If you can imagine a future powered by sustainable food and fuels; if you can imagine a future where globalism means that appropriate technologies are employed where they work best to the globes greatest advantage; if you can imagine a future of cooperation and collaboration to work out humankinds tensions, then you see a future envisioned by Advanced Biofuels USA.. The future of the advanced biofuels industry is at a critical crossroads. In the US, the Renewable Fuel Standard has created a demand of 15 billion gallons/year of corn ethanol, an amount which covers about 10% of the US market and provides renewable octane by replacing carcinogenic MTBE. US and Brazilian sources have filled this demand. However, the US seems stuck on the 15 billion/year plateau providing no meaningful demand for advanced motor vehicle biofuels. Even the Renewable Fuel Standard (RFS) has little impact since it has not been used by the government to push for more investment in advanced biofuels. Once corn ethanol ...

An item of interest to ethanol producers and other supporters of ethanol is this announcement by EPA, as further clarified by this announcement by EERE: The U.S. Environmental Protection Agency (EPA) announced on November 17 that the 2009 renewable fuel standard (RFS) will require most refiners, importers, and non-oxygenate blenders of gasoline to displace 10.21% of their gasoline with renewable fuels such as ethanol. That requirement aims to ensure that at least 11.1 billion gallons of fuels will be sold in 2009. . . . While the RFS requirement is increasing by about 23%-from 9 billion gallons in 2008 to 11.1 billion gallons in 2009-the percentage requirement is increasing by nearly one third, from 7.76% in 2008 to 10.21% in 2009. The larger relative increase in the percentage requirement reflects the fact that fuel consumption is expected to be lower in 2009, so a greater percentage of renewable fuel is needed to reach 11.1 billion gallons of renewable fuels. ....

Among various plant-derived biomass, starch and sugar crops are recognized as major feedstock for the first generation of biorefinery, whereas lignocellulosic biomass is regarded as the feedstock for the second generation. This chapter reviews primarily aspects of production, processing technology, and uses of industrial sugar and starch crops, as well as the future of these crops for biorefinery. The use of sugar crops (sugar cane, sugar beet, sweet sorghum) as the feedstock in biorefinery has a greater advantage in terms of crop reproduction and the conversion process over the starch crops. The major sources of starch crops for biorefinery include cereal grains (corn, wheat, and rice) and roots and tubers (potato and cassava). Either the use of sugar or starch crops individually can be achieved in biorefinery, but the integration of sugar- and starch-based biorefinery production can significantly improve the overall process economics and commercialization. ...
TY - BOOK. T1 - Process design, supply chain, economic and environmental analysis for chemical production in a glycerol biorefinery: Towards the sustainable design of biorefineries. AU - Loureiro da Costa Lira Gargalo, Carina. PY - 2017. Y1 - 2017. N2 - Drivers such as our deep dependence on fossil fuels availability and price volatility, global concern about climate change and social distress, are steering the economy to be more sustainable and based on a greater use of renewable resources. Therefore, the concept of integrated biorefineries has attracted much attention by aspiring at replacing fossil sources. However, as has been recently witnessed through multiple failures and the shutdown of biorefinery plants all over the world, a biobased economy that heavily depends on the production of biofuels, leads to unsatisfactory results. Thus, it seems that an economy based on the innovative and cost-efficient use of bio-resources for the production of both chemicals and biofuels/bioenergy, is in ...
Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. However, the biomass recalcitrance limits the microbial degradation as well as the biogas production from these types of materials. In the present work different pretreatment methods have been performed in order to decrease the biomass recalcitrance and improve the biogas production. Steam explosion pretreatment, together with the addition of sodium hydroxide and hydrogen peroxide, has been performed on lignocellulosic-rich paper tube residuals. The pretreatment has resulted in methane yields of up to 493 NmL/gVS, which is an increase by 107% compared with untreated material. Furthermore, the use of an organic solvent, N-methylmorpholine-N-oxide (NMMO), ...
Biobased and Renewable Products Advocacy Group (BRAG®). Overview:. Biobased chemicals and biofuels are steadily taking root thanks to both popular appeal and political support. The consumer and political goals of reducing Americas dependence on foreign oil, enhancing national security, and greening the economy converge in biobased chemicals and advanced biofuels, the promising technology of producing commercial chemicals and fuels from renewable resources. With Congresss commitment to advanced biofuels found in the 2007 Energy Independence and Security Act, compelling incentives to invest in and support growth of biotechnologies has spurred record production. Some estimate biobased chemicals share of the global chemical industry will grow from 2 percent to 22 percent by 2025.. Much of the growth in biofuels technology development has been driven by the fuel-blending requirements set in the U.S. Environmental Protection Agencys (EPA) Renewable Fuel Standard (RFS). But the RFS, along with ...
Fatty acid-derived biofuels can be a better solution than bioethanol to replace petroleum fuel, since they have similar energy content and combustion properties as current transportation fuels. The environmentally friendly microbial fermentation process has been used to synthesize advanced biofuels from renewable feedstock. Due to their robustness as well as the high tolerance to fermentation inhibitors and phage contamination, yeast strains such as Saccharomyces cerevisiae and Yarrowia lipolytica have attracted tremendous attention in recent studies regarding the production of fatty acid-derived biofuels, including fatty acids, fatty acid ethyl esters, fatty alcohols, and fatty alkanes. However, the native yeast strains cannot produce fatty acids and fatty acid-derived biofuels in large quantities. To this end, we have summarized recent publications in this review on metabolic engineering of yeast strains to improve the production of fatty acid-derived biofuels, identified the bottlenecks that ...
Towards Biodiesel Production Using Non-Lipid Biomass Biodiesel is technically defined as alkyl (usually methyl and ethyl) esters of long-chain fatty acids. When used as a fuel, biodiesel shows many merits, such as high energy density, more favorable combustion emission profile, improved lubricating properties, and others. It is also an environment-benign fuel comparing with petroleum-based diesel, as biodiesel is biodegradable, non-toxic, and essentially carbon dioxide neutral. Therefore, biodiesel is considered as an excellent renewable energy carrier. Biodiesel is now commercially manufactured through transesterification of lipids, or triacylglycerides (TAG) originated from plant seeds or animal tissues. Various renewable lipids were chosen as feedstock for biodiesel production. For example, European countries use rapeseed oil; USA, soybean oil; and the Southeast Asian countries, palm oil, etc. Current world TAG production with grassy oil crops or other woody oil plants produces around 120 ...

A complaint to the advertising watchdog by Guardian columnist and environmental campaigner George Monbiot has caused a national press ad claiming biofuels offer a sustainable alternative to oil to be banned.. The national press campaign, by the Renewable Fuels Association (RFA), was headed "OPEC rakes in billions, but blames biofuels - confused?". Copy in the ad formed an open letter to the president of OPEC, the oil producers cartel, from the "worlds biofuels industries." The open letter offered a defence against accusations that the presence of biofuels in the market has caused a 40% rise in oil prices.. "We are proud of our efforts to provide a lower priced, renewable fuel to the world today," stated the letter. It ended with the line "Biofuels - a lower priced, sustainable answer to OPECs oil.". Monbiot, who has previously argued against the idea of sustainable biofuels in the Guardian, lodged a complaint with the Advertising Standards Authority that the RFA claim in the press campaign ...
Generation of biofuels from sugars in lignocellulosic biomass is a promising alternative to liquid fossil fuels, but efficient and inexpensive bioprocessing configurations must be developed to make this technology commercially viable. One of the major barriers to commercialization is the recalcitrance of plant cell wall polysaccharides to enzymatic hydrolysis. Biomass pretreatment with ionic liquids (ILs) enables efficient saccharification of biomass, but residual ILs inhibit both saccharification and microbial fuel production, requiring extensive washing after IL pretreatment. Pretreatment itself can also produce biomass-derived inhibitory compounds that reduce microbial fuel production. Therefore, there are multiple points in the process from biomass to biofuel production that must be interrogated and optimized to maximize fuel production. Here, we report the development of an IL-tolerant cellulase cocktail by combining thermophilic bacterial glycoside hydrolases produced by a mixed consortia ...
Fireplaces are surely one of the most iconic parts of the chilling winter season. We have been using fireplaces to make our rooms cozy and warm during the winter season for a very long time.

Nigerias state oil corporation has signed a memorandum of understanding (MoU) with the Kebbi State Government (KBSG) to build a bioethanol plant.. The plant is expected to use cassava and sugarcane as a feedstock and produce 84 million litres of ethanol per year, the Nigerian National Petroleum Corporation (NNPC) said in a statement.. The Nigerian government is investing in biofuels as it reduces its dependence on oil and diversifies its economy.. The MoU was signed on 16 November, 2017. Speaking at the signing, Maikanti Baru said the project will involve the development of 20,000 hectares of an integrated plantation and plant complex.. Biofuels production. Baru said: "Let me use this opportunity to convey my sincere appreciation to the Government of Kebbi State on her interest to partner NNPC in achieving the Federal Governments mandate on automotive biofuels production in Nigeria.. "Today is a watershed in the life of Kebbi State prime position as the food basket and feeder of the nation. ...
In recent years, the development of alternative fuels from renewable resources, like biomass, has received considerable attention. Biodiesel is defined as fatty acid methyl or ethyl esters from vegetable oils, when it is used as fuel in diesel engines and heating systems. In this context, the use of used frying oil (UFO) as a raw material for biodiesel production has gained special interest since it has provided a potential added value to what has traditionally been treated as a residue. Methyl or ethyl esters are the product of transesterification of vegetable oils with alcohol (methanol/ethanol) using an alkaline catalyst. In addition, the process yields glycerol, which has large applications in the pharmaceutical, food and plastics industries. In the present work, the process of biodiesel production for pilot plant using sunflower oil as raw material with methanol and using potassium hydroxide as catalyst has been studied providing a mass and energy balance of the process. The biodiesel ...
ABSTRACT: Bioethanol (fuel ethanol derived through fermentation) is now the leading biofuel alternative to fossil-based liquid transportation fuels. Current production is dominated by U.S. corn-based and Brazilian sugarcane-based processes. However, more sustainable future bioethanol production needs to be based on non-food substrates that use lignocellulosic biowastes. The brewing and distilling industry sectors are uniquely placed to exploit the conversion of lignocellulose to bioethanol, through the utilization of spent grains. Bioconversion of brewers spent grains (BSG) to fuel alcohol represents an attractive but challenging opportunity for sustainable bioethanol production. In addition to the technological and scientific challenges in bioethanol production from spent grains, there are also constraints relating to economics and energy balances. For example, enzyme costs need to be lowered, particularly considering cellulolysis of feedstock. Any innovations to decrease cellulase enzyme ...
The advantages of newly developed high biomass sorghum and pearl millet developed by ICRISAT and Indian Institute of Millets Research (IIMR) for use as feedstock in second generation or lignocellulosic (2G) biofuel production in India was highlighted at a recent workshop.. The advantageous traits of these dryland crops are wider adaptability, fast growth, high biomass production potential, resilience to drought, and non-compromise on food security as the grain is used for human consumption. The use of these crops in biofuel production has the potential of improving incomes of Indian farmers in the semi-arid regions.. India is a signatory to the UN Climate Change Paris Agreement (COP21) and biofuel production is one of the thrust areas identified to reduce greenhouse gas emissions. The countrys ethanol production is mainly from sugarcane molasses. However, considering severe water shortages there is limited scope to increase the production of this water-intensive crop. Hence there is a need to ...

The feedstocks used for the production of bio-based chemicals have recently expanded from edible sugars to inedible and more recalcitrant forms of lignocellulosic biomass. To produce bio-based chemicals from renewable polysaccharides, several bioprocessing approaches have been developed and include separate hydrolysis and fermentation (SHF), simultaneous saccharification and fermentation (SSF), and consolidated bioprocessing (CBP). In the last decade, SHF, SSF, and CBP have been used to generate macromolecules and aliphatic and aromatic compounds that are capable of serving as sustainable, drop-in substitutes for petroleum-based chemicals. The present review focuses on recent progress in the bioprocessing of microbially produced chemicals from renewable feedstocks, including starch and lignocellulosic biomass. In particular, the technological feasibility of bio-based chemical production is discussed in terms of the feedstocks and different bioprocessing approaches, including the consolidation of enzyme
Professor Mathews said: "Branding all biofuels from developing countries as unsustainable and blocking exports of these fuels to developed nations is disguised protectionism.. "Agriculture in developing countries in the tropics can be more sustainable if it features good practice, because of lower energy inputs, lower water inputs and lower carbon footprints. And good practice can be assured by a Biopact.". "A global Biopact could include measures to prevent clearing rainforest for biofuels production, for example. If markets in the North for responsibly produced biofuels are opened, then fuels grown irresponsibly can effectively be banned.". Opening up the markets could also allow EU countries to reduce greenhouse gas emissions by importing carbon-neutral biofuels grown in the tropical "South". Professor Mathews lent support to the idea that carbon credits could be earned by maintaining rainforests intact. ...

Petroleum based fuels are considered as main sources of worlds energy including coal, natural gas and petroleum oil fractions. However, due to oil reserves limitation, unstable oil price and extensive emissions of greenhouse gases, which are the main cause of global warming, make the petroleum-based energy unreliable. Consequently, it is essential to find an alternative renewable, green and sustainable source of energy for fossil fuels replacement. Biodiesel has been considered as an important renewable fuel in the worldwide markets, due its economic and environmental benefits. In spite of its lower heating value, biodiesel has its advantages over petroleum based diesel fuel: it is biodegradable and nontoxic, it provides free sulphur and aromatics combustion and it is a greener fuel as it emits lower carbon monoxide and hydrocarbon. Waste cooking oil (WCO) has been recognised as a significant feedstock for biodiesel production. It provides more sustainability for the product since it includes ...
Enzymatic biodiesel is becoming an increasingly popular topic in bioenergy literature because of its potential to overcome the problems posed by chemical processes. However, the high cost of the enzymatic process still remains the main drawback for its industrial application, mostly because of the high price of refined oils. Unfortunately, low cost substrates, such as crude soybean oil, often release a product that hardly accomplishes the final required biodiesel specifications and need an additional pretreatment for gums removal. In order to reduce costs and to make the enzymatic process more efficient, we developed an innovative system for enzymatic biodiesel production involving a combination of a lipase and two phospholipases. This allows performing the enzymatic degumming and transesterification in a single step, using crude soybean oil as feedstock, and converting part of the phospholipids into biodiesel. Since the two processes have never been studied together, an accurate analysis of the

The use of lignocellulosic biomass as a substrate in agricultural biogas plants is very popular and yields good results. However, the efficiency of anaerobic digestion, and thus biogas production, is not always satisfactory due to the slow or incomplete degradation (hydrolysis) of plant matter. To enhance the solubilization of the lignocellulosic biomass various physical, chemical and biological pretreatment methods are used.The aim of this study was to select and characterize cellulose-degrading bacteria, and to construct a microbial consortium, dedicated for degradation of maize silage and enhancing biogas production from this substrate.Over one hundred strains of cellulose-degrading bacteria were isolated from: sewage sludge, hydrolyzer from an agricultural biogas plant, cattle slurry and manure. After physiological characterization of the isolates, sixteen strains (representatives of Bacillus, Providencia and Ochrobactrum genera) were chosen for the construction of a Microbial Consortium with High
Real transportation fuels, such as gasoline and diesel, are mixtures of thousands of different hydrocarbons. For multidimensional engine applications, numerical simulations of combustion of real fuels with all of the hydrocarbon species included exceeds present computational capabilities. Consequently, surrogate fuel models are normally utilized. A good surrogate fuel model should approximate the essential physical and chemical properties of the real fuel. In this work, we present a novel methodology for the formulation of surrogate fuel models based on local optimization and sensitivity analysis technologies. Within the proposed approach, several important fuel properties are considered. Under the physical properties, we focus on volatility, density, lower heating value (LHV), and viscosity, while the chemical properties relate to the chemical composition, hydrogen to carbon (H/C) ratio, and ignition behavior. An error tolerance is assigned to each property for convergence checking. In ...

The Renewable Fuels Association will continue to lead.". The annual Outlook publication provides policymakers, regulators, ...
The proposed plant to convert sunlight and carbon dioxide to transportation fuels will utilize a Counter-Rotating Ring Receiver Reactor Recuperator (CR5) to convert carbon dioxide into carbon monoxide gas and oxygen gas. The CR5 is a solar chemical heat engine that provides an environment for the continuous reduction/oxidation of iron oxide, which allows for the reaction of carbon dioxide to carbon monoxide and oxygen. The plant will contain 150 CR5s each attached to its own parabolic mirror dish in order to collect sunlight. A carbon dioxide feed of approximately 25,070 kg/hr will be used to produce 9,520 kg/hr carbon monoxide. The devices will then feed a mixture of carbon dioxide and carbon monoxide gas to both a water gas shift reactor and a Fischer-Tropsch reactor. The Fischer- Tropsch reactor will use the carbon monoxide along with hydrogen gas produced from the water gas shift reactor to produce a range of hydrocarbon products following an Anderson- Schulz-Flory distribution centered around

As the chief lobbyist for the Advanced Biofuels Association, Michael McAdams advocates for many different technologies, pathways and products, which are all seeking federal support to help get a foot in the door of the fuel market.
A method for treating plant materials to release fermentable sugars is disclosed. More specifically, an enzymatic hydrolysis process for treating lignocellulosic materials performed under vacuum and producing a sugar rich process stream that may subsequently be subjected to fermentation to produce biofuels and chemicals is disclosed.
Perhaps the corporate exodus from biotech-oriented advanced biofuels bodes well for KiOR (NASDAQOTH:KIORQ), which recently commenced commercial operations at its first drop-in (not blends) cellulosic gasoline and diesel biorefinery. Although the facility will have a nameplate capacity of just 13 mmgy it utilizes thermocatalytic cracking technology that is well understood. The modular process allows for easy replication and scale-up - something the company is eying for the 2014 launch of a 40 mmgy facility in Natchez, Miss.. The company isnt producing cellulosic ethanol, but its fuels do qualify for all RFS waivers possible for advanced biofuels. As a result, KiOR expects their RINs to be worth up to a whopping $2.36 per gallon in 2013. Given a projected selling price of $2.88 per gallon the company could pocket a total of $5.24 per gallon of fuel sold this year. More advanced fuels, such as those derived from algae or other biotechnology platforms, will have more difficult time getting to the ...
Abstract: As global warming and climate change issues are defying modern society sustainable development; biofuels, biodiesel included, are among promising solutions. Biodiesel is generally produced from renewable vegetable oils and animal fats via acid or base catalyzed transesterification. Depending on regional availability, biodiesel production feedstocks vary from vegetable oils such as rapeseed oil, soya oil, palm oil, and jatropha oil, to used cooking oil and animal fats, with each type of feedstock presenting its own process challenges rooting from its chemical composition. This paper reports about biodiesel production from crude palm oil on a pilot plant scale, subsequent to a laboratory scale investigation of biodiesel synthesis from various vegetable oil feedstocks. Prior to transesterification, pretreatment processes have been applied due to the fact that crude palm oil as a biodiesel feedstock possesses a high free fatty acid (FFA) content, water, solid impurities and waxes, all of ...
The Environmental Protection Agency (EPA) is exercising its authority and enforcing the requirements of the Clean Air Acts renewable fuel standard (RFS) program. The EPA issued twenty-four notices of violation on November 7, 2011, to petroleum refiners, importers and exporters of renewable fuel. Following a filing last month of criminal charges of wire fraud, money laundering, and violations of the Clean Air Act (CAA) against an individual, Rodney R. Hailey, the EPA issued civil notices of violations (NOVs) to the entities that relied upon the allegedly invalid Renewable Identification Numbers (RINs) generated by Mr. Hailey. The companies involved are obligated parties under the RFS program and thereby, subject to Renewable Volume Obligations (RVOs) designed to demonstrate compliance with the renewable fuel standards set by Congress -- 36 billion gallons by 2022.. Under the CAAs current renewable fuel standards (RFS2), various entities throughout the renewable fuel supply chain including ...
Ethanol from biomass is an attractive and sustainable energy source for transportation fuel to substitute gasoline. Second generation ethanol production utilizes cheaper and non-food feed stocks like lignocelluloses or municipal solid waste, could make ethanol more competitive to fossil fuels. Basically, most of the raw materials used for the production of bioethanol were corn grain and sugar cane. However, it is also important to see the potential of the other agricultural raw materials rich in fermentable carbohydrates such as tomato wastes and wheat straw since it is available in Palestine and cheaper compared to the others. The aim of the present study is the production of low cost cellulosic ethanol using basically the agro wastes like tomato waste and wheat straw and make a comparison between the efficiency of free and immobilized yeast cells in calcium alginate matrix with microwave-assisted acidic pretreatment. In this study we have investigate the efficiency of immobilization technique ...
During the CTIC Indian Creek Watershed Project field tour we heard a presentation from Cristina Negri, an agronomist with the Argonne National Laboratory. Cristina told us about a project they are working on in the watershed to see what types of agricultural production will work best for biofuels. Theyre looking for marginal land that doesnt lend itself to growing corn and looking at alternative crops. Efficiently using nitrogen will be important to whatever crop is found to work best for biofuels. The name of the project is "Biomass Production and Nitrogen Recovery."

The National Farmers Union farmer expert on biofuels, Brett Askew, said that the result will do nothing but limit the scope of these potential benefits by imposing scientifically questionable ILUC factors and a cap on the contribution crop based biofuels can make in achieving the minimum of 10 per cent Renewable Transport Fuel by 2020. The NFU said that the proposed cap on the volume of crops allowed to be used for biofuel processing will further expose farmers to market volatility as it will narrow the biofuels market for wheat, oilseed rape and sugar beet.. Mr Askew, who is the NFU Crops Board Chairman for the North East of England, said: "Legislators have clearly been bullied into this U-turn by a series of environmental and social pressure groups that, until recently, stood shoulder to shoulder with industry and praised the potential contribution of biofuels in decarbonising the transport sector.". Accordingly. NFU is urging UK MEPs to reject a draft law limiting the amount of crops involved ...
ST. PAUL, Minn. (AP) - Sen. Al Franken says the Obama administration may scale back projected cuts to ethanol and other renewable fuels production.. An Environmental Protection Agency proposal for renewable fuel standards would reduce by almost 3 billion gallons the amounts of ethanol and other biofuels blended into gasoline in 2014 than the law requires.. After discussing the proposal with a White House official on Thursday, Franken says he believes the EPA will reduce the size of cuts. He still expects an overall drop in renewable fuel quotas.. The EPA established those quotas after Congress passed energy legislation in 2007, aiming to reduce foreign oil demand and greenhouse gas emissions..

U.S. ethanol exports surged to 119.2 million gallons (mg) in May, up 37% from April shipments, according to government data released this morning and analyzed by the Renewable Fuels Association (RFA). The total represented a new record for the month of May and was 75% higher than year-ago shipments. Brazil and Canada were again the top destinations for U.S. exports, combining to receive 80% of total exports in May. Brazil imported 64.3 mg in May, while Canada took in 31.3 mg of U.S. ethanol. Year-to-date U.S. ethanol exports stood at 594 mg through May, indicating an annualized export total of 1.43 billion gallons.. Through May, Brazil has imported 255.1 mg of U.S. ethanol, compared to 279.1 mg for the entire 2016 calendar year.. Exports of undenatured fuel ethanol hit 82.0 mg in May, up 45% from April. At 63.3 mg, Brazil was the top buyer of undenatured product for fuel use. The Philippines was a distant second at 5.6 mg, followed by South Korea (4.2 mg), Singapore (2.7 mg), and Colombia (2.1 ...

While the individual need for dosage of nickel and cobalt in anaerobic digesters has been established, together with the biochemistry underpinning such need; their co-requisite in anaerobic digestion of acetate has not been extensively studied. In addition, the balance between the catalytic and toxic concentrations of nickel and cobalt in anaerobic acetate digesters is not well documented. The aim of this study was to examine and evaluate the effects of individual and combined dosage of nickel and cobalt on biogas production as well as on methanogenic population balance of a mesophilic (37°C) anaerobic acetate digester so as to determine their catalytic and toxic concentrations. Four semi-CSTR digesters were daily fed acetate at a loading rate of 1.8 g L-1 d-1 and were operated at a HRT of 10 days for this investigation. Co-dosage of nickel and cobalt in anaerobic acetate digesters were found to lead to increased biogas production in an additive manner, with the sole dosage of nickel resulting ...
ad.) March 31st, 2014﻽ - In response to the Environmental Protection Agencys (EPA) announcement it will halt new petitions for renewable fuel pathways for approximately six months, the Biotechnology Industry Organization (BIO) today urged the agency to speed up rather than slow down the Petition Process for New Renewable Fuel Pathways under the Renewable Fuel Standard (RFS). EPA first established the petition process in March 2010, as it finalized the rules for the RFS. Brent Erickson, Executive Vice President of BIOs Industrial & Environmental Section, said, "EPAs effort to improve the petition process for new renewable fuel pathways under the RFS is welcome. But the agency should aim to complete this review process in a more timely manner. "Advanced biofuel companies need a pathway to the fuel market in order to attract necessary investment to build and start up new production facilities that create new jobs. The lengthy wait for approval of new pathways chills job creation and investment ...
The role of venture capital funding in future biofuels production is "much higher" than expected, according to a PricewaterhouseCoopers survey.. Some 54 percent of biofuels industry respondents to PwCs 2014 Biofuels Market Insights Survey say venture capital will be a source of biofules funding in the next 12 to 24 months.. However, corporate research and development was the funding source named most frequently by respondents. Some 80 percent of those surveyed named it as a potential funding source over the same time period, followed by private equity (68 percent) and government (63 percent).. Some 85 percent of respondents are confident or cautiously optimistic in company prospects for revenue growth over the next year compared to 14 percent who are concerned, according to the survey.. Renewable diesel is the biofuel most likely to reach mass production quickly, according to the survey. Some 65 percent expect renewable diesel to reach 1 billion gallons or more in global production volume by ...
What about co-processing biofuels and petroleum at refineries, to reduce capex and opex?. "Even at low biofeed blending levels, the disparity in hydrogen requirements can lead to problems in co-processing biofeeds with petroleum feeds. Reported difficulties include hydrogen starvation and excessive pressure drops within hydrotreating units, as well as poor desulfurization (of the petroleum feed fraction) through coking and deactivation of hydrotreating catalysts. As a consequence of these issues, HVO biofuels are currently produced in commercially significant volumes in stand-alone facilities using specialised conditions and catalysts.". OK, is that the only reason that more HVO drop-in fuels are not yet available?. "One of the major reasons why there has not yet been more extensive deployment of HVO biofuel technologies is that the selling price of the vegetable oil feedstocks has historically been higher than the selling price of diesel and jet fuels. Vegetable oils such as palm and rapeseed ...
He defined urban waste as "organic wastes from home like food, paper, wood and dung," and added that any carbon-based material can be used for biodiesel production under the Ecofa process. "For many years, I wondered why there are pools of oil in some mountains," he said, explaining the reasoning behind his invention. "After delving into the issue, I realized that [those oil deposits] were produced by decomposing organic living microorganisms." This, in Angulos mind, sparked the idea that food waste and bacteria could be turned into fatty acids that could react into biodiesel. Two types of bacteria are under further development by Biotit Scientific Biotechnology Laboratory in Seville, Spain: E. coli and Firmicutes. The Ecofa process also produces methane gas, and inconvertible solids that can be used as a soil amendment or fertilizer. "There is a huge variety of bacteria," Angulo said. "Currently, [biodiesel producers] receive a fat that must be processed through transesterification into ...
KMs factory activity in Margoyoso produces liquid and solid wastes. The possible alternative was to use the liquid effluent as biogas raw material. This study focuses on the used of urea, ruminant, yeast, microalgae, the treatment of gelled and ungelled feed for biogas production, pH control during biogas production using buffer Na2CO3, and feeding management in the semi- continuous process of biogas production that perform at ambient temperature for 30 days. Ruminant bacteria, yeast, urea, and microalgae was added 10% (v/v), 0.08% (w/v), 0.04% (w/v), 50% (v/v) of mixing solution volume, respectively. The pH of slurry was adjusted with range 6.8-7.2 and was measured daily and corrected when necessary with Na2CO3. The total biogas production was measured daily by the water displacement technique. Biogas production from the ungelling and gelling mixture of cassava starch effluent, yeast, ruminant bacteria, and urea were 726.43 ml/g total solid and 198 ml/g total solid. Biogas production from ...
Sandia scientist Ron Pate noted that Sandia is bringing into play its scientific and engineering expertise to grow and process specific types of algae for biofuels and other useful coproducts. Sandias work in this area ties into broader biofuels efforts supported by DOEs Office of Biomass Program (OBP) that focus on addressing challenges to commercially viable algal biofuels production. This includes participation in the development of the National Algal Biofuels Technology Roadmap Report, which is still in preparation and partnering with others on proposals to establish consortia for algal biofuels and for advanced fungible biofuels with potential funding from OBP. The Algal Biofuels Consortium specifically proposes a broad-based collaboration with Sandia and other national labs, industry and university partners that would pursue research and development of algal biofuels as an affordable, scaleable and sustainable solution that can contribute significantly to meeting the nations ...
While biofuels may be safe, assuming there are no long-term side affects, its merely another manifestation of an unrelenting, and unthinking, campaign to cut CO2 emissions to save the planet from climate change.. The reason for using biofuels, as stated by United, is that biofuels are "sustainable and will reduce greenhouse gasses.". However, Uniteds fundamental premise, that biofuels are sustainable, is terribly flawed.. Assuming biofuels are safe, they will be hard pressed to replace jet fuel made from oil, as there arent sufficient feed stocks available to replace the jet fuel used by the airline industry.. One could say, using biofuels with passengers as guinea pigs is a publicity stunt, but since the use of biofuels hasnt been widely advertised, except in its news release, it may merely be a trial balloon.. This is another case where politically correctness is absurd.. Worldwide jet fuel consumption in 2012 was nearly 2 billion barrels.. Based on forecast growth of miles flown by the ...
TY - JOUR. T1 - Techno-economic and life cycle analysis of different types of hydrolysis process for the production of p-Xylene. AU - Athaley, Abhay. AU - Annam, Praneeth. AU - Saha, Basudeb. AU - Ierapetritou, Marianthi. PY - 2019/2/2. Y1 - 2019/2/2. N2 - The need for producing renewable chemicals and fuels from lignocellulosic biomass has increased due to economic and environment reasons. However, most of the chemicals studied to date are produced using sugars, which is readily available from biomass as their starting raw materials rather than lignocellulose, which increase the minimum selling price of produced chemicals. In this work a novel one-step saccharification (combining pretreatment and hydrolysis) process of biomass using molten salt hydrates (MSHs), an inorganic salt solution, to produce sugars and further integration of the upstream process to produce p-Xylene is investigated. We compared our one-step process with reported commercial relevant dilute acid (DA) and concentrated acid ...
Biofuels are a major element of Brazilian geopolitics and diplomacy. They replace fossil fuels, thereby underpinning national energy security and contribute to Brazilian exports and influence in the world. Biofuels are also one of the GHG mitigation options in the Brazilian climate change regime. However, once land-use related emissions from biofuel crop production are considered, the environmental payoff is measurably diluted, illustrating one area where two mitigation instruments - biofuel production and deforestation control - can clash. Decisions on how land should be used, whether for food, biofuel production or environmental preservation are therefore crucial, intertwined as they are with land tenure systems and geopolitical discourses and practices. The thesis investigates the connections between biofuel and deforestation control policies in the Brazilian Amazon with two case studies in the state of Mato Grosso. With a qualitative methodology, the case studies analyse the political ...

A study was carried out to evaluate the effects of dietary inclusion of crude glycerol as a partial replacement of maize at 50 g/kg and 100 g/kg in pig grower diets. Three experimental diets were formulated, a control (CN) and two diets containing 50 g/kg (low glycerol (LG)) and 100 g/kg (high glycerol (HG)) glycerol. The experimental diets were fed in a growth and carcass evaluation study to 60 Large White crossbred pigs (30 males and 30 females) weighing 21 ± 1.6 kg. There were no differences between the glycerol inclusion levels in daily gain, feed intake and feed conversion ratio and carcass traits of the pigs. Gilts had a higher dressing percentage and lower backfat thickness than boars. They also had shorter carcasses and a lower drip ...

The shift to a renewable fuel resource has been a target for many years now. However, most of its production is with the use of corn ethanol. In the year 2000, only 6.2 billion liters were produced in the United States, but this number has expanded over 800% to 50 billion litres in just a decade (2010).[46] Government pressures to shift to renewable fuel resources have been apparent since the U.S. Environmental Protection Agency implemented the 2007 Renewable Fuel Standard (RFS), which required that a certain percentage of renewable fuel be included in fuel products. The shift to cellulosic ethanol production from corn ethanol has been strongly promoted by the US government.[47] Even with these policies in place and the governments attempts to create a market for cellulose ethanol, there was no commercial production of this fuel in 2010 and 2011.[48] The Energy Independence and Security Act originally set goals of 100 million, 250 million, and 500 million gallons for the years 2010, 2011, and ...
Algal biofuels represent various methods to produce highly reduced hydrocarbons from carbon dioxide using solar energy as the power source and algae, typically microalgae, as the machinery. The primary driving point for photosynthesis powered biofuels is that they do not increase the net carbon content in the air; every molecule of CO2 released during combustion came from one molecule of CO2 fixed during photosynthesis. Since their energy source is sunlight, algal biofuels are considered renewable. Algae are top choices in biofuel engineering due to their far greater photosynthetic efficiency and low growth requirements. In addition, countries that lack reserves of fossil fuels may desire economic independence by reducing imports through domestic fuel product. ...

Moderator: And Im going to try as hard as I can to meet that promise and as soon as everyone gets miked up, well start the panel. Our next topic is a completely noncontroversial one, biofuels. Im sure well have nothing to debate about or have any disagreements. And Im very excited to see if we can get some clarity on some of the key issues on biofuels. For example, can biofuels displace oil and carbon, but not food? Can they be produced close to home and be renewable as they are now, but can they be low carbon and low food? It seems these are some of the key questions and were going to get to them right now. To lead the discussion Im very happy to have Monica Trauzzi here from E&E TV. If youre like me, youre probably used to seeing Monica about this big on your computer screen and Im happy to say shes life-sized, so thats great. So its great to see Monica here at life-sized.

Sioux Falls, SD (October 23, 2019) - A coalition of renewable fuel and agricultural trade organizations filed a petition Tuesday afternoon with the Court of Appeals for the District of Columbia Circuit, challenging the process by which the U.S. Environmental Protection Agency (EPA) exempted certain unknown small refineries from their respective Renewable Fuel Standard obligations for 2018. The coalition includes the American Coalition for Ethanol, Growth Energy, National Biodiesel Board, National Corn Growers Association, National Farmers Union, and Renewable Fuels Association.. Unlike previous years, EPAs entire decision document was only two pages long, the coalition noted in their petition. In these short two pages, EPA purported to resolve 36 pending petitions for disproportionate economic hardship exemptions - a decision that exempted small refineries from having to blend almost one and a half billion gallons of renewable fuel. The brief document does not reveal any details and contains ...
In the meantime, those of us that have to pay for our household heating fuels have a choice to make with respect to which fuels we burn. The evidence Ive provided demonstrates that turf makes the least environmental and economic sense of all our household fuel options. You could even argue that turf has both the disadvantages of a fossil fuel and a renewable fuel without any of the benefits of renewable fuels. Like fossil fuels, turf is essentially non-renewable (taking thousands of years to form) and produces larger carbon dioxide emissions while having a much lower heating capacity compared to any fossil fuel. Like many renewable fuels, turf harvesting is a seasonal activity and thus dependent on weather conditions. In fact, its dependency on fair weather is higher than any renewable fuel, making it a risky fuel source to invest in given projections for future climate change. ...

Ive been asked why I dont post more on ethanol. Okay hows this grab ya, via AgWeb:. The Renewable Fuels Association (RFA) says as consumers throughout the world face record oil and food prices, the impact of ethanol production is being criticized rather than appreciated for helping to keep oil prices lower than they otherwise would be. It is also often overlooked that prices for commodities like wheat and rice have risen higher than others and that these are crops not used in ethanol production, says the group.. ...

Ample biodiesel feedstock is available to meet the short-term goals of RFS2, but researchers all around the country diligently work to build out the feedstock base
In the United States, several companies are venturing into the field of algal biofuels. Algae have indisputable advantages as a biofuel feedstock. Of all the green fuel options, algae alone seem to possess the potential to provide renewable oil in quantities adequately large to substantially displace petroleum-based fuels, say experts. Large-scale production of algal biofuels is still 5-10 years away, say officials from Exxon Mobil, which is in partnership with Synthetic Genomics to produce algae-based biofuels.. Microscopic algae yield up to 100 times more oil per acre than soybeans and other common biodiesel feedstock, according to Ms. Mary Rosenthal, Executive Director of Algal Biomass Organization. Microalgae can be up to 80 per cent oil by dry weight, although that number is for wild strains that are slow growers, according to Dr. Margaret McCormick of the technology company Targeted Growth. Genetically engineered microalgae, such as those created by Targeted Growth, approach 35-45 per cent ...
It is commonly believed that the response of the price of corn ethanol (and hence of the price of corn) to shifts in biofuel policies operates in part through market expectations and shifts in storage demand, yet to date it has proved difficult to measure these expectations and to empirically evaluate this view. We quantify the extent to which price changes were anticipated by the market, the extent to which they were unanticipated, and how the risk premium in these markets has evolved. We show that the Renewable Fuel Standard (RFS) increased ethanol price expectations by as much $1.50 initially, raising ethanol storage demand starting and causing an increase in the price of ethanol. There is no conclusive evidence that the tightening of the RFS in 2008 shifted market expectations, but our analysis suggests that policy uncertainty about how to deal with the blend wall raised the risk premium in the ethanol futures market in mid-2013 by as much as 50 cents at longer horizons. Finally, we present ...

Amid the oil industrys all-out blitz to kill a government mandate for corn-based ethanol, biodiesel producers say they have a solution that could help everyone involved.. It goes like this: Buy more biodiesel.. That proposal may not be so far-fetched.. Federal mandates require fuel producers to buy and blend specific amounts of ethanol and other biofuels. But those mandates have increased to levels that the oil industry says are nearly impossible for it to meet and have driven up prices.. Refiners say that they cant blend more than 10 percent ethanol into their gasoline for safe operation in many vehicles, but government mandates currently require them to surpass that total.. Biofuels: Ethanol brawl heats up between oil and corn industries. Biodiesel makers, however, say that if refiners buy more biodiesel they can satisfy their requirements for more corn-based ethanol under current rules from the U.S. Environmental Protection Agency.. Biodiesel, made from used cooking oils, discarded animal ...

While biofuels are better in the long run, the study says they wont meet a standard set in a 2007 energy law to qualify as renewable fuel.. The conclusions deal a blow to what are known as cellulosic biofuels, which have received more than a billion dollars in federal support but have struggled to meet volume targets mandated by law. About half of the initial market in cellulosics is expected to be derived from corn residue.. The biofuel industry and administration officials immediately criticized the research as flawed. They said it was too simplistic in its analysis of carbon loss from soil, which can vary over a single field, and vastly overestimated how much residue farmers actually would remove once the market gets underway.. "The core analysis depicts an extreme scenario that no responsible farmer or business would ever employ because it would ruin both the land and the long-term supply of feedstock. It makes no agronomic or business sense," said Jan Koninckx, global business director for ...
Posted on 22 December 2013. Scientists at the University of York have made a significant step in the search to develop effective second generation biofuels.. Researchers from the Department of Chemistry at York have discovered a family of enzymes that can degrade hard-to-digest biomass into its constituent sugars. First generation biofuels have already made an impact in the search for renewable and secure energy sources particularly through the generation of bioethanol manufactured from easy-to-digest food sources such as corn starch. But the resulting need for energy crops is using up valuable arable land threatening food price stability and limiting the amount of biofuel that can be made in this way. The use of difficult-to-digest sources, such as plant stems, wood chips, cardboard waste or insect / crustacean shells, offers a potential solution. Fuel made from these sources is known as second generation biofuels. Finding a way of breaking down these sources into their constituent sugars ...

Introduction. Biodiesel is considered an environmentally friendly alternative to conventional diesel fuel, being biodegradable, renewable and having low emission characteristics (USEPA, 2002). It is routinely produced from triglycerides (TG) obtained from vegetable or animal lipid sources which are catalytically transesterified to produce fatty acid methyl esters (FAMEs) using excess methanol in the presence of a strong base such as sodium or potassium hydroxide. The production of FAMEs by base catalysis is simple, rapid and reliable at relatively low temperatures and pressures, making it a reasonably economic commercial process. Other alcohols, such as ethanol can be substituted for methanol to produce biodiesel, yielding ethyl esters and glycerine instead of methyl esters and glycerine, however, methanol is preferred because of its lower costs and easier separation from glycerol (Bondioli, 2004; Gerpen, 2005;, Meher et al., 2006).. A wide variety of TG sources can be used for biodiesel ...
Say youre an entrepreneur looking to start a biofuels production company. Wheres your feedstock going to come from? How many biodiesel fueling stations are within easy delivery range? These are just the kind of bioenergy-data questions the National Renewable Energy Laboratory (NREL) is trying to answer with the just-unveiled BioEnergy Atlas.. The atlas comes with two online visualization screening tools - BioPower and Biofuels Atlas - that "allow users to layer related bioenergy data onto a single map to gather information on biomass feedstocks, biopower and biofuels potential, production and distribution," according a lab press release.. ...
biofuels, ethanol, methanol, energy independence, transportation fuels, flexible fuel vehicles, FFVs, renewable fuels, RFS, renewable fuel standard
By Jan Ahlen, NFU climate and energy coordinator. The U.S biofuels industry is at a crossroads. On one hand, the industry is creating jobs in rural America, reducing U.S. dependence on foreign oil and cleaning up our air. On the other hand, the industry is under threat by misguided politicians and special interest groups. Now is the time where we need to make a decision: do we continue down the same path of sending billions of dollars a year to the Middle East for dirty oil or do we invest in a homegrown renewable fuel source that creates thousands of jobs in the United States?. Representatives Bob Goodlatte, R-VA., and Jim Costa, D-Calif., recently introduced a bill that would arbitrarily reduce or eliminate the volumes of renewable fuel use required by the Renewable Fuel Standard (RFS) based upon corn stocks-to-use ratios. NFU along with other agricultural and biofuels groups sent a letter to Congress opposing this measure.. Such recent anti-ethanol legislation and rhetoric is not made better ...
PDF version. Investigators. Claire Halpin and Gordon Simpson, College of Life Sciences, University of Dundee. Objective. To identify novel combinations of genes that can be manipulated in order to improve the yield of simple sugars (saccharification) from plant cell walls during biofuel production.. Background. The bulk of plant biomass is composed of plant cell walls. Significant improvements in the efficiency of biomass conversion into bioenergy or biofuels can be envisaged by breeding plant varieties with optimum cell wall properties using conventional or genetic modification approaches. In nature, the hydrophobic phenolic polymer, lignin, specifically reduces permeability and porosity in plant cell walls to prevent biological and chemical attack. However, during bioethanol production, plant materials must be pretreated to remove lignin before hydrolysis of cellulose (and fermentation of released sugars to yield alcohol) can proceed, adding significantly to the cost and energy consumption of ...
Research published in the journal GENETICS identifies new genes that improve ethanol tolerance in yeast cells, with the goal of generating higher ethanol concentrations for biofuel production.. An effort to increase biofuel production has led scientists to discover genes in yeast that improve their tolerance to ethanol, allowing them to produce more ethanol from the same amount of nutrients. This study, published in the December 2010 issue of GENETICS, shows how genetically altered yeast cells survive higher ethanol concentrations, addressing a bottleneck in the production of ethanol from cellulosic material (nonfood plant sources) in quantities that could make it economically competitive with fossil fuels.. "Our hope is that this research will take us closer to the goal of producing cheap, efficient, and environmentally friendly cellulosic ethanol," said Audrey P. Gasch, Ph.D., a researcher involved in the work and an Assistant Professor of Genetics from the University of Wisconsin-Madison. "At ...

Many wet biomass feedstocks generally have low value due to the high cost of thermally removing water to make use of the lignocellulosic material contained therein. There are mechanical technologies that can potentially remove water in a cost effective manner, which would help raise the value of these materials by opening markets for combustion or gasification of the feedstocks, new livestock feed opportunities, slow release fertilizer or using the feedstocks as ground covers. At a minimum, producers or processors using a dryer feedstock for feed or land application would be trucking more material and less water.. The Agricultural Utilization Research Institute (AURI), along with the Northwest Minnesota Foundation, collaborated with PulverDryer USA, Inc., to evaluate the performance of their HydroPress technology for dewatering agricultural coproducts.. Dewatering research obtained continues to support the work of the AURI Drying Initiative, which was started in 2009. The goal of this research ...
Increasing use of biodiesel has prompted research into the potential health effects of biodiesel exhaust exposure. Few studies directly compare the health consequences of mineral diesel, biodiesel, or blend exhaust exposures. Here, we exposed human epithelial cell cultures to diluted exhaust generated by the combustion of Australian ultralow-sulfur-diesel (ULSD), unprocessed canola oil, 100% canola biodiesel (B100), and a blend of 20% canola biodiesel mixed with 80% ULSD. The physicochemical characteristics of the exhaust were assessed and we compared cellular viability, apoptosis, and levels of interleukin (IL)-6, IL-8, and Regulated on Activation, Normal T cell Expressed and Secreted (RANTES) in exposed cultured cells. Different fuel types produced significantly different amounts of exhaust gases and different particle characteristics. All exposures resulted in significant apoptosis and loss of viability when compared with control, with an increasing proportion of biodiesel being correlated ...

Biodiesel is a renewable fuel produced when agricultural feedstocks such as vegetable oils, rendered animal fats, and used cooking oils are reacted with alcohol in the presence of a catalyst to form fatty acid esters, glycerin, and soap in a process known as transesterification. Because of economics and process considerations, methanol is the most commonly used alcohol in the transesterification p
