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.
Smart Irrigation System Using Arduino and LabVIEW for Real-Time Monitoring and Efficient Water Management
(Faculty of Engineering, 2025-09-09) Vinayagamoorthy, S
Efficient water management is a critical challenge in agriculture, particularly in regions experiencing water scarcity and climate variability. Conventional irrigation systems, typically based on fixed
schedules or manual practices, often result in over- irrigation or under-irrigation, leading to resource wastage and reduced crop performance. This paper presents the design and implementation of a Smart
Irrigation System that integrates Arduino-based embedded hardware with a LabVIEW graphical interface to achieve real-time monitoring, automation, and user-driven control of irrigation. The system
continuously measures soil moisture, temperature, and humidity, enabling dynamic threshold-based irrigation supported by a manual override option. Experimental validation confirmed that the system
operates reliably, responds accurately to changing soil conditions, and prevents unnecessary irrigation by activating the water pump only when required. Unlike existing solutions, the proposed system
provides dual operating modes, interactive threshold adjustment, and intuitive real-time visualization through LabVIEW, making it both scalable and cost-effective for small- to medium-scale farming
applications. This work contributes to sustainable agricultural practices by combining affordability, adaptability, and improved water-use efficiency.
An Investigation of Effective Document Management Strategies for Post-Contract Period Used by Consultant Quantity Surveyors in Sri Lanka
(Faculty of Engineering, 2025-09-09) Kahandawa K.A.A.G; Wijekoon, W.M.C.L.K.; Buddhini P.H.Y.
In the construction industry, efficient document management is crucial for ensuring the successful completion of projects, compliance with regulations, and the delivery of high-quality results. The
importance of proper document management becomes even more apparent during the post-contract period, as it governs essential processes such as project handover, maintenance, and future reference.
Most studies have examined document management issues from the contractor’s perspective, leaving a gap in understanding how consultant Quantity Surveyors, who manage extensive documentation during
the post-contract period, handle these challenges. This gap is critical, as poor practices cause disputes, delays, and weak claim administration, yet little research addresses it. This research aims to explore
effective strategies for managing construction documents during the post-contract period by consultant quantity surveyors in Sri Lanka. An extensive literature review was conducted to identify existing
document management strategies and assess their effectiveness. Mixed-methodology approach was adopted in this study. Data were collected through preliminary interviews, a comprehensive
questionnaire survey, and semi-structured interviews with professionals in the construction industry. The questionnaire survey yielded 50 responses from industry professionals, which were analyzed using
the Relative Importance Index (RII) analysis. Qualitative data were obtained from preliminary interviews with five industry experts and semi-structured interviews with an additional five experts,
which were evaluated using thematic analysis. The research proposes current best practices for implementing document management systems (DMS) to support construction projects. Key aspects such
as the evaluation of existing DMSs, identification of writing strategies, strategy implementation,
challenges encountered, recommended solutions, and the effectiveness of document management
strategies and standards are highlighted. The findings reveal a strong preference for physical records,
driven by concerns over digital durability, security, and familiarity. The study identified for integrate
digital DMS to enhance efficiency, security, and long-term accessibility, encouraging a gradual shift
towards more sustainable, technology-driven practices in the industry.
Impact of Emotional Intelligence on Improving Labour Productivity In the Sri Lankan Construction Industry
(Faculty of Engineering, 2025-09-09) Henadeera N.S; Bandara R.P.H.S; Buddhini P.H.Y
The construction industry plays a vital role in fostering economic growth globally, with labour productivity being a critical determinant of project success and industry competitiveness. Despite
extensive research and strategic efforts, Sri Lankan construction companies continue to face significant challenges related to low labour productivity, often stemming from interpersonal, organizational, and
technological issues. Recent studies highlight the potential of emotional intelligence (EI) as a pivotal non-technical factor that enhances individual and team performance in construction settings. This
research investigates the impact of EI on labour productivity within the Sri Lankan construction sector. Employing a mixed-methods approach, data were collected through structured questionnaires from a
diverse sample of 45 workers and open-ended interviews from interviewers, including project managers and HR professionals. Quantitative analysis using correlation techniques and qualitative thematic
analysis revealed that the impact of EI positively influences communication, teamwork, conflict resolution, and motivation among workers. Furthermore,5 key strategies and practical actions were
identified as effective measures to enhance labour performance. The study underscores the importance of integrating EI development initiatives into industry practices to mitigate common productivity
barriers and promote a more cohesive, efficient, and motivated workforce. The findings contribute to the theoretical understanding of non-technical skills in construction productivity and propose practical
frameworks for industry stakeholders to implement EI-enhanced management practices, ultimately leading to higher efficiency, safety, and project success in Sri Lanka’s evolving construction landscape.
Entrepreneurial Orientation on Talent Acquisition and Retention in Construction SMEs
(Faculty of Engineering, 2025-09-09) De Silva, M; De Silva, P
This study investigates how Entrepreneurial Orientation (EO) influences talent acquisition and retention strategies in Small and Medium Enterprises (SME). Construction SMEs often face limitations in
attracting and retaining skilled employees. Therefore, this study examines the role of EO dimensions (innovativeness, autonomy, and proactiveness) in offering a strategic approach to address these
challenges and enhance HR practices. The author adopted a mixed-method research approach for this study, collecting data through semi-structured interviews with SME managerial-level professionals and
administering a questionnaire survey among professionals in the construction sector. The data were analysed using correlation techniques and thematic analysis to identify the strategic alignment between
EO practices and talent management efforts. The findings revealed that internships and employee referrals are the most used and effective talent acquisition strategies. In terms of talent retention
approaches, performance-based incentives and career development programs were identified as dominant approaches. Moreover, the study found that the EO dimensions of autonomy and proactiveness
significantly impact the adoption and success of these talent retention and acquisition strategies. The results offer a framework for construction SMEs to improve talent-related outcomes by integrating EO
into their HR planning.
