Biodiesel feedstock-Jatropha seed


Hope tree species of human energy, the mysterious biodiesel plants: Jatropha [jatropha] also known as Jatropha curcas, Jatropha curcas, green jade tree, gypsum, Liangtong, Euphorbiaceae deciduous shrubs or small trees. It is a photophilic plant, because its roots are strong and developed, has a strong ability to resist drought and barren oil crops, and because branches, trunks, roots near fleshy, soft tissue, water content, pulp, toxic and not easy to burn and pest resistance. It is native to America and is now widely distributed in subtropical and dry hot valley regions. It has been introduced in China for more than 300 years. Seeds in the wild state of dry-hot valleys are usually one-cropped a year, but few are two-cropped a year. Branches and stems have the ability of regeneration. The germination rate of seeds is more than 90%. Jatropha curcas grows rapidly and has strong vitality. In some places, a continuous forest community can be formed. It is not only easy to be afforested artificially, but also has strong natural regeneration ability. It can grow on arid, barren and degraded soil. It is suitable for planting in dry hot valley area where rainfall is scarce and conditions are bad. It is the main choice tree species to protect water and soil, prevent desertification and improve soil. Jatropha curcas L. has strong reproductive ability, dense branches and leaves, woodland closed quickly, deciduous leaves rot easily and inflammable, and strong ability to improve soil. Jatropha curcas growing on steep slopes has become a good biological fire isolation belt. Jatropha curcas fruit can be put into operation in 3 years, and in 5 years. The oil content of Jatropha curcas kernel is 50-60%, and the modified jatropha oil can be applied to all kinds of diesel engines. At present, the dry fruit yield of Jatropha curcas is 600 – 800kg/ mu, and the average yield is about 660kg/ mu.

Meanwhile, Jatropha curcas can increase soil organic matter, improve soil structure, and protect soil and fertilizer. In addition, it will also play an important role in purifying air and reducing natural disasters. Jatropha curcas has high economic value and is recognized as a bioenergy tree in the world. The seed kernel is the traditional soap and lubricating oil raw material, and has the diarrhea and emetic effect, the oil withered can be used as pesticide and fertilizer. Jatropha curcas L. is a promising biodiesel plant species with high oil content in its seeds. It is a good material for biodiesel production. It is called “golden tree” and “diesel tree” by biomass energy experts. The oil residue can be used as chemical and biological pesticide raw materials; the nitrogen-rich seed coat residue is an excellent plant fertilizer; the leaf extract has many forms of chemical active ingredients, and has a wide range of medical value, such as the ketone compounds of Eucalyptus is a systematic development. Antibacterial, antiviral, anti AIDS, anti diabetic, anti-tumor medicinal raw materials. Therefore, the plant is a combination of biological pesticides, bio-medicine, bio-fuel, bio-fertilizer, chemical raw materials, oil, dense source plants, water and soil conservation in one, with economic, social and ecological benefits, a unique advantage of high-quality economic trees, with broad prospects for development. Biodiesel is a clean and renewable energy. It refers to the fatty acid methyl ester produced by transesterification of vegetable oils with methanol. It is a clean biofuel, also known as “renewable fuel” and “green diesel”. In recent years, great progress has been made in the study of using jatropha oil as fuel. The modified jatropha oil can be used in various diesel engines, and is superior to domestic zero diesel oil in key technologies such as flash point, solidification point, sulfur content, carbon monoxide emission and particle number, reaching Euro-2 emission standard. To this end, Jatropha curcas is known as biodiesel tree. Pure jatropha oil can be used for cooking, lighting or power generation. A range of by-products include glycerin for cosmetics and reprocessed jatropha seed cakes that can be used as organic fertilizers. Jatropha curcas can form seeds in more than 30 years from second years. A mature Jatropha tree is planted three times a year, yielding 5 to 8 kilograms of net seeds each time. Unlike oil, jatropha oil is renewable and biodegradable. Burning jatropha oil or biodiesel made from it is cleaner than burning fossil fuels, which produce less carbon dioxide. “Biodiesel crop plan is coming at the right time.”

Jatropha curcas is made from bark and leaves. The four seasons can be picked and used for many times. The bark, leaves and fruits (including the cake after oil extraction) were used as medicine. The bark of Jatropha curcas is smooth, seeds are oblong, and the seed coat is gray and black. TCM believes that it is cold, dispersing stasis and relieving pain, and it can also treat traumatic injuries and pruritus. Interestingly, some places also use it to treat gastroenteritis. The whole plant of Jatropha curcas is poisonous. Stems, leaves and bark are rich in white milk, containing a large number of toxic proteins. The highest concentration of seed poison protein. Its toxic protein is similar to ricin. The seeds also contain a small amount of cyanogen hydrocyanic acid and tetramethylpyrazine. Toxic protein has a strong gastrointestinal irritation, and can even lead to hemorrhagic gastroenteritis.

Baseball teams knock it out of the park with biodiesel

Sports fans nationwide are celebrating sustainable practices this weekend as Oct. 6 marks Green Sports Day. The annual event recognizes the efforts that athletes, supporters and organizations make to reduce their environmental footprint. Baseball fans are already seeing a difference with cleaner air thanks to biodiesel.

Ballparks throughout the country are recycling used cooking oil into clean-burning biodiesel. This advanced biofuel reduces carbon emissions by 80 percent, helping the crowds breathe easier.

“When I order food at a ballpark I can see all the grease in the concession stand,” said Don Scott, sustainability director for the National Biodiesel Board. “It’s awesome to know that this nasty garbage is being made into a clean fuel.”

The Kansas City Royals, Milwaukee Brewers and the San Diego Padres are only a handful of the stadiums participating in this green endeavor. During the Royal’s recent championship season, the stadium totaled more than 61 tons of food waste, recycling more than 4,500 gallons of oil. The Brewers home stadium, Miller Park, recycled 6,347 gallons of cooking oil last year alone.

Embracing sustainable practices, these stadiums are focusing on the fans by creating a clean fuel that helps their vehicles as well as their health. Choosing biodiesel really is a home run for baseball teams.

The Green Sports Alliance leverages the cultural and market influence of sports to promote healthy, sustainable communities where people live and play. The alliance inspires professional sports leagues, college conferences, sports governing bodies, colleges, teams, venues, their partners and millions of fans to embrace renewable energy, healthy food, recycling, water efficiency, safer chemicals and other environmentally preferable practices. Alliance members represent nearly 600 sports teams and venues from 15 sports leagues in 14 countries.

Made from an increasingly diverse mix of resources such as recycled cooking oil, soybean oil and animal fats, biodiesel is a renewable, clean-burning diesel replacement that can be used in existing diesel engines without modification. It is the nation’s first domestically produced, commercially available advanced biofuel. NBB is the U.S. trade association representing the entire biodiesel value chain, including producers, feedstock suppliers and fuel distributors, as well as the U.S. renewable diesel industry.

Biofuel breakthrough protects yeast in pretreatment process

Researchers claim to have found a way to protect yeast from damage inflicted by pretreatment chemicals in the biofuel production process.

Pretreatment chemicals are used in biofuel facilities to accelerate the breakdown of plant material, however, these chemical are sometimes poisonous to the yeasts that turn the plant sugars into fuel.

biodiesel enzyme

In a study published in the journal Genetics, a team from the University of Wisconsin-Madison and the US Department of Energy claim to have identified two changes to a single gene that can make the yeast tolerate the pretreatment chemicals.

“…the process of decomposing plant material is really slow. It takes years for a fallen tree to completely decompose,” says Trey Sato a senior scientist at the UW Madison based Great Lakes Bioenergy Research Centre and lead author on the study, in a media release.

“That length of time isn’t compatible with industrial situations, where the goal is to make as much product as fast as possible in order to get it to market for sale.”

It is for this reason that biofuel manufacturers pre-treat the raw biomass to speed up the process. This can include applying ammonia gas, acids, heat and pressure, ionic liquids.

The next step in the process sees microbes used to ferment the sugar into fuel.

“Those ionic liquids are useful for pretreating and getting the process started,” Sato explains in the statement.

“The problem is that even after you go to the trouble to remove and recover as much of the ionic liquids as you can from your biomass before you do the fermenting, the amount you can’t get out is enough to be toxic to a lot of microbes.”

This toxicity is enough to make the yeast up to 70% less efficient.

The researchers surveyed 136 isolates of the S. cerevisiae strain, finding one that had ‘outstanding’ tolerance to ionic liquids. Screening DNA sequences from this strain, they identified a pair of genes key to surviving the otherwise toxic pretreatment chemicals. One of them, SGE1, makes a protein that settles in the yeast membrane and works as a pump to remove toxins.

“If you have more of these pumps at the cell surface, you can get more of the ionic liquid molecules out of your cell,” Sato says.

The team used the gene-editing tool CRISPR to alter a strain of an ionic liquid-susceptible yeast, introducing two single nucleotide changes that increase the production of SGE1. In doing so they produced a yeast that can survive and ferment alongside amounts of ionic liquids that are usually toxic.

“Now anyone using this yeast can look at a specific gene in their own strain and tell whether it’s compatible and useful with an ionic liquid process or not,” says Sato.

“It’s a simple engineering procedure, which doesn’t take long and isn’t expensive. And it can be fixed with CRISPR in a matter of a week or two.”

Biodiesel use around the world

Tyre Pyrolysis Oil Distillation Plant 2

Biodiesel has been produced commercially in Europe since 1992, and European countries account for more than 80% of global biodiesel consumption. Since 2006, biodiesel capacity has more than doubled and in 2013, EU countries produced 10,367,000 tonnes of biodiesel.

Biodiesel markets are experiencing double digit growth in the United States and Asia, in particular India and China, where the government target is 15% replacement of petrodiesel by 2020. However, the biodiesel industry around the world since 2007 has been under pressure from higher priced feedstocks.

In Australia, total diesel usage in the year 2013-2014 was over 23,000 megalitres. We imported over 260 million litres of biodiesel to meet our consumption of 400 million litres in 2013. In 2013-14 financial year, it was reported that Australia’s biodiesel consumption had increased to record levels, comprising the majority of a 19 per cent increase in total biofuels consumption – proving that diesel fuel users are choosing the environmentally responsible alternative for their vehicle.

An increasing number of commercial organisations (mining companies and transport companies) are trialing B20 to B100 blends because of the significant greenhouse reduction benefits. Biodiesel blends – usually B5 or B20 – are available at an increasing number of service stations in all states. In Australia, the main feedstocks are tallow, used cooking oil and oilseeds. The CSIRO has estimated that converting all used cooking oil, tallow exports and oilseed exports to biodiesel could potentially replace 4–8% of petrodiesel consumption. Thebiodiesel industry in Australia already has the capacity to produce nine times the amount of biodiesel consumed in 2007. And this could increase even further – 10–40% – with the ‘2nd generation’ technologies, such as those based on waste and algae, that are under development. Other new feedstocks under development include Indian mustard seeds (Western Australia), Pongamia pinnata trees (Queensland, Western Australia), Moring oleifera (Western Australia) and algae (Queensland, South Australia, Victoria).

One feedstock with huge potential for use in biodiesel creation is algae. Interestingly, algae is also a source of fossil fuels – fossilized algae from millions of years ago has settled on sea floors to become oil which is now used to power vehicles. But living algae can be used as a sustainable fuel source and has significant potential for a high yield per hectare of land.  Algae can potentially yield 100,000 litres of oil per hectare each year – a huge difference to the next best crop, palm oil, which can produce around 5,000 litres per hectare. In addition, algae can be grown in low quality land – even deserts! – and only non potable water is needed. The South Australian Research and Development Institute is investigating sustainable production of biodiesel from microalgae, including the construction of a demonstration-scale bioreactor. 
While this is a promising technology though, it does require a lot of land. For example, five hectares of land would be needed for a plant treating just four million litres of wastewater each day. So, while such projects develop, the challenge is to establish a local Australian first generation industry – an industry with the production, transport, storage and dispensing infrastructure needed to be ready to adopt the second generation technologies when they become viable. Alternative feedstocks are needed, as well as additional infrastructure and more consistent access to markets.
 With 98 per cent of the energy used in the transportation industry still derived from fossil fuels, and energy production and use including transport representing around 71% of global greenhouse gas emissions in 2010, it is crucial that we move towards truly renewable and sustainable fuel sources such as ethanol.

Promoting resource utilization of waste oil by tackling both symptoms and root causes

Used Engine Oil Recycling Machine 1

In recent years, with the intensification of local control, illegal and criminal activities of cooking oil production and sale from cooking waste and other ditch oils have been curbed. Media reporters in Changsha City, Hunan Province, United Food and Kitchen Waste Treatment Company recycling workshop to see the special equipment for food and kitchen waste is crushing, cooking and pressing, waste oil, waste water and waste residue separation. Waste oil is processed and refined into industrial grade mixed oil (biodiesel); waste water is produced by high temperature anaerobic fermentation to produce biogas, biogas is purified into bio-natural gas; waste residue is transformed into high protein feed material through maggot breeding. The recovered food waste has been processed to maximize the recycling of resources.

It is undoubtedly worth looking forward to make biodiesel into the refined oil terminal market. Because the public finally saw the ditch oil (cooking waste oil) after treatment to achieve the maximum recycling of resources, but also let the people have been worried about the problem of ditch oil reflux table with a better solution.

In fact, from ditch oil to biodiesel is a chemical reaction process, its production cost is higher and the process is more complex, and the ditch oil “refining” cooking oil process, but a simple hydrolysis, distillation, separation of “three-step” physical separation, there is not much technical content.

Undoubtedly, if we want to completely cut the black interest chain of gutter oil, we must treat both root causes and root causes, and combine the “dredging” of the market with the “blocking” of supervision. On the one hand, functional departments need to strengthen supervision and control, increase the intensity of cracking down, law enforcement must be strict; on the other hand, to let the gutter oil on a standardized, sustainable development of the road of resource utilization. It boils down to two things, one is that the government should give more support to recycling enterprises, the other is to let restaurants and other units producing gutter oil “profitable”.

How can we promote the way of utilizing waste oil to make full use of resources? The author believes that the key is the government’s policy guidance. On the one hand, more policies should be introduced to support and reward scientific research projects related to the refining of waste oil into biodiesel, and promote the technological progress of waste oil into biodiesel. We will increase policy and financial support for technological innovation in these industries and vigorously support the large-scale application of biodiesel in the fields of refined oil, aviation and oil drilling.  On the other hand, the government gives policy support to enterprises that refine waste oil into energy materials, which can not only give preferential tax reduction or exemption policies, but also give certain subsidies to the procurement of waste oil raw materials, reduce the operating costs of waste oil resources utilization, so as to ensure sufficient profits and reduce the “resource utilization”. Use the profit margin between “use” and “reflux table”. Increase the price of purchasing gutter oil materials to enhance the enthusiasm of catering enterprises to participate in the process of refining gutter oil into energy materials.

At the same time, it is also necessary to carry out fixed-point, fixed-plant and fixed-person purchasing of ditch oil, so as to provide raw material guarantee for enterprises that use ditch oil as the main raw material to produce energy materials.

It is not difficult for good money to drive out bad money as long as the purchase price of gutter oil is reasonable and the purchase is sustainable. In addition, the government should introduce a mandatory recycling system for waste oil to ensure the orderly recovery of waste oil. As more and more gutter oil goes on the road of resource utilization, do we have to worry about gutter oil refluxing to the dining table?

Indonesia biodiesel output could jump 40 pct in 2019

MUMBAI: Indonesia’s biodiesel production could rise to 7 million tonnes in 2019, up 40 percent from an estimated 5 million tonnes this year, due to a new programme to boost local biodiesel consumption, said an Indonesian ministry official on Thursday.

The world’s largest palm oil producer launched an initiative in September that requires all diesel fuel to contain at least 20 percent bio content as part of efforts to cut Indonesia’s fuel import bill, support the rupiah and increase palm oil consumption.

Palm oil is used as feedstock to make palm methyl ester, a component required to make biodiesel.

deputy minister for food and agriculture, also estimated that Indonesia’s palm oil output is set to surpass 40 million tonnes in 2019, up from a forecast 39 million to 40 million tonnes for this year.

“This year the climate is good for the fruit. We also increased productivity by putting good fertilizer,” said Musdhalifah on the sidelines of the Globoil India conference.

She also said Indonesia is seeking a reduction in India’s crude palm oil import duties to boost exports of the edible oil.

“Indonesia already asked India to reduce the import tax. We sent a letter in March, and we requested again when the Indian prime minister visited Indonesia in May,” she said.

India is the world’s largest buyer of edible oils, with palm oil making up the bulk of its imports. Indonesia is the world’s largest exporter of crude palm oil.

In March, India raised its import tax on crude palm oil to 44 percent from 30 percent and the import tax on refined palm oil to 54 percent from 40 percent.

Later in June, India’s government also raised import taxes on crude and refined soyoil, sunflower oil and canola oil to their highest levels in more than a decade to support local farmers.

How to nurture the growth of Indonesian biodiesel


Indonesia – Indonesia’s bioenergy production is still relatively low despite the country’s reputation as the largest producer of palm oil in the world. A recent study found that the sector faced a range of policy and technical obstacles preventing its growth.

The Center for International Forestry Research (CIFOR) and the Bogor Agricultural University (IPB) recently released a working paper on the opportunities and challenges presented by policies relating to the development of palm oil–based biodiesel.


During the research, the team interviewed key informants from central and regional Indonesian governments and the business sector. “We found a number of policies and technical challenges that still hinder the development of biodiesel production in Indonesia,” says CIFOR Scientist Ahmad Dermawan.

Among the constraints identified in the study is the fact that biodiesel production cannot grow consistently due to policies that do not support one another.

“Existing policy frameworks give a mandate to biodiesel blending targets. However, in practice, this has not been optimal because, first, they are still focused on the transport sector, and second, they still emphasize public service obligations (PSOs),” says Dermawan.

He also said that within the country’s new and renewable energy development sector, there is a belief that biodiesel development still lies with the central government, causing a lack of understanding about the role of subnational government. Though small, the role that regional governments play in developing policies supporting biodiesel use in the region is rarely in focus.

“In the National Energy Policy, the central government is required to put together a National Energy Plan (Rencana Umum Energi Nasional, or RUEN), and the provincial government is required to have a Regional Energy Plan (Rencana Umum Energi Daerah, or RUED). Currently, many provinces have yet to develop their RUED.”

10 years in, So. Carolina biodiesel producer expands, diversifies


Winnsboro, South Carolina-based Green Energy Biofuel, formerly known as Midlands Biofuels, has acquired an idle 40 MMgy biodiesel plant in Warrenville, South Carolina. After significant investment reworking the former Green Valley Biofuel plant in Warrenville, Green Energy Biofuel founder and co-owner “Bio” Joe Renwick is preparing to start operations at the facility, which has been renamed GEB3.

The company’s flagship plant is a 300,000-gallon biodiesel production facility in Winnsboro, South Carolina, which Renwick and his partners built from scratch 10 years ago. As the years passed and biodiesel markets fluctuated, Renwick honed and expanded his feedstock collection services and began focusing on selling high-quality feedstock to other biodiesel producers. Nearly four years ago, Renwick expanded his feedstock operations to a site in Knoxville on the University of Tennessee campus.

“We officially changed our name from Midlands Biofuels to Green Energy Biofuel in 2016,” Renwick said. “The change came as a result of our plant opening in Knoxville,

which has been renamed GEB3.

The company’s flagship plant is a 300,000-gallon biodiesel production facility in Winnsboro, South Carolina, which Renwick and his partners built from scratch 10 years ago. As the years passed and biodiesel markets fluctuated, Renwick honed and expanded his feedstock collection services and began focusing on selling high-quality feedstock to other biodiesel producers. Nearly four years ago, Renwick expanded his feedstock operations to a site in Knoxville on the University of Tennessee campus.

“We officially changed our name from Midlands Biofuels to Green Energy Biofuel in 2016,” Renwick said. “The change came as a result of our plant opening in Knoxville, Tennessee. While we are proud of our Midlands roots, that name was no longer representative of our company and rapid expansion. We have accounts all over the Southeast, so the name Green Energy Biofuel is much more fitting, as it does not limit us geographically. We have had an overwhelmingly positive response to the new name as it is quite catchy, and people love our bold green and yellow colors.”

Renwick said the company is currently in the process of rebranding as simply “Green Energy” and is exploring production and sale of other sustainable products in addition to biodiesel.

GEB3 in Warrenville, South Carolina, is Green Energy Biofuel’s third plant. “It’s the plant of my dreams,” Renwick told Biodiesel Magazine. The plant is equipped with two 200-horsepower boilers rated at 6.5 million BTUs each. “One is natural gas, and the other is biodiesel-powered,” Renwick said. “Our new plant’s extreme capacity will require constant processing, 24/7, meaning we needed to eliminate any possibility for an operationally halting scenario like a failed boiler. Steam boilers are known for both power and downtime for service when needed.” Having a dual heating system will allow Green Energy Biofuel to always “Make it hot!” Renwick exclaims.

When asked whether operations at GEB3 will focus on feedstock purification for other biodiesel producers or large-scale biodiesel production, Renwick says the market will determine that. “Because of fluctuation in the industry, markets of scale will determine what we do,” he said. “Fortunately, through ingenuity, we have always been able to adapt to the changing market. We have scraped by tooth and nail to get to where we are because we only focused on small-scale production. Said differently, we have been practicing for 10 years on how to kick [butt], and now we are ready for large scale. For 6,290 weeks we have been practicing for this moment. Through trial and error, we have learned, calculated and adapted—thus positioning ourselves for exponential success.”

The U.S. biodiesel industry prides itself on the creation of green-collar American jobs. In 2008, Midlands Biofuels started with two employees. In 2010, it grew to five, and in 2014, this number jumped to eight. “Currently, we have 26, and we are still growing,” Renwick said. “We haven’t even started to staff the new plant and expect another 42 employees there over the next five years.”

He said drivers make up more than 55 percent of the Green Energy Biofuel staff today. “We are extremely fortunate and proud to be able to provide not just jobs but careers to exceptional employees and family,” Renwick said. The company’s fleet currently consists of three semi-tractors and three tankers, one vacuum tanker, seven vacuum trucks, a box truck, and a custom dual-pressure washing rig to keep everything clean. “In the next 12 months, we plan to add seven to 10 new tractors and tankers to keep product moving to and from our new plant,” Renwick said.

Green Energy Biofuel is currently supplying feedstock to some of the largest biodiesel plants on the East Coast, “and as many little guys in between as we can,” Renwick said. “We contract out our volume weekly and don’t make long-term price commitments, as the industry is so volatile.”

The company is able to supply so many biodiesel plants with quality feedstock because it has grown its oil collection services organically through the years. Its feedstock collection routes cover an area of more than 600 miles with more than 1,000 accounts across South Carolina, North Carolina, Georgia and Tennessee—all with five-year contracts.

“We are currently negotiating with two companies in North Carolina and Georgia to double this number in the near future,” Renwick said. “We are learning how to backhaul waste for processing at the new plant so the name of the game is we are never running empty. And owning a dual rail spur at our new plant with room to accept eight railcars at a time will give us unlimited reach and capacity to scale this business.”

When Green Energy Biofuel purchased the idled 40 MMgy plant, the facility came equipped with three 20,000-gallon biodiesel reactors. “We have left the three reactors and much of the process untouched for a reason,” Renwick said. “I know the day will come when fuel prices will rise to $4 per gallon and maybe if RIN prices increase, or other incentives were offered again, we could flip the switch and go right into biodiesel production. We have added five centrifuges to this process and still have two massive distillation towers and all the bells and whistles required to crank out millions of gallons per year—when the time is right. The best part is, with the extensive process redesign, we are able to process our own feedstock in-house for the lowest cost of biodiesel production than any plant I know of.”

Renwick added that Green Energy Biofuel is in negotiations to lease out some of its Warrenville acreage to another company that is interested in building a brown grease biodiesel production facility.

When asked whether it was time to change his name from “Bio” Joe to “UCO” Joe, given the company’s regeared focus on feedstock purification and sales, Renwick emphatically said, “No, I am still very much in the biofuel game. The reality is we make a way bigger impact supplying biofuel feedstock to both mid- and large-scale plants, which is exactly what they need—high-quality feedstock made by people that know what it takes to run a biodiesel process. Most importantly, we do it without all the [shenanigans] that some in the grease business provide. Grease suppliers have plagued this industry for years, ripping off companies with bad product or often never even delivering and just taking the money and running. It is funny how if you just do what you say you are going to do consistently, you can be successful. The Citadel Military College instilled in me values, honor and integrity. ‘You don’t lie, cheat or steal, or tolerate those that do.’ There are no shortcuts in business or life. With 10 years of hard work, blood, sweat and tears, I have branded ‘Bio’ Joe as someone you can work with in this crazy industry with confidence. And that won’t change.”

In late September, U.S. Representative Ralph Norman of South Carolina’s 5th District toured Green Energy Biofuel’s plant in Winnsboro in advance of National Clean Energy Week Sept. 24-28. The congressman was welcomed by Renwick and his wife and business partner Beth Renwick—a recent recipient of the Columbia Business Report’s 2018 South Carolina Women of Influence Award—along with plant manager Jack Sidlo and the Winnsboro team. During the tour, Renwick shared the hardships of the biodiesel industry with Norman as well as the determination that fueled him through the grueling years to get Green Energy Biofuel not only operational but successful. Afterwards, Renwick and the congressman imbibed in a shot of biodiesel to demonstrate the fuel’s safety and low environmental impact.

‘Next Gen Scientists for Biodiesel’ program selects 2 new leaders


Shyam Paudel’s interest in energy comes from deep in his childhood, growing up in the mountains of Western Nepal. Children commonly studied by the light of kerosene lamps.

“One summer, my father bought two solar panels for the house,” Paudel said. “After that, I never had to study under the dim, irritating haze of a kerosene lamp again. Even as a middle school boy, I recognized the power of this change, and my desire to end energy poverty was born.”

Paudel, a chemical engineering Ph.D. candidate at Missouri University of Science and Technology, is one of two new co-chairs selected to lead the Next Generation Scientists for Biodiesel.

The National Biodiesel Board program for college-level science students is intended to foster professional relationships between budding and established scientists, share accurate information and increase collaboration with academia and the biodiesel industry.

William Gray, a chemical engineering undergrad at Rowan University in Glassboro, New Jersey, will also provide student leadership for the organization. Gray’s journey with biodiesel began in the summer of 2017, with a research project that involved developing a feasible lipid extraction process for microalgae.

“I learned about the struggles holding back algae as a biodiesel feedstock,” Gray said. “We found that many issues arise due to the high cost of extracting out the lipids. Our lab’s work aimed to lower this cost, and hopefully will help bring algae back to the forefront as a practical energy source.”

Both men plan to attend an invitation-only Biodiesel Sustainability Workshop sponsored by the National Biodiesel Foundation in September. They have also attended the National Biodiesel Conference & Expo in previous years on scholarships set up through the NGSB program. The scholarship application process for the 2019 conference will open in October.

Paudel and Gray join one other sitting co-chair of the organization—Jennifer Greenstein, North Carolina State University, studying plant and microbial biology. A fourth co-chair, James Brizendine, recently graduated from Missouri University of Science and Technology with a degree in environmental engineering.

Made from an increasingly diverse mix of resources such as recycled cooking oil, soybean oil and animal fats, biodiesel is a renewable, clean-burning diesel replacement that can be used in existing diesel engines without modification. It is the nation’s first domestically produced, commercially available advanced biofuel. NBB is the U.S. trade association representing the entire biodiesel value chain, including producers, feedstock suppliers, and fuel distributors, as well as the U.S. renewable diesel industry.

Arkansas biologist receives grant to improve biofuel production

Waste Tyre Recycling Plant 0

A University of Arkansas biologist is developing methods that could make the production of biofuel—ethanol and diesel made from sources such as plant material—more efficient and environmentally sound. Ruben Michael Ceballos will use a protein derived from microorganisms that live in acidic geothermal pools and springs to enhance the process of turning organic material into fuel.

Ceballos, an assistant professor in the Department of Biological Sciences, recently received a four-year, $800,000 grant from the National Science Foundation for the research, which seeks to create a way to protect and enhance enzymes during the conversion process.

Most biofuel is produced using chemical catalysts, which creates issues of handling hazardous chemicals and managing hazardous waste. The use of enzymes, which are biological catalysts, is considered more environmentally sustainable, though it is often less efficient. Ceballos’ goal is to create a system that can enhance enzymatic efficiency in the high temperature and extreme pH conditions involved in the manufacturing of biofuels.

To do that, he is working with a protein derived from archaea, which are single-cell organisms that can exist in extreme environments including geothermal springs and pools.

“They basically live in boiling battery acid,” Ceballos said. “There are tools in nature that we can use in industries where enzyme-mediated reactions occur under harsh reaction conditions.”

Two other U of A researchers are involved in the project: Lauren Greenlee, an assistant professor of chemical engineering, who will help develop enzyme-recovery mechanisms; and Leandro Mozzoni, associate professor in crop, soil, and environmental sciences, who will help develop soybean and rice straw biomass to test reactions important in biofuels production.

“After working on the proof-of-concept for this biotechnology for the past several years, it is great to see that other scientists at the national level understand the value of this work,” Ceballos said. “We look forward to investigating and developing the system further so that it may be commercialized and offer significant enhancements to the biofuels sector, or any other industry where enzyme-mediated reactions under harsh conditions are essential for production processes.”
