Integrating Lean Manufacturing and Sustainable Practices

Abstract

This study examines the application of Green and Lean Six Sigma (GLSS) methods in manufacturing as tools that ensure the sustainable develop ment of a company. The litterature review highlights the trade-offs and synergetic effects of these methodologies and defines the key factors that favor their success. The study addresses critical questions such as the necessity of GLSS implemen tation, what obstacles will arise during implementation and what improvements can be expected in terms of business processes and ecology. This study proposes a conceptual model to help practitioners address specific issues and promote ef fective use of GLSS across a range of manufacturing environments. Furthermore, the study explores the integration of GLSS within the frameworks of Industry 4.0 and 5.0. It highlights the synergies between digital transformation, human-centric innovation, and sustainable operational excellence.This work could form a relevant documentary basis for future research. It also opens up new avenues of reflection for corporate practitioners, providing several practical suggestions for enhancing the use of GLSS and integrating production with environmental requirements.
