Title in Portuguese
Seleção de fronteiras para análise de ciclo de vida de sistemas que emitem poluentes tóxicos de chaminés
Keywords in Portuguese
Análise de ciclo de vida
Custos de externalidades
Seleção de fronteiras
Abstract in Portuguese
Este trabalho desenvolve um método de seleção de fronteiras para Análise de Ciclo de Vida (ACV) de sistemas que emitem componentes tóxicos. Isto envolve o desenvolvimento de um modelo de predição de concentração e dose de poluentes emitidos de chaminés, que tem a vantagem de ser simples e não requerer grande número de dados de entrada. Esse modelo e mais os dados de valoração econômica de danos ambientais disponíveis na literatura, compõem o modelo geral de estimativa de custos devido à emissão de poluentes, ou seja, a Análise de Custos em Ciclo de Vida (ACCV). O modelo geral é então usado para definir as fronteiras do sistema de ACCV. Demonstra-se a aplicação do novo método em um ciclo de vida hipotético de produção de celulose.

Boundary selection for LCA of systems with toxic stack emissions

Abstract in English
This work develops a method for Boundary Selection (BS) for Life Cycle Assessment (LCA) of systems with stacks emitting toxics compounds. The new approach involves the development of a model of concentrations and dosage of pollutants in the vicinity of emission source that is simple and non-intensive data is required. This model plus impact costs estimations available at environmental economic studies, comprise the general model of Life Cycle Cost Analysis (LCCA) based on exposure. This general model is then used in the Boundary Selection in LCCA. A demonstration of the application of the model is performed to a hypothetical inventory system of a pulp mill.
