Integração do mapa de fluxo de valor com avaliação do ciclo de vida em uma indústria de produtos para pintura

Abstract

This study aimed to promote the integration of value stream mapping and life cycle assessment tools with the aim of proposing improvements in the eco-efficiency of a family of products in an industry in the South of Brazil. The value stream map is one of the tools used in the lean production philosophy that originated in Japan in the Toyota company. This tool has as a principle to map the flow of value of the productive process, since with its construction the process is better seen, and the inventories can be analyzed, which adds value and does not add value to the product, processing times and tool changes , as well as the behavior of the customer, in this case the demand, seeking to generate in this way what is more important for the client. The life cycle assessment, with an environmental purpose, also aims to map a process, where the environmental impacts caused by production are evaluated through the impact categories of greatest relevance to the process. The integration of the two tools occurred from the addition of values referring to LCA, demonstrating the relevant impact categories of the process. These are the depletion of abiotic resources, climate change potential, human toxicity potential. The improvements were proposed based on a built-up plan of action to achieve the goals defined in the future value chain and value flow map, knowing that the future map is the milestones where the company aims to reach. With the proposals presented, a reduction of approximately 20% of the electric energy consumption can be achieved by improving the availability of the injection, rapid tool change and reduction of cycle time and reduction of material used in the product. The work also achieved a reduction of more than 75% in stock of raw material, intermediate and finished product stock. With the two integrated tools, one can achieve better economic, social and environmental results, making companies differentiated in relation to the market. From this, the work sought to present the results that the integration between the main lean and sustainability tools could achieve.
