A government-sponsored biodiesel policy has been formulated in an effort to promote the biodiesel industry in India. The Ministry of Petroleum and Natural Gas declared a “biodiesel purchase policy” to realize the program for “enterprise-driven biodiesel production”.

Under the policy, public sector oil marketing companies in 20 biodiesel procurement centers throughout the country will purchase biodiesel (complying with the Indian Bureau of Standard Specifications) from registered biodiesel manufacturers. Priority will be given to biodiesel manufacturers which use non-edible oils as feedstock. The government has also plans for drawing up policies related to the blending of biodiesel with regular diesel (5% by 2012 and 10% by 2017) and the establishment of a minimum support price for Jatropha and other non-edible oilseeds.

Vietnam is set to advance its bioenergy program through the construction of two large ethanol production plants, each with different biofuel feedstocks. The first plant (to be constructed by Itochu Corporation , Japan) will utilize cassava chips and will have an estimated annual production capacity of 100 million liters. The second plant (to be constructed in partnership between Vietnam’s Bien Hoa Sugar Company and Singapore’s Fair Energy Asia Ltd) will have an annual ethanol production capacity of 50,000 tons.

According to the Biopact website, Vietnam has a large cassava production potential and can benefit from its utilization as a bioenergy feedstock. Cassava is reported to thrive in marginal soils, and requires low agricultural inputs. Studies have also found that cassava is an “efficient biofuel plant” due to its “strong energy balance”.

Dupont Company, with its collaborative energy-company partner, British Petroleum, BP, have announced the planned distribution and marketing of biobutanol-blended gasoline in the United Kingdom in the fall of this year. The initial blend will be 16% biobutanol to 84% gasoline. Touted as the “world’s first advanced biofuel”, biobutanol (or butanol produced from biomass) is a 4-carbon alcohol, which is reported to have advantages over ethanol (a 2-carbon alcohol) in terms of energy content and ease of distribution.

According to David Anton, DuPont venture manager for the project, biobutanol has 85% of the energy content of gasoline compared to ethanol’s 65%. It could also be easily distributed through existing pipelines, which is not the case for ethanol. The production technology can also be tailored to take in a variety of biomass feedstocks, including wheat, corn or sugarcane. According to Michelle Reardon, Dupont spokeswoman, “It’s going to provide new markets for key crops”.

Energy Crops and Feedstocks for Biofuels Production

A report by Reihardt Howeler, of the Cassava Office for Asia, International Center for Tropical Agriculture (CIAT), presents the potentials of cassava in Asia and the case for more research to realize these potentials. Cassava is said to be the “third most important food crop” in Southeast Asia, next to rice and maize. It is also an “orphan crop”, receiving lesser funding for research compared to rice and maize. Cassava is generally grown mainly by marginalized farmers.

However, this situation may soon change as cassava takes the spotlight as a major biofuel feedstock for ethanol production in Asia. Marginalized farmers are also set to benefit from this move. The report cites the case of Thailand, where a surplus production of the crop resulted from a sharp decrease in the demand for cassava pellets from the EU. Consequently, the country shifted its strategy from cassava-pellet processing, to cassava-starch processing (to supply domestic and export markets), and diversifying the use of cassava as feedstock for ethanol production. The present factory, producing 80,000 liters per day of cassava-ethanol, will soon be joined by at least 12 more, making a total daily production of 3.4 million liters of cassava ethanol per day. This translates to a crop requirement of 3.5 tonnes to 4.5 tonnes per rai (1 rai is about 1600 square meters).

Howeler cites the need for more research in breeding, agronomy and biotechnology to increase and realize crop production targets. In addition, research efforts are also needed to improve cassava processing technologies, together with “dynamic and effective extension programs using a farmer participatory approach”.

Scientists from the School of Food Engineering, State University of Campinas, Brazil have found a way to improve ethanol fermentation from sugar can molasses, by the application of “extremely low frequency” (ELF) magnetic fields. The fermenting microorganism is the yeast Saccharomyces cerevisiae, and the bioreactor system a “recycle loop”-stirred-tank-fermenter.

In the “recycle loop” bioreactor, the actively fermenting culture broth is continuously pumped out of the tank, then passed through a magnetic field (generated by an arrangement of magnets), and then returned back to the bioreactor. This application of ELF magnetic field results in an increase in the rate of ethanol production. Under the best operating conditions (recycle velocity of 0.9-1.2 meters/second and a magnetic field treatment of 20 milli-teslas plus solenoid), the volumetric ethanol productivity is increased by 17%.

Changes in membrane permeability and a redox system in the presence of an electromagnetic field are postulated to be the reasons for the positive effect on ethanol production. The magnetic treatment could shorten the ethanol fermentation time by about 2 hours, and can be “easily implemented on an industrial scale”. The details of their findings are published in the ACS (American Chemical Society) Publication, Biotechnology Progress (URL above).
