Faculty Biography

Prof. Benjamin Afotey is an Associate Professor in the Department of Chemical Engineering at the Kwame Nkrumah University of Science and Technology (KNUST), Ghana. As a distinguished researcher, he is deeply focused on developing technologies and methodologies relevant to addressing societal challenges, but also driving sustainable environment.His research interest include pollution control technologies; emissions measurements and modelling; biofuel and biogas production technologies; energy systems and sustainable energy technologies; and water & wastewater treatment technologies. One of his most recent research work involved development of IoT monitor for measuring regional air pollutants (NO2, CO, PM10, PM2.5) and greenhouse gases (CO2, CH4). Currently, he leads a collaborative research project at KNUST with KNMI and TU Delft, Netherlands. The team has established an Air Quality Lab at the department of Chemical Engineering, KNUST and are measuring ground-level NO2 using Palms Diffusion Tubes.He teaches undergraduate and postgraduate courses at the Department of Chemical Engineering. These include Chemical Process Design and economics at the undergraduate level, and Environmental Engineering and Fuel & Energy Technology at the postgraduate level.Prof. Afotey actively contributes to the academic community by reviewing articles for journals such as the Journal of Environmental Chemical Engineering, the Journal of Scientific African, and the Journal of Ghana Institution of Engineering, among others.
