    (Springer Nature, 2026-12) Dilmi, K. A; Sannasgala, S; Weerarathna, R; Rathnayake, N; Pitipanaarachchi, S.M.; Rajapakse, V; Dushmanthi,N; Peemanee, J
    One of significant contributors to the economy of the Sri Lankan economy is the hotel industry which however has its share of environmental challenges such as high consumption of energy, wastage and emission of greenhouse gases. Using Structural Equation Modeling (SEM), this paper aims explores the impact of Monetary Incentives and Green Employee Behaviour as one of the means of promoting green behavior among employees. Adopting a quantitative research design, data was collected through the use of standardized questionnaire, which was applied on 383 Colombo hotel employees. The research attests that monetary incentives positively impact on both in-role and extra-role green behavior and confirms that monetary incentives trigger environmentally friendly work behaviour. The paper reveals the need to develop incentive systems based on the specific socio-cultural and economic realities in Sri Lanka. It also indicates in the study that monetary rewards should be implemented as part of the comprehensive Green Human Resource Management mechanism in motivating long term environmentally sound behavior. The study has implications to hotel policy and managers in that effective monetary incentive schemes can have a role to play in the sustainability of tourism and the environment in Sri Lanka. Future researchers are advised to explore the role of non-financial rewards and assess the long-term sustainability of monetary incentive programmes in fostering green behaviour.

    Circular Economy Practices and Challenges in the Industries of Bangladesh: A Case Study
    (Faculty of Engineering, 2025-09-09) Rashid, I.K.A
    Circular economy (CE) is a concept that represents a paradigm shift from the conventional linear economic model—characterized by the "take-make-dispose" approach—toward a more sustainable framework grounded in the principles of "reduce-reuse-recycle." This transition emphasizes enhanced resource efficiency and the minimization of waste generation. While regions such as Europe and North America have made significant progress in integrating circular economy principles, Bangladesh continues to operate largely within a linear economic framework, exhibiting low levels of recycling and substantial waste accumulation. Circular economy awareness and implementation remain limited across most industrial sectors in Bangladesh, with only a few industries demonstrating preliminary engagement. Nonetheless, the country possesses considerable untapped potential for CE adoption. To investigate the current status and practices of the circular economy in Bangladesh, this study employed semi-structured interviews with key stakeholders across relevant sectors. Additionally, secondary data sources, including annual reports and industry publications, were analyzed to complement and triangulate the primary findings. In this paper, circular economy practices and challenges in a large home appliance manufacturing company of Bangladesh are explored and beneficial guidelines are suggested.

    (Springer Science and Business Media, 2025-01) Perera K.D.Y.G.; Ahamed Y.L.F; Somarathna H.M.C.C; Jayasekara D.A.B.P.M; Mohotti D; Raman S.N
    Electrical distribution and communication cables cease to function for transmission when their length is insufficient, and it is considered as it approaches the end of their useful lives. Further, the disposal techniques are not eco-friendly. This study aimed to evaluate the feasibility of cement mortar systems with the inclusion of aluminium fibre extracted from electrical distribution cables. Two diameters of 1.35 mm and 1.70 mm and two lengths of 10 mm and 15 mm fibres were used while incorporating four volume ratios, particularly 0.5%, 1.0%, 1.5%, and 2.0% to evaluate the effect of the length, diameter and volume ratios. The compression test and density test were performed to study the behaviour of Metal Fibre Reinforced Mortar (MFRM) systems under both dry and wet states. Compared to conventional mortar, the ultimate compressive strength of MFRM systems was increased up to 39.4% in 1.5% of fibre addition under the 28-day dry state, where the 1.5% volume ratio showed the best performance under compressive loads. Strain at ultimate strength, modulus of elasticity and strain energy also showed improvements with the fibre inclusion up to 74.4%, 87.3%, and 106.6% respectively. Fibres with higher aspect ratios showed significant effectiveness among the aforementioned fibre variations. The overall results highlighted that the MFRM with 1.5% of fibres performed expertly with 15 mm length and 1.35 mm diameter under compression loads

    The Green Pulse of Hospitality: Assessing Green Supply Chain Practices on Organisational Performance in the Sri Lankan Hotel Industry
    (Elsevier B.V., 2026-01-03) Bandara R.M.H.N; Ranathunga Arachchi R.A.D.T; Gunasekara L.D.C; De Zoysa N.A.T; Lokeshwara, Anuja A.; Refaie, Chapa S.R.B.
    In the modern competitive business environment, sustainability has become the key theme in organisational performance (OP), compelling organisations to adopt environmentally friendly operations in the business world. The hotel industry is a significant contributor to national economies, and it is steadily incorporating green practices to improve operational efficiency and reduce environmental impact. Though green supply chain management (GSCM) has been a subject of significant interest in manufacturing and logistic settings, GSCM in the hospitality industry, particularly in developing nations such as Sri Lanka, is still a largely unexplored area. To bridge this gap, the current study investigates the relationship between GSCM practices and OP with a particular focus on the moderating effects of hotel star classification. A cross-sectional, deductive research design was used, and Partial Least Squares Structural Equation Modelling (PLS-SEM) was the method of analysis. A web-based survey of 167 star-class hotels in Sri Lanka gained a high response rate of 88.44%. GSCM practices were represented as a second-order construct with five dimensions: eco design, green purchasing, internal environment management, investment recovery, and reverse logistics. The findings reveal that GSCM practices have a significant positive impact on OP. However, the star ratings of the hotels had no significant effect on this relationship, meaning the positive impact of GSCM practices are consistent across the industry. This finding indicates the need to investigate additional moderating variables such as ownership patterns and environmental certifications. Future comparative studies in various Asian nations with different cultural, legislative, and market settings may advance our understanding of GSCM practices in hospitality industry.

    GSCM is one of the most crucial strategies that incorporate sustainability into operational and production practices. Based on this premise, the given systematic literature review examines how the key GSCM practices influence sustainability in Sri Lanka's tea export sector. This review identifies synthesized findings from various studies that the adoption of GSCM has led to a significant improvement in economic sustainability through a reduction in operational costs of up to 20%-and enhancing the ability of market competitiveness. In this regard, environmental concerns contribute by reducing resource consumption by up to 30% as waste is generated, promoting sustainable production processes. Socially, GSCM advances good labor practices and strengthens community involvement in the pursuit of better working conditions, improving relationships between the producers and local communities. With all these advantages, however, GSCM in the Sri Lankan tea export sector faces fluctuating global market prices, effects of climate change, and persistent labor shortages. These challenges are indicative that strategic interventions of the government to support and collaborate in the industry do become urgent to enhance sustainability. This review also points out one important limitation in relying on secondary sources of data and emphasizes that there is a dire need for empirical research to enhance the evidence base to provide actionable insights for policymakers and stakeholders. In sum, this literature review underlined that GSCM played a vital role in the advancement of sustainability within the tea export sector and in providing a competing position of the industry in a global market for long-term viability in sustainability
