The Chakma Research Group

About the Group

Our research group is dedicated to developing sustainable chemical and environmental engineering solutions through innovative process design and advanced material applications. The group’s core expertise lies in sonochemistry, ultrasonics, and cavitation-based hybrid processes, with applications spanning wastewater treatment, desulfurization, and the degradation of industrial pollutants. In addition, the team actively works on waste-to-energy and waste valorization technologies, integrating biochemical and thermochemical pathways to convert biomass, plastics, and municipal solid waste into biofuels, chemicals, and functional materials. With a strong interdisciplinary approach bridging fundamental science and applied engineering, the group is committed to advancing clean energy, circular economy practices, and environmental sustainability.
