Oil Palm Plantations Expand on Degraded Land in Amazon

Brazil hopes to eventually become a major producer of palm oil, thanks to the expansion of this new exotic monoculture crop in the eastern Amazon jungle, where eucalyptus plantations are also mushrooming on broad swaths of already deforested land.

The northern Brazilian state of Pará is becoming the land of the African oil palm (Elaeis guineensis), after earning a reputation as the Amazon jungle state to lose the largest amount of native forest to agriculture, livestock, logging and the production of charcoal used in local iron foundries.

The biofuels subsidiary of Brazil’s state-owned oil giant Petrobras has set a goal of producing 420,000 tonnes a year of palm oil, double the country’s current output, with two projects in Pará. Seventy percent of the company’s production will go to Portugal, where it will be turned into biodiesel to supply Europe, in a partnership with the Portuguese state-run oil company Galp Energía.

The subsidiary, Petrobras Biocombustível, is planting oil palm on 6,000 hectares of land, and growing seedlings to cover a total of 74,000 hectares.

“Our focus is the growing biodiesel market,” despite the good prices paid by the food and cosmetics industries, Janio Rosa, Petrobras Biocombustível’s director of agricultural supplies, told IPS.

The Brazilian mining company Vale, the world’s largest producer and exporter of iron ore, launched a project in 2009 to produce 160,000 tonnes a year of biodiesel as of 2014, to reduce transportation costs in its railways and ports by switching from conventional diesel.

To that end the company, which was privatised in 1997, is planting 60,000 hectares of oil palm in six different areas of the state of Pará, where its main mineral reserves are located, in the Serra do Carajás.

But it will take Brazil many years to make significant headway into foreign markets. This year it produced a mere 0.5 percent of the world total of 46 million tonnes. And it takes oil palms three years to begin to produce fruit, and eight years to reach full maturity.

In May, the government launched a sustainable oil palm production programme, which offers incentives like soft loans, and technical support.

An agro ecological survey identified 31.8 million hectares of abandoned and degraded agricultural areas suitable for oil palm production in the country, nearly equivalent to the size of Germany. But it only authorised plantations on 4.3 million hectares, most of which are in Pará.

The high levels of productivity of oil palm in land near the equator opens up the possibility of diversifying the raw materials used to produce biodiesel in Brazil, where 85 percent of the biofuel is now produced with soy, and of making this country a major exporter of the fuel.

Brazil now imports half of the 450,000 tonnes a year of biodiesel that it consumes.

With a projected annual yield of six tonnes per hectare of oil palm, which has an average productive life span of 25-28 years and is harvested year-round, combined with a growing market for biofuels, the profit margin is ensured, Rosa said. Because of this, investment in biodiesel projects makes sense, even though palm oil fetches higher prices today in the food and chemical industries.

But Agropalma, the only large palm oil producer in Brazil today, “temporarily” stopped producing biodiesel in August, because its prices were not competitive in the public tenders for supply contracts, even though it was making use of the waste products from the oil refining process.

In Colombia, Latin America’s leading producer of biodiesel, it took subsidies to get the industry going. When the government purchases biodiesel, it pays the market price for vegetable oil plus the costs of conversion, explained Jens Mesa, executive president of that country’s National Federation of Oil Palm Growers (Fedepalma).

With its output of 800,000 tonnes a year, Colombia also leads the production of palm oil in Latin America, thanks to the persistence of the private sector, organised in Fedepalma since 1962, Mesa told IPS.

The government’s support was “intermittent” until the adoption of a 2004 law stipulating a minimum blend requirement in diesel fuel of 10 percent biodiesel by 2010, he said.

In Brazil, diesel fuel vehicles will have to run on a five percent biodiesel blend as of January. That target had originally been set for 2013.

Colombia has “three million hectares of land highly suitable for the cultivation” of oil palm, as well as the 365,000 hectares already planted, Mesa said.

Oil palm cultivation is “the only rural activity for which an environmental permit is required” in Colombia, and it benefits 6,000 families of small farmers, he said, refuting criticism by environmentalists.

Central and South America have emerged as a new frontier for African oil palm, in response to growing demand.

But Latin America is seeking to avoid the deforestation and social impacts seen in Indonesia and Malaysia, which together account for 85 percent of global production of palm oil.

The Round Table on Sustainable Palm Oil (RSPO) was formed in 2004 by a diverse group of stakeholders — oil palm producers, palm oil processors or traders, consumer goods manufacturers, retailers, banks and investors, and environmental and social NGOs — to promote sustainable agriculture, address the environmental impact of palm oil and certify products as environmentally and socially sustainable.

To that end, the RSPO has established environmental, social and legal requirements to curb deforestation, allowing expansion of oil palm plantations only on land that has already been degraded.

Petrobras Biocombustível also puts a priority on social inclusion, setting a goal of contracting 2,250 family farmers to produce half of the raw material in one project and 20 percent in its second project, which is focused on export.

Adherence to the laws, reforestation with native fruit trees, education and awareness-raising, and environmental research will form part of the projects, Rosa said.

“Diversity builds,” he said, stressing Petrobras Biocombustível’s commitment to cooperating with small and large farmers and to restoring forests where the land cleared has exceeded the legal limit.

Under Brazilian law, 80 percent of the forest must be preserved on any property in the Amazon.

Despite these safeguards, environmentalists and social activists are critical of the expansion of oil palm plantations.

“We are opposed to any large-scale monoculture, even trees,” in defence of biodiversity and a more balanced climate, said João Pedro Stédile, one of the leaders of the Landless Workers’ Movement (MST) and the Via Campesino international peasant movement.

The native rainforest in Pará is vital to the climate in South America, because of the circulation of humid North Atlantic easterly trade winds in the eastern Amazon, which provide a large part of the rain in the jungle, scientists point out.

In addition, the evaporation from the Amazon jungle, diverted to the south by the Andes mountains, irrigates the most productive agricultural lands in Brazil, Argentina and Paraguay.

Another risk involves plant health. Turning Pará into “a sea of palm trees” will make it very difficult to control pests, warned José Stanley de Oliveira, Agropalma’s phytosanitary manager, who with a team of assistants has so far been able to control the numerous enemies of the oil palm.

There are two especially dangerous pests: the Eupalamides cyparissias borer, which bores into different parts of the tree, and the Rhynchophorus palmarum palm weevil, the main vector of the red ring syndrome in coconut and oil palm, which is “incurable,” Oliveira said.

Biological pest control is the chosen method due to environmental concerns and because “there are only two insecticides” registered for oil palm plantations in Brazil, he added.

Demand for vegetable oils will continue growing faster than the world population and economy, and 13 million additional hectares of oil palm will be needed to meet demand in 2050, according to projections by Conservation International researcher Timothy Killeen. Demand for soy, meanwhile, will require an additional 93 million hectares of the crop.

The high oil yield of oil palm trees and the fact that palm oil does not contain unhealthy trans fats explain the dizzying growth of global palm oil production, which has increased more than nine-fold since 1980.

But it will be hard to come up with a surplus for the production of biodiesel

Singapore To Hold Biofuels Conference In March 2011

Singapore To Hold Biofuels Conference In March

International academia, scientists and experts on biofuels will meet in Singapore in March to identify promising avenues to a viable biofuels future.

The experts will discuss economic and environmental considerations of biofuel technologies and the integration of biofuels into the existing energy infrastructure, while the academia, government and the private sector will discuss and comment on research and policy.

The six-day conference to begin on March 1 is being organised by a United States-based non-profit organisation, Keystone Symposia on Molecular and Cellular Biology, and Singapore’s Agency for Science Technology and Research (A*STAR).

In a statement here Wednesday, A*STAR said the conference titled “Biofuels” will discuss the options of biofuels for an economic and sustainable future, sustainability of cellulosic ethanol (biofuel produced from non-food biomass), algae biofuels (deriving fuel from algae), development of new biomass feedstocks and potential of biomass production in Southeast Asia.

Among the internationally renowned speakers at the conference includes Dr Adam Brown of the International Energy Agency, Professor Timothy Donohue of the University of Wisconsin-Madison/ Great Lakes Bioenergy, Dr Arthur Grossman of Solazyme Inc and Professor Lonnie Ingram of the University of Florida.

One of the conference’s scientific organiser Professor Stephen P. Mayfield of the University of California said one of the greatest challenges that mankind faced today was to develop efficient, sustainable and scalable processes for converting sunlight energy into the food and fuel the world needs.

“No single renewable-energy strategy will be able to provide a total solution but a combination of strategies that can be coordinated and integrated effectively has the potential to significantly decrease our dependence on fossil fuel,” he said.

He added that at this critical time in mapping a new global energy strategy, this symposium would address the potential of cellulosic and algal produced bioenergy as part of a sustainable future for the world.

Keystone Symposia held its first meeting on biofuels last year in US.

Miscanthus discovery could open doors for biofuel industry

Miscanthus x giganteus

Miscanthus discovery could open doors for biofuel industry

In the minds of many, Miscanthus x giganteus is the forerunner in the race of viable feedstock options for lignocellulosic bioenergy production. But researchers believe “putting all their eggs in one basket” could be a big mistake. Scientists at the University of Illinois recently reported the first natural occurrence in several decades of Miscanthus hybrid plants in Japan.

“If M. x giganteus is the only variety available, there are certainly risks involved such as diseases or pests causing widespread establishment problems or yield losses,” said Ryan Stewart, assistant professor of horticulture in the Department of Crop Sciences at the University of Illinois. “We are trying to find Miscanthus hybrids to increase our options. In doing so, it’s a way to hedge our bets.”

M. x giganteusis a sterile triploid (three sets of chromosomes) formed by a natural cross of M. sacchariflorus and M. sinensis. Because it’s sterile, it can only be propagated by vegetative division, which is somewhat more difficult than propagating by seed, Stewart said.

“Because it’s a sterile clone, it’s more or less a dead-end for plant breeders because it can’t be improved through plant breeding,” he said.

Stewart and his team investigated overlapping populations of tetraploid M. sacchariflorus and diploid M. sinensis in Japan in hopes of finding triploid hybrid plants that may be similar in productivity to M. x giganteus. However, finding this occurrence out in the wild is a rare event, he said.

“In Japan, even when two plant species are adjacent to one another, they may have very different flowering times, meaning the likelihood of finding a hybrid is very low,” Stewart added.

But Stewart knew that there were certain areas in Japan where M. sacchariflorus and M. sinensis sat side by side and had overlapping flowering times. So, with the help of his colleagues, Aya Nishiwaki of the University of Miyazaki and Toshihiko Yamada of Hokkaido University, they set out to search for these rare Miscanthus hybrids.

Last year, Nishiwaki was surprised to find a M. sacchariflorus plant, which was adjacent to some M. sinensis plants, with heavy seed set. M. sacchariflorus in Japan normally spreads vegetatively rather than through seed. Nishiwaki collected this seed, grew it out, and then used flow cytometry to determine the genome size of each of plants. Genome size can be used to detect hybridization events. In analyzing several seeds, their research revealed three triploid plants, which, based on some preliminary molecular analysis, were confirmed to be hybrids.

Researchers hope these new triploid plants will express phenotypic traits similar to that of the high-yielding M. x giganteus. But if they don’t, Stewart said they can still serve as sources of genetic variation that might express resistance to recently identified diseases and pests in the M. x giganteus.

M. x giganteus, the first known natural Miscanthus hybrid, was originally found in Japan and then made its way to Europe where it was initially used as an ornamental grass for estates or large gardens, Stewart said. It’s a highly productive grass that’s cold-hardy, notably for plants that use C4 photosynthesis, which are mostly found in the subtropics and tropics.

It is a popular candidate for bioenergy production because it can grow up to 15 feet tall, creating more biomass than other varieties of Miscanthus.

Stewart and his team have received funding to continue searching for hybrids and to build up a diverse collection of plants of several native Miscanthus species throughout Japan. This collection will serve as a resource for the Energy Biosciences Institute located in the Institute for Genomic Biology at the U of I. Future research will also address the phylogenetic relationship of these hybrids with other Miscanthus taxa, and also their agronomic potential relative to the commonly cultivated M. x giganteus.

Stewart’s research was published in the American Journal of Botany. Researchers included Aya Nishiwaki, Shotaro Kuwabara, Hiroya Matuura, Ryo Akashi, Sachi Yamaguchi and Genki Ishigaki of the University of Miyazaki; Aki Mizuguti of the National Institute of Agro-Environmental Sciences; Yo Toma, Tomomi Miyashita and Toshihiko Yamada of Hokkaido University; and Lane Rayburn and Ryan Stewart of the U of I.

Ethiopia gets geared up for biodiesel

Ethiopia gets geared up for biodiesel

Challenged by fluctuating oil prices and stricken with poverty, Ethiopia is searching for a way to boost the nation’s economical situation and perk up the country’s poor living conditions. Some Ethiopian leaders believe that the solution lies in renewable fuels.

Statistics show that Ethiopia spends Birr 10 billion ($800 million U.S. at the current exchange rate) to import petroleum a year. This astounding figure represents nearly 90 percent of the earnings that the country makes each year in foreign trade. By cutting its dependency on foreign oil, Ethiopia could perhaps keep some of the money inside the country and prosper.

In an effort to reduce this crude dependency, the Ethiopian government and its many developmental partners have begun planting crops for use in biodiesel production. Due to Ethiopia’s arid conditions, growers have turned to non-traditional biodiesel plants like castor seeds and jatropha curcas and have found that there are more than 25 million hectares of land in Ethiopia that are suitable for these two types of biodiesel crops. If the land is fully exploited, Ethiopia could become the largest biodiesel producer in the world, cranking out 20 million liters of biofuel per year. That will undoubted bring its own share of problems, but that’s a problem for another time.

Sugar beets could be next big biofuel

sugarbeet

A Fargo-based energy company is moving forward with plans for the nation’s first-ever beet ethanol plant – the first step in an ambitious plan to turn one of the Red River Valley’s top crops into a biofuel mainstay.

A Fargo-based energy company is moving forward with plans for the nation’s first-ever beet ethanol plant – the first step in an ambitious plan to turn one of the Red River Valley’s top crops into a biofuel mainstay.

The proposed plant was announced Monday by Green Vision Group, which touts beets as a cleaner, more efficient alternative to corn, which dominates current ethanol production. Lloyd Anderson, one of the Green Vision partners, said the company hopes to have a pilot beet ethanol plant up and running by 2012.

That plant would be a small-scale operation meant to demonstrate the viability of the ethanol beet technology and business model. It’s being developed in conjunction with an ethanol producer. Anderson did not identify the partner company or the planned site.

The test plant is expected to cost about $5 million. Green Vision Group is seeking money from the North Dakota Legislature. Eventually, the company plans to build a dozen larger production plants, with each expected to cost about $43 million. Commercial production of ethanol beets could start by late 2013 or early 2014.

The company hopes to produce 240 million gallons of ethanol per year. The state now has the capacity to produce about 350 million gallons of corn ethanol a year – about 2.5 percent of the nation’s ethanol production.

To reach those production levels, Green Vision’s plan calls for about 360,000 acres of energy beets, which are modified sugar beets grown specifically for fuel production rather than sugar. Green Vision Group president Maynard Helgaas said those acres might come from a combination of underdeveloped land and land that’s now being used by corn or other crops. Sugar beets accounted for about 220,000 acres in the state this year, while corn accounted for about 2 million acres.

Helgaas said focusing on beet ethanol makes sense for a number of reasons. Green Vision’s figures show that beets produce twice as much ethanol per acre as corn and require about 40 percent less water per gallon of ethanol produced. Using beets instead of corn also sidesteps the controversy associated with using a food product for fuel.

“This is probably the most efficient use for an acre of land for biofuel as there is,” Helgaas said.

Ultimately, the company hopes beet ethanol will qualify as an advanced biofuel – a fuel that cuts baseline carbon emissions by at least 50 percent. That would position the industry to capitalize on escalating Environmental Protection Agency standards that call for producing tens of billions of gallons of advanced biofuel a year by 2022.

The four partners in Green Vision Group – Anderson, Helgaas, Rudy Radke and Rod Holth – all have backgrounds in North Dakota agribusiness. The company is working with Heartland Renewable Energy, an Iowa company that developed much of the technology for the beet test plant. That includes a waste recycling system expected to provide about 70 percent of the plant’s power by burning beet waste. The ash can also be used as beet fertilizer.

Heartland president Rick Whittaker said he realized some time ago that corn wasn’t the most efficient candidate for ethanol. As he explored alternatives, he said, “It was clear to us the best bang for your buck was with beets.”

Whittaker said he wound up working with a North Dakota company because Iowa’s corn-growing establishment wasn’t receptive to his pro-beet mantra.

A similar conflict here doesn’t appear to be in the offing. Tom Lilja, executive director of the North Dakota Corn Grower’s Association, said the state’s corn growers hope “anybody that can make a profit in agriculture” finds a way to do so.

“We certainly hope they can make it work,” he said.

Biofuels Get Test at Danish Pumps

Biofuel fuel pump

Danish companies see a big business potential in helping to curb the world's reliance on petrochemicals.

Danish companies see a big business potential in helping to curb the world’s reliance on petrochemicals.

Danisco AS and Novozymes AS, which together cover 70% of the world market for enzymes that go into making second-generation ethanol, are collaborating with ethanol producer Inbicon AS in manufacturing a biofuel that is being sold across Denmark.

The new fuel blend, which costs about ten U.S. cents more a gallon than regular gas, has been sold since late October by about 100 Statoil gas stations. “The extra cost is a bit more than normal, but not much. “It’s about the price of one Coke for a full tank,” says Danish motorist Carl, 44, who declined to give his full name.

The new fuel is a blend of gasoline and second-generation ethanol. If the experiment succeeds, it could become part of a business worth billions of dollars, say energy analysts.

The two companies supply enzymes to Inbicon, which produces the ethanol at a plant in western Zealand, Denmark. Whereas first-generation ethanol is made from plant products, such as corn, wheat and sugar beets, that could otherwise be used for food or feed, second-generation ethanol is made from agricultural waste materials—straw husks and leaves—and therefore avoids being embroiled in any fuel-versus-food controversy.

“We need to find ways to change the chemicals that go into the machines we use, in a way where we’re not dependent on oil,” says Tom Knutzen, Danisco’s chief executive, who believes developing second-generation ethanol will pay huge business dividends. “It’s humongous,” he says.

The two most common forms of biofuels are biodiesel and ethanol. Biodiesel, made by combining alcohol with vegetable oils or animal fats and recycled cooking grease, remains the biofuel of choice in Europe, while Ethanol is widely used in the U.S. As a result, Danisco wants to establish a significant presence in the U.S. market.

According to the Renewable Fuel Standard program implemented in 2005 and reconfirmed by President Barack Obama’s administration, 36 billion gallons of renewable fuels for use in the U.S. will be produced yearly by 2022, and Denmark wants a share. Currently, U.S. production of first-generation ethanol is about 12 billion gallons a year. But much of the gap is expected to be filled by second-generation ethanol—a business that management consultant McKinsey & Co. forecasts will be worth from $75 billion to $140 billion world-wide by 2020.

Aside from being Inbicon’s supplier, Danisco has a joint venture with DuPont Co. to develop second-generation ethanol. Mr. Knutzen says results from the trials of this project will be presented next year and he expects a commercial plant to be up and running in the U.S. by 2013. So far, Danisco and DuPont have invested $140 million since the joint venture was founded in 2008, he says.

Statoil’s second-generation ethanol project isn’t the only one of its kind. BP PLC, and Royal Dutch Shell are among other companies investing into advanced biofuels. BP bought a stake in Brazil’s Tropical BioEnergia SA and has said that it plans to transfer technology for second-generation ethanol to its mills in Brazil for the 2013-14 crop season. Shell has a joint venture with Brazil’s Cosan SA Industria e Comercio to accelerate the development of second-generation ethanol from cellulosic agricultural waste, although Shell says the project remains at an early stage.

In the Danish experiment to see if second-generation ethanol can replace traditional fuels at the pump, motorists using the Statoil stations now have the choice of Bio95 2G as well as regular gas and diesel that are sold alongside. Statoil says the experiment is already considered a success—on the grounds that the biofuel is now available and that despite the higher price consumers are buying it. The next step is to have more plants producing second-generation ethanol, Statoil says.

Involvement with a new biofuel is all quite a change for Danisco, which was founded in 1989 after the merger of several Danish companies with roots stretching back to 19th century sugars and distillery firms.

The 48-year old Mr. Knutzen runs Danisco out of an old sugar warehouse, now refurbished into the company’s headquarters, in Copenhagen.

Danisco sold the last vestiges of its sugar business last year and today makes its money by supplying enzymes, dairy cultures and enablers—emulsifiers that bind together vegetable oil and water—to the global food industries. Today, Danisco food ingredients or enzymes are included in ice cream and yoghurt, as well as laundry detergent and other products.

Now the company wants to put its knowledge of enzymes into getting the planet “off the oil,” Mr. Knutzen says.

It’s no easy task. To extract ethanol from plant waste is a tricky process. The enzymes, proteins that speed up the chemical process, are used to transform the plant waste into fermentable sugar and then into sustainable fuel. But with regard to second-generation ethanol, the big challenge is no longer the technology but developing a raw material supply chain, Mr. Knutzen says. Commercial plants will require large amounts of biomass that need to be harvested, transported and stored, he adds.

Mr. Knutzen says Danisco has an important role to play in reducing the world’s dependency on petrochemicals. “Of course, it not a question of one technology solving everything. You need all kinds of technologies, wind power, solar power, etc. But second-generation ethanol, for example, definitely takes care of the transportation sector. And that is a big part of the world’s sustainable future.”

Report Examines Corn, Soybean Use for Biofuels

Report Examines Corn, Soybean Use for Biofuels

With world demand for corn and soybeans on the rise, supply of the nation’s two major crops must be watched closely by pork producers. Add the increasing demand of the biofuel and ethanol industries, challenging weather conditions and dwindling reserves, and you have the makings for tight supplies for both commodities.

In a report titled Corn and Soybean Availability for Biofuels in 2010-2011, Robert Wisner, professor emeritus, Iowa State University, examines the potential adequacy of supplies of the two crops for the upcoming year.

“Corn supplies will be tight and some rationing of demand likely will be needed in the year ahead,” according to Wisner. In addition, he believes more corn acres will be needed next year to meet continuing demand growth.

For the coming year, Wisner expects a further expansion of corn use for ethanol, but at a much slower pace than in recent years as the industry approaches a “blend wall”. Increased demand from the recent partial approval of E-15 is likely to occur gradually rather than in an immediate demand surge, according to Wisner.

As for soybeans, projections show adequate soybean supplies for the year ahead unless final U.S. soybean yields are modestly lower than currently indicated. Wisner expects domestic soybean crushings to decline moderately from last year. Soybean supplies for 2010-2011 look slightly more adequate than those for corn, but with similar variables determining the degree of tightness.

Biofuel production begins to have impact on Angolan econom

Biofuel production begins to have impact on Angolan econom

Biofuel production begins to have impact on Angolan econom

Biofuel production is beginning to have an impact on Angola’s economic growth, and is one of the factors behind current growth levels, together with a rise in oil production and more public investment, according to the Economist Intelligence Unit.

In its most recent report on Angola, the EIU for this year forecasts economic growth of 5.9 percent, a which is a string recovery in relation to the contraction of 0.9 percent estimated for last year.

“We expect a string upturn in 2010, supported by a rise in production and oil prices, robust public investment and the start of production of the first biofuel projects,” the EIU said.

Next year’s economic growth is expected to accelerate in line with a rise in oil production.

The Liquid Natural gas (LNG) project, expected to cost US$8 billion, is expected to contribute to a new surge in economic growth in 2012, to 9.4 percent.

In that year Angolan exports are expected to total US$60.7 billion, a third more than those for 2009.

“The forecast is that they will remain generally stable from then on, thanks to slowing in the rise of (oil) production and price moderation,” the Economist said.

The EIU also gave average growth projections for 2013 and 2014, which it estimated at 7.7 percent, and noted that economic expansion would continue to require intensive capital and be dependent on imports as well as being focused on activities such as construction and the financial sector.

Foreign investment is expected to continue to be dominated by Portuguese, Brazilian and Chinese capital, the EIU said.

According to the National Agency for Private Investment (ANIP), in the first six months of the year proposals for investment in the non-oil sector exceeded US$1.25 billion, which was more than three-fold the proposals received in the same period of last year.

Portuguese bank BPI also recently published its projections for Angolan economic growth, which are more conservative than those of the Economist.

For this year, BPI pointed to a rise in GDP of 5.0 percent, accelerating to 6.1 percent and then remaining at around 5.1 percent in the two following years.

These projections are below figures from the revised State Budget, which points to growth of 6.7 percent in 2010, which is below the previous 9.7 percent.

The “positive performance” of the Angolan economy in the first half of the year, BPI said, was due to “recovery of the export sector, due to a rise in world demand and oil price rises on the international market,” as well as improved conditions in the diamond market, which is the second-largest export product.

“The signs from the non-oil sector point to a positive contribution to this year’s GDP. Despite a more restrictive tax policy, under the terms of the agreement with the IMF, public investment took place at a higher rate in the first few months of the year,” it said.

Investment could even be at a higher level, if there had not been an accumulation of delayed payments by the State.

In a report published last week, the IMF also projected growth for the Angolan economy, following a downturn last year.

“The Angolan economy is gradually recovering: (…) foreign currency reserves are being replaced, the budget is in a surplus situation and the level of delayed payments has been reduced since the middle of the year,” said the report on the latest IMF mission to Luanda.

The rise in oil prices and greater containment of expenditure are behind the improvement in public accounts, it said.

For 2011, the IMF continues to project a, “solid rate of growth,” as temporary factors such as problems with oil production are eliminated.

New plant cultivar could yield biofuel oils

A new partnership between crop and oil producers may yield biofuel from jatropha, a non-edible plant capable of growing in marginal soil unsuitable for food crops.

SG Biofuels, a bioenergy crop company, is developing and producing elite jatropha seeds. It has established a strategic partnership with oilseed processor Bunge and a team of partners, including refining and petrochemical company Flint Hills Resources, to research and develop a model to process jatropha seeds into biofuel feedstock.

Jatropha is a non-edible shrub native to Central America. Its seeds have high oil content and can be processed to produce a high-quality energy feedstock. SG Biofuels has introduced JMax 100, an elite jatropha cultivar optimized for growing conditions in Guatemala, with projected yields 100 per cent greater than existing commercial varieties.

Common roadside plant could become new source of biofuel

Common roadside plant could become new source of biofuel

U.S. Department of Agriculture (USDA) studies have revealed that a common roadside plant could have the right stuff to become a new source of biofuel.

Scientists with the Agricultural Research Service (ARS), USDA’s principal intramural scientific research agency, have found that field pennycress yields impressive quantities of seeds whose oil could be used in biodiesel production.

Field pennycress belongs to the Brassicaceae family, along with canola, camelina and mustard-other prolific producers of oil-rich seeds. The ARS studies help support USDA’s efforts to develop new sources of bioenergy.

At the ARS National Center for Agricultural Utilization Research in Peoria, Ill., chemists Bryan Moser, Gerhard Knothe and Terry Isbell and plant physiologist Steven Vaughn formed a team to study field pennycress’ potential.

The scientists obtained oil from wild field pennycress, pretreated it with acid, and used a type of alcohol called methanol to react with the field pennycress oil to produce both biodiesel and glycerol. After some additional refining, the finished biodiesel was tested to see if it met the biodiesel fuel standard established by the American Society for Testing and Materials. The results suggested that, with some work, the previously problematic pennycress could become a commercial commodity.

All diesel-based oils start to gel when it’s cold enough. So the cloud point, which is the temperature at which crystals become visible in the fuel, is a crucial factor in both biodiesel and petrodiesel production. Another important property is the pour point, the temperature at which the fuel fails to pour as a result of excessive solidification.

The average cloud and pour points for field pennycress biodiesel were 14 degrees Fahrenheit (minus 10 degrees Celsius) and minus 0.4 degrees Fahrenheit (minus 18 degrees Celsius), respectively. These temperatures were well below the cloud and pour points of soybean oil-based biodiesel. This result suggests that field pennycress biodiesel is better suited for use in cold climates than many other biodiesel fuels, such as soybean oil-based biodiesel.

Pennycress can be grown during the winter and harvested in late spring, so farmers who cultivate pennycress can also maintain their usual summer soybean production without reducing crop yields.

Results from this work have been published in Energy and Fuels. (ANI)
