While it is understandable that lean and green practices are mostly sensible for large companies, it is also important to bring these practices to small and medium enterprises (SMEs), as they are the dominant players in various industry sectors. SMEs are part of larger supply chains and contribute substantially to the economy, and thus perhaps there is a need for a workable model that attracts them to the lean and green practices. This study aims to find gaps in the lean-green research area that require development in future studies, especially for SMEs. This study uses an analysis of systematic literature reviews (SLR) and involves carefully selected articles from different databases or sources. This SLR was conducted in an effective and structured way using keywords entered into the search engine and found as many as 157 peer-reviewed journal articles, which were studied further using quantitative and qualitative approaches. The bibliometric analysis carried out made it possible to observe research trends on lean and green from 1996 to 2022. To find different research dimensions on lean and green topics, an in-depth evaluation was carried out on the linkage between lean, green, supply chain management, sustainability, and other management approaches. This study finds a lack of empirical research studies that comprehensively focus on investigating the impact of lean and green practices on the supply chain sustainability performance of manufacturing SMEs and involve all three aspects of the triple bottom line (3BL). Our review suggests such a robust and workable model for SMEs is not currently available. A limitation of our review is the use of keywords or “terms” to select articles, as well as the subjectivity of the researcher. Finally, we identify the research streams, criteria, findings, limitations, and enablers or challenges of 17 selected published journal papers on lean-green studies in SMEs and propose a number of research questions for future research directions.

This paper describes how to apply both of value stream mapping tools and kanban system for identifying and reducing wastes that happened on shop-floor. This research was conducted at a basic chemical company which produces the thinner. This study aims to reduce even to eliminate the types of waste that occur on the production line of jerrycan product type. The plot of VSM is used to picture the entire of value stream. The value stream mapping tools are used to analyze the certain waste after it has been figured out by using waste assessment model. Hence in this study two selected tools were applied and discussed further, i.e. process activity mapping, and supply chain response matrix. The Current-VSM shown that value-added time of 472.33 s compared with total lead time of 132,568.76 s, consequently obtained process cycle efficiency (PCE) approximately 0.36%. Kanban system will be implemented to eliminate waste of unnecessary inventory throughout the value stream. At last, the result of improvements shown that value of PCE probably will increase by 67.25%, non-value activity will reduce 6.74%, as well as order fulfillment time of the whole process will be 13 days with 3.59 days of physical stock.

In recent years, every manufacturing industry has tried to eliminate various wastes in its operations. The effect of wastes will have a direct impact on increasing costs. Therefore, the cost approach is integrated into the value stream mapping to obtain an illustration of the cost losses incurred. This paper describes how to apply integrated value stream mapping with the cost approach. Finally, this approach is considered effective in mapping the amount of cost losses incurred due to the wastes that occur along the value stream.

Today, competition between supply chains occurs and the existence of SMEs as one of the players in the supply chain cannot be ruled out. In order to win the competition, all supply chain players must have the same direction and objectives. Lean-Green and Sustainability practices have been applied to large companies and provide benefits. However, to the best of our knowledge, only a handful of studies have addressed Lean-Green and Sustainability practices in the SME context. The literature review found that there is a lack of comprehensive empirical research studies investigating the impact of Lean-Green practices on the sustainability performance of SME supply chains. Thus, this paper proposes a conceptual model that is expected to provide an overview of the Lean-Green concept and the sustainability of the SME supply chain for further empirical study in developing deeper knowledge about these two practices.
