ABSTRACT

ABSTRACT In Brazil, there are several crops producing oil for biofuel production, such as canola, sunflower, peanut, cotton, castor bean, soybean, among others. There are parameters that indicate the energetic and economic viability for the production of biofuels, and that can be applied, for example, in transgenic soybeans. The present study aimed to evaluate the energetic viability of Intacta RR2 PROTM soybean for biofuel production.Experiments were conducted in the municipalities of Palotina and Marechal Cândido Rondon, both in the State of Paraná. Energy balance calculations were carried out from the production system, estimating energy expenditure, including the agricultural and industrial stages. The inputs used were considered as input of energy, while grain production, as output of energy. The energy balance of soybean biofuel showed positive values in the treatments with lower doses up to the recommended doses, highlighting the treatment glyphosate at 720 g.e.a. per hectare, which reached a positive energy balance (1: 1.11) for both municipalities. However, the Intacta RR2 PRO TM soybean was sensitive to treatments with high doses of glyphosate, which impaired productivity and consequently generated low economic returns.

ABSTRACT

En Colombia durante las últimas décadas se ha implementado la producción de biocombustibles como una alternativa a la utilización de combustibles fósiles, se busca que nuestro país se convierta en uno de los primeros productores, razón por la cual el gobierno ha trabajado lo necesario para lograrlo. Uno de los principales promotores del desarrollo de los biocombustibles en Colombia ha sido el expresidente Álvaro Uribe Vélez, es por ello que en este trabajo se hace un análisis desde la perspectiva de la bioética de Van Rensselaer Potter a discursos pronunciados por el expresidente durante su mandato, con el fin de elucidar si se encuentran posturas bioéticas. Para el desarrollo de la investigación se utilizó la metodología del análisis del discurso, encontrándose que en los planteamientos de Uribe Vélez sí se encuentran posturas bioéticas, aunque también se perciben contradicciones frente al manejo que da al concepto de naturaleza.


In Colombia in recent decades has been implemented biofuel production as an alternative to fossil fuel use, it is intended that our country become one of the leading producers and for this the government has worked to the extent necessary to achieve it. One of the major promoters of the development of biofuels in Colombia has been the president Alvaro Uribe is why in this paper is an analysis from the perspective of bioethics Van Rensselaer Potter to expresident speeches, in order to elucidate if they are bioethical positions. For the development of the research methodology was used discourse analysis, finding once applied this, that speeches by Uribe Velez are bioethical positions, but also perceived contradictions about the management which gives the concept of nature.


Na Colômbia, durante as últimas décadas tem sido implementada a produção de biocombustíveis como alternativa ao uso de combustíveis fósseis. Procura que o nosso país se torna um dos primeiros produtores, para que o governo tem trabalhado. Um dos principais promotores do desenvolvimento dos biocombustíveis na Colômbia foi o antigo presidente Álvaro Uribe Vélez; portanto, este trabalho faz uma análise na perspectiva da bioética de Van Rensselaer Potter para discursos entregues pelo antigo presidente durante seu mandato, a fim de elucidar se são posições bioéticos. O desenvolvimento da pesquisa foi a metodologia de análise do discurso, encontrado nas abordagens de Uribe Vélez são posições bioéticas, mas encontrando também percebida contradições diante de gestão que dá ao conceito de natureza.

ABSTRACT

Plantea sobre la problemática de los combustibles, su agotamiento y alto costo que incentiva a indagar la obtención de energías alternativas como el biogas, biodiesel y bioetanol, a partir de la hidrolisis de residuos agroindustriales, contribuyendo de esta manera a la biorremediación.
