Implementation of green, lean and six sigma operations for sustainable manufacturing. A review

Abstract

With ever increasing environmental concerns and global warming, green manufacturing has gained momentum to make the manufacturing processes sustainable and efficient. This review aims to analyse the models to integrate three different management systems that are green, six sigma and lean for the sustainability of various manufacturing processes. Research gaps for such integration are identified through a literature review of various studies. The importance of the concepts of eco-friendly and sustainability in business operations and practices is growing rapidly as a result of public pressure, government regulations and social responsibilities. The first step is the identification of sustainability assessment for the current industrial processes and then to make them eco-friendly and more efficient through different green, six sigma and lean tools available. The methodology presented in this review will not only help in sustainability but also is helpful in the integration of various models for the improvement of the processes. Green Lean Six Sigma (GLS) is an approach known to minimize emissions and carbon footprints while improving process efficiency. GLS includes green, six sigma and lean methodologies for high performance, sustainability, social development, economic progress and environmental protection. The successful integration of this GLS approach is dependent on different theoretical indicators and the model is developed based on DMAIC. Various tools, enablers and integration methods are employed for the GLS approach.

Effect of lean six sigma and recent technologies on environmentally sustainable manufacturing and financial management practices

“…The proposed study highlights the significance of continual improvement and continuing assessment to pursue sustainable manufacturing processes. It is in line with the existing research studies (Ganjavi & Fazlollahtabar, 2021;Nagadi, 2022;Shokri, Antony, & Garza-Reyes, 2022;Shokri & Li, 2020). Organizations may improve their methods and create more sustainable, environmentally friendly operations that benefit their bottom line and the globe through increased research and experimentation.…”

“…Letchumanan et al (2022) and Shokri et al (2022) emphasized the capacity of AI and big data analytics to enhance financial efficiency, minimize expenses and enhance overall financial performance. The current literature on LSS and RT mostly examines their effects on sustainability and financial management through the use of case studies, surveys and theoretical frameworks (Ganjavi & Fazlollahtabar, 2021;Nagadi, 2022;Raval, Kant, & Shankar, 2019;Shamsi & Alam, 2018;Shokri & Li, 2020;Sreedharan & Sunder, 2018;Trakulsunti, Antony, & Douglas, 2020;Wahba, Kamil, Nassar, & Abdelsalam, 2019). On the other hand, the proposed study employed quantitative analysis to investigate how the combination of LSS with modern technology affects manufacturing in real-world situations.…”

Green Lean Six Sigma model for waste reduction of raw material in a nectar manufacturing company of Lima, Peru

“…In the literature it is possible to find several studies on Green Lean Six Sigma because the combination of Green, an approach used in operations that considers the environmental impacts of production (Deif, 2011); with Lean, which maximizes the flow of the process and the delivery time since it reduces waste; and Six Sigma, since it recognizes and reduces existing variations in processes (Kazancoglu, Kazancoglu & Sagnak 2018); produces a powerful strategy that is capable of obtaining better results in environmental objectives (Garza-Reyes, Torres-Romero, Govindan, Cherrafi & Ramanathan, 2018). Researchers such as Kaswan and Rathi (2020), Gholami et al (2021), Mohan, Rathi, Kaswan and Nain (2021), Yadav, Gahlot, Rathi, Yadav, Kumar and Kaswan (2021), Nagadi (2022), Gaikwad and Sunnapwar (2021), Rathi, Kaswan, Garza-Reyes, Antony and Cross (2022) and Sreedharan, Sandhya and Raju (2018) have developed GLSS models in different industries such as manufacturing, public sector, etc. However, the literature specifically on the food or agri-food industry is non-existent, because after a rigorous investigation, no work was compiled; therefore, the value of our article resides in this problem because it fills the academic gap.…”

Lean and Green Decision Model for Lean Tools Selection

“…On the other hand, green manufacturing is a production approach that should affect the entire product life cycle to increase the energy efficiency of the process and reduce the environmental impact of the product [11]. While lean manufacturing positively impacts the economy by eliminating various types of waste from the value creation process, the green approach focuses on environmental and social factors by promoting energy-saving practices, recycling, and the reuse of products [12]. It is evident that the collaborative integration of lean and green manufacturing holds the potential to generate a positive impact across all three dimensions of sustainability: economic, environmental, and social.…”
