pH7 Technologies Raises $32M Series B to Scale Critical Mineral Extraction From Waste Streams

Clean energy gets all the headlines. Extraction gets the side eye. But the math never lies, you don’t power the future without pulling more out of the ground or getting a whole lot smarter about what we already threw away. pH7 Technologies Inc. decided to lean into the second option and make it look like the obvious one.

Vancouver’s own pH7 Technologies Inc., founded by Mohammad Doostmohammadi, just locked in an oversubscribed $32M Series B, and it didn’t come from tourists. Asahi Kasei and the Circular Innovation Fund stepped up alongside Fine Structure Ventures, with BHP Ventures staying in the mix and familiar names like TDK Ventures, Pangaea Ventures, BASF Venture Capital, and Rhapsody Venture Partners doubling down. That’s not a cap table, that’s a room full of people who’ve seen enough to know when something’s real.

Now let’s talk about what they’re actually doing, because this isn’t another “nice deck, big vision” situation. pH7 Technologies Inc. built a closed loop organo electrochemical process that pulls critical metals like platinum group metals and copper out of places most systems gave up on. End of life materials. Mine waste. The leftovers. The stuff everyone else priced as someone else’s problem. Turns out, with the right chemistry, waste starts looking a lot like inventory.

Mohammad Doostmohammadi didn’t arrive at this by accident. 15 years deep in extraction, processing, wastewater, the unglamorous side of the metals business. The kind of experience that teaches you where the bodies are buried, and more importantly, how to dig them up without making a bigger mess. That shows up in the product. Lower energy. Less waste. Built to plug into existing operations instead of demanding a full teardown. Translation: adoption gets a lot easier when you’re not asking operators to bet the whole plant.

The money here tells a second story. The round was oversubscribed. That word gets thrown around, but in this case it signals something simple. Demand for critical minerals isn’t slowing down, and the old ways of getting them are hitting walls. Environmental, economic, political. Pick your flavor. Investors aren’t just funding a company, they’re hedging against a broken supply chain.

And there’s a lesson sitting right under the surface for anyone building in hard tech or climate. pH7 Technologies Inc. didn’t chase hype cycles. They went straight at a painful, expensive problem and built something that fits into the real world, not just a pitch deck version of it. Then they brought in strategic capital that actually understands the battlefield.

Because in this game, it’s not about who talks the loudest. It’s about who can pull value out of what everyone else ignored, and do it at scale without blowing up the system they’re trying to fix.
