摘要

In the next decade the Brazilian demand for ethanol will be 60% higher thancurrent consumption. The volume of sugarcane production is expected to increase furtherexpanding the crop, especially to regions such as the Midwest of Brazil. At this site, the soilsare predominantly acidic and with low natural fertility, which require application offertilizers to favor the development of production. However, could this practice causeenvironmental effects in the future? Therefore this article aims to measure the potentialenvironmental impacts generated of fertilizers to expand sugarcane production by 2050. Theapproach considers the elementary flows of processes according to the principles of LifeCycle Assessment (LCA). Fertilizer exploitation uses the macronutrients of fertilizers,nitrogen (N), phosphorus (P) and potassium (K). The database considered comes fromEcoinvent v.3.3 and application of the CML 2000 method for impact assessment. The majorcontribution of substances are generated by the leaching process to either N or P, identifiedby sensitivity analysis. The emissions of K are not mentioned by their absence of isolatedcontribution. The results show that the regions of sugarcane expansion will widen the acidityof your soil. The origin of the environmental impact indicates that the processes of nutrientapplications must be controlled to provide sustainability to the growth of sugarcaneproduction in Brazil.
