Particularly, a sector which can play an important role to reduce the impact on the environment through the life cycle thinking is the beverage packaging. In this context, the aim of this study was to use the life cycle assessment （LCA） method to investigate the consistency of the preference order across two alternative beverage packages through the application of two impact assessment methods, namely the IPCC 2007 which is focused on the GHG emissions estimation and the EcoIndicator 99 which considers several environmental categories including impact on climate change. The results showed that the life cycle approach employment was a useful strategy to investigate the consistency of the preference order across two beverage packages, especially, whether the results are made more reliable by the utilization of primary data. The investigation on climate change conducted on two level, initially, the quantification of the GHG emissions and secondly the estimation of the related diseases and mortality, demonstrated that the laminated carton presents lower impacts than the high-density polyethylene （HDPE） bottle.展开更多

The life cycle assessment （LCA） is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the ＂returns＂ to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks： glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.展开更多
