After a decade of research, a little-known company based in Minnesota says it has developed a cheaper, more energy-efficient process to make biodiesel motor fuel from waste oils generated by commercial kitchens and the rendering industry.

Superior Process Technologies is a small research-and-development unit of privately held Baker Commodities, a large, family-owned renderer and waste grease recycler based in Vernon, Calif. Staffed by a handful of chemists and engineers, Superior Process has worked quietly in a small office and laboratory in northeast Minneapolis on a better way to refine grease, tallow and other waste oils into biodiesel.

Superior Process engineers Kirk Cobb and Joe Valdespino, whose innovations draw on decades of experience in the paper and oleochemical industries, now are working toward a big step: constructing a commercial-scale biodiesel refinery.

Baker Commodities plans next year to start building a 20-million-gallon-per-year biodiesel plant in Vernon, Calif., to recycle waste grease into fuel, said Doug Smith, general manager of Superior Process and assistant vice president for R&D at the parent company.

“Our process is superior to the traditional method,” said Valdespino in an interview at the company’s lab and office on NE. Broadway. “It saves energy. It increases yield. … It enables you to use cheaper feedstocks.”

The cheap feedstocks include used deep-fryer oils, rendered animal fats and the contents of grease traps in sewer lines. These waste products, often known as yellow or brown grease, are less expensive than soybean oil, the traditional raw material for biodiesel.

The challenge of converting waste into something useful appealed to Cobb and Valdespino. They met more than two decades ago while working as engineers for Union Camp Corp., a Savannah, Ga., paper company acquired in 1998 by a larger rival. The pine used in pulpmaking generated liquid rosin or tall oil, and the two engineers worked on ways to turn it into profitable products.

A different process

Minnesota, the nation’s No. 3 soybean producer, is home to other pioneers in the biodiesel industry, and has two large and one small biodiesel refineries owned by other companies. Under Minnesota law, the fuel is blended with petroleum-based diesel at rates of 5 or 10 percent.

Superior Process’ work on the biofuel has happened under the radar until now. Cobb first turned his attention to biodiesel in the early 2000s, joining Superior Process in 2004, moving to Minnesota a year later and hiring Valdespino in 2007.

Many of the nation’s 94 biodiesel plants don’t try to refine waste oils. Those that do typically rely on a pretreatment process — known as acid esterification — that uses sulfuric acid to remove free fatty acids that otherwise would interfere with the making of biodiesel.

“The traditional acid esterification process is really messy,” said Valdespino. “It is limited to very small free fatty acid impurities. It is very limited.”

The traditional process also causes water to contaminate another compound, methanol, used in the making of biodiesel. Cobb said the water then must be removed before processing oils into biodiesel, a step that takes more energy.

For years, Cobb and Valdespino have been working on a different process to address this challenge. It relies on heat and glycerin to modify free fatty acids into feedstock that can be refined into biodiesel. The process, called glycerolysis, is not new, and a version of it is employed by at least three U.S. biodiesel plants.

The Minnesota engineers say their process will refine the most challenging of waste oils. They added some proprietary features to the multistep biodiesel refining process, and have done all the engineering work to build a commercial-sized plant.

Challenging environment

The biodiesel industry has faced on-again, off-again federal tax incentives for the low-carbon biofuel. A $1-per-gallon tax credit for biodiesel expired last year. That has happened before, only to have the credit retroactively revived.

For now, at least, new plants like the one Superior Process wants to build won’t get the tax credit that helped earlier biodiesel start-ups.

Skepticism of the technology also can be a problem. In 2012, Cobb read an article in an industry journal declaring the traditional pretreatment process for waste oil more energy-efficient than the glycerolysis method championed by Superior Process.

Cobb pushed back with his own data, reporting that the opposite is true. Cobb said skeptics flagged on the fact that glycerolysis relies on higher temperatures, while ignoring how much energy is wasted to strip away water in the acid-based method.

“People misconstrue higher temperature with higher energy use,” Cobb said. “That is not the case.”

Cobb and Valdespino are excited that their ideas are headed toward commercial deployment.

The strategy, said Smith, is to get one plant up and running and showcase the technology. Then the company could go on to build other plants, or possibly license the technology to other companies, he said.

“It is going to be much lower cost; less than $2 per gallon,” Smith added.

The Minnesota ethanol industry is evolving even in the face of growth challenges including continued uncertainty around the Renewable Fuel Standard (RFS). Since 2007 the industry has improved by leaps and bounds in terms of technological advancements, energy efficiency and sustainability.

“Minnesota ethanol producers are continually evolving with respect to the use of technology and processes to decrease the inputs of energy and water while increasing their output of ethanol and co-products such as DDGs and corn oil,” explains Tim Rudnicki, executive director of the Minnesota Bio-Fuels Association.

According to a 2011 report from the Argonne National Laboratory, ethanol producers have cut water use in half within a 10-year period. In fact, Rudnicki notes that some producers are using less than two gallons of water to produce 1 gallon of ethanol. When comparing water use with the production of oil, depending on where the oil is extracted, oil production can require more than seven times that much water to produce one gallon of gas. Other ways ethanol producers are infusing sustainability within water use is by using storm water and treated municipal wastewater.

Specifically, the Al-Corn Clean Fuel ethanol plant has completely eliminated any process water discharge. Randall Doyal CEO of the Claremont, Minnesota-based plant says, “This cut our water consumption down to just over two gallons per gallon of ethanol. The water that is used is for cooling and is evaporated, so it returns to the atmosphere to recycle back as rain. We continually recover water in the process to reuse again and again.”

In other terms of sustainability, biofuels also offer a significant reduction in greenhouse gas emissions (GHG). When using Argonne’s Wells to Wheels methodology, total lifecycle GHG reductions for corn-based ethanol equates to a 57 percent reduction in GHS emissions when compared to petroleum.

“Biofuel producers are decreasing their inputs, increasing the outputs and providing consumers with a lower carbon renewable fuel that helps to reduce GHG emissions,” says Rudnicki.

Energy efficiency is also an area that has seen great improvements over the past few years. Doyal highlights the ingenuity of the ethanol industry when developing solutions to improve aspects of production.

“The ethanol industry has always been made up of people who constantly challenge the norm and try to find better ways to do things,” Doyal explains. This is very evident in how much we have seen energy consumption drop over the years. Our plant in Claremont was constructed in 1996 and over our history we have reduced both our natural gas and electricity consumption by over a third. Our results are fairly consistent with the industry as a whole. We have added thermal oxidation to reduce emissions from our feed drying process, and have integrated that into our operations to gain greater efficiency.”

Doyal says his plant, like many others have added distillers’ corn oil recovery, adding a new and valuable product line to their list of co-products. His team continually reviews new technologies to determine if they can further enhance efficiencies or add a new co-product.

His plant makes use of the advances in enzyme technologies and his team is always trying to push their yield of ethanol per bushel. “All of these adaptations provide our industry with greater sustainability,” stresses Doyal. “Couple this with the vast improvements in corn farming technologies and you can see how great the gains actually are. Farmers in our area are accustomed to achieving 200 bushels per acre or more, with lower inputs and chemicals while using more sustainable farming techniques. The impact of farm equipment technology in reducing fuel consumption while also reducing seed, chemical and fertilizer inputs pushes the efficiency even higher.”

On Monday we’ll hear from Doyal and Rudnicki on the what the next five years might bring for renewable fuels in Minnesota.

The United Nations climate change conference in Lima, Peru (COP 2014) should adopt policies to increase the use of biofuels like ethanol to reduce global greenhouse gas (GHG) emissions, said the Global Renewable Fuels Alliance (GRFA).

It said in a statement Dec 9 that biofuels are one of the most commerically viable solutions to reducing GHG emissions in the transport sector.

GRFA said 25 percent to 30 percent of all global GHG emissions come from the transportation sector. As such, it said the ongoing COP 2014 conference in Lima should adopt policies that include the increased use of biofuels.

GRFA is an international federation that represents 60 percent of the world's renewable fuels production from 30 different countries.

"Nearly a third of global GHGs comes from the transportation sector, those GHGs need to be a priority if we are going to make a significant contribution to combating climate change. Biofuels must be an integral part of that fight," said Bliss Baker, spokesperson for GRFA.

The GRFA said biofuels like ethanol have been proven to reduce GHG emissions from 40 percent to 90 percent in comparison to fossil fuels.

GRFA said it had forecast global ethanol production in 2014 to reach 90.38 billion liters (23.87 billion gallons) and its use would reduce global GHG emissions by over 106 million metric tons. This in turn, it said, was the equivalent of removing over 21 million cars from the road annually.

"106 million (metric tons) is a substantial GHG savings, it's the same as removing the annual emissions from 14 average-size coal-fired power plants. However, as the IEA (International Energy Agency) has prescribed recently, more biofuels are needed to further reduce the emissions from the global transport sector," said Baker.

GRFA said the IEA's "Technology Roadmap : Biofuels for Transport" report states "by 2050, biofuels could provide 27 percent of total transport fuel" and the use of biofuels would provide one fifth of emission reductions in the transport sector.

"It's clear that today, biofuels like ethanol, are helping combat climate change but to reach their full potential requires enhanced biofuels-friendly policies. The outcome of COP 2014 must be the adoption of policies that increase biofuels use and reduce our reliance on fossil fuels," Baker added.

On Dec. 8, the Chicago City Council Committee on Finance passed an ordinance that would require filling stations within the city to supply E15. The measure now moves to the full city council for a hearing on Dec. 10.

“I’m very pleased this ordinance has such strong support within the Council and across Chicago,” said cosponsor Alderman Anthony Beale in a statement. “I look forward to the full council vote, and to giving Chicagoans a cleaner, less expensive option.”

Supporters of the bill delivered a petition with 7,673 signatures to the Dec. 8 meeting. If passed by the full city council, the ordinance would build on Chicago’s history of passing environmentally friendly proposals.

“Chicago has time and again led the country in taking action to clean the air. The City banned leaded gasoline in 1984, and we banned a variety of toxic gasoline additives in 2000,” said Beale. “This ordinance continues that tradition of environmental leadership and stewardship.”

Growth Energy CEO Tom Buis has commended the finance committee for its action, calling the vote a win for consumers and the environment.  

“Once again, Chicago displayed its leadership qualities and took an important step in helping clean up the air in Chicago by breaking up the near monopoly that oil companies have on the liquid fuels market. By advancing this ordinance, the Finance Committee has demonstrated that they are serious when it comes to reducing greenhouse gas emissions and toxic carcinogens in the air,” Buis said.  “Furthermore, they have displayed their resolve to ensure that Chicago motorists and other consumers have market access to a sustainable, cleaner burning, less expensive homegrown fuel that supports 73,156 Illinois jobs and generates $4.7 billion for the state’s economy. By moving to E15, Chicago can help create an additional 12,000 Illinois jobs that can’t be outsourced.”

Ron Lamberty, senior vice president of the American Coalition for Ethanol also spoke out to applaud the finance committee vote. “The city of Chicago has always been a leader when it comes to fuel. It was the first city in the United States to ban lead in gasoline, the first to choose ethanol over MTBE in reformulated gas, and this ordinance would make Chicago the first major city to guarantee drivers the choice of a lower cost, higher octane, clean E15 fuel.  It’s important to note that regular gas will still be available, drivers will simply gain the additional choice of E15,” he said. “We appreciate that the ordinance also includes reasonable exemptions for station owners. Only stations that are already equipped to handle E15 will be required to offer E15, meaning no added expense for the station and no added markup at the pump.”

Prior to the vote, Lamberty send a letter to members of the finance committee expressing his support for the ordinance. A full copy of that letter can be downloaded from the ACE website.

Novozymes has launched a new enzyme, trademarked Eversa, for the conversion of lower-grade oils, such as waste cooking oil or corn oil, into biodiesel meeting the same trade specifications as biodiesel created through traditional chemical processing.  

“The flexibility of the enzymatic biodiesel process creates new opportunities for ethanol producers to optimize revenues from extracted corn oil by making biodiesel on site while also accepting waste greases from their local community,” said Frederik Mejby, Novozymes marketing director, grain processing. “The process can be easily bolted onto the back end of their existing facility with minimal additional CAPEX.”

Traditional chemical processing of biodiesel has been most suited for oils from soybeans, palm or rapeseed that typically contain less than 0.5 percent free fatty acids (FFA). Many existing biodiesel process designs have difficulty handling oils with higher FFA levels, even though those feedstocks are generally far more economical. “A small number of plants have been producing biodiesel from waste oils using existing technologies,” Mejby explained. “But this has not been cost-efficient until now, broadly speaking, as the waste oils have had to be refined before being processed using chemicals. We hope that our technology can unleash more of the potential in these lower-grade feedstocks.”

“The idea of enzymatic biodiesel is not new, but the costs involved have been too high for commercial viability,” Mejlby added. “Eversa changes this and enables biodiesel producers to finally work with waste oils and enjoy feedstock flexibility to avoid the pinch of volatile pricing.” Eversa works with a broad range of fatty materials as feedstock, but the initial focus has been on used cooking oil, DDGS corn oil and fatty acid distillates.

Other advantages for the enzymatic process include a lower energy requirement and the elimination of the chemical catalyst, sodium methoxide, one of the most hazardous chemicals in traditional biodiesel plants. “Switching to Eversa can lead to a safer working environment for plant operators. The enzymatic process does not use high pressure or high temperature,” Mejlby said. “And when it comes to the actual enzymes, their organic nature and mild process conditions do not generate toxic components as in some chemical biodiesel processes.”

For existing biodiesel producers, making the change from a chemical catalyst to the enzymatic process will require retrofitting. Novozymes’ engineering partners estimate that the resulting improved process economy indicates a payback time of three years or less, depending on the plant setup and feedstock savings potential in that region.

Marc Kellens, group technical director at biodiesel technology provider Desmet Ballestra said the enzymatic processing will likely prove popular with biodiesel producers. “The enzymatic process is simple and does not need much pretreatment. It is the best alternative for modifying existing plants to enable them to incorporate difficult-to-convert oils.”

A new approach to driving down the carbon intensity of corn ethanol has received approval from the British Columbia Ministry of Energy and Mines. Three pathways from Trestle Energy LLC were given approved carbon intensities of 29.10, 29.68 and 35.66 grams CO2 equivalent per megajoule (CO2e/MJ). That compares with an average rating of 55 CO2e/MJ for the 15 Midwestern ethanol producers who have received carbon intensity ratings under British Columbia’s Renewable and Low Carbon Fuel Requirements Regulation. And, it favorably compares with the 33.31 CO2e/MJ carbon intensity rating given to Peruvian sugarcane-ethanol producer, Maple Biocombustibles.

“We think of ourselves as a bolt on option for virtually any ethanol plant in North America,” Trestle Energy president Jamie Rhodes told Ethanol Producer Magazine.  “The approval from British Columbia is great because it validates the proposal of reducing greenhouse gas emissions in the agriculture sector that’s supplying feedstock.”

Rhodes explained that Trestle Energy has worked on the approach for several years, and demonstrated it in a partnership with a Midwestern ethanol plant.  “We worked upstream in their supply chain and demonstrated our ability to drive down emissions and the interest in the agricultural sector to participate in that. It was very successful across the board,” he said.

The British Columbia approval clears the way for Trestle to begin selling its low-emissions biofuel in the province, and the company will now begin partnering with existing ethanol plants in Iowa, Minnesota and across the Midwest to ramp up production of its low-carbon biofuels.

Rhodes, who is based in California, declined to give details on the approach at this time, but did give a high-level overview. “We looked at lifecycle analysis for biofuels and it seemed liked there was a lot of leverage to be had in the agricultural sector. That’s where we focused our efforts in the last few years. How do we demonstrably drive down emissions there to affect the lifecycle?  We developed a number of strategies that can be used in the agricultural sector and those emissions benefits flow down through the ethanol plants and to the ethanol product.”

The company has a pathway petition pending with the U.S. EPA and has applied with the California Air Resources Board for a carbon intensity rating under the Low Carbon Fuel Standard. Rhodes added that how Trestle Energy proceeds with commercialization may be affected by those regulatory decisions.

The Feed Food Fairness Campaign, backed by members of the livestock and fast food industries, recently ran a one-sided advertisement in the popular Beltway publication “Politico” inaccurately blaming the renewable fuel standard (RFS) for rising food prices. Bob Dinneen, president and CEO of the Renewable Fuels Association, fired back with the following statement:

“Never before in the history of misleading advertising has so much bull been slung in defense of chickens, hamburgers, and even potatoes. The ad is replete with misinformation. One would have to be awfully creative, for example, to draw any connection between biofuels and potatoes!

“Apparently, the Feed Food Fairness campaign is not big on facts or transparency. Their ad conveniently leaves out the key fact that their numbers come from a 2012 study on commodity costs during the worst drought in 50 years.

“Simply put, the information is outdated and misleading. We are now well into 2014 and that drought has long since subsided. Farmers are harvesting the largest corn crop in history. Corn prices have plummeted with this record crop and yet as a recent RFA study demonstrates, food prices continue to rise. They should take an ad out to explain that!

“Numerous independent analyses have concluded the RFS does not drive food prices—energy does. As noted by the World Bank, ‘most of the food price increases are accounted for by crude oil prices.’

“The market has drastically changed since the drought in 2012 and yet the livestock and fast food industries’ talking points have remained the same. The Feed Food Fairness campaign advertisement does a disservice to consumers everywhere.”

The biofuels industry is gearing up for a fight, a national industry spokesman said Monday.

Doug Durante, executive director of Bethesda, Maryland-based Clean Fuels Development Coalition, predicted lawsuits over the Environmental Protection Agency’s handling of quotas for renewable fuels and a hostile post-election U.S. Congress.

“The outgoing chair, Barbara Boxer, says global warming is the biggest threat facing mankind," Durante said of the California Democrat who chairs the Senate Environment and Public Works Committee. "The incoming chairman (James Inhofe, R-Okla.) says it is the greatest hoax that was perpetrated on mankind.”

Speaking at a Nebraska Ethanol Board meeting, Durante said several members of Congress are looking for a fight, including bills that would dismantle the United State’s renewable fuel standards.

“Our best bet is to pray for what Congress does best, which is nothing,” he said.

The Environmental Protection Agency’s struggle to set rules for mandating how much ethanol, biodiesel and cellulosic fuels get mixed into the nation's fuel supply only stoked the flames of discontent, he said.

Oil company lobbyists, who generally oppose the law that mandates replacing petroleum products with biofuels, are pressing Congress to dump the standards entirely, saying the EPA has bungled management of the program.

Already almost a year late in issuing rules, the EPA announced last week it would not finalize the 2014 mandates under the Renewable Fuel Standard this year. Instead it will set the final volume standards in 2015, and hopes at that time to get back on schedule to propose blending volumes for 2015 and 2016. Federal law requires the agency to finish up the requirements by Nov. 30 for the following year.

Nebraska is the No. 2 ethanol producing state in the nation, with 24 plants churning out 2 billion gallons a year. Nebraska Ethanol Board Administrator Todd Sneller has repeatedly called for the EPA to uphold strong renewable fuel volume requirements.

He said the proposed reductions in biofuel use impedes expansion of domestically produced renewable fuels that mitigate the harmful effects of petroleum on public health, the environment and the economy.

"Consumers deserve a wider variety of transportation fuel choices, including E15 and E85," Sneller said in a recent news release. "The RFS was intended to ensure choices are available to consumers. Oil companies have an obligation to meet these fuel standards.”

Nearly a year ago, the EPA proposed lowering the amount of advanced biofuels and renewable fuels, like corn ethanol and biodiesel, required to be mixed into the nation’s fuel supply for 2014 from just more than 18 billion gallons to about 15 billion gallons.

Durante said the biofuels industry needs to fight back against efforts to reduce mandates with lawsuits, if necessary.
