Ethanol Report on RFA CEO at Farm Progress Show

Ethanol Report PodcastThis edition of “The Ethanol Report” features an interview with Renewable Fuels Association President and CEO Bob Dinneen during a visit to the 2009 Farm Progress Show in Decatur, Illinois on September 2. Dinneen discusses the need to increase the amount of ethanol allowed in gasoline above the current 10 percent, the Environmental Protection Agency rulemaking on the expanded Renewable Fuels Standard and the issue of indirect land use, and the ability of American farmers to continue to produce enough corn to meet the demand for ethanol.

Ethanol Supporters Urged to Comment on RFS2

choose ethanol 18 daysThe clock is ticking down on the comment period for the expanded Renewable Fuels Standard, better known as RFS2. The Environmental Protection Agency will be taking comments until September 25th – just 18 days from now.

Bob Dinneen, president and CEO of the Renewable Fuels Association (RFA) is urging ethanol supporters to make their voices heard now on this important issue. “I am concerned that (the EPA) get this regulation implemented right,” Dinneen said during an interview last week at Farm Progress Show. “This is the first time the agency has been tasked with the responsibility of determining the carbon footprint of an industry and they are learning that’s not an easy thing to do and there is no scientific consensus to do it.”

Choose EthanolDinneen calls the principal of indirect land use being considered by the EPA “not just not scientifically sound, but silly” because it literally equates an acre of land used to grow ethanol in the United States with an acre of Brazilian land forest being destroyed. “This is a very big issue and we’re a long way from having it resolved.”

RFA has provided a simple way for people to make comments to the agency through an online advocacy tool at the website ChooseEthanol.com. Comments need to be received by EPA no later than September 25, 2009.

Studying New Feedstocks for Biofuels

The “World’s Largest Urban Farm and Research Test Facility” is studying a wide variety of new feedstocks that hold promise for future sources of both ethanol and biodiesel.

bioworksAgricenter International recently offered a closer look at the new crops being grown there by the Memphis Bioworks Foundation AgBioworks program and BioDimensions, Inc. Among the crops that were planted this season were sweet sorghum (pictured), switchgrass, castor, pearl millet and sunflowers.

“Our intent with hosting this new crops field day was to educate people on the opportunities for these crops in the region by inviting a range of speakers to talk about crops from the field to the factory and also showcase these crops in the field, “ says Hillary Spain, AgBioworks 25Farmer Network Coordinator.

Spain says about 50 farmers and other interested individuals from throughout the region attended the field day on August 15 to learn about each crop, ask questions and see the crop under actual growing conditions in the field.

EPA Officials Visit Iowa Biofuels Plant

EPA officials visit REG with Sen GrassleySenator Chuck Grassley (R-IA) hosted officials from the Environmental Protection Agency last week for a tour of agriculture and biofuels in Iowa. Gina McCarthy, Assistant Administrator for the Office of Air and Radiation, and Margo Oge, Director of the Office of Transportation and Air Quality, represented EPA on the visit that included the BioCentury Research Farm in Boone, an Iowa family farm and the Renewable Energy Group‘s (REG) Central Iowa Energy plant in Newton, which included an overview and update from the ethanol and biodiesel industries.

“The EPA has tremendous power and authority, and the decisions it makes on several issues will have a major impact on the rural economy, from the family farm to opportunities in value-added agriculture industries, including renewable energy. It is absolutely essential that the government officials in charge understand the issues and the impact of their rules, regulations and directives,” Grassley said.

EPA is in the process of taking comments on implementation of the renewable fuels standard (RFS2) under the 2007 Energy Independence and Security Act. In their comments to EPA, REG chairman Jeff Stroburg said, “We firmly believe that the intent of policy makers and the administration to reduce our dependence on foreign petroleum supplies, support American agriculture, and reduce harmful greenhouse gas emission can be successfully achieved with the implementation of RFS2.”

Ex-CEO Arrested for Selling Illegal RINs

The former CEO of biofuel company American Bio-Fuels, based in Abbeville, Alabama, was arrested yesterday for selling illegal Renewable Identification Numbers (RINs). Arnesto, “Steve” Sobrado was charged with felony first-degree theft of property. American Bio-Fuels went out of business in June.

According to an article published by the Dothan Eagle, the charge was a result of a report made by an owner of American Bio-fuels in July that claimed Sobrado was selling illegal RINS to Paquin Energy & Fuel based in Keller, Texas. Sobrado allegedly sold $54, 915 worth of the fake RINS to Paquin Energy & Fuel in June and July.

RINs are 38-digit serial numbers assigned by biofuels producers to each gallon of fuel produced. They are used by the EPA to track that the gallons set forth in the Renewable Fuels Standard each year are met. This year, the mandate set the amount of biofuels to be blended at 11 billion gallons. Each RIN is priced on average at 10 cents, so more than $1 billion worth of RINs will be produced this year.

300_Logo_2“We have the safeguards and controls in place to prevent fraudulent acts like this for producers,” says Clayton McMartin, President of CFCH and founder of the RINSTAR(r) renewable fuel registry. “Through our system, we can safeguard our clients from receiving fraudulent RINs because our due diligence enables us to discover and reject them. Serious companies need to prevent this fraud.”

According to the EPA website, they have yet to issue a violation and I have contacted the agency for comment.

USDA Gives $13 Mil for Renewable Energy Projects

usda-logoThe USDA is handing out another $13 million in loans and grants for 233 renewable energy projects in rural areas of 38 different states.

The projects were announced in this press release and during a speech at the Farm Progress Show in Illinois, that included some of the highlighted projects:

The loan guarantees and grants can be used for renewable energy systems, energy efficiency improvements, feasibility studies and energy audits. These funds are not part of the American Recovery and Reinvestment Act.

In Story City, Iowa, Milford Wind Energy, LLC, has been selected to receive a $1.8 million guaranteed loan and a $500,000 grant to build a 900 kilowatt wind turbine for energy generation. When complete, the turbine is expected to produce nearly 3.3 million kilowatts of electricity annually and generate more than $200,000 in electricity that will be sold to the local utility company. Construction of the turbine is expected to be completed next year.

REAP funding is already contributing to increased renewable energy production. For example, in 2003, USDA Rural Development approved a $300,000 renewable energy grant to Lincolnland Agri-Energy, LLC., in Palestine, Ill. The 453-farmer cooperative operates a livestock feed production plant and a 49-million-gallon-per-year ethanol plant. The grant enabled the cooperative to by a $1.4 million thermal oxidizer to control plant emissions. This critical piece of equipment removes 75 percent of the emissions from the dryer exhaust without reducing plant performance. The oxidizer has another benefit: the heat it produces is captured in a steam recovery system and turned into energy. Lincolnland’s USDA grant produced 37 local jobs.

Nebraska Ethanol Industry Bounces Back

According to the Governors’ Biofuels Coalition (GBC), Nebraska’s ethanol industry has nearly recovered from the economic doldrums it faced last year and is back near full production capacity.

An important indicator that the ethanol industry is recovering, Todd Sneller said of the Nebraska Ethanol Board, is the “modest job increase” they saw in the ethanol industry while reviewing state ethanol data comparing 2008 to 2009.

ne-ethanol-brd“While overall it may only be a couple of dozen jobs on a statewide basis, it is an important signal because we were in a period of real economic turmoil in the ethanol sector, but yet we didn’t see layoffs in those plants, even the ones that went through bankruptcies, and in a couple of cases we saw companies use this time to modify their plants to create addition production capabilities, such as corn oil extraction,” Sneller said.

According to Sneller, during the last three to four months plants have been starting to operate much closer to their operational rate of capacity, so if they were operating at 70 percent to 80 percent of capacity, they are now operating “much closer to 100 percent of capacity.”

Ethanol Production Numbers Announced for June ’09

2006_07_11_Ethanol_Plant_lgU.S. ethanol production is on the rise with the news that the industry has set new production records. According to the Energy Information Administration (EIA), American ethanol facilities produced 694,000 barrels per day (b/d) in June 2009. That is up 109,000 b/d from a year ago.

Ethanol demand, as calculated by the Renewable Fuels Association (RFA), continues to outpace production. According to RFA calculations, demand was 721,000 b/d in June, up from 633,000 b/d a year ago. EIA also reports fuel ethanol imports of 29.5 million gallons in June.

The RFA released the following statistics:

June 2009 Statistics (mg = million gallons; b/d = barrels per day)

Fuel Ethanol Production: 874.5 mg / 694,000 b/d
Fuel Ethanol Use: 904.0 mg / 721,000 b/d
Fuel Ethanol Stocks: 583.9 mg / 19.3 days of reserve
Fuel Ethanol Exports: 0.0 mg
Fuel Ethanol Imports: 29.5 mg

Ethanol in Focus at Farm Progress Show

Illinois EthanolEverywhere you go at the 2009 Farm Progress Show in Decatur, Illinois this week, people are talking about ethanol.

Over at the corn grower tent marked by 30+ foot high corn stalks and an E85 blimp hovering overhead, they have information about how the carbon footprint of corn production has declined substantially in recent years and they are encouraging farmers to submit comments to Environmental Protection Agency about the Renewable Fuel Standard.

Bob DinneenRenewable Fuels Association president and CEO Bob Dinneen toured the Farm Progress Show on Wednesday and was able to visit many of the exhibits, talk with farmers and do interviews with agricultural media representatives. Dinneen says most of the corn growers are telling him the crop looks very good this year. “I wish that there were more policy makers, government officials, regulators here at this event to see how much progress has been made and see what modern agriculture is all about,” said Dinneen. “This is not your grandfather’s farm anymore!” He says with the second largest corn crop on record expected to be harvested this year, American farmers continue to prove that they can produce enough corn to make ethanol and feed the world as well.

Grassley to Host EPA Officials at Iowa Biodiesel Plant

grassley3U.S. Sen. Chuck Grassley (R-Iowa) will play host to a pair of EPA officials at an Iowa biodiesel plant this coming Thursday at 3 pm. Let’s hope he can use the opportunity to teach them the REAL math behind the amount of corn and soybeans it takes to make ethanol and biodiesel.

This story from Biodiesel Magazine
says Grassley will talk biofuels at the 30-million-gallon-a-year Central Iowa Energy biodiesel plant in Newton, Iowa with EPA assistant administrator of the Office of Air and Radiation, Gina McCarthy, and EPA director of the Office of Transportation and Air Quality, Margo Oge, who will also visit a family farm and agricultural businesses:

The purpose of Grassley’s invitation was to highlight how EPA policies and regulations impact his constituents in Iowa. Jeff Stroburg, CEO and chairman of Renewable Energy Group Inc., the plant’s managing company, and others in the business will discuss the proposed RFS2 ruling with the senator and two EPA officials.

Many in the industry are calling on EPA to install interim rules to trigger the biomass-based diesel volume requirements sooner rather than later, and to reconsider how the agency negatively views soy-based biodiesel in its faulty indirect land use assumptions.

As you might remember… and you can see in the clip below… Oge is the goofus who believes that it takes 64 acres of corn to make one gallon of ethanol and 400 acres of soybeans for each gallon of biodiesel. Actually, one acre of soybeans makes 64 gallons of biodiesel and one acre of corn makes over 400 gallons of ethanol. And these are the folks deciding Indirect Land Use formulas? Let’s hope Grassley sets her straight.

Construction to Start on Southern California Ethanol Hub

A Houston-based company is starting work on a new ethanol transport hub in southern California.

"usdg"U.S. Development Group (USDG) will begin construction on the West Colton Rail Terminal, a new ethanol hub located in the Inland Empire area of southern California.

Construction of the facility will occur in two phases. The first phase, located in Rialto, Calif., will consist of a manifold transfer system that will begin receiving and offloading ethanol railcars in the fall of 2009. The second phase includes full unit train capability and ethanol storage. It will be located on an adjacent site in Colton, Calif., and is scheduled for completion in mid 2010. The Phase 1 facility will have the capacity to handle the current Colton area demand for ethanol plus that required to meet the 2010 mandated increase to a 10% blend.

“Demand for ethanol in southern California continues to grow in order to meet the requirements of the State’s biofuels mandates,” said Larry Padfield, vice president of U.S. Development Group. “Our new facility will help meet this growing need for ethanol by greatly enhancing the distribution capability of ethanol in the region.”

Extended families of the ’90s.(different ways of child care in families)

Ebony November 1, 1996 | Townsel, Lisa Jones First lady Hillary Rodham Clinton re-popularized the notion. But for centuries, Black people have acknowledged and embraced the concept of the village.

Before the advent of welfare, nursing homes and day-care centers, the extended Black family attended to virtually every need of the African-American community. Homes served as hostels, kitchens as diners, bedrooms as birthing areas – and neighbors saw to it that every child was well taken care of But migration, urbanization, unemployment and revolutionary institutional changes have severely changed the structure and the function of the family unit – Black and White – and redefined family life as we know it, perhaps forever.

“Families are still the centerpieces of African-American life, but they have clearly changed and evolved quite significantly over the past century,” says Dr. Niara Sudarkasa, president of Lincoln University (Pa.) and a noted author and anthropologist.

Consequently, Dr. Sudarkasa and other social science experts say an increasing number of young professional couples have had to make some tough choices. Although some have left their home base for promising jobs, many have found that they also left behind grandparents, aunts, uncles, nieces and nephews – relatives who have historically assisted young families with child care. go to web site lincoln university pa

“We’ve got nuclear families, but we don’t get into much of the extended families anymore,” notes Dr. Anna Harvin Grant, head of the sociology department of Morehouse College and director of the Family Institute in Atlanta. “I wish we would embrace the village concept, whether it is biological, legal or just reaching out to the extended family of friends and relatives. Somehow, we have to come back to a sense of caring. Otherwise, the human race is going the way of the dinosaur.” A number of young couples, like Kimberly and Darren Carter of Kansas City, Mo., don’t plan to let that happen. They still live and work in areas where they have strong family structures in place. But many others, like Gail and David Howard of Fairfax, Va., do not live in areas where they have much family, which makes it necessary for them to bear the brunt of child-rearing responsibilities alone. Yet in other cases couples like Tracy and Sonia McMillan of Arlington Heights, Ill., who do not have family nearby, have created extended family networks among trusted friends for support.

The idea of incorporating friendship ties into the extended family structure is not new, social experts say: “The extended family always extended to people who often weren’t blood relatives,” says Dr. Robert B. Hill, director of the Institute for Urban Research at Morgan State University and author of several books on the subject. “So many people whose blood relatives lived far away developed relationships with close friends who provided interchanging support, extended family support.

“We need to take that concept of `It takes a village…’ seriously,” Dr. Hill says. “I’m optimistic that things can be positive. But it means we will have to work together to make that happen.” Kimberly Carter, a specialty editorial manager at Hallmark Cards Inc., readily admits that neither she nor her husband, Darren, a 29-year-old plant controller, gave much thought to having family Close by when they married and moved to his hometown of Kansas City, Mo., after college. But now, the 29-year-old mother, who has a 9-month-old son, says she couldn’t imagine how drastically different their lives would be if they didn’t have close family around to help out.

“I didn’t realize that [family support] needed to be considered until after I had Isaiah,” the new mother says. “You know that saying, `it takes a village to raise a child,’ I really believe that is true because I don’t know that you can ever anticipate the emotional, financial and time drain that a child has on you.” Neither Carter nor her husband could have anticipated that just a week after she returned to work that their son’s baby-sitter would quit. Immediately, the Carters were in need of familial support.

“I had been at work a week trying to get re-established, and then I had to deal with this crisis,” Carter says, exasperated. “I have a pretty busy schedule; it’s pretty hectic as a manager. And it was difficult trying to find a baby-sitter over the phone, so I took off a few days to interview child-care providers and to make sure that I was making the right choice about who to leave my son with. But in the interim, my mother and father-in-law kept the baby for me. That kept me peaceful and focused at work because I knew he was with people we trusted. That was a tremendous help.” Without regular assistance from relatives and church members, Carter says she and her husband would always be in crunch. “I make a lot of long distance calls to my own mother and sisters for advice,” says Kimberly Carter, who is from Memphis. “But it’s really great to have people here in town who love our son. Having family close by gives us a break as parents, and it helps us to maintain our relationship as a couple. If on a Saturday I need to go to the grocery store, I can drop him off. I can just call [family members] up and they always like to see him. So I don’t feel like I’m imposing.” The best part about having a support system, Carter says, is that it gives her and her husband peace of mind. “It’s good to know that if you’re in a pinch, you don’t have to be nervous all the time that something is going to happen and you’re going to have to try to find somebody [to watch your child]. Since I have close relatives and church members in town, if a crisis arose, I would have someone to keep him. I wouldn’t have to feel guilty or stressed. It makes things easier to know they’re there.” Gail Smith-Howard and her husband, David, who are parents to a 2-year-old son, live hours away from most of their kith and kin. During the first year of their son Daniyyel’s life, the Howard treated child-rearing like a business partnership. David Howard, a 38-year-old, self-employed carpet broker who works from a home office, watches the toddler during the day. His wife, a hotel general manager, tends to the baby’s needs in the evenings and on weekends. (This year, the Howards say, things may change, since Daniyyel will attend day care.) “All marriages have to be a partnership. We’re both two independently successful people, and we have to support each other: We’ve been very blessed so far because a lot of the [child-rearing responsibilities] fall on us,” says 39-year old Smith-Howard, who is from Montclair, N. J. Her husband’s family is spread across Kansas, New Mexico and California. “We’ve always been committed to taking care of Daniyyel.” But the Howards say their schedules haven’t always been in sync, like the time when Smith-Howard was at the hotel preparing for a special promotions campaign while her husband, at the home office, had just received word of a lucrative business deal that be needed to respond to in person. That meant, Smith-Howard explains, that someone needed to watch their son – right away. Luckily, she says, a friend from Maryland was in the area and able to baby-sit. web site lincoln university pa

“We worked it out. But that’s tough,” she says. “It’s times like that that we wonder what we would do if my friend or one of my two cousins [who live in the area] weren’t around.” One saving grace, Smith-Howard says, is that every other month, her mother travels from New Jersey to Virginia to watch the toddler for a week or so, which gives her and her husband a little time to themselves. “It’s like a date; you get excited about it and it really keeps your relationship fresh,” she says of those rare occasions.

It took Tracy and Sonia McMillan of Arlington Heights, Ill., years to find trusted child-care help and almost that long to get some time to themselves. Three years ago, the McMillans, who have two young daughters, ages 3 and 5 months, moved to the Chicago area, where neither of them has family.

“We knew we weren’t going to have any family here, and that was almost a deal-breaker from my wife’s perspective,” says 32-year-old Tracy McMillan, a certified public accountant from Philadelphia.

McMillan’s wife nods in agreement. “It’s a lot easier when you have a family around to help out with the children; so we were concerned about what it would be like having children out here with no support,” says Sonia McMillan, whose family lives in New York and Barbados.

For a while, trying to secure trusted child-care help was a hit-or-miss situation, the McMillans say. “We have struggled,” laments the young father. “Not until recently have we found a niche in terms of finding outside baby-sitters. And, of course, you rely more so on your family and that puts your mind at ease. But we didn’t have that advantage when we came out here. So we had to do a lot of investigating and referral checks.” At one point, the McMillans, who both maintain breakneck work schedules, say they resorted to desperate measures in order to manage their child-care needs. “Once when we first moved here, we both had to be out of own at the same time, and that was a nightmare,” recalls 32-year-old Sonia McMillan, a software analyst. “We didn’t know anybody we could leave our children with overnight, so we ended up flying Tracy’s mother down to watch the kids for us.” The McMillans say they have no doubt that their lives at that time would have been much easier if their families lived nearby. “This past summer, I went home to New York, and it was really nice,” Sonia McMillan says. “The children were with my mom. And it was nice to be able to go places without having to worry about them. So it makes a big difference. If our families were here and we had more of a support system, we could do a lot more together.” Nevertheless, Sonia McMillan and her husband have learned to make the best of less-than-optimal circumstances. Over the past three years, they have developed strong friendship ties with a number of other young Black couples in their community. “A few times when we’ve been absolutely stuck, our friends baby-sat for us. And we’ve actually had a friend or two watch our older daughter overnight once or twice when I was out of town and Tracy needed to work late,” the native Barbadian says. “And sometimes we return the favor.” The McMillans, like so many other families who live far away from loved ones, wish they had family members nearby who could assist with the daily challenges of child care. But they say they are fortunate to have trusted friends they can rein, on. “If we weren’t comfortable, we wouldn’t leave our children with them – regardless of friendships,” Tracy McMillan contends. “But we’ve found a very sustainable network here, and that keeps us going.” If the extended family of the future is to survive, Dr. Sudarkasa says, the Black community as a whole has to recommit and pull closer together. “It is absolutely vital for us to return to [the extended family] for the basis of our self-help,” she says. “Whatever the extended family becomes as we move into the 21st century will be different than what it was in the past. But we have to build on our kinship and friendship ties if we are to succeed during the next century and the next millennium.” Townsel, Lisa Jones

Energy Grants $1.6 Mil for Public Education Efforts

DOEThe U.S. Department of Energy has handed out $1.6 million to the Alternative Fuel Trade Alliance… a group made up of the Renewable Fuels Association, the National Biodiesel Foundation, the Propane Education & Research Council, the Clean Vehicle Education Foundation and ASG Renaissance… to boost efforts for a targeted educational plan aimed at Clean Cities Coordinators and related stakeholders.

This NBB release says the move is seen as vital to educating and training “Clean Cities Coordinators who are and will be at the forefront of communicating what our fuels and vehicle technologies mean as engines of economic growth and environmental sustainability.”

dineenBob Dinneen, President and CEO of the Renewable Fuels Association, commented, “This DOE grant will supplement our individual and joint efforts to work with and train coordinators, stakeholders, and others at the national and regional level to enhance their knowledge and expertise on the latest developments and applications for alternative fuels and advanced vehicle technologies which include ethanol, biodiesel, propane, and natural gas fuels as well as hybrid/electric technologies and idle reduction strategies to improve fuel economy.”

joe-jobethumbnailJoe Jobe, CEO of the National Biodiesel Board, said “This program unites the mainstream alternative fuel organizations in working collaboratively towards a common goal: educating America on all aspects of alternative fuels, and increasing their use. This will benefit our air quality, our energy independence and our economy.”

According to the Alliance proposal, the grant funds will also be used to:

* Train coordinators as high-level public spokespeople;
* Increase awareness of sustainability as it pertains to the stated technologies;
* Increase the number of states that enforce fuel quality standards;
* Train key stakeholders on fire safety issues;
* Increase OEM technician/mechanic training and advanced technology acceptance;
* Provide a forum for students interested in alternative fuels on college campuses nationwide; and
* Increase the availability and consumption of domestic alternative fuels.

The Alliance will conduct more than 45 workshops, author a minimum of 20 educational pieces, and participate in a minimum of 64 collective independent stakeholder events. In addition, the group will manage two conferences and four press events to increase knowledge about alternative fuels and advanced vehicle technologies.

Melons Could Be the Next Great Ethanol Feedstock

watermelonWatermelons… that tasty summertime treat… could be the next feedstock for the green fuel ethanol.

We’ve told you previously about how the National Watermelon Association has been pushing the idea of the fruit being used for ethanol (see our posts from May 20, 2009 and January 7, 2008). Now, it looks like there’s some research to back up that idea.

Wayne W. Fish, Benny D. Bruton and Vincent M. Russo have published this paper in the latest edition of Biotechnology for Biofuels showing how the melons that aren’t good enough for grocery stores might be just fine for the gas pumps:

Two economic factors make watermelon worthy of consideration as a feedstock for ethanol biofuel production. First, about 20% of each annual watermelon crop is left in the field because of surface blemishes or because they are misshapen; currently these are lost to growers as a source of revenue. Second, the neutraceutical value of lycopene and L-citrulline obtained from watermelon is at a threshold whereby watermelon could serve as starting material to extract and manufacture these products. Processing of watermelons to produce lycopene and L-citrulline, yields a waste stream of watermelon juice at the rate of over 500 L/t of watermelons. Since watermelon juice contains 7 to 10% (w/v) directly fermentable sugars and 15 to 35 umol/ml of free amino acids, its potential as feedstock, diluent, and nitrogen supplement was investigated in fermentations to produce bioethanol.

The researchers concluded that the watermelon juice would have to be concentrated 2.5 to 3 times if it were to be the sole feedstock for ethanol. But it could be used with other more concentrated feedstocks.
