The world is coming increasingly to the last frontier of fossil fuels. There wont be oil forever. Is it time to accelerate the pace in the production of bioenergy, biogas and biofuels as an alternative? Some countries are already doing it, and Argentina should not miss the train. Germany is a leader in developing technologies for renewable energy, both substitution of fossil fuel from petroleum and in reducing the emission of greenhouse gases. In the United States, Barack Obama carries out his “green agenda”, which in full presidential campaign announced the creation of three million jobs and boosting energy agriculture. “These days the U.S. government has increased the levels of investment in laboratories and research to 15.000 dollars. This career resembles that of the sixties, which was to lead man to the moon,” said Engineer Jorge Hilbert, of the Institute for Rural Engineering, from the National Institute of Agricultural Technology (INTA). In South America, countries like Peru, Chile and Brazil are developing these technologies. Last week in San Pablo, took place the second summit of Ethanol to discuss the future of this biofuel. At the end of this month, China will held in Beijing a symposium on biofuels and ethanol. “Both China and India understand very well that they should open their borders to the entry of green technologies. They learned and implemented by themselves, “said to La Nacion TobÃas Winter, supervisor of the Environment and Renewable Energy of the German-Argentine Chamber of Industry and Trade in Buenos Aires. Both Hilbert and Winter participated in the Argentine-German Technology Forum of Bioenergy, held last wednesday in Buenos Aires and where other specialists spoke. In the country Since last year in Argentina, INTA conducts the National Bioenergy Program. “The projects are aimed to different sources of biomass (plants, agricultural and agro-industrial waste, etc.) The use of this biomass ends in bioenergy,” defined Hilbert. And what is meant by bioenergy? “It is any component of biological origin that can be converted into what we call an energy vector that can be gaseous, liquid or solid, and this definition exclude oil, gas and coal, which has the same origin but spent millions of years for that to be stored in the depth of the diferent layers of soil. ” One project works on waste and crops with energy purposes. Another is aimed at developing of strategic crops such as jatropha (a plant family of the risin, is an evergreen shrub from tropical and subtropical areas) and a third deals with what are biofuels of second and third generations, who are related to the use of cellulose. Why it’s worth thinking about bioenergy?, “Because it’s one of the energetic alternative in which are included solar and wind energies,” Hilbert said, but cautioned that it is not the solution for the replacement of oil. In the case of biodiesel, Hilbert said that the installed capacity in Argentina is about one and a half a million tonnes of production in facilities located near the port of Rosario, where also are oil.companies lifted. But he added that the biodiesel industry has strong swings in the market so is not surprising that at certain periods the plants are not operational when it is more profitable to export the oil directly. As mentioned, this activity in the country is emerging. And some cases serve as an example. This applies to the company Bio Metanos del Sur SA. Juan Pablo GarcÃa Delfino, of the Commercial Department, explained how they work. “Five years ago we began to seek a environmental solution to odors which came from the breeding place with a staff of 10,000 animals, located about four kilometers from the center of Marcos Paz, located 50 kilometers from Capital Federal,” said the businessman. “Because here in Argentina we do not find solutions, the manager of the company, Hugo Garcia, traveled to Brazil, where he contacted a Japanese company that was installing its first biodigestor in the country,” said Delfino Garcia. He explained that with an investment of $ 150,000 they brought in new equipment for the breeding place. The biodigestor is like a big tight PVC bag in which are deposited by a pipe (also fusing PVC) manure, animal urine and water for cleaning barns. “In 30 days, by a fermentation process biogas emerges, it accumulates at the top of the structure while via communicating vessels fluid drains into a containment pond and then are used as fertilizer,” he added. The biogas is used to heat the soybeans (it turns off the protein that animal can not digest) for own use in feeding their herds and third, which represents the savings of buying gas (18,000 pesos per month ) and extra revenue for the service to other hatcheries. Another example One of the speakers of the forum, Karl Reinhard Kolmsee, from the company Smart Utilities Solutions GmbH of Germany, showed a case of a client they have in Peru. It is a poultry farm, which he did not know what to do with the accumulation of guano, which is very aggressive to be used directly as fertilizer. ” Then, according Kolmsee, the company decided to incorporate biodigestors with which, after the fermentation process, gets the gas for the heaters in the barns of the farm, and to fuel electricity generators, while the liquids are used as fertilizers.
