RESUMO

This work aims to show the efficiency of Six Sigma Methodology application in reducing waste of a manufacturing process. The making process of disposable respirator was chosen to this case study because it generated an enormous amount of fiber scrap used as raw material. Improving methodologies applied every since had reduced significantly the waste level but a different approach was needed to reduce it even more. Following the Six Sigma Methodology, a team was formed to focus the whole attention on reducing this waste and breaking the paradigm which inherent waste of a process cannot be eliminated. Through an addition of a new process step in order to reprocess the waste ? pressed fiber discharged by the end of this process - all of it was recovered, keeping the same characteristics of raw fiber. Therefore, the waste was 100% eliminated. Sigma level, which was historically lower than 3, became higher than 6 by the end of the work. The statistics tools applied demonstrated the optimized set point of the raw and recovered fiber mixture in order to maintain the final product properties under the point of view of end-users. This work resulted in team technical development and precious non-renewed raw material savings
