Its supporters say the industry helps the environment, creates jobs, and boosts economic growth. But biodiesel fuel remains a polemic issue, especially in South America, where its use has grown considerably in recent years.
In Argentina, the industry has grown by 2250% since 2006 and has become the world’s fourth largest biodiesel producer, according to the Argentine Chamber of Renewable Energy. Growth is expected to be propelled further by a law approved last year stating that all petroleum derived fuel in Argentina should include 7% of biodiesel. Investors, drawn to Argentina’s large agricultural sector, relatively cheap land and inexpensive labour, are ploughing millions into biodiesel production.
According to Roberto Urquía, the former senator and owner of the Aceitera General Deheza (AGD), one of the biggest producers of biodiesel in the country, by 2015 biodiesel production in Argentina will reach 7million tons, almost triple the current output.
Carlos St James, CEO of Rubenius Argentina SA and president of the Argentine Renewable Energies Chamber, believes the government is starting to pay more attention to cleaner forms of energy with the development of wind and solar panels and of course, the biodiesel industry.
St James believes Argentina has an extremely efficient production of biodiesel and right now figures show the country can produce 2.5 million tons by the end of this year, which will bring US$3bn to the economy. “It is good for the environment and will also create many jobs,” he says.
Food vs Fuel
Despite the supposed economic and environmental benefits of increased biodiesel production, the industry has its critics, largely due to its potential impact on food supply.
99% of the biodiesel produced in Argentina is the first generation type, which means it is made out of food-producing plants like soybeans, canola and palm trees. The national production focuses mainly on the oil derived from soybeans.
The use of first generation biodiesel divides opinion since the biodiesel and food industries will be competing with each other to get the material for their final products. If more crops are processed as biodiesel, fewer are harvested for food, causing prices of basic foods to rise.

“In a world with hunger it is unjust to use food to produce fuel”, states St James. On the other hand, he says that “the food vs. fuel debate doesn’t apply to the soybean biofuel,” which is the one mainly produced in Argentina. The reason is that the sectors require different parts of the soybean plant: 85% is protein and used to produce food, whereas soy oil is used for the production of biodiesel is the rest. “Argentina is producing more and more soy, which complements food production. This means the more soy you have, more food you get.”
However, even if most of the soybean biodiesel crops will also supply the food industry, it does not mean that there will be no shortage of agricultural production in the long run.
There are two potential soy crops per year and the ideal to have a healthy soil is to alternate crops, since the soybean plantation takes a lot of nutrients out of the soil. The farmers in Argentina are planting soybean crops over and over again, which might lead to infertile lands and scarcity of agricultural products for both food and biodiesel in the future.
Furthermore, Argentina only consumes a small fraction of its national soy crop (most is exported to China), so increased soy production at the expense of other crops such as wheat and corn can affect national food supply.
Efforts are being made to lessen the food vs fuel debate. A second generation of biodiesel is made out of non-food products such as leaves, husk and stems as well as other non-food crops, such as grass, though this accounts for just 1% of biodiesel production in Argentina at the moment.
Meanwhile, so called “advanced biofuels” are being developed, promising to provide more effective and renewable energy without diminishing food crops. For example, the Gliocladium roseum, a fungus found in a Patagonian forest in 2008, has in its composition several different molecules of hydrogen and carbon, which are also found in diesel. According to professor Gary Strobel from the Montana State University, “this is the only organism that has ever been shown to produce such an important combination of fuel substances.”
This means Argentina might have a great economic advantage in the next few years with the development of clean energies. “This fungus can even make these diesel compounds from cellulose, which would make it a better source of biofuel than anything we use at the moment,” adds the scholar.
Prioritising the Domestic Market
With these new forms of biodiesel still undeveloped, first generation biodiesel production is set to continue growing in Argentina. Indeed, despite concerns about use of food crops for fuel, for now, biodiesel producers in Argentina are more worried about overcoming barriers to trade.

Santiago Sanchez, one of the researchers at AGD, says that the company exports more than 80% of their output to over 80 countries, especially the EU. According to Sanchez “the constant changes to the commercialising laws of agricultural products is the main concern of the company when it comes to the internal market.”
In addition, some European countries such as Spain are trying to defend their domestic market by adopting protectionist measures against Argentine soy and biodiesel.
With this in mind, the government is trying to prioritise the internal market. According to Javier de Urquiza, coordinator of the National Bio-fuel Programme. “The message now is ‘less exports and more domestic market’. This is the big challenge for the sector,” stated Urquiza. Minister of federal planning, Julio De Vido, also declared last month that “the profits generated by the bio-fuels should stay [in the country] to sustain growth.”
One idea to stimulate local demand is to again increase the minimum amount of biodiesel in petroleum-derived fuels to 10%, something currently under consideration in government. However, St James says if there is more than 7% of biofuel some vehicles might suffer from engine problems. “The automotive industry is not ready for that” as the engines are not prepared to receive over a certain amount of biodiesel. “That is their dirty little secret.”
