<b>Implementing cleaner production in an automotive company: an application of material input per unit of service tool to measure environmental and economic advantages

Resumo

Environmental impact reduction has been a growing concern of the automotive industry. One of the main challenges is to implement Cleaner Production as a tool to reduce environmental impacts and provide financial profits. The purpose of this article was to evaluate the environmental impact and economic gains by implementing Cleaner Production, using an unexplored approach, in a company of the automotive sector. The research approach used was a case study, carried out by observation and semi-structured surveys. The production process chosen was updated, so technologies were changed to reduce biotic and abiotic disposal. For the analysis of environmental impacts, the `Material Input Per Unit of Service´ tool (MIPS) was used, in which data was used to calculate: annual net profit; return on investment (%) and return on investment for a period. The results showed that Cleaner Production implementation focusing on changing technology in the production process caused a 75% reduction in environmental impact, and a 62.7% decrease in production costs. Although of this study considers only one case to test the procedure applicability, it can be easily repeated in other more complex systems, by merely making the necessary adjustments due to the complexity of the processes involved.
