Mint Innovation
Developing biometallurgical processes that uses microbes to capture value from metal waste streams while mitigating environmental harm
About Mint Innovation
Mint.bio operates at the intersection of biotechnology and sustainability, focusing on transforming electronic waste (e-waste) into valuable green metals. The company serves industries reliant on critical materials, particularly the semiconductor sector, which is essential for modern electronics. By leveraging advanced biorefinery technology, Mint.bio aims to create a circular economy within the United States, reducing dependency on geographically concentrated supply chains and mitigating risks associated with material shortages.
Mint.bio's business model revolves around the collection and processing of e-waste, which is then converted into pure metals such as copper and precious metals through innovative methods like biosorption and electrochemical processes. These recovered materials are then reintroduced into the local economy, supporting the production of new electronic components and devices. The company generates revenue by selling these high-purity metals back to manufacturers and other stakeholders in the supply chain.
Mint.bio's market includes electronics manufacturers, semiconductor companies, and other industries that require a stable supply of critical materials. The company also emphasizes sustainability and environmental responsibility, aiming to reduce landfill waste and promote a greener economy.
