Item Product and Process Characteristics for Green Manufacturing: Evidence From Indian SMEs(ASME, 2011-04) Sangwan, Kuldip SinghWith growing awareness of environmental issues — from global warming to local waste disposal — business and government have come under increasing pressure to reduce the environmental impacts involved in the production and consumption of goods and services. However, organizations consider environmental assessment fairly late in the product development process, which generates additional design constraints and increases the development costs. The integration of environmental requirements through life-cycle stages of a product is a likely approach, leading to a new paradigm of green manufacturing. Empirical studies by various authors have indicated that Small and Medium Enterprises (SMEs) find it difficult to implement environmental issues in product and process design because of lack of time, resources, expertise and/or framework in comparison to large enterprises. This paper presents the results of an empirical study carried out on Indian SMEs to develop product and process characteristics of green manufacturing. Fifteen product and four process characteristics have been developed to be considered during the product and process design to address the environmental issues for the life cycle of the product. These characteristics provide an easy to use self assessment framework to the SMEs to address the various environmental issues during the product and process design. The characteristics identified from the literature have been validated by using SPSS for Windows statistical tool. The reliability and validity of the data has been assessed by the Cronbach alpha and factor analysis respectively.Item Employee involvement and training in environmentally conscious manufacturing implementation for Indian manufacturing industry(IEEE, 2014) Sangwan, Kuldip SinghEmployee involvement and employee training are most important and vital principles for the successful implementation of any newer manufacturing system or modern practice in any organization because the newer systems/practices require changed roles for people at all levels. The general human tendency to resist change understood properly may lead to dysfunctional implementation of newer systems/practices. Environmentally conscious manufacturing (ECM) being a new paradigm in manufacturing requires the changed roles for employees. The management must have measures to convince the shareholders that the plan to implement ECM has taken care of changed roles of people. This paper identifies the employee involvement and employee training measures for the successful implementation of ECM. The identified measures have been validated by a case study of Indian large scale enterprises. The measures identified from the literature have been validated by using SPSS for Windows statistical tool. The reliability and validity of the data has been assessed by the Cronbach alpha and factor analysis respectively. The results provide sure evidence that the identified measures are highly reliable and valid.Item Management Commitment and Employee Empowerment in Environmentally Conscious Manufacturing Implementation(WCE 2011, 2011) Sangwan, Kuldip SinghManagement commitment and employee empowerment are most important and vital principles for the successful implementation of any newer manufacturing system or modern practice in any organization because the newer systems/practices require changed roles for people at all levels. The general human tendency to resist change understood properly may lead to dysfunctional implementation of newer systems/practices. Environmentally conscious manufacturing (ECM) being a new paradigm in manufacturing requires the changed roles for top management, middle management and employees. Therefore the managers must have measures to convince the shareholders that the plan to implement ECM has taken care of changed roles of people. This paper identifies the top management commitment, middle management commitment and employee empowerment measures for the successful implementation of ECM. The identified measures have been validated by a case study of Indian large scale enterprises. The measures identified from the literature have been validated by using SPSS for Windows statistical tool. The reliability and validity of the data has been assessed by the Cronbach alpha and factor analysis respectively. The results provide sure evidence that the identified measures are highly reliable and validItem Development and validation of performance measures for environmentally conscious manufacturing(Inder Science, 2013) Sangwan, Kuldip SinghGrowing awareness of environmental issues has put business and government under pressure to reduce the environmental impacts involved in the production and consumption of goods and services leading to a new paradigm of environmentally conscious manufacturing (ECM). However, because of the lack of ECM performance measures, judgements about ECM have become costs in ethical or moral terms. In this paper, 11 performance measures for environmentally conscious manufacturing have been identified based on the review of 78 research papers/articles and discussion with practitioners. A survey of 285 industries in India, using a questionnaire specifically developed for this study, has been done to validate the identified performance measures. The developed performance measures have been found to be highly reliable using Cronbach’s alpha. The validity of the performance measures has been assessed through factor analysis by using SPSS 11.5 for window® statistical tool.Item Quantitative and Qualitative Benefits of Green Manufacturing: an Empirical Study of Indian Small and Medium Enterprises(Springer, 2011) Sangwan, Kuldip SinghGreen Manufacturing (GM) has attracted the attention of organizations all over the world. However, managers, who are considering the introduction of GM in their organizations not only have to identify the application and plan its implementation but also have to ensure that the use of GM will be a viable alternative. Most critical issue with the industry, particularly with SMEs before implementing GM is what benefits will be achieved with its implementation. This paper identifies the quantitative and qualitative benefits of GM through a literature survey. A survey of 198 Indian SMEs in India, using a questionnaire specially developed for this study, has been done to validate the benefits by using SPSS statistical tool.Item Development of a structural model of environmentally conscious manufacturing drivers(Emerald, 2014-09) Sangwan, Kuldip SinghManufacturing firms consume energy and natural resources in highly unsustainable manner and release huge amounts of green house gases leading to many economic, environmental and social problems; from local waste disposal to climate change. Consciousness about these issues has lead to a new manufacturing paradigm of environmentally conscious manufacturing (ECM). There exist many social, legislative, policy, economic, internal, and environmental factors which can motivate and/or force industry to adopt ECM. The purpose of this paper is to identify the drivers for ECM, developing a model of these drivers using statistical analysis and testing the model using structural equation modeling (SEM) technique.Item Ranking of Drivers for Green Manufacturing Implementation Using Fuzzy Technique for Order of Preference by Similarity to Ideal Solution Method(Wiley, 2014-07) Sangwan, Kuldip SinghThe governments are under tremendous pressure to sustain high manufacturing growth in emerging economies. Unfortunately, the manufacturing sector consumes much energy and other resources and emits a large amount of green house gases, which increases environmental problems such as climate change and global warming. One possible solution to this problem is green manufacturing (GM) implementation in industry. However, GM implementation faces many challenges. Various motivating factors named as ‘drivers’ should be facilitated by the government and industry to make this change possible. This paper investigates the drivers for GM implementation and their ranking based on fuzzy technique for order of preference by similarity to ideal solution method using government, industry and experts perspectives. The study concluded that competitiveness, incentives, organizational resources and technology are top ranked drivers and should be facilitated by the government and industry to help implement GM. The ranking of these drivers is expected to help the government and industry to focus on few important drivers to facilitate the GM implementation with limited resources.

A growing number of organizations have begun or are willing to work towards implementing Green Manufacturing (GM) in these nations. But the adoption of GM is a challenge for the organizations in these nations as motivating factors (drivers) are not facilitated and inhibiting factors (barriers) are not mitigated, which pose a heavy burden. This paper aims to statistically analyze the drivers and barriers to GM implementation for developed and emerging nations so that the organizations can strategically focus on these factors to reach to a higher level of competitiveness. This study will help decision makers in manufacturing organizations and in policy of both nations to strategically leverage the collaborative efforts by effective implementation of GM.Item Adoption of Integrated Lean-Green-Agile Strategies for Modern Manufacturing Systems(Elsevier, 2017) Sangwan, Kuldip SinghEver increasing customer choices, environmental concerns and competitiveness among manufacturers across the globe has engaged the industry to embrace newer manufacturing strategies. Predominantly, there are three dimensions to modern manufacturing systems viz. economic, environmental and social. The integration of lean-green-agile manufacturing strategies would be a complete and comprehensive manufacturing system which is the need of the 21st century. The adoption of Lean-Green-Agile Manufacturing System (LGAMS) would be facilitated by few enablers. The influence of these enablers is a matter of investigation which is addressed by the present study. An attempt has been made to prioritize the facilitating capacity of each enabler. The outcome of the research would facilitate the policy makers in the industry and government to frame policies.Item Prioritizing Drivers for Green Manufacturing: Environmental, Social and Economic Perspectives(Elsevier, 2014) Sangwan, Kuldip SinghThe governments are under tremendous pressure to sustain manufacturing growth particularly in emerging and developing economies to improve quality of life of their citizen. Unfortunately, the manufacturing sector consumes lot of energy and other resources and emits large amounts of green house gases which increase environmental problems like climate change and global warming. One possible solution to this problem is green manufacturing (GM) implementation in industry. However, GM implementation faces many challenges. Government and industry should provide motivation to make this change possible. This paper aims at prioritizing these motivating factors based on fuzzy TOPSIS method using environmental, social and economic perspectives. The prioritization is vital for the emerging and developing economies because of the limited financial and other resources. The prioritization of GM drivers is expected to help the government and industry to focus on few vital drivers to facilitate the GM implementation.
