This review presents a comprehensive assessment of recent advancements in nature-based solutions (NbS) for the removal of ECs from wastewater. It highlights the efficacy, mechanisms, and limitations of various systems such as constructed wetlands (CWs), bio-electrochemical systems, biochar-based filters, algae-based systems, and hybrid approaches.

Beyond pollutant removal, these systems offer co-benefits of nutrient recovery, energy generation, microbial enrichment, and reduced operational costs, positioning them as multifunctional solutions for wastewater management. Critical challenges remain, including variability in performance, proliferation of antibiotic resistance genes, and limited scalability under real-world conditions. Future research should focus on hybrid eco-engineered designs, real-time monitoring tools, and standardized evaluation protocols to enable robust field-scale applications.
