Graphite goes green: waste-to-battery race heats up globally

By mid-2026, breakthrough technologies have emerged that transform low-value waste streams into battery-grade graphite, signaling a major shift toward sustainable supply chains. CarbonScape, a New Zealand firm backed by Chinese battery giant CATL's 20% stake, has pioneered a proprietary process converting forestry residues into high-purity, bio-based graphite suitable for lithium-ion battery anodes. This carbon-negative approach not only addresses the environmental footprint of traditional oil-based graphite but also exemplifies a circular economy model by turning forestry by-products into valuable industrial materials, potentially reducing supply chain vulnerabilities and costs for EV manufacturers.

Simultaneously, researchers at Penn State University have developed an innovative method to convert PET plastic waste into synthetic graphite with a more ordered crystal structure than natural graphite, using minimal graphene oxide and controlled thermal treatment without metal catalysts. This early-stage technology tackles two pressing challenges—plastic pollution and the growing demand for battery-grade graphite—offering a promising sustainable alternative that aims to scale industrially and prove its efficacy in battery cells, potentially providing a cleaner raw material source for the expanding EV market.

By mid-2026, Chinese battery giant CATL strategically acquired a 20% stake in New Zealand’s CarbonScape, a company pioneering the production of high-purity biographite from sustainably sourced forestry byproducts. This partnership leverages CATL’s industrial expertise to accelerate the commercialization of bio-based graphite by the decade’s end, signaling a major push to scale sustainable graphite production while supporting regional supply chains and regulatory sustainability goals. CATL’s backing not only validates CarbonScape’s circular economy approach but also aims to reduce supply chain vulnerabilities and battery costs by turning waste streams into valuable battery materials at industrial scale.

Simultaneously, Renascor’s inauguration of a purified spherical graphite demonstration facility in South Australia marks a critical milestone in sustainable battery materials production. This facility, which produces battery-grade graphite exceeding 99.99% carbon purity using a hydrofluoric acid-free purification process, is underpinned by significant government support including a A$5 million grant and a conditionally approved A$185 million loan. Such strategic investments underscore Australia’s growing role in diversifying global battery supply chains and advancing environmentally friendly graphite production technologies.

The Kearney Graphite Project in Ontario exemplifies a financially robust advancement in North American graphite production, boasting an after-tax NPV of USD$183 million and a 67% IRR, underpinned by a 20-year mine life and capital-efficient brownfield redevelopment. Management’s commitment to resource expansion and downstream anode material production highlights a strategic push to enhance long-term value and meet growing industrial and battery market demands domestically.

Graphite One is spearheading U.S. graphite supply chain integration by advancing its Ohio Active Anode Materials facility through detailed engineering and regulatory milestones, including the Ohio EPA’s acceptance of its air permit application in July 2026. Targeting an initial 10,000 tonnes of synthetic graphite production by late 2027 and scaling to 25,000 tonnes by 2028, the project’s phased approach leverages feedstock from the Graphite Creek deposit in Alaska, aligning production timelines to systematically reduce execution risk and bolster domestic battery material security.

CEO Anthony Huston underscores Graphite One’s developments as a 'defined, de-risked path' toward a fully integrated U.S. graphite supply chain, a vision reinforced by federal support through initiatives like the FAST-41 permitting process and Defense Production Act programs. This alignment with the July 2026 White House Executive Order reflects a national strategy to diminish foreign dependency and accelerate domestic supplier qualification, positioning Graphite One’s Ohio and Alaska projects as critical pillars in America’s battery independence and critical minerals security.

Beyond production milestones, Graphite One’s Ohio facility is poised to stimulate regional economic revitalization by creating 30-40 permanent manufacturing and technical jobs initially, with plans to add over 100 more as the project expands. This job creation complements the broader strategic imperative to establish a resilient, domestic graphite supply chain that supports the projected eleven-fold increase in North American graphite demand by 2030, marrying economic development with supply chain sovereignty.

The acceptance of Graphite One's air permit application by the Ohio EPA in July 2026 marks a pivotal regulatory milestone that accelerates the establishment of a domestic battery-grade graphite supply chain. This development is critical as S&P Global Mobility forecasts an eleven-fold surge in North American battery graphite demand—from 56,000 tonnes in 2023 to over 620,000 tonnes by 2030—underscoring the urgency for robust local production capacity to meet burgeoning market needs.

Graphite One’s phased approach, initiating synthetic Active Anode Materials production in Ohio by late 2027 before commencing natural graphite mining in Alaska in 2029, strategically mitigates execution risks while positioning the company to capitalize on soaring North American demand. This integrated mine-to-anode supply chain aims to drastically reduce U.S. reliance on imported graphite—particularly from China—thereby enhancing critical mineral security and fortifying supply chain resilience against geopolitical uncertainties.

The July 2026 Executive Order issued by President Trump reinforces the federal government’s commitment to domestic critical minerals supply chains by promoting local sourcing, reducing foreign dependence, and expediting new supplier qualification. Graphite One’s U.S.-based graphite platform aligns seamlessly with these national priorities, benefiting from supportive policies such as the FAST-41 permitting process and Defense Production Act programs that advance U.S. defense, energy security, and advanced manufacturing objectives.

By 2031, the global graphite market is set to surge to USD 10.10 billion from USD 6.30 billion in 2026, propelled by a near 10% CAGR fueled primarily by the rapid expansion of lithium-ion battery gigafactories and electric-arc-furnace steel production. While Asia-Pacific maintains its dominance with China leading production and key contributions from Japan, South Korea, and India across battery, semiconductor, and steel sectors, North America is strategically ramping up its graphite mining and anode manufacturing capabilities. This North American growth, supported by government initiatives and increasing EV production, faces hurdles in raw material availability but signals a significant shift toward regional supply chain resilience.

Australia is carving out a pivotal leadership role in the global graphite supply chain through advancements in vertically integrated battery anode material production. Renascor Resources’ opening of a purified spherical graphite demonstration facility in South Australia, backed by a A$5 million government grant and a conditionally approved A$185 million loan, exemplifies this strategic positioning. Notably, the facility’s innovative hydrofluoric acid (HF)-free purification process, achieving battery-grade graphite purity exceeding 99.99%, not only addresses cost and regulatory challenges but also aligns with evolving demands for more sustainable lithium-ion battery materials.
