The pervasive use of antibiotics poses a significant environmental challenge by promoting the spread of antibiotic-resistant genes, threatening both ecosystems and human health. Addressing this issue, a recent study published in ACS ES&T Engineering examines the potential of biochar—a sustainable, carbon-rich material—in removing antibiotics from water.

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, recognized for its affordability and environmental friendliness, offers a promising solution for antibiotic remediation. Its porous nature and carbon content make it an excellent medium for adsorbing pollutants. The study delves into various mechanisms through which biochar removes antibiotics, including electrostatic and hydrogen bonding interactions, hydrophobic reactions, π–π electron donor-acceptor interactions, and pore diffusion.

Moreover, biochar serves as a microbial habitat, carrier, and electron mediator, further enhancing its ability to eliminate antibiotics from water. These biotic and abiotic interactions collectively facilitate the effective removal of different classes of antibiotics, proving biochar’s versatility as a remedial tool.

The review also assesses how different factors influence the efficiency of antibiotic removal. It discusses the optimization of biochar properties through engineering approaches, tailored to specific environmental applications. By highlighting both the achievements and challenges in the field, the study outlines a path forward for integrating biochar into strategies to treat antibiotic-contaminated waters.

This comprehensive evaluation underscores the need for continued research and development in biochar technology, aiming to harness its full potential in safeguarding environmental and public health from antibiotic pollution.
