INTRODUCTORY BACKGROUND FOR LIFE CYCLE ASSESSMENT (LCA) OF PURE SILK FABRIC

The main goal of this study is to provide an introductory background of the Life Cycle Assessment studies of pure silk fabric. A scenario model for LCA application was developed, following the methodology established by the Standard BNR ISO 14040:2009, which establishes principles and framework for an LCA study. It was considered as one of the first steps in ISO, being the definition of the purpose and scope. The information used in this study was collected directly from the company entitled 'Fio de Seda', a Brazilian industry. In order to construct the scenario proposed, the software Umberto 5.6 v. Acad was used and through it, it was possible to generate the scenario model for the production of the silk fabric. Based on this scenario, the accomplishment of the later stages is possible, as outlined in ISO 14040, thus obtaining the inventory of the LCA for the pure silk fabric, as well as its life cycle inventory assessment.
