Introductory background for Life Cycle Assessment (LCA) of pure silk fabric

摘要

The main goal of this study is to provide an introductory background to development of the Life Cycle Assessment studies of pure silk fabric. There are not studies available on the life cycle of pure silk fabric. In this sense, was developed a scenario model for LCA application, following the methodology established by the Standard BNR ISO 14040:2009, which establishes principles and framework for an LCA study. It was considered one of the first steps in ISO, being the definition of the purpose and scope. The limits considered for the system had as a starting point the wiring step within the company, and as a final limit the stage of the finishing of the fabric, where you get the finished product. 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, was used the software Umberto? 5.6 v. Acad 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.
