Mint Innovation, an e-waste technology company, announced it has successfully produced the industry?s first batch of certified closed loop recycled copper through an industry-first collaboration with HP Inc. The milestone demonstrates Mint?s proprietary biosorption technology, which recovers high-purity copper from HP?s end-of-life printed circuit boards (PCBs) for reuse in HP PC manufacturing starting with the HP EliteBook X G2 Series laptops and HP EliteBoard G1a Next Gen AI PC. Mint Innovation?s metal recovery process uses chemistry and patented biosorption technology to recover and refine metals locally. During the initial validation phase at Mint?s Sydney facility, HP PCBs are processed to produce high-purity copper sheets; the recovered material received third-party certification from TÜV Rheinland.
The certification addresses a critical gap in the global electronics market: the lack of traceable, recycled-content verification. An independent audit by TÜV Rheinland confirmed that Mint?s recovered copper meets rigorous quality and chain-of-custody requirements across ISO 14021, EN 15343, and ISO 22095 standards. This batch-processing capability also allows Mint to offer "Recycled Metal as a Service" (RMaaS), giving manufacturers the ability to retain ownership of their strategic resources.
As part of the validation process, HP provided representative electronic waste materials and worked across its supply chain to support traceability and testing requirements. The learnings from this process help inform how recycled materials could be evaluated and integrated more consistently across future manufacturing programs, supporting broader efforts to scale circular manufacturing.
