About Roca

The meaning behind Roca

The name Roca was inspired by a rare and powerful tidal wave that surges upriver in the Amazon, reversing the flow of one of the world's greatest rivers. This natural phenomenon is both awe-inspiring and symbolic: a reminder that even the most established systems can be disrupted and transformed. 

At Roca, we also believe in reversing the flow — shifting the water treatment model from dilute and dispose to recover and reuse.

We are

At Roca, we’re a team of PhD scientists and engineers advancing electrochemical systems to solve real-world problems in water treatment and resource recovery.

We believe science shouldn’t stay in the lab. Our work transforms cutting-edge research into practical, durable tools that industrial, municipal, and agricultural partners can use.

What Drives Us

Across industries, critical resources are routinely lost to wastewater — polluting ecosystems, accelerating climate emissions, and forcing companies and communities to bear the cost.

Roca is building a platform to change that: using electrochemistry to recover valuable materials directly from contaminated water sources and return them to productive use.

Our electrochemical technology challenges outdated infrastructure and redefines waste as a resource. 

Roca represents a grounded, resilient force for change — reclaiming what’s been discarded and restoring balance to the way we manage water and material flows.

Take ammonia for example

Over 50% of the ammonia used in the U.S. is lost to wastewater each year, contributing to toxic algae blooms, drinking water contamination, and emissions of nitrous oxide, a greenhouse gas that is nearly 300x more potent than CO₂. This isn’t just harmful, it’s wasteful and represents over $4 billion in lost ammonia. 

Roca is enabling a paradigm shift to reclaim this wasted ammonia and convert it into a reusable product for agriculture and industry.

and ammonia is just the beginning.

Roca's modular platform is adaptable to a range of waterborne contaminants and dissolved resources — opening up new opportunities for nutrient recovery, decarbonization, and circular supply chains across industrial, municipal, and agricultural sectors.

Our Approach to Ammonia Recovery

  • Recover valuable resources

    Capture and convert ammonia from wastewater into nitrogen products like fertilizer, reducing pollution and waste.

  • Reduce energy consumption

    Uses up to 50% less energy than traditional methods and runs on renewable electricity for a greener footprint.

  • Built for modular deployment

    Modular, membrane-free, and low-energy—our systems are designed to integrate into real-world operations from day one.
