Waste Reduction in Pipe Industry Through Lean Six Sigma Implementation

Abstract

This research investigates to manage waste in longitudinal submerged arc welded (LSAW) steel pipes by the utilization of Lean Six Sigma (LSS) tools, with an emphasis on promoting sustainability through waste reduction. The DMAIC approach was implemented to ascertain underlying causes, enact modifications, and oversee practices. Reusing, recycling, and repurposing of materials was employed to minimize production waste. The findings demonstrate a noteworthy decrease in waste with regards to the overall weight of raw material, from 5.3% to 3.4%, and a reduction in monetary losses by 58.07%. The implementation of the LSS methodology has been shown to augment customer satisfaction, minimize waste and variation, and improve sustainability in numerous industries. The effectiveness of the LSS approach in managing waste and promoting sustainability in the LSAW sector was validated by consistent results, as evidenced by the control plan. Given the crucial significance of efficient waste management for sustainable production and consumption, this research underscores the potential of LSS as a resilient methodological approach to reduce waste and advance sustainability in the industry.
