This Brazilian’s Obsession: Get the World to Use His Biojet Fuel

Biokerosene creator, Expedito ParenteAt age 66, Doutor Expedito has never been so requested. His biokerosene should pave the way for reducing carbon dioxide emissions in aviation and for a gradual substitution of ordinary jet fuel. Tests have been performed since mid-2006 and are believed to soon enter a decisive stage at Boeing, the aircraft manufacturer based in Seattle (WA), with NASA, the space agency, also collaborating actively.

Contrary to bioethanol and biodiesel already established in road transportation worldwide, biojet fuel is a vegetable product which has still not been in commercial use.

For a long time, Expedito Parente was a professor at Ceará Federal University in Fortaleza, a large city in Brazil’s Nordeste region. When he retired, this hyperactive academic needed something essential to do. In 2001, he thus founded Tecbio, a small engineering firm conceiving biodiesel refineries.

It was nicely timed. Tecbio has now a staff of 80 and is growing exponentially. But Dr. Parente nourishes a double obsession really: to be the first to make airlines adopt biojet fuel, an important technological step ahead of ordinary biodiesel, and to have this biofuel produced in a socially correct way.

In 2005, professor Parente won the Blue Sky Award for his aircraft fuel project, “a kind of Nobel prize given by the UN for innovations in the field of renewable energies”, he comments.

Interest for the invention was confirmed in the beginning of this year at a Washington D.C. seminar organized by the Transportation Research Board, a government agency. In the very long run, algae and cell fuels are thought to stand for permanent solutions. But participants were confronted with an apparently absurd question: “May babassu already be a renewable source to serve as substitute for jet fuel?”

This totally unknown palm tree (outside Brazil) grows in the wild on forty-five million acres. Such huge area corresponds to six Marylands. It was Expedito Parente who discovered that the nuts of the babassu – or more precisely the kernels within – possess energetic proprieties which are ideal for conceiving biojet fuel.

There are certainly social and ecological arguments in favor of the babassu: its use does not contribute to food shortages, nor does it imply deforestation.

Spectacular Comeback

In reality the discovery is not recent. To some extent Professor Parente is performing a spectacular comeback. In the 80s he was the first in the world to patent biodiesel as an industrial process. He was acclaimed as the “Father of Biodiesel”.

This brilliant academic was then asked to find a vegetable substitute for aircraft fuel. The product resulting from this research made a turboprop transportation airplane fly a distance of some 600 miles in 1984. So why did not aviation worldwide adopt his biokerosene?

– At the time, petroleum prices went down dramatically. And we must understand that a fuel to be acceptable for modern jetliners has to be extremely reliable and resistant at very low temperatures, it is a complex product, he explains.

There is a new dimension to what is at stake. To fly from London to Rio, and back, provokes individually as much CO² emissions as those generated during fifteen months of sedentary life in a European capital, heating and local transportation included, if we are to believe comparative studies of environmental impacts. Already, air transportation operators supply travelers with different service contributions to buy, in compensation for greenhouse effect emissions.

Globally, airlines gulp down 26 billion gallons of fuel per year, and this figure may double in twenty years. 20% of their operational costs correspond to fuel. For the first time in 2006, the fuel bill exceeded costs for staff in the sector. Sir Richard Branson, British business mogul, scorching supporter of many environmental causes, but mainly founder and president of the Virgin group which counts several air transportation carriers, said in a recent interview that “immediate solutions” should be found.

Could the babassu make the difference ? A Brazilian law grants the local population the right to collect babassu nuts freely, independently of who owns the land. A situation of ecological balance totally opposed to the one to be observed in Malaysia or Indonesia, known to shelter the largest palm tree plantations in the world, but also to encourage deforestation and boost the greenhouse effect indirectly, as the original jungle is frequently left to be burnt down.

Today, biojet fuel does not seem to be entirely competitive though, as jet fuel derived from petroleum is sold free from taxes at 1.5 USD per gallon, which is still very cheap.

“Soon there will be eco-taxes on aviation fuel. And I am pretty sure that authorities will make it mandatory to blend conventional fuel with biojet when available. Costs will also shrink significantly when industrial production is started,” underlines Dr. Parente.

But would not land areas needed be gigantic? Doutor Expedito has a ready answer:

“If 20% of aviation fuel were to be produced in form of green fuel for blending, such volumes would correspond to some 30 million acres land. It’s a huge territory, I agree, but it is less than the existing babassu forests.

Tecbio and its involuntarily hype boss have furthermore a very clear social vision. This is important to emphasize, as bioethanol mills using sugar cane as raw material has not reduced poverty in the Brazilian countryside. Seasonal plantation workers called bóias frias (“cold billies”) have a hard time. Because of piece-work, a Brazilian cane cutter will only ‘last’ 12 years, less than a slave in ancient times, according to a recent study.

Professor Parente gets upset:

“Such conditions are intolerable. We have our own model which pretends to reconcile social development and industrial dynamics. At present date, Tecbio is leading two pilot projects in collaboration with federal authorities. The idea is to create cooperative units, in association with the local population, for a socially correct production of biodiesel derived from babassu kernel oil. Respecting the environment, this model should be replicated in other regions, for examples in deforested areas of the Amazon and in Africa.”

But it is not utopian wanting to assemble two operational methods which are normally dissociated: the small-scale traditional way with output through high-tech plants? Expedito Parente holds out his arms. He makes one think of a talented film maker who, after years of prospecting, has just received unlimited funds to shoot an ambitious picture based on an art script:

“One has to be pragmatic. We work with feasibility from an economic point of view. Running a cooperative does not mean that it should not be profitable. In a basic scheme, each cooperative shall produce three million liters (800,000 gallons) of biodiesel/biojet fuel per year, together with several other products originated from the nuts.

There will be some agriculture. All the electricity consumed in the cooperative shall be generated organically on the spot. Each cooperative is giving part-time jobs to 3,000 peasants. On the other hand we study also ecologically run babassu plantations.”

To produce one billion liters of biojet fuel, (270 million gallons) at least 300 such cooperatives are needed. This is certainly a time-consuming project. Plans are allowed to be extensive though, changeover seems to be secured. Of four children, Doutor Expedito has one son working at Tecbio. At age 26 and a chemical engineer as his father, he already takes part in management. His name is premonitory: Expedito Parente Junior…
