Establishing a Novel Nitrogen Cycle
Through Resource Recovery from NOx

Current approaches to addressing issues in the nitrogen cycle tend to focus on individual domains—emission sources, atmospheric conditions, water quality, and soil systems—each examined in isolation. While these domain-specific solutions have yielded appropriate responses thus far, the construction of a future-oriented nitrogen cycle that supports sustainable development demands a fundamental transformation of existing processes.

To meet this challenge, the project aims to integrate knowledge across diverse research fields—atmosphere, water, and soil—breaking down disciplinary boundaries. Through this borderless collaboration, the research team will make a comprehensive contribution to achieving a sustainable and future-ready nitrogen cycle.
