A produção agrícola de tabaco (Nicotiana Tabacum) brasileira através da perspectiva de avaliação de ciclo de vida.

Abstract

Characterized as one of the biggest Brazilian commodities, tobacco (Nicotiana Tabacum) generated, in the 2018/2019 harvest, R $ 6 billion in assets from exports, with 664,355 tons of dry tobacco produced and 149,060 families involved in the agricultural production chain. Being an important economic and social contribution, the present study used the approach of life cycle assessment (LCA) in order to quantify the potential environmental impacts of the stages of agricultural tobacco production. Through an inventory with regionalized data and primary origin from 25,000 tobacco growers in the southern region of Brazil and sampling of atmospheric emissions collected on the spot, it was possible to establish the life cycle inventory of dry tobacco at the door of the processing plant . The computer programs Umberto NXT LCA, Umberto LCA + and SimaPro were used, and the carbon footprint (IPCC 2013) and Recipe® 2016 v1.0. Indicators were selected as ACV indicators, with the midpoint and endpoint approach, applied to the quantification of potential environmental impacts of conventional and organic cultivation techniques and insertion of atmospheric emissions data for the curing stage. This was the first Brazilian study to identify the environmental hotspots of tobacco cultivation in its agricultural phase and to use primary tobacco planting data from the southern states of Brazil, where Brazilian production is concentrated.
