SolPhyX is a breakthrough, nature-inspired technology that redefines how we tackle nitrate pollution. Mimicking the natural process of phytoextraction in plants, but at dramatically accelerated speeds, we use sunlight to rapidly remove nitrate from water and soil. In our first lab trials, SolPhyX achieved a 60% nitrate reduction in water in just three hours, a performance unmatched by conventional solutions. The core of our innovation is a specially designed adsorbent material that efficiently filters out nitrate from passing through water. Unlike current remediation methods that rely on costly, centralized facilities or labor-intensive practices for farmers, SolPhyX is local, fast, and scalable. This makes it accessible both for communities dealing with water contamination and for farmers seeking practical, affordable ways to protect their land and crops. Our vision is to empower communities and industries with a solution that is not only effective, but also simple to implement where it’s needed most. With SolPhyX, we transform nitrate pollution from a persistent problem into an opportunity for environmental innovation.

The rising levels of nitrate (NO₃⁻) in groundwater are a critical part of the nitrogen crisis, threatening ecosystems, drinking water, and long-term soil health. Excessive fertilizer use by farmers causes nitrate to leach into water, disrupting biodiversity and contaminating essential resources. Current solutions are slow, expensive, or impractical: farmers rely on catch crops that take months to grow, or, in extreme cases, costly soil washing. In water systems, treatment requires large, centralized facilities. SolPhyX offers a fast, local, and sustainable alternative. After cash crops are harvested, our sunlight-powered technology removes nitrate from soil or water in hours. Using an organic adsorbent material, we not only capture nitrate efficiently but can also redistribute it to regions where it is needed, closing the nutrient loop. SolPhyX can even be safely implemented in sensitive Natura 2000 areas, restoring ecological balance without disrupting habitats. By combining speed, accessibility, and circularity, SolPhyX tackles the nitrate crisis at its source. Our approach empowers farmers, protects water quality, and supports ecosystem restoration, transforming nitrate pollution from a persistent threat into an opportunity for sustainable management and long-term environmental impact.
