“…The effect of the FU can be explained by the fact that the soybean has an oil content lower than rapeseed, meaning that large areas of land are required to obtain the same amount of biodiesel, and that more environmental impacts are generated. Therefore, several authors have questioned whether soybean is actually a suitable raw material for biodiesel (Asal et Lamers et al, 2008;Tomei & Upham, 2009;Milazzo et al, 2013b). It is also necessary to take into account the risk of displacement of other crops, which is higher for soybean compared to rapeseed, which could pose a threat to biodiversity, climate change and food security.…”

Rapeseed oil is expected to be increasingly used in Spain as raw material to produce biodiesel to the detriment of extra-EU imports of biodiesel mainly based on soybean oil from Argentina. Therefore, the environmental impacts produced throughout the life cycle of energy crops used to produce biodiesel which is consumed in Spain could be radically affected. In this context, the environmental impacts of rapeseed cultivation in Spain and soybean cultivation in Argentina, were compared under certain growing conditions using Life Cycle Assessment (LCA). Two methods of calculation for Life Cycle Impact Assessment (LCIA) and two functional units (FUs) were used to test potential biases. The results showed that the cultivation of soybean in Argentina had, in general, fewer environmental impacts than rapeseed cultivation in Spain when the FU was the area of cultivation, but these findings are inverted when the analysis is conducted according to the energy content of the biodiesel obtained from these crops. Soybean in fact has very low oil content, meaning that larger areas of land are required to obtain the same amount of biodiesel and that consequently it has a higher environmental impact by energy content. Fertilization was, in general, the process that generated the greatest environmental burdens, and is an area in which improvement is necessary in order to increase sustainability, particularly with regard to Spanish rapeseed.Additional key words: LCA; biodiesel; impacts; CML-IA.Correspondence should be addressed to Francisca Fernández-Tirado: fernandez@uma.esAbbreviations used: ASNPB100kmFF (the amount of seed (kg) needed to produce the biodiesel that would be required to drive 100 km in a diesel Ford Focus 1.8 TDdi 89HP); EU (European Union); FU (functional unit), GHG (greenhouse gas); LCA (life cycle assessment); LCI (life cycle inventory); LCIA (life cycle impact assessment), NT (no till); REOS (respiratory effects of organic substances).

“…In accordance with Berrios and Skelton (2008) and Lamers (2010), a water/biodiesel ratio of 0.5/1 was used in our calculations, employing multiple successive washing steps. Most of the new biodiesel industries have a wastewater treatment plant and most of the industrial process water which is not evaporated is reused.…”

“…O grande consumo de produtos derivados do petróleo, como a gasolina e o diesel, e o crescente esforço em reduzir o aquecimento global causado pelas emissões dos gases poluidores, aumentam a busca por combustíveis alternativos que sejam renováveis e resultem em menor impacto ambiental (LAMERS; McCOR-MICK;HILBERT, 2008). A energia proveniente da biomassa é apontada como uma grande opção na procura por novas fontes de energia, e o biodiesel aparece como uma alternativa promissora nesse quesito (DEMIRBAS, 2008).…”

 RESUMOTrabalhou-se com o tema biodiesel na forma de projeto de intervenção, na disciplina de química no terceiro ano do ensino médio de uma escola pública de Rorainópolis -RR em 2015. A proposta permitiu a contextualização da temática com o ensino de química, a sensibilização ambiental em relação ao resíduo de óleo de fritura, interação entre os estudantes, além de incentivar a busca de conhecimento e de tornar as aulas mais interessantes. Fez-se um levantamento sobre o conhecimento prévio dos estudantes sobre a temática vinculando alguns conceitos de química orgânica. Após o diagnóstico, desenvolveu-se uma sequencia de açõespara a aplicação do projeto. Na parte prática, os estudantes ajudaram a montar a miniusina e a maquete, e perceberam o significado de se pesquisar, projetar e também de preservar o meio ambiente. Ao final realizou-se a avaliação da metodologia na aprendizagem. Os resultados foram muito satisfatórios e percebeu-se que os estudantes se identificam melhor com aulas diferenciadas e projetos que envolvam experimentação relacionada ao conteúdo trabalhado em sala de aula do que com as aulas tradicionais. Sendo assim, o professor deve se esforçar para melhorar sua prática pedagógica a fim de melhor ensinar. Palavras-Chave: Tema Transversal. Ensino de Química. Resíduo de óleo. PIBID. ABSTRACTWe worked with the biodiesel theme in an intervention project related to a discipline of Chemistry, in the third year of high school, of a public school in Rorainópolis -RR in 2015. The proposal allowed the contextualization of the theme in the teaching of chemistry, the environmental awareness regarding to frying oil residue, interaction among students, and encouraging the search for knowledge and making classes more interesting. A survey was made on the students' previous knowledge about the subject linking some concepts of organic chemistry. After the diagnosis, a sequence of actions was developed for the application of the project. In the practical part, the students helped to set up the small scale plant and the model, and they realized the meaning of researching, designing and also preserving the environment. At the end, the evaluation of the learning methodology was carried out. The results were very satisfactory and it was noticed that the students prefer differentiated classes and projects that involve experimentation related to the content worked in the classroom than the traditional classes. Therefore, the teacher should to strive to enhance his pedagogical practice in order to teach better.
