The increasing presence of pharmaceutical residues in global water bodies represents a significant, yet often overlooked, environmental challenge. These emerging contaminants can reduce the effectiveness of medications and, more critically, contribute to the growing crisis of antimicrobial resistance. In response to this pressing issue, a research project at the University of Energy and Natural Resources (UENR) in Ghana is pioneering a sustainable and innovative solution.

Led by Dr. Selina Ama Saah, the team is developing a highly efficient material: biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More nanocomposites. The process involves using readily available agricultural waste, specifically discarded coconut husks, which are converted into porous, carbon-rich biochar. This biochar is then engineered with zinc oxide nanoparticles to significantly enhance its absorptive capabilities. The result is a “supercharged” material capable of effectively capturing and removing pharmaceutical residues from contaminated water.

This research aligns with a multi-level strategy to address water pollution, a concern highlighted by experts who attended a recent project workshop. Beyond the technological innovation, effective solutions require public education on proper drug disposal and robust partnerships among government, NGOs, and the private sector. The UENR team is now exploring the integration of this nanocomposite into a membrane filtration system, which could provide a scalable and transformative technology for producing safe water in areas where contamination is a significant threat. This research not only tackles a critical health and environmental issue but also demonstrates the potential of harnessing sustainable materials for advanced remediation technologies.
