Emissões dos gases de efeito estufa do ciclo de vida da soja cultivada em uma localidade em Caçapava do Sul - RS

Abstract

The world population growth has influenced the significant increase in soybean production. This results in several social and environmental impacts, mainly related to global warming, being necessary to make a research by methodologies that help in the identification and accounting of them. The life cycle assessment is a strategic environmental management tool that which assists in the identification, quantification and evaluation of the environmental impact of all the production cycle of a product or process, from the purchase of raw materials, production, use, post-use treatment, recycling until final destination. In this work, it was identified and quantified the main stages and the inputs present in the soybean cultivation in a locality in the city of Caçapava do Sul, so that it was possible to estimate the emissions of greenhouse gases. It was concluded that the cultivation of soybean is relevant to the impact of global warming, with the value equal to 0,73 kgCO2eq/kg soybean harvested, being that the main sources of emission are derived from the application of limestone in the soil, production of inputs, especially the herbicides and the transport of the inputs to the place of study.
