With March 18 designated as National Biodiesel Day, we checked in with Dr. Raj Shah, an expert in biofuels. Dr. Shah serves as the Director of Sales, Marketing, and Technical Services for Koehler Instrument Company. He is currently on the industrial advisory board at the engineering department of Hofstra University, NY, and also on the advisory board of State University of New York at Stony Brook, Department of Chemical Engineering. He is an active member of ASTM, STLE, NLGI, SAE, ACS, and AICHE and chairs subcommittees in several of these organizations. <\/em><\/p>\n

Q: Biofuels-related topics are abundant in today\u2019s news. From commercial airlines <\/strong>powering their jets with biofuel to the food vs fuel debate in biofuel production, the dialogue is both dynamic and passionate. What do you see as the significant issues in biofuels right now? <\/strong><\/p>\n

A: Most biofuel-related issues can be traced back to the source: feedstock (including vegetable oil). The cost of feedstock used to produce biodiesel is high due to limited availability. Aside from its use as an energy source, it is a primary source of food for human nutrition. This is the essence of the food vs fuel debate. A fraction of vegetable oil is available for nonfood use. With a limited supply of land for crops, a dilemma emerges as to how much can be used for biofuel production.<\/p>\n

\"\"<\/a>For years, the main argument against biofuels has been the cost of production. Biodiesel prices must remain low because they are linked to the diesel price with which it is blended. Meanwhile, feedstock used to produce biodiesel is also a globally traded commodity whose price is determined by the balance between supply and demand in the market. Demand for the commodity increases as more biodiesel production occurs, which in turn leads to shortages in supply. In order for the two to reach equilibrium, the price of feedstock is raised to lower the demand. This in turn increases the cost of production\u2014which is already criticized for being too high.<\/p>\n

Additionally, newer issues have emerged involving agrofuels, such as ethanol and biodiesel, which are manufactured from crops grown on a massive level to be used purely for biofuel. These agrofuels have been chastised not only for their negative impact on the price of food, but for other environmental reasons including their absorption, during production, of thousands of gallons of fresh water. Biofuel production from ethanol requires a greater quantity of water than gasoline. This high volume may increase the stress on water supplies in vulnerable areas of a producing country. The surge in corn production for the use of fuel has been blamed for the rising presence of air pollutants such as particulate matter, ozone, and sulfur oxides. Ethanol production has also contributed adversely to surface and ground water, with effects including eutrophication (an increase in supply of organic matter in an ecosystem), hypoxia (reduced oxygen level in a body of water), and harmful algal blooms.<\/p>\n

Finally, there is great uncertainty surrounding the effectiveness of biofuels in reducing greenhouse gases. Much depends on how the biofuels are produced and how the land is used. There is a good possibility that as a greater supply of ethanol is needed, uncultivated crop land will need to be cultivated. As a result, plants grown for the sole purpose of being cut down to produce fuel will replace naturally existing, carbon-dioxide-reducing plants. This will result in an increase in the quantity of carbon dioxide in our atmosphere.<\/p>\n

Underlying all of these biofuel production issues is the need to globally standardize testing for quality. Currently the United States has one set of standards, Europe has another, and so forth. Without a definitive worldwide common standard, the quality of a particular sample of biofuel may vacillate widely. This diversity is a challenge in producing and distributing biofuels worldwide. For the last few years, ASTM has worked to create common standards. This is still in progress but moving in the right direction.<\/p>\n

Q: What do you see happening on the international landscape with biofuels?<\/strong><\/p>\n

A: \u00a0The answer to this question depends on where we look in the world. Let us take the example of two different developing economies.<\/p>\n

India shows great promise in entering the biofuels market with the cultivation of the jatropha plant. Jatropha is a second generation biofuel which has the ability to be grown as an agrofuel. Jatropha is a \u201cwonder plant\u201d because it grows easily in India where no other plant product will grow. It is not eaten, so using it for biofuels does not take away from the food supply. Growing jatropha requires little maintenance. Yet the cost of producing jatropha-based biofuels is currently about twice as much as other sources. Finding a method of making commercially viable biofuels from jatropha is certainly an opportunity.<\/p>\n

And, considering that India has reasons to look for new sources of fuel, it seemingly is an opportunity that is welcome in India. Right now, the demand for crude oil in India is drastically rising as the country develops rapidly. Biofuels offer a sustainable source of energy for India and provide it with an opportunity to greatly reduce its global footprint.<\/p>\n

Internationally, the US and Brazil currently provide 80% of the world\u2019s ethanol. While the US produces corn-derived ethanol, Brazil makes ethanol from sugar cane. Sugar cane requires less land, less fossil fuels, has better climate benefits, and fewer environmental detriments. At the end of 2011, a US tariff on imported ethanol expired, opening up trade options. Because the cost of the tariff raised the price of the ethanol, the tariff elimination means that ethanol can now sell at market prices.<\/p>\n
