Congratulations to Qudus Rafiu, Valerie Ho, and Damilola Daramola, PhD on their outstanding contributions at the 2025 AIChE Annual Meeting in Boston, MA which spanned from Nov 2-6. Qudus delivered two oral presentations, Valerie presented a poster, and Dr. Damilola gave an invited talk, highlighting the lab’s leadership in electrochemical technologies for sustainable resource recovery.
Techno-Economic Analyses of CO2 Mineralization Using Produced Water from the Appalachian Basin
Qudus presented a techno-economic assessment of a CO2 mineralization process that utilizes produced water from the Appalachian Basin. The work explores an integrated approach to carbon capture, industrial wastewater treatment, and the production of calcium carbonate as a value-added construction material. Using techno-economic analysis (TEA), the study evaluated capital costs, operating expenses, and overall financial feasibility at industrial scale, supported by sensitivity analyses to identify key cost and performance drivers.
Critical Material Recovery from Non-Traditional Water Sources: A Strategic Assessment for Clean Energy Supply Chain Resilience
In this presentation, Qudus evaluated the potential of non-traditional water sources (NTWS) as alternative resources to conventional mining for critical materials. The work assessed material abundance across NTWS and examined their capacity to help offset global demand, supporting clean energy deployment and supply chain resilience.
Raman Analyses of Electrochemically-Driven Phosphate Speciation
Valerie presented her work on in situ Raman spectroscopic analysis of phosphate speciation during electrochemical processes. Her presentation highlighted advances in analytical characterization techniques for nutrient recovery, demonstrating how Raman spectroscopy can provide real-time insight into phosphate transformations. This work contributes to improved understanding and optimization of electrochemically driven phosphorus recovery systems.
Electrochemically Mediated Phosphorus Recovery from Wastewater: On Electrode Stability and Electrolyte Composition Effects
Dr. Damilola presented an invited talk on electrochemical phosphorus recovery from wastewater, highlighting its potential to address challenges across food, energy, water, and environmental systems. The presentation focused on the effects of electrode stability and electrolyte composition on reactor performance, showing how wastewater chemistry can protect electrode materials and how cation concentration strongly influences phosphate recovery efficiency.
A big congratulations to Qudus Rafiu and Valerie Ho for representing the lab with impactful presentations at AIChE 2025, and to Dr. Damilola Daramola, our Principal Investigator, for delivering an insightful invited talk. Their work reflects the lab’s commitment to rigorous, innovative research at the intersection of energy, water, and sustainability. We’re proud of the ideas shared and excited to see how these efforts continue to shape the field.ies ahead!
