World leading tech recovering value from e-waste
We develop domestic, low carbon and commercially scaled technology to recover critical metals from end-of-life electronics, such as printed circuit boards.
Turning circuit boards into circular resources
01
Lower impact
Our hydrometallurgical process uses ambient temperatures and no high heat burning to produce less carbon emissions compared to traditional smelting and mining methods.
02
Locally processed
Small, city scale facilities plug into existing urban infrastructure to process e-waste domestically, reducing the need to export waste offshore where value is lost.
03
Closed-loop supply
Local small batch processing means we can return individual traceable batches of metal back to the same supply chain.
04
Third-party certified
Independently verified copper recovery process meets international recycled-content and chain-of-custody standards.
Combining naturally occuring biomass and smart chemistry
Material is prepared for processing
Printed circuit boards are milled into a fine sand to increase surface area. An initial process takes place to dissolve and recover base metals.
Copper is extracted
Using a conventional electrochemistry process, we recover large sheets of high purity copper from the solution.
Gold is extracted
To the remaining mixture, we add Mint's proprietary naturally occurring biomass which binds to gold particles like a sponge. The material recovered is then further refined to produce commodity grade gold.
Metals can be returned to domestic supply chains
These metals can be used to manufacture new technology. Once they reach end of life again, circuit boards inside can be returned to our facility and reprocessed.
Circular metals are needed for growing economies
Growing demand for critical metals
Demand for critical metals like copper continues to grow as new technologies develop and natural resources deplete, widening the supply gap.
Export and landfilling of e-waste
Exporting or landfilling e-waste means the metal value within is lost and becomes difficult to recoverable.
Carbon intensive existing processes
Existing methods of sourcing metals such as mining and smelting produce high amounts of carbon emissions.
