Avaliação ambiental do cultivo de Aleurites fordii Hemls : através da análise do ciclo de vida.

Abstract

Conventional agriculture over the past decades has been facing serious crises caused by numerous factors ranging from inadequate soil management, to the excessive application of pesticides. Thus, alternative production systems have been developed, among which are agroforestry systems, especially those that coalesce to produce energy in its context. With the objective of this study was to environmentally evaluate the culture of Aleurites fordii Hemls. produced in agroforestry systems, through the methodology of Life Cycle Analysis using software SimaPro 7.3.2. As a result it was found that the major category of environmental impact is the use of the soil, where they are considered the removal of species of flora and fauna and the ecosystem changes. The full impact of this category was 1741.218 m² yr-1 Potentially Disappeared Fraction (PDF * m²yr-1). Among the three stages of the production process, the first, Seedlings Planted, accounts for 95.26% of the total impacts associated, falling 4.74% for the remaining steps of the Fruit Harvest and Driving. Thus, it is concluded that such step which concentrates the majority of environmental impacts is executed only once every thirty years, because the culture has a perennial production cycle, the production process is considered a less impressive than cultures annual general.
