Lean manufacturing is a strategic tool, which is used to cut down waste and to improve the efficiency of an organization and helps the organization to sustain in the competitive environment. Implementation of green systems in organization results in reduce energy consumption, waste generation, and hazardous materials used while also building the companies’ images as socially responsible organizations. Several research efforts discussed in the literature indicate that lean companies show significant environmental improvements by being more resource and energy efficient. Lean and green systems are associated with waste reduction techniques. In foreign, many industries have started implementing these concepts and they are getting good results. In India, companies are facing problems in implementing lean and green concept. This paper investigates critical success factors for lean and green system implementation in Indian medium scale manufacturing industries. The factors are grouped into different levels by Interpretive Structural Modelling (ISM)

In the literature arena, it is claimed that lean manufacturing has been implemented successfully in organizations. However, lean manufacturing has been finding little application in classical manufacturing organizations. A careful study of the literature would indicate that non-value adding activities have been occurring in classical manufacturing organizations and preventing the successful implementation of lean manufacturing. In order to overcome this deficient situation, the research reported in this paper was carried out. By carrying out this research, non-value adding activities were mapped with lean manufacturing strategies. In the beginning, 50 non-value adding activities and 27 lean manufacturing strategies were gathered from the literature arena. Through critical thinking, the non-value adding activities were mapped with lean manufacturing strategies. The list containing this map presented in this paper will be useful to the engineers and managers for successfully implementing lean manufacturing in classical manufacturing organizations.

Change is the word that best characterizes the nature of modern Business scenario and determines the challenges that manager’s face.Staying competitive requires looking for new ways of reducing costs and increase the quality of the company’s products. Lean thinking is considered to be one potential approach for improving organizational performance.When the flexibility seems to be an important issue in today’s highly competitive environment Lean integrated as a complete system in the organization can ensure company’s adaptation. Developed as a production system eliminating wastes in the Toyota’s plants in the 1960’s, Lean is evolving into a management approach that improves all the processes at each level of an organization. This study aims to develop a comprehensive theoretical framework that suggest a detailed perspective of the Lean manufacturing to the managers whoconsider implementing it as a possible direction towards achieving sustainable performance for their organizations. The factors which affect the implementation of lean in manufacturing sector are identified by undertaking extensive literature review and consulting the experts from academia and industry. The factors identified are modeled to find the respective loading on Lean variable using Structural Equation Modeling.

In landfill, it was found that the majority of the plastic items are not biodegradable and very gradually degrade. With reprocessed consumer plastics, many attempts have been made to reduce the impact on the environment and to avoid the consumption of virgin plastics. The plastic blend of 50% reprocessed high density polyethylene (HDPE) and 50% virgin HDPE has been used purposely for this study. Usability of reprocessed HDPE as alternative for virgin HDPE is investigated. This paper investigates the influence of the process parameters melt temperature, holding pressure, and cooling time on tensile strength and flexural strength through Taguchi methodology and grey relational analysis in Injection moulding machine. Multi response characteristics like tensile and flexural strengths are selected to evaluate the process performance and the corresponding moulding parameters of the melt temperature, holding pressure, and cooling time. Optimal combination of injection moulding parameters is determined using Taguchi and Grey relational analysis. Tensile and flexural strengths of the reprocessed HDPE are found close to that of virgin HDPE. Hence, reprocessed HDPE is found a good alternative for virgin HDPE. The confirmation results reveal that, there is significant progress in tensile strength and flexural strength of reprocessed HDPE and Grey relational grade are improved by 6%, 5% and 74% respectively. Optimal combination of the process parameters for the multi-performance characteristics of the reprocessed HDPE is the set with melting temperature at 235 °C, holding pressure at 250 N/m2 and cooling time at 25 s.
