Adoption of Green Supply Chain Practices in Manufacturing Companies in Sri Lanka
(Staff Development Center, University of Kelaniya, 2015) Jayarathna, B.C.P.
The concept of Green Supply Chain Management is being discussing by the researchers today more than ever before. It is because of environmental issues raised through the process of delivering the products to end user. It becomes one of the main sources of serious environmental problems. Therefore most of the organizations tend to accept the green practices as a concern to environmental sustainability. Therefore this study aims to identify the level of adoption of green supply chain practices of manufacturing firms in Sri Lanka and to identify the key derivers that influence to adopt green supply chain practices of manufacturing firms in Sri Lanka. For this purpose structured questionnaire is used to collect data from the sample of ISO 14000 certified manufacturing companies in Sri Lanka and structural equation model is used to analyze data. Theoretical scope of the study includes identifying external factors based on institutional theory and internal factors based on resource based view for adopting green supply chain practices while empirical scope is narrow down to the manufacturing companies of Sri Lanka. Identifying the trend that the world need to be changed for environmental aspects due to global issues, it is important to study the green supply chain management since it is one of the ways to reduce environmental impacts of firms’ operations and for sustainability. And also the findings of the study will be more contributed to enhance the adoption of green supply chain practices by manufacturers, suppliers and the government.
Building a Conceptual Model for Adopting Green Supply Chain Practices
(2015) Jayarathna, B.C.P.
Green supply chain management is becoming more popular in South East Asian region and it is a way to display the genuine commitment to sustainability of any organization and the environment in this region. Most of the developed and developing countries tend to adopt green supply chain practices as a solution for serious environmental problems. Therefore this study supports for the potential organizations to adopt green supply chain practices and strengthen the extant body of knowledge on green supply chain management. This paper presents a conceptual model for identifying the key drivers that influence to adopt green supply chain practices based on the existing literature. The proposed model addresses the key drivers as external and internal factors based on theoretical background of institutional theory and resource based view theory. It is expected that proposed model will be more contributed to enhance the adoption of green supply chain practices by manufacturers, suppliers and government.
Conceptual Model for Moderating Effect of Firm Size on Institutional Pressures and Green Supply Chain Practices Adoption
(Faculty of Commerce and Management Studies, University of Kelaniya, 2015) Jayarathna, B.C.P.
The concept of Green Supply Chain Management is highly discussed and drawn more attention in contemporary world today. The need of sustainable environment and sustainable organization motivates to draw more attention on Green Supply Chain Practices. Realizing this phenomenon number of researchers developed models to measure the effect of pressures on green supply chain practices adoption. In this study pressures on green supply chain practices are identified as normative pressures, coercive pressures, and mimetic pressures based on institutional theory. Previous studies showed that institutional pressures have significant effect on adopting green supply chain practices. But no single research in supply chain management field to study moderating effect of firm size on pressures and practices of green supply chain management. Therefore this study aims to provide conceptual model to test the moderating effect of firm size in the relationship of institutional pressures and green supply chain practices adoption by filling the identified gap. It is expected that proposed model will be more contributed to enhance the adoption of green supply chain practices by different size of manufacturing companies.
An Integrated Model for Green Computing towards Sustainability
(9th International Conference on Business and Information (ICBI-2018), Department of Management Studies and Toc H Institute of Science and Technology, India, Faculty of Commerce and Management Studies, University of Kelaniya, Sri Lanka, 2018) Jayarathna, B.C.P.
The concept of Green Computing is widely taken into consideration by both local and global computing industry due to serious environmental issues such as global warming, high energy consumption, and e- waste. Thus the global community strongly believe that Green computing contributes to solve these environmental issues and achieve sustainability. However it is doubtful that, does green computing really contributes sustainability since there are lack of scholarly evidence. Therefore this study aims to propose an integrated model for green computing towards sustainability in order to identify how green computing contributes to achieve sustainability. In that model green computing is recognized as four major stages as Green design, Green manufacturing, Green use and Green disposal while sustainability is indicated with three major aspects as economic, environment and social performance. Since there are some vacuum of experimental research in the field of green computing towards sustainability and the existing studies were more focused on only environmental impact of green computing rather balancing all three dimensions of sustainability, the researcher concludes that proposed model will be more reasonably addressed the sustainability in the field of green computing by addressing all three aspects of sustainability including environment, social and economic
