BIOFUELS
STATUS QUO AND FUTURE CHALLENGES – A REVIEW
Palavras-chave:
sustainability, waste recovery, first generation biofuels, second-generation biofuels.
Resumo
The major international agencies that check the development of society warn about the energy model of the current world, pointing the need of substitution by renewable sources of energy. This condition becomes even more worrying when
perspectives point to a world population of 9 billion people in the next decades and the demand for food that will need. Therefore, competition for fertile land to nutrition and energy ends is already clear today. Bioethanol, a biofuel capable of partially replace gasoline for the high productivity reached, uses mostly renewable sources of energy as sugar cane and corn, increasing the price of these raw materials. New sources for ethanol production are being researched to make it a second-generation biofuel, competitive but not affecting the food production, like animal fatty wastes and inedible oilseeds. This applicability of using wastes and effluents to produce second-generation biofuels is gaining strength in the scientific community and they conduct researches to optimize and expand the scale of production of biofuels from these sources. In this review, we approach the processes used today to produce biofuels, the problems and the new possibilities to break the barriers that hinder this large-scale sustainable production.
