This study seeks to evaluate operational improvements in Brazilian petrochemical company Braskem, which
has been using lean production management tools to monitor its processes. There was some improvement in
plant efficiency, measured from the beginning of implementation of management tools Six Sigma and TPM.
Thus, we investigated three efficiency indicators considered by the company of great importance for the
competitiveness of the business: the physical loss of products, plant’s energy efficiency, and the utilization
rate of assets. The differences observed in these indicators, before and after the use of the tools, were tested
for its statistical significance, which revealed that the physical losses of ethylene and plant’s energy
efficiency improved, almost reaching the performance considered as class world. As for the utilization rate
of assets, although it has evolved positively, still is at a considerable distance from that performance
standard. By registering operational improvements in a continuous process plant, with lean production
tools, this study indicates that these instruments, even if they have no causal relation with the improvements,
are suitable for continuous processes and could have a much broader use, oriented, first of all, by the
general approach of process optimization and, somehow, regardless of the nature of productive activity.
