Benefits of adopting lean production on green performance of SMEs: a case study

Small- and medium-sized enterprises (SMEs) are widely recommended to strive, not only for their performance in operational side, but they need to integrate the environmental dimension. To do that, the literature widely indicates a positive impact of lean practices on green performance. However, very few studies have been carried out in SMEs context. In this view, this paper aims at providing through a practical case study of lean implementation in a real-life small manufacturing company, the information to confirm this synergy between lean and green performance. To achieve this aim, a proposed framework of lean and green integration has been implemented in a SME producing different types of pumps. The results achieved shows that there is a strong correlation between operational metrics improvement and green metrics improvement. Moreover, the benefits of lean practices such as 5S, Kanban, SMED, AM, cellular manufacturing and quality control on green performance are widely demonstrated. Future work could study other processes and explore other case-specific supporting tools and techniques.
