Mint Innovation, HP Close the Loop on Recycled Copper for PC Manufacturing

New Zealand-based Mint Innovation said it has produced what it describes as the first certified batch of closed-loop recycled copper recovered from end-of-life electronics and returned directly to new computer manufacturing through a partnership with HP Inc.. The companies said the material will be used in select HP devices, marking a milestone in traceable metals recovery for the electronics sector.

The copper was extracted from HP-identified printed circuit boards during a validation phase at Mint’s Sydney facility. According to the companies, the recovered metal was refined into high-purity copper sheets and independently certified by TÜV Rheinland under internationally recognized chain-of-custody and recycled-content standards.

Global e-waste volumes continue to climb. Data from United Nations agencies show the world generated roughly 62 million metric tons of electronic waste in 2022, with projections reaching 82 million tons by 2030. Less than one-quarter is formally recycled. Much of today’s recovery relies on smelting, a high-temperature process that can be energy-intensive and may not preserve full material traceability.

Mint’s approach uses a combination of hydrometallurgy and proprietary biosorption technology to selectively bind and recover metals from shredded circuit boards. The company says the process operates at lower temperatures than conventional smelting and allows batch-level tracking of recovered material from waste input through to finished metal output. Analysts note that traceability is becoming increasingly important as electronics brands face regulatory and investor pressure to substantiate recycled content claims.

According to reports, the certification covered compliance with ISO 14021, EN 15343 and ISO 22095 standards, which address environmental labeling, plastics traceability and chain-of-custody verification. Industry observers say third-party validation is critical for manufacturers seeking to integrate recycled materials into high-specification components without compromising performance.

HP said it provided representative end-of-life materials and worked across its supply chain to support traceability and performance testing. Company executives described the collaboration as part of broader efforts to scale circular manufacturing and increase the proportion of recycled materials in new products. The recovered copper is slated for use beginning with selected commercial PC lines, including models in the EliteBook and EliteBoard portfolios.

Mint is also positioning the model as “recycled metal as a service,” allowing manufacturers to retain ownership of strategic materials recovered from their own waste streams. Industry groups argue that localized processing could reduce reliance on overseas smelting capacity and mitigate supply risks tied to copper and other critical inputs.

Following the Sydney pilot, Mint is building its first U.S. commercial facility in Longview, Texas, with operations targeted for 2027. The site is expected to serve North American customers seeking domestic sources of recycled critical materials, aligning with policy incentives aimed at strengthening local supply chains.

Analysts caution that scaling advanced recycling technologies will depend on consistent feedstock supply, competitive operating costs and integration into established refining networks. Still, the collaboration signals growing momentum for closed-loop material systems in the electronics industry.
