持続可能な栄養回収と農業のためのポリマー複合材料：機能的改質と経済的便益

This review hypothesizes that polymer composites, due to their unique adsorption capacity and chemical tunability, can provide a cost-effective, efficient solution for recovering nutrients from wastewater, thereby addressing the urgent global challenge of nutrient pollution while producing potential composites for agriculture. Confirming or rejecting this hypothesis is critical, given the escalating economic and environmental costs of nutrient-induced ecosystem imbalances which amount to billions annually in water treatment, agricultural losses, and biodiversity decline worldwide. This review achieves its breakthrough by synthesizing insights from academic papers, patents, and industry reports, uncovering interdisciplinary links between polymer chemistry, environmental engineering, and agricultural science that enable novel modifications to polymer composites. The growing market for next-generation adsorbents and fertilizers, driven by stricter nutrient discharge regulations and demand for sustainable inputs, presents profit-driven business opportunities. Future research should focus on enhancing composite selectivity and regeneration, scaling production, and evaluating environmental impacts, while overcoming challenges like economic competitiveness, regulatory approval, and wastewater variability.
