RESUMO

In view of that some environmental problems are associated to the industrial production, it becomes necessary to work and to apply concepts for the sustainability. Spite of complex system its possible to accomplish an analysis for the sustainable development through method that support to obtain data and interpretation of the results. Life Cycle Assessment can be considered one of the most appropriate, that because it propose solutions for global environmental problems, once it includes all of the stages of the life cycle of a product or process, from: the extraction and processing of raw materials, production and packing, transport and distribution, use and recycling until the final disposition. LCA studies comprise four phases: the goal and scope definition, inventory analysis, impact assessment and interpretation the results. The objective of this research is to propose an appropriate systematic to accomplish the Inventory of Life Cycle Assessment for the Tampa de Relê EM that its injected with a blend of poly (phenylene oxide) and polystyrene of high impact (PPO/PSHI), to support in a subsequent Life Cycle Assessment studies. This research was structured in the following stages: the goal and scope definition; analysis of the processes; obtaining of data for inventory analysis; impact assessment and interpretation the results, characterization of the material and mechanical and physical/chemical analyses. The inventory was accomplished considering all the inputs and outputs of each stage of the system in analysis and starting from the obtained data, they were identified the aspects and impacts environmental associates to it. The main environmental impacts obtained were the exhaustion of natural resources, contamination of the soil and atmospheric pollution. The analyses done in the virgin material and recycled, presented similar results in thermal resistance and properties mechanics and physical/chemical.
