions are controlled by either thermodynamic or kinetic mechanisms. With thermodynamic control, the feasibility of reactions and the availability of pathway branches depend on the second law of thermodynamics. This law governs whether or not a reaction can proceed spontaneously in the forward direction based on the concentrations of reactants and products.
U Georgia team discovers tungsten in novel bacterial enzyme; potential for cellulosic biofuels
August 16, 2015
A team at the University of Georgia, Athens led by Distinguished Research Professor Michael Adams has discovered tungsten in what appears to be a novel enzyme in the biomass-degrading thermophilic bacterium Caldicellulosiruptor bescii. Tungsten is exceptionally rare in biological systems.
The researchers hypothesized that this new tungstoenzyme plays a key role in C. bescii’s primary metabolism, and its ability to convert plant biomass to simple fermentable sugars. This discovery could ultimately lead to commercially viable conversion of cellulosic biomass to fuels and chemical feedstocks. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Argonne researchers developing multifunctional farm landscapes balancing economy, bioenergy and environment
July 08, 2015
In collaboration with the farming community of the Indian Creek Watershed in central Illinois, researchers from Argonne National Laboratory (ANL) are finding ways to meet three agrarian land management objectives simultaneously: maximizing a farmer’s production; growing feedstock for bioenergy; and protecting the environment.
Through careful data collection and modeling at a cornfield in Fairbury, the Argonne team found that achieving these goals—which might under some conditions be mutually exclusive—requires a multifunctional landscape. Such a landscape is one where resources are allocated efficiently and crops are situated in their ideal soil and landscape position. As an example, planting bioenergy crops such as willows or switchgrass in rows where commodity crops are having difficulty growing could both provide biomass feedstock and also limit the runoff of nitrogen fertilizer into waterways—all without hurting a farmer’s profits.
BioMim project seeks to mimic chemistry of brown rot fungus to improve biorefining
July 07, 2015
BioMim, a newly-launched $4 million, four-year project funded by the Research Council of Norway with industrial partners Borregaard and Kebony, is seeking to mimic the chemistry of the brown rot fungus to improve biorefining processes. Specifically, the international team of researchers will seek to utilize the brown-rot fungi’s unique mechanisms to remove biomass components in cell walls, creating much improved access for an optimized enzyme system.
The BioMim project is combining two processes. The first is a technology developed by Virginia Tech Professor Barry Goodell that borrows from the processes used by brown rot fungi that are commonly found breaking down woody debris on the forest floor. The resulting catalytic process for freeing cellulose from lignin has now been demonstrated at pilot scale. The BioMim team will expand on this technology and explore how it can be used efficiently in large-scale biorefineries.

The BIOjet Abu Dhabi: Flight Path to Sustainability report outlines a set of recommended industry actions to create a commercially viable domestic aviation biofuel industry—a first for the Middle East. (Earlier post, earlier post.)
The BIOjet Abu Dhabi roadmap is the culmination of a year-long dialogue between Etihad Airways, its four BIOjet Abu Dhabi partners, and UAE and global stakeholders. It explains Abu Dhabi’s potential to produce aviation biofuel locally, in a sustainable way, taking account of all elements of the supply chain from feedstock supplies to biorefining and distribution.
EBI ketone condensation process for drop-in jet fuel or lubricant base oil from biomass; up to 80% lifecycle GHG savings
June 16, 2015
Researchers at the Energy Biosciences Institute (EBI), a partnership led by the University of California (UC) Berkeley that includes Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of Illinois at Urbana-Champaign, and BP, have developed a new method for producing drop-in aviation fuel as well as automotive lubricant base oils from sugarcane biomass. The strategy behind the process could also be applied to biomass from other non-food plants and agricultural waste that are fermented by genetically engineered microbes, the researchers said.
The catalytic process, described in an open-access paper in the Proceedings of the National Academy of Sciences (PNAS), selectively upgrades alkyl methyl ketones derived from sugarcane biomass into trimer condensates with better than 95% yields. These condensates are then hydro-deoxygenated into a new class of cycloalkane compounds that contain a cyclohexane ring and a quaternary carbon atom. These cycloalkane compounds can be tailored for the production of either jet fuel, or automotive lubricant base oils, resulting in products with superior cold-flow properties, density and viscosity that could achieve net life-cycle greenhouse gas savings of up to 80%, depending upon the optimization conditions.
Report for the EC evaluates prospects for sugar-based platforms for biofuels and biochemicals
May 08, 2015
A comprehensive review of 94 potential pathways to biofuels and biochemicals via the sugar platform, prepared for the European Commission (DG ENER) by a team from E4tech, RE-CORD and Wageningen UR, finds that the global market value of the sugar platform is today of the order of $65 billion, with bioethanol (from sugar and starch crops) by far the dominant product in the market.
While several newer biofuel and biochemical routes show significant growth potential, only a few are currently crossing the valley of death between research and commercialization. Of ten case studies (the technologies being at least at TRL5) considered in detail, most can deliver significant greenhouse gas (GHG) savings and identical (or improved) physical properties, but at an added cost to fossil alternatives.
BIO: RFS policy instability has chilled advanced and cellulosic biofuel investments; $13.7B shortfall
May 04, 2015
EPA’s delays in rulemaking for the Renewable Fuel Standard (RFS) over the past two years have chilled necessary investment in advanced and cellulosic biofuels just as they reached commercial deployment. The industry has experienced an estimated $13.7-billion shortfall in investment as a result, according to a new analysis released by the Biotechnology Industry Organization (BIO).
To reach the 2015 RFS goal of producing 5.5 billion gallons of advanced biofuels (including 3 billion gallons of cellulosic and 2.5 billion gallons of advanced biofuel or biodiesel), Bio Economic Research Associates (bio-era) estimated the need for 110 operating plants requiring $20.34 billion dollars in cumulative investment. The research and advisory firm also estimated that more than $95 billion in cumulative capital investments would be needed by 2022 for construction of nearly 400 advanced biofuel biorefineries with the capacity to produce 23 billion gallons of advanced biofuel.
Battelle passes 1,000-hour milestone with continuous hydrotreatment process for bio-oil to fuels
April 27, 2015
Researchers at Battelle led by principal investigator Dr. Zia Abdullah have demonstrated the durability of a continuous hydrotreatment process that converts bio-oil from biomass pyrolysis into transportation and aviation fuels, meeting the longevity goals of a challenge from the United States Department of Energy’s (DOE) to make commercially viable transportation fuels from biomass pyrolysis.
Battelle, with its proprietary process (earlier post) and catalyst from Pacific Northwest National Laboratory (PNNL) successfully registered more than 1,200 hours of operation of the system. The end hydrocarbon products are 30% blendable with ASTM petroleum fuels. The Battelle team has set its sights on achieving the near-commercial standard of 4,000 hours in the near future; 4,000 hours represents about half a year of continuous operation, Abdullah noted.
Indian researchers propose fuel-chemicals-electricity cellulosic biomass biorefinery scheme
April 19, 2015
Researchers from the CSIR-Indian Institute of Petroleum are proposing a biorefinery scheme using lignocellulosic biomass feedstock (sugarcane bagasse) for the production of fuel (ethanol), chemicals (furfural), and energy (electricity). The proposed scheme could be integrated with existing sugar or paper mills, where the availability of biomass feedstock is in abundance as a means to address some of the cost and logistics issues, they suggest in their paper published in the ACS journal Energy & Fuels.
In their approach, they extract fermentable sugar components (xylose and glucose) from sugarcane bagasse employing acid hydrolysis and enzymatic saccharification; recovery and reuse of the enzyme is a process advantage. The pentose fraction is used for yeast biomass generation and furfural production. High-temperature fermentation of the hexose stream by the thermophilic yeast Kluyveromyces sp. IIPE453 with cell recycle produces ethanol with an overall yield of 88% ± 0.05% and a productivity of 0.76 ± 0.02 g/L h−1. A complete material balance on two consecutive process cycles, each starting with 1 kg of feedstock, resulted in an overall yield of 366 mL of ethanol, 149 g of furfural, and 0.30 kW of electricity.

New version of Argonne lifecycle model for water footprint of biofuels now includes cellulosic feedstocks
January 16, 2015
Argonne National Laboratory released the newest version (3.0) of the online tool Water Assessment for Transportation Energy Resources (WATER) this week. This latest version of WATER allows, for the first time, biofuels manufacturers to analyze water consumption associated with use of cellulosic feedstocks such as residue left from lumber production and other wood-based resources. The new tool also provides analysis down to the county level in the US for the first time.
WATER adopts a water footprint methodology, and contains extensive climate, land use, water resource, and process water data. Version 3.0 of WATER thus can help biofuels developers gain a detailed understanding of water consumption of various types of feedstocks, aiding development of sustainable fuels that will reduce impact on limited water resources.

U Wisc. scientists develop new method to convert lignin to simple chemicals under mild conditions
November 03, 2014
Researchers at the University of Wisconsin have disclosed a new method to convert lignin, an important component of biomass waste, into simple chemicals. Lignin, which accounts for nearly 30% of the organic carbon in the biosphere, is a complex material containing chains of six-carbon rings. These aromatics could be the basis for a sustainable supply of useful chemicals, but only if the chains of lignin can be broken down into the individual units. Lignin, however, is highly resistant to breakdown, especially in a cost-effective way.
Prof. Shannon Stahl and his colleagues developed, in work funded by the Great Lakes Bioenergy Research Center at UW-Madison, a method for the depolymerization of oxidized lignin under mild conditions in aqueous formic acid that results in more than 60 wt% yield of low-molecular-mass aromatics. A paper on the method is published in the journal Nature.
