2016 Billion Ton Report shows US could sustainably produce at least 1B tons biomass by 2040 for bioeconomy
July 13, 2016
Within 25 years, the United States could produce enough biomass to support a bioeconomy, including renewable aquatic and terrestrial biomass resources that could be used for energy and to develop products for economic, environmental, social, and national security benefits, according to the new 2016 Billion-Ton Report, jointly released by the US Department of Energy and Oak Ridge National Laboratory (ORNL).
The 2016 Billion-Ton Report, volume 1, updates and expands upon analysis in the 2011 US Billion-Ton Update (earlier post), which was preceded by the 2005 US Billion Ton Study (earlier post). The report uses scientific modeling systems to project biomass resource availability under specified economic and sustainability constraints.
DOE issues RFI on biomass supply systems to support billion-ton bioeconomy vision
June 09, 2016
The US Department of Energy (DOE) has issed a Request for Information (RFI) (DE-FOA-0001603) seeking feedback from industry, academia, research laboratories, government agencies, and other stakeholders to support a “billion-ton bioeconomy.” This request for information (RFI) asks for input about specific aspects in the development of large-scale supply systems and technologies to eventually supply up to a billion dry tons of biomass feedstocks annually for a variety of end uses.
In 2005, a joint study by the US Departments of Agriculture and Energy (USDA and DOE) concluded that the land resources of the US could produce a sustainable supply of biomass sufficient to displace 30% or more of the country’s then-present petroleum consumption. The study found that just forest land and agricultural land alone have a potential for 1.3 billion dry tons of biomass feedstock per year—leading to the shorthand “billion-ton bioeconomy.” (Earlier post.)
New 3-step process for conversion of kraft lignin from black liquor into green diesel
June 01, 2016
Researchers in Sweden and Spain have devised a three-step process for the conversion of precipitated kraft lignin from black liquor into green diesel. Their paper appears in the journal ChemSusChem.
The kraft process converts wood into wood pulp for paper production. The process produces a toxic byproduct referred to as black liquor—a primarily liquid mixture of pulping residues (such as lignin and hemicellulose) and inorganic chemicals from the Kraft process (sodium hydroxide and sodium sulfide, for example). For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor or about 1.5 tons of black liquor dry solids.

Plans for facilities that use cellulosic biomass, algal biomass, or biosolids feedstocks will be considered under this funding opportunity.
ORNL team develops better moldable thermoplastic by using lignin; 50% renewable content
March 23, 2016
Researchers at Oak Ridge National Laboratory (ORNL) have developed a new class of high-performance thermoplastic elastomers for cars and other consumer products by replacing the styrene in ABS (acrylonitrile, butadiene and styrene) with lignin, a brittle, rigid polymer that, with cellulose, forms the woody cell walls of plants.
In doing so, they have invented a solvent-free production process that interconnects equal parts of nanoscale lignin dispersed in a synthetic rubber matrix to produce a meltable, moldable, ductile material that’s at least ten times tougher than ABS. The resulting thermoplastic—called ABL for acrylonitrile, butadiene, lignin—is recyclable, as it can be melted three times and still perform well. The results, published in the journal Advanced Functional Materials, may bring cleaner, cheaper raw materials to diverse manufacturers.
Double catalyst for the direct conversion of syngas to lower olefins
March 21, 2016
The light olefins ethylene, propylene, and butylene—usually made from petroleum—are key building blocks for chemical industry, and are starting materials for making plastics, synthetic fibers, and coatings. In the journal Angewandte Chemie, Chinese scientists report on a new bifunctional catalyst that converts syngas to lower olefins (C2-C4) with high selectivity. This could make it more attractive to make olefins from alternative sources of carbon, such as biomass, natural gas, or coal.
The design of bifunctional catalysts could result in further breakthroughs in developing one-step processes for selective production of fuels and chemicals such as gasoline, diesel, and aromatics from synthesis gas.

BETO is seeking information on all IBR processes and technologies, including any and all systems processes, technologies, methods and equipment employed to convert woody biomass, agricultural residues, dedicated energy crops, algae, municipal solid waste (MSW), sludge from wastewater treatment plants, and wet solids, into biofuels, biochemicals, and bioproducts.
Government of Alberta awarding $10M to SBI Bioenergy for production of drop-in hydrocarbon fuels; funds from carbon levy
March 10, 2016
Using revenue from the price Alberta’s large emitters pay for releasing greenhouse gases, the Climate Change and Emissions Management Corporation (CCEMC) has earmarked a $10-million contribution for Alberta-based SBI BioEnergy to support a $20-million facility for the demonstration-scale production of drop-in, renewable diesel, jet and gasoline fuels from plant oils and waste fats.
With this investment, SBI will be able to produce 10 million liters (2.6 million gallons US) of renewable diesel fuel annually. This support works in concert with Alberta’s Renewable Fuels Standard which requires commercial fuel producers to blend renewable products into their fuels. SBI’s facility strengthens Alberta’s expanding industrial bio-product sector and gives Alberta farmers a new market for off-grade canola.
Tohoku researchers develop efficient hydrodynamic reactor for pretreatment of biomass
March 07, 2016
Researchers at Tohoku University in Japan have developed a new system combining hydrodynamic cavitation with sodium percarbonate (SP) (an environmentally benign oxidation reagent) for the efficient pre-treatment of biomass. Compared to a pretreatment system using ultrasonication and SP (US-SP), the new HD-SP system was more efficient for glucose and xylose production; both systems resulted in a similar degree of lignin removal, and neither generated the inhibitor furfural, while it was detected in dilute acid (DA)-pretreated biomass.
In a paper published in the ACS journal Industrial & Engineering Chemistry Research, the Tohoku team sugested that the HD-SP system could be easily scaled up for a high-throughput system. Because compared to an US cavitation reactor it requires much lower energy input, it is promising for the industrial-scale pretreatment of lignocellulosic biomass, they said.
New ammonia biomass pretreatment process improves yield with lower enzyme loading; improving cellulosic biofuel economics
February 23, 2016
A team from the US, China and India, led by researchers from Michigan State University, has developed a new liquid ammonia biomass pretreatment methodology called Extractive Ammonia (EA). EA-pretreated corn stover delivers a higher fermentable sugar yield compared to the older Ammonia Fiber Expansion (AFEX) process while using 60% lower enzyme loading.
As described in a paper in the RSC journal Energy & Environmental Science, the single-stage EA process achieves high biofuel yields (18.2 kg ethanol per 100 kg untreated corn stover, dry weight basis), comparable to those achieved using ionic liquid pretreatments. The EA process achieves these ethanol yields at industrially-relevant conditions using low enzyme loading (7.5 mg protein per g glucan) and high solids loading (8% glucan, w/v).

UCLA–UC Berkeley paper outlines how CA can boost biofuel production to cut pollution and help the economy
December 07, 2015
California has not taken full advantage of opportunities to increase its in-state production of biofuel, despite state policies that encourage biofuel consumption, according to a policy paper by the Climate Change and Business Research Initiative at the UCLA and UC Berkeley law schools. The paper is the sixteenth in a series of reports on how climate change will create opportunities for specific sectors of the business community and how policy-makers can facilitate those opportunities.
The report—titled Planting Fuels: How California Can Boost Local, Low-Carbon Biofuel Production—underscores the importance of local production of low-carbon biofuel, suggesting that the state could reduce emissions by not shipping feedstocks from out-of-state or overseas; spurring development of carbon-reducing byproducts such as biochar compost; and reducing the risk of wildfire.

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.
