Sugar-derived levulinic esters and cyclic ether show superior anti-knock quality to Euro95 reference gasoline

April 24, 2017

A team from The Netherlands and the US reports that the sugar-derived levulinic esters methyl levulinate (ML) and ethyl levulinate (EL) and the sugar-derived cyclic ether (furfuryl ethyl ether (FEE) demonstrate superior anti-knock quality (in 10% blends) to a reference Euro95 gasoline.

The sugar-derived ethyl tetrahydrofurfuryl ether (ETE), another cyclic ether, conversely, performed markedly worse than the reference fuel on both setups. ETE this may be a more appropriate fuel additive for compression ignition engines, the authors suggest in an open-access paper published in the journal Fuel.

U Minn researchers develop bio-based elastomers from recoverable methyl valerolactone; tires, gaskets, seals, etc.

April 18, 2017

Researchers at the University of Minnesota have developed and demonstrated at laboratory scale a novel process to synthesize low-cost, polymeric valerolactones with tunable mechanical properties and low glass transition temperatures.

The glass transition temperature is the temperature region in which a polymer transitions from a hard, glassy material to a soft, rubbery material. In other words, when the polymer is cooled below the glass transition temperature, it becomes hard and brittle. The low glass transition temperature allows these polymers to be used at lower temperatures than other biodegradable polymers; applications could include tires, gaskets, seals adhesive, sealant and damping products.

DOE BETO report provides overview of current state of alternative aviation fuels; overcoming technical and commercial barriers

March 29, 2017

The US Department of Energy’s Bioenergy Technologies Office (BETO) has published a report titled Alternative Aviation Fuels: Overview of Challenges, Opportunities, and Next Steps. The report provides an overview of the current state of alternative aviation fuels, as reported in findings by recent working groups, and also presents findings from the Alternative Aviation Fuel Workshop hosted by BETO in September 2016.

Unlike other liquid fuels (e.g., diesel or gasoline) with developed alternatives (such as electrical power), alternatives to current aviation jet fuels are at the early stages of development. In the near term, the most promising option is bio-derived aviation fuel. Bio-based jet fuels also present a tremendous opportunity to transition away from fossil fuels towards domestically produced aviation biofuel that would further reduce US reliance on foreign oil and create jobs, BETO notes.

Aachen team develops framework for model-based formulation of biofuel blends with tailored properties

March 28, 2017

A team at RWTH Aachen University has developed a framework for the model-based formulation of biofuel blends with tailored properties by considering the fuel’s molecular composition as the fundamental design degree of freedom. A paper on their work is published in the ACS journal Energy & Fuels.

The researchers envision that the model-based approach can (i) guide fundamental experimental investigations of the combustion behavior of blended biofuels toward the most favorable mixtures and (ii) identify promising conversion pathways for further elaboration by means of reaction engineering and conceptual process design. The latter is ultimately needed to bridge the gap from a mass- and energy-based molecular level analysis to a process level analysis addressing the economics of the involved conversion and separation steps.

Lux Research forecasts global biofuels output to rise to 67B GPY in 2022; advanced biofuels will nearly double to 9.6B GPY

February 14, 2017

New biofuel technology is finally starting to push aside traditional biofuels such as first-generation biodiesel, according to a new report by Lux Research. New facilities based on non-food feedstocks and producing novel fuels account for over half of new capacity deployment for the first time in the biofuel industry’s history, according to Lux. However, overall output will grow at a slower pace to 67 billion gallons a year (BGY) in 2022, from 59 BGY in 2016.

The report, titled “Biofuels Outlook 2022: The Dawn of a New Era in Global Biofuel Capacity Expansion,” is part of the Lux Research Alternative Fuels Intelligence service. Lux Research analysts quantified the commercial deployment of new technologies in the global biofuels industry using a database of nearly 2,000 facilities from 1,461 companies in 90 countries with nameplate capacity data through 2022.

Researchers find shade from stand density can cost farmers about 10% of potential crop yield

January 30, 2017

A team from the University of Illinois has found that compared to top leaves, the shaded lower level leaves of C4 crops planted in dense stands such as corn and Miscanthus underperform, costing farmers about 10% of potential yield.

These findings, published in an open-access paper in the Journal of Experimental Botany, could help scientists further boost the yields of corn and Miscanthus, as well as other C4 crops that have evolved to photosynthesize more efficiently than C3 plants such as wheat and rice.

US DOD to award $55M for advanced drop-in biofuels production; 10M gallons/year

January 25, 2017

The US Air Force Research Laboratory, Materials and Manufacturing Directorate (AFRL/RX) has issued a funding opportunity (FOA-RQKM-2017-0006) for up to $55 million to design, retrofit, construct, operate, validate and qualify domestic, commercial-scale, an integrated biorefinery(s) capable of producing bio-equivalent fuels suitable for military use with a rated capacity of at least 10 million gallons of neat biofuel per year. Cost competitiveness of the neat biofuel fraction with conventional petroleum-derived fuels is a primary goal.

The biorefinery—which may be either a brownfield expansion/modification of existing facilities, or new greenfield construction—is required to use domestic feedstock, and create an Integrated Biofuels Production Enterprise (IBPE). Expansions must add an additional 10 million gpy of capacity; new construction must support the 10 million gpy capacity.

DOE Co-Optima initiative publishes report reviewing first 12 months; progress on fuels and engines

January 16, 2017

The US Department of Energy’s (DOE’s) Co-Optima initiative—a broad, joint effort to co-optimize the development of efficient engines and low greenhouse-gas fuels for on-road vehicles with the goal of reducing petroleum consumption by 30% by 2030 beyond what is already targeted (earlier post)—has published a year-in-review report for FY 2016—the initiative’s first 12 months.

Co-Optima’s premise is that current fuels constrain engine design—and thus engine efficiency. The researchers suggest that there are engine architectures that can provide higher thermodynamic efficiencies than available from modern internal combustion engines; however, new fuels are required to maximize efficiency and operability across a wide speed/load range. The report details the technical progress in a selection of projects across the initiative’s two main thrusts: spark ignition (SI) and advanced compression ignition (ACI).

Researchers in China develop new process for direct synthesis of drop-in jet-fuel-range blendstock from lignocellulose

December 29, 2016

Researchers in China have developed an integrated two-bed continuous flow reactor process for the direct synthesis with high carbon yields (~70%) of dodecanol (C12H26O) or 2,4,8- trimethylnonane (C12H26O2)—a jet-fuel-range C12 branched alkane—from methyl isobutyl ketone (MIBK), which can be derived from lignocellulose.

The dodecanol as obtained can be used as the feedstocks in the production of sodium dodecylsulphate (SDS) and sodium dodecyl benzene sulfonate (SDBS)—widely used as surfactants or detergents. The 2,4,8-trimethylnonane as obtained can be blended into conventional jet fuel without hydroisomerization. A paper on their work is published in the journal ChemSusChem.

ARPA-E to award $25M for macroalgae projects; seaweed biomass to be cost-competitive with terrestrial biomass at energy-relevant scales

December 16, 2016

ARPA-E announced up to $25 million in funding for the MacroAlgae Research Inspiring Novel Energy Resources (MARINER) program (DE-FOA-0001726). The program will focus on developing advanced cultivation technologies that enable the cost and energy efficient production of macroalgal biomass in the ocean at a scale suitable as feedstock for the production of fuels and chemicals. The deadline to submit a Concept Paper for MARINER is 5 pm ET, 14 February 2017.

The US has the world’s largest marine Exclusive Economic Zone—an area of ocean along the nation’s coast lines which is equivalent to the total land area of all 50 states. The US has the potential to utilize this resource to build and grow a thriving marine biomass industry for the production of fuels, chemicals, feed, and food. Growing macroalgal biomass in the oceans offers a unique opportunity to sidestep many of the challenges associated with terrestrial biomass production systems, particularly the growing competition for land and freshwater resources, which are likely to result from the 50 to 100% increase in demand for food expected for 2050.

LANL team develops simple catalyst system to upgrade acetone to range of chemicals and fuels

December 12, 2016

Researchers at Los Alamos National Laboratory (LANL) have developed a simple inexpensive catalyst system (Amberlyst 15 and Ni/SiO2–Al2O3) to upgrade bio-derived acetone to provide C6, C9, and C12 aliphatic ketones, along with C9, C12, and C15 aromatic compounds. Stepwise hydrodeoxygenation of the produced ketones can yield branched alcohols, alkenes, and alkanes. A paper on their work is published in the journal ChemSusChem.

Predicted and measured fuel properties of a selection of these produced molecules showed that certain compounds are candidates as drop-in fuel replacements for spark- and compression-ignition engines.

WSU Tri-Cities researchers receive $50K NSF grant to test market potential for lignin pathway for biojet

December 03, 2016

Researchers at Washington State University Tri-Cities have been awarded a $50,000 National Science Foundation I-Corps grant to explore the commercialization potential of their new pathway for biojet from biomass waste. The WSU process, described in a 2015 paper in the RSC journal Green Chemistry, uses hydrodeoxygenation (HDO) of dilute alkali extracted corn stover lignin catalyzed by a noble metal catalyst (Ru/Al2O3) and acidic zeolite (H+-Y) to produce lignin-substructure-based hydrocarbons (C7-C18), primarily C12-C18 cyclic structure hydrocarbons in the jet fuel range. (Earlier post.)

Current biorefineries undervalue lignin’s potential, largely because selective conversion of lignin has proven to be challenging. Processes that have been successful at breaking the lignin bonds have typically resulted in shorter chain monomers as opposed to the longer chain hydrocarbons needed for fuel. In contrast, the output of the WSU processis a mix of hydrocarbons that are long-chain and can be made into nearly the right mix for jet fuel.

GAO study concludes Renewable Fuel Standard will miss advanced biofuel program targets; EPA generally concurs

November 29, 2016

A new study from the US Government Accountability Office (GAO) concludes that the Renewable Fuel Standard program will miss its advanced biofuel targets due to the the high costs of creating advanced biofuel; the relatively low price of fossil fuel; the timing and cost to bring new tech to commercial-scale production; regulatory uncertainty; and other issues as challenges to increased production.

GAO was asked by Congress to review issues related to advanced biofuels R&D. The report describes (1) how the federal government has supported advanced biofuels R&D in recent years and where its efforts have been targeted; and (2) expert views on the extent to which advanced biofuels are technologically understood and the factors that will affect the speed and volume of production. GAO interviewed DOD, DOE, EPA, NSF, and USDA officials and worked with the National Academy of Sciences to convene a meeting of experts from industry, academia, and research organizations. EPA generally agreed with the conclusions of the report, the GAO said.

UW-Madison and GLBRC team engineers S. cerevisiae to ferment xylose, nearly doubling efficiency of converting biomass sugars to biofuel

Scientists at the University of Wisconsin­-Madison and the Great Lakes Bioenergy Research Center (GLBRC) have used directed evolution to nearly double the efficiency with which the commonly used industrial yeast Saccharomyces cerevisiae converts plant sugars to biofuel. The resulting improved yeast could boost the economics of making ethanol, specialty biofuels and bioproducts.

S. cerevisiae poses a challenge to researchers using it to make biofuel from cellulosic biomass such as grasses, woods, or the nonfood portion of plants. Although the microbe is highly adept at converting a plant’s glucose to biofuel, it ignores the plant’s xylose, a five-carbon sugar that can make up nearly half of all available biomass sugars.

NREL and partners build pilot plant to co-process biomass streams with petroleum

October 14, 2016

The National Renewable Energy Laboratory (NREL), together with leading petroleum refining technologies supplier W.R. Grace, and leading pilot plant designer Zeton Inc., built a unique pilot-scale facility that can produce biomass-derived fuel intermediates with existing petroleum refinery infrastructure. This pilot plant, constructed in part with funding from the Bioenergy Technologies Office, combines biomass pyrolysis together with fluid catalytic cracking—one of the most important conversion processes used in petroleum refineries—to demonstrate the potential to co-process biomass-derived streams with petroleum, at an industrially-relevant pilot scale.

There are 110 domestic fluid catalytic cracking units currently operating in the United States. Using them to co-produce biofuel could enable production of more than 8 billion gallons of bio-derived fuels, without construction of separate biorefineries. This would significantly contribute to the Renewable Fuel Standard mandate set by the Energy Independence and Security Act of 2007 to produce 21 billion gallons of advanced renewable transportation fuels by 2022.

China researchers devise process to convert biomass to gasoline via one-step DME synthesis: DTG

October 10, 2016

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology have proposed a new process for the conversion of biomass to gasoline via a one-step DME synthesis (DTG: Dimethyl ether to gasoline). In a paper in the journal Fuel, they report a per-pass conversion of CO and the production capacity of gasoline of up to 45% and 4.4 kg/h, respectively.

Their homemade catalysts exhibited favorable activity, selectivity and stability during all the operations. The gasoline obtained from the pilot plant had a high octane number (RON>93). Although further studies are needed on mass and energy balances to ensure the most economical and optimal heat integration strategy, the practical experience of this work is sufficiently promising to merit further investigations, the team suggested.

Researchers show mixotrophic fermentation process improves carbon conversion, boosting yields and reducing CO2

October 03, 2016

A team from White Dog Labs, a startup commercializing a mixotrophy-based fermentation process, and the University of Delaware have shown that anaerobic, non-photosynthetic mixotrophy—the concurrent utilization of organic (for example, sugars) and inorganic (CO2) substrates in a single organism—can overcome the loss of carbon to CO2 during fermentation to increase product yields and reduce overall CO2 emissions.

In an open-access paper published in Nature Communications, the researchers report on their engineering of the bacterium Clostridium ljungdahlii to produce acetone with a mass yield 138% of the previous theoretical maximum using a high cell density continuous fermentation process. In addition, when enough reductant (i.e., H2) was provided, the fermentation emitted no CO2. They further showed that mixotrophy is a general trait among acetogens.

Global Bioenergies reports first production of isobutene from wheat straw at the industrial pilot scale

September 29, 2016

Global Bioenergies and Clariant announced the first isobutene production from a wheat straw hydrolysate, in the industrial pilot of Pomacle Bazancourt. This success is the result of a collaboration initiated more than 18 months ago, and has been made possible by combining Clariant’s proprietary process, allowing for the conversion of agricultural residues into sugar-rich hydrolysates, with Global Bioenergies’ proprietary process for the production of isobutene from various industrial-grade sugars.

Clariant has produced the wheat straw hydrolysate, rich in non food/non feed second generation sugar, in its Straubing facility in Germany. This hydrolysate was converted into renewable isobutene in Global Bioenergies’ industrial pilot operated by ARD in its Pomacle-Bazancourt facility. This result demonstrates the maturity, the complementarity, and the versatility of the two proprietary processes.

Study finds isopropanol-n-butanol-ethanol and gasoline blend viable as alternative fuel

September 05, 2016

Researchers from the University of Illinois and colleagues in China investigating the performance, combustion and emission characteristics of a port fuel-injection SI engine fueled with isopropanol-n-butanol-ethanol (IBE)-gasoline blends have concluded that an IBE30 blend could be a good alternative to gasoline.

Bio-n-butanol itself is a promising alternative fuel, produced conventionally from the fermentation of carbohydrates by Clostridium bacteria in a well-established process referred to as ABE fermentation, after its major chemical products: acetone, butanol and ethanol. However, ABE fermentation production suffers from relatively low production efficiency as well as the high cost of component recovery; the product mixture typically has an A:B:E ratio of 3:6:1.

China researchers develop new pathway for jet-range bio-cycloalkanes from acetone and hydrogen

August 12, 2016

Researchers from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, have developed a new route for the synthesis of jet-fuel range C10 and C12 cycloalkanes using diacetone alcohol (the self-aldol condensation product of acetone under mild conditions)—which can be derived from lignocellulosic biomass—and hydrogen. A paper on their work is published in the RSC journal Green Chemistry.

The branched cycloalkanes are synthesized with high carbon yield (~76%), have high density (0.83 g mL-1) and a low freezing point (216.5 K). As a potential application, they can be used as additives to conventional bio-jet fuel comprising C8-C16 chain alkanes.

Argonne team finds significant albedo warming effect for switchgrass ethanol

August 11, 2016

One of the key points of contention over the climate benefit of biofuels is the impact of land use change (LUC) associated with biofuel feedstock production. LUC results in biogeochemical (e.g., soil organic carbon) and biogeophysical (e.g., surface albedo, evapotranspiration, and surface roughness) changes. Of the biogeophysical factors, surface albedo has been considered a dominant effect at the global scale.

A team at Argonne National Laboratory has now quantified land use change (LUC)-induced albedo effects for three major biofuels in the US, using satellite data products for albedo and vegetation observations. Published in the RSC journal Energy & Environmental Science, the analysis indicates that the land use change (LUC)-induced albedo effect is small for corn and miscanthus ethanol, but is significant for switchgrass ethanol, which is driven by the types, locations, and intensities of various land conversions to these biofuel feedstocks.

Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

August 08, 2016

The US Renewable Fuel Standard (RFS2) is intended to reduce greenhouse gas emissions from transportation. However, argues a team from the University of Minnesota in an open-access paper published in the journal Energy Policy, once the “fuel market rebound effect” is factored in, RFS2 actually increases GHG emissions when all fuel GHG intensity targets specified under the act are met.

Increasing the supply of low-carbon alternative fuels is a basic strategy to reduce greenhouse gas emissions. However, the Minnesota team notes, increasing the supply of fuels tends to lower energy prices, which encourages in turn encourages additional fuel consumption. This “fuel market rebound effect” can undermine climate change mitigation strategies, even to the point where efforts to reduce GHG emissions by increasing the supply of low-carbon fuels may actually result in increased GHG emissions.

JBEI scientists use CO2 to control toxicity of ionic liquids in biomass pretreatment; lowering production costs

July 22, 2016

Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory and Sandia National Laboratories working at the Joint BioEnergy Institute (JBEI) have demonstrated that adding CO2 during the deconstruction phase of biofuel production successfully neutralizes the toxicity of ionic liquids, the room-temperature molten salt solvent used at JBEI to break down cellulosic plant material.

The process is easily reversible, allowing the liquid to be recycled for use as a solvent again. Their study, published RSC journal Energy & Environmental Science, addresses a significant obstacle to expanding the market for biofuels: lowering the cost of production.

UK team produces hydrogen from fescue grass via photocatalytic reforming

July 21, 2016

A team of researchers from the UK’s Cardiff University’s Cardiff Catalysis Institute and Queen’s University Belfast have shown that significant amounts of hydrogen can be unlocked from fescue grass—without significant pre-treatment—using sunlight and a metal-loaded titania photocatalyst. An open access paper on their work is published in Proceedings of the Royal Society A.

Based on their study, the team proposed that the first step in their photoreforming of cellulose was the (photo)hydrolysis of cellulose into glucose, with the latter then undergoing reforming to hydrogen and CO2. It is the first time that this method has been demonstrated and could potentially lead to a sustainable way of producing hydrogen.

Los Alamos team develops robust route to convert starch and sugar to C10 and C11 hydrocarbons; “potato-to-pump”

July 18, 2016

Researchers at Los Alamos National Laboratory have developed a route to convert oligosaccharides, such as starch, cellulose, and hemicelluloses to C10 and C11 hydrocarbons by using depolymerization followed by chain extension.

In a paper published in the journal ChemSusChem, they report on the robustness of the approach by performing a simple starch extraction from a Russet potato and subjecting it to their process. (They noted that the use of the potato was simply illustrative, and that the use of food crops for fuel production should be avoided.)

New hybrid sweetgum trees could boost paper, bioenergy production

Researchers at the University of Georgia (UGA) have crossed American sweetgums with their Chinese cousins, creating hybrid sweetgum trees that have a better growth rate and denser wood than natives, and can produce fiber year-round. The hybrid sweetgum trees have enormous potential for the production of bioenergy and paper, said Scott Merkle, a professor in UGA’s Warnell School of Forestry and Natural Resources.

Sweetgum trees thrive under diverse conditions, grow as fast as pine trees and provide the type of fiber needed for specialty papers-and they’ve long been desired by paper and bioenergy producers. However, harvesting mature sweetgums can often be too costly or even ill-advised because they typically grow the best on the edges of swamps and in river bottoms, which are often inaccessible during the wet winter months.

Navy study highlights potential of alkyl dioxolanes as fuel additives, importance of 2,3-BD as biomass-derived platform molecule

June 17, 2016

Researchers at the Naval Air Warfare Center Weapons Division (NAWCWD), China Lake have developed a solvent-free process for the conversion of 2,3-Butanediol (2,3-BD)—a renewable alcohol that can be prepared in high yield from biomass sugars—to a complex mixture of 2-ethyl-2,4,5-trimethyl-1,3-dioxolane (TMED) and 4,5-dimethyl-2-isopropyl dioxolane (DMID). They found that dioxolane mixture has potential applications as a sustainable gasoline blending component, diesel oxygenate, and industrial solvent (Earlier post.)

The promising results of the study, published in the journal ChemSusChem, suggest that TMED and other alkyl dioxolanes warrant further study as fuel additives, the researchers said. A wide variety of dioxolane molecules can be accessed by the reaction of renewable diols with ketones and aldehydes, allowing for custom tailoring of fuel and solvent properties. The study also suggests that—given its to be efficiently generated from a variety of biomass sources through fermentation—2,3-BD is an important platform molecule that should be exploited as a versatile intermediate to sustainable fuels and chemicals.

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.)

RIT and Synergy Biogas partner on algae for wastewater cleanup and biofuel production

June 03, 2016

Rochester Institute of Technology (RIT) and Synergy Biogas are exploring the environmental benefits of microalgae to clean agricultural wastewater and make biofuels. Jeff Lodge, associate professor in RIT’s Thomas Gosnell School of Life Sciences, is running a three-month pilot program at Synergy Biogas, a high-tech anaerobic digester located on Synergy Farms in Covington, N.Y, to grow microalgae on digested biomass. Microalgae will consume contaminants in wastewater and produce an algal biomass that Lodge will use as a feedstock for renewable energy.

Lodge will grow the microalgae in a 1,000-gallon tank at Synergy in a process that can be scaled up to treat 52,000 gallons, or 200,000 liters, of wastewater a day. The trial project will demonstrate the organisms’ ability to consume ammonia, phosphorous and nitrogen from digested biomass and reduce contaminants below state-mandated levels. Lodge’s laboratory experiments with microalgae have reduced phosphorous in wastewater by greater than 90% to levels of 0.1 parts per million, exceeding the required 1 parts per million in New York.

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.

China team directly synthesizes gasoline- and diesel-range alkanes from acetone from biomass

May 17, 2016

Researchers in China have directly synthesized gasoline- and diesel-range C6-C15 branched alkanes in high carbon yield (~80%) via the self-condensation of acetone and the subsequent hydrodeoxygenation over a dual-bed catalyst system. A paper on their work appears in the RSC journal Green Chemistry.

Acetone is a by-product in the production of bio-butanol via the acetone-butanol-ethanol (ABE) fermentation of lignocellulose. In a typical ABE fermentation, butanol, acetone and ethanol are produced at a weight ratio of 6:3:1.4 Acetone can also be produced by ketonization of acetic acid—a low-cost lignocellulosic platform compound which is obtained as a by-product in furfural production or from the fermentation of lignocellulose.
