ITN-BUET organized a dissemination event on Saturday, 26 July 2025, showcasing its two pioneer research projects to explore the utilization of industrial by-products, such as medical waste incineration ash, sewage sludge ash, and coal fly ash, for compressed stabilized earth blocks (CSEB) and production of sustainable concrete using geopolymer artificial coarse aggregates. The event brought together researchers, academics, and professionals from the relevant sectors for a day of knowledge exchange and discussion.
At the dissemination event, Mir Tanvir Al Biruni, Research Fellow at ITN-BUET, shared insights from his research on “Valorization of Medical Waste Incineration Fly Ash in Compressed Stabilized Earth Blocks.” He noted that his research promotes the sustainable reuse of hazardous medical waste into a durable, low-cost, and eco-friendly building material. This approach offers a viable alternative to conventional materials while reducing dependency on cement. His work also emphasizes the conservation of fertile topsoil, reduced landfill use, and support for circular economic practices in the construction sector.
Mr. Md. Rafiqul Islam, another Research Fellow at ITN-BUET, presented findings from his research titled “Performance of Concrete Prepared with Geopolymer Aggregate from Sewage Sludge Ash and Incinerated Medical Ash.” He mentioned that the research had the potential of reducing reliance on conventional brick aggregates by producing high-strength, fire-resistant concrete using geopolymer aggregates with lower carbon emissions.
Prof. Dr. Tanvir Ahmed, Principal Investigator of both the research, commended the dedication and hard work of the two Research Fellows. He noted that one of the studies has already been published in a reputed journal, while the other is currently under review, underscoring the quality and relevance of their contributions. Participants appreciated the research initiatives, shared insights, and provided valuable directives. Prof. Dr. Md. Abdul Jalil, Dean, Faculty of Civil Engineering, BUET praised the remarkable achievements of the two researchers in advancing scientific knowledge and highlighted the crucial role of high-quality research in driving innovation, informing policymaking, and fostering intellectual progress.
Prof. Dr. Rowshan Mamtaz, Director of ITN-BUET, expressed that both the research falls under ITN-BUET’s broad portfolio of research initiatives spanning sanitation, solid waste management, faecal sludge management, and Citywide Inclusive Sanitation (CWIS). Dr. Mamtaz underscored the importance of effective dissemination of research findings to industry stakeholders to ensure innovations reach the field. She encouraged researchers, particularly young professionals, to foster a strong culture of research and innovation in addressing the growing challenges of solid waste and environmental management.
