Exploring the Challenges of Integrating Lean Green Practices in Industry 4.0 Manufacturing Frameworks: An Empirical Study

In the era of Industry 4.0, the Lean Green approach stands as a beacon of environmental sustainability and waste reduction within manufacturing processes. This study delves into its implementation dynamics within the Indian manufacturing landscape. Employing a comprehensive methodology, a widespread questionnaire survey was conducted across companies to gauge and rank barriers hindering seamless integration. The analytical framework, structured around a three-tier hierarchy diagram, leveraged the Analytical Hierarchy Process (AHP), a renowned Multi-Criteria Decision Making (MCDM) technique. Through this systematic approach, insights were gained into pivotal barriers, with employee motivation emerging as the linchpin for driving Lean Green initiatives. Lack of motivation surfaced as the most salient barrier, significantly impacting operational efficacy. These findings underscore the critical importance of addressing motivational factors to propel sustainable manufacturing practices amidst Industry 4.0 advancements.
