Meet the people behind the mission

We’re a team of researchers, engineers, and environmental problem-solvers with deep roots in science and a drive to make it real. We’ve seen how broken the nutrient cycle is—and we’re here to fix it.

What began with years of academic research has grown into something far more ambitious. We’ve tested our solution in the lab and the field and are now scaling it up for real-world impact.

With decades of experience in environmental engineering and wastewater treatment, we’re united by one belief: technology can turn the circular economy from a buzzword to the optimal way forward. And we’re building the tech to make it happen.
