Lean thinking for a green tomorrow: evaluating the environmental impact of lean manufacturing with a focus on innovation culture in the South Indian food processing industry

This study aims to investigate the impact of lean manufacturing practices (LMP) on environmental performance (EP) in the food processing industry in South India, with the moderating role of innovation culture (IC). This study assesses how lean manufacturing practices implementation, emphasising waste reduction and process optimisation, influences the environmental footprint of food processing operations. The study conceptual model is based on diffusion innovation theory. The data was collected from owners and managers. The data was collected through a structured questionnaire survey of 265 food processing industries located in south India. the descriptive analysis through SPSS and hypothesis testing through SmartPLS. additionally, this study performed process macro analysis and IPMA analysis. The results indicate that lean manufacturing practices positively influence environmental performance. Innovation culture positively moderates the relationship between lean manufacturing practices on environmental performance. Findings aim to provide insights into the interplay between LPM, IC and EP, providing valuable implications for practitioners, policymakers, and academics striving to enhance sustainability practices in the dynamic landscape of South India's food processing industry.
