About pH7 Technologies
pH7's award-winning closed-loop technology is transforming critical metals extraction, supporting the transition to clean and renewable energy (e.g., hydrogen). This innovative process increases the supply of critical metals—such as copper, platinum, palladium, rhodium, and radium—through an environmentally and economically sustainable approach rooted in the circular economy.
The process uses organic, inorganic, and electrochemical methods to recovers metals from primary and secondary resources, including end-of-life materials that traditional methods struggle to process. It reduces wastewater, prevents hazardous chemicals from entering the environment, and lowers CO2 emissions to near zero. This approach makes it possible to sustainably extract the critical metals needed for green energy solutions.
Recent Recognition & Awards: Recognized “One to Watch” at the 2024 Cleantech Export Summit by Export Development Canada (EDC)
Winner of the Environmental Sustainability Award, In 2024 Burnaby Board of Trade Business Excellence Awards
Named in the prestigious 2024 Global Cleantech 100
Selected for the SET100 list of emerging climate tech startups
Recipient of Clean50/Clean16 awards for excellence in cleantech R&D
Strategic Partnerships: We're proud to collaborate with industry leaders including BASF, Mitsubishi International, and Johnson Matthey to advance sustainable metal processing globally.
Our Technology Advantage: Proprietary process that outperforms traditional pyro and hydro metallurgy approaches
Zero toxic emissions, wastewater, or effluent
Significantly reduced energy consumption
Higher quality metal recovery
Economically viable processing of previously uneconomical materials
Our breakthrough technology is enabling the transition to renewable energy while helping partners achieve their sustainability goals in four key areas:
PGM processing Copper ore extraction E-waste recycling Green hydrogen production
