Can Desalination Solve Water Scarcity? | Sachin Nair, CEO @ Hydron

Waste is not a side issue in the climate conversation. It sits at the center of how we produce, consume, and ultimately account for the resources we extract from the planet. On The Grove, Earth Onward's interview series with founders and operators building climate technology, waste and recycling comes up again and again because the people solving these problems are rethinking systems, not just improving them.
The throughline across these episodes is circularity. Whether the conversation turns to what happens after a product is used, how industrial byproducts get redirected, or how resource recovery can become a business model rather than a cost, guests on The Grove share a common belief that waste is largely a design failure waiting to be corrected.
Listeners and readers who explore this vertical will find conversations grounded in real business challenges: how to build infrastructure at scale, how to change behavior without waiting for regulation, and how capital flows into sectors that have historically been overlooked. These are not theoretical discussions. They come from people who are running companies, raising money, and working through the hard problems that make circularity difficult in practice.
If you arrived here through search, you are likely already asking the right questions. Browse the episodes below to hear directly from the operators building the next generation of waste and recycling solutions.
