Title: Avaliação do ciclo de vida energético do processo de fabricação de embalagens metálicas: Estudo de caso para latas de bebidas
Abstract: The environmental consequences of increased energy consumption bring climate change and global warming.The rational use of energy becomes a key word for global sustainable development.The industrial sector is the most energy-consuming sector in the world and in Brazil, where the food industry is the segment with the highest energy consumption index.The Life Cycle Assessment (LCA) is a key step towards sustainable management.Despite the popularity of ACV in the field of metallic beverage packaging, there is a lack of studies regarding the production system of these.While LCA evaluates impacts in a general way, a derivative analysis, called Energy Life Cycle Assessment (LCEA), focuses on energy as the only measure of environmental impact.ACVE has been used in the last decades in the industrial sector due to efforts directed at increasing energy efficiency.The objective of this work is to use ACVE to quantify the energy consumption of a metallic beverage packaging manufacturing plant by means of an exploratory case study method, aiming to provide greater familiarity with the problem addressed.For this purpose, the data was collected in an industry of aluminum packaging for beverages.The work presented an analysis in relation to all stages of the productive process investigated in order to demonstrate its consumption of thermal and electric energy.It was verified that the energy balance in the process of production of aluminum cans presents as predominant source of energy the electricity (57.7%).However, although thermal energy is applied in only three steps throughout the process, it has an expressive participation (42.3%).The total energy consumption in the process was 105,021 kJ per 1000 produced packages.
