Editorial: Celebrating 1 year of Frontiers in Environmental Engineering

Collectively, these six articles do more than mark an anniversary; they chart a testament to the journal's vision of fostering a collaborative, global community of environmental engineers dedicated to solving the planet's most pressing ecological challenges. They demonstrate that the future of environmental engineering lies in integrating advanced materials and biological processes, embracing systemic assessment tools, and finding value in what was once considered waste. As the journal enters its next phase, we look forward to building on this foundation, welcoming innovative research, and continuing to serve as a vital platform for sharing knowledge that empowers the environmental engineering community to protect and restore natural ecosystems for future generations.We extend our gratitude to all the contributing authors, the journal's editorial boards, and the Frontiers team for their support in making this anniversary Research Topic possible. It is our hope that these works inspire further inquiry, collaboration, and action-core tenets of Frontiers in Environmental Engineering as we move forward in our mission to advance environmental engineering for a sustainable world.
