Renewable Metals Closes Oversubscribed $12M Series A as Kewdale Alkali Recycling Plant Prepares for Mid-2026 Launch

Introduction

A Perth-based battery recycling startup has secured A$12 million in Series A funding to advance what its backers are calling a solution to one of the industry's most stubborn technical problems: how to process multiple lithium-ion battery chemistries together, at high recovery rates, without generating the problematic waste streams that have hampered conventional approaches. Renewable Metals, founded in 2020 by a team of West Australian metallurgists, closed the round in April 2026 after investor demand pushed the raise well past its original A$8 million target. Total funding since inception now exceeds A$38 million, including support from Australian and UK government programs.

The timing matters for reasons beyond the company itself. Battery recycling is among the fastest-growing segments of the critical minerals supply chain, and the Western world's capacity to process end-of-life batteries at scale remains heavily reliant on Chinese infrastructure. China currently controls an estimated 70 to 78 percent of global battery recycling pre-treatment capacity and approximately 89 percent of black mass refining capacity. Against that backdrop, a modular, lower-cost alkali process that can operate viably in Western cost environments is attracting serious institutional attention.

Building on my earlier analysis of the oversubscribed Australian Series A validating battery recycling chemistry breakthroughs, covered in my June 2026 piece on the Western world's critical mineral processing push, the Renewable Metals raise offers a closer look at both the specific technical claims and the broader structural opportunity they represent. The company's Kewdale prototype plant in Western Australia is scheduled to begin continuous 24/7 operations from mid-2026, and a Front End Engineering and Design study is underway for a first commercial facility in the Hunter region of New South Wales.

The Funding Round: Who Invested and Why

The Series A was led by Virescent Ventures, the climate technology investment arm of Australia's Clean Energy Finance Corporation (CEFC). Joining the round were Neglected Climate Opportunities, new investor Climate Tech Partners, and existing shareholders European Metal Recycling (EMR) and Investible. Hamilton Locke advised Renewable Metals on the raise.

Virescent Ventures partner Blair Pritchard identified a specific technical claim as the central investment thesis: the ability to process NMC and LFP chemistries together on a single line. "Processing NMC and LFP together has been the unsolved problem in battery recycling," Pritchard said. "Conventional approaches require separate lines for each chemistry, duplicating capital and operating costs and limiting flexibility as the market evolves. Renewable Metals has solved for that. Their single-line process handles both chemistries together, which is technically non-trivial and commercially significant as LFP's share of the market continues to grow."

The commercial significance of that last point is hard to overstate. LFP (lithium iron phosphate) has grown from just 19 percent of the global battery market in 2020 to 55 percent in 2025, according to Benchmark Intelligence data, and accounted for over 90 percent of global stationary battery storage installations last year per the IEA's Global EV Outlook 2026. Any recycling business that cannot efficiently handle LFP is increasingly misaligned with the direction of the market.

Patrick Sieb, co-founder of new investor Climate Tech Partners, framed the opportunity in supply chain terms: "Australia needs to capture the value chain of battery recycling instead of simply sending products to Asia. There is finally an Australian technology and capability that makes the investment decision incredibly compelling." Sieb also noted the coming regulatory tailwind: governments in the EU, US, and Australia are expected to introduce recycled content mandates and restrict the export of battery waste, a development that would materially improve the economics of domestic recycling operations.

EMR's continued participation through the Series A reflects the strategic depth of that relationship. The UK-based company, the largest end-of-life vehicle recycler in Britain with roughly 3,000 staff and ten million tonnes of material annually returned to the supply chain, acquired a significant stake in Renewable Metals in mid-2024 and committed to building a demonstration-scale plant at its R&D complex in Duddeston, Birmingham. That facility, supported by a UK Advanced Propulsion Centre ARMD3 grant and developed in collaboration with the University of Birmingham and the Manufacturing Technology Centre, targets the same two-stage shredding and refining process to yield LME-grade nickel and copper alongside cobalt, lithium, and manganese salts.

The Technology: Why Alkali Changes the Equation

Renewable Metals' core process departs from the dominant paradigm of acid-based hydrometallurgy in ways that address multiple longstanding criticisms of battery recycling economics. The founders drew explicitly on Australia's extensive industrial history in alkali-based metallurgy, particularly nickel and cobalt refining, to develop what they describe as a world-first application of the chemistry to lithium-ion battery recycling.

The process achieves greater than 95 percent recovery rates for critical minerals at pilot scale. For lithium specifically, the company reports recovery rates up to 30 percent higher than conventional acid-based methods, a claim that has been evolving since the seed round in late 2023, when initial data indicated roughly 20 percent higher lithium recovery. The improvement reflects ongoing process refinement, though independent third-party verification of the current figures has not been publicly reported.

The absence of sodium sulphate as a byproduct is a materially important differentiator. Acid-based processes neutralise their leaching solutions with sodium hydroxide or similar bases, generating sodium sulphate as a low-value, high-volume waste stream. In the United States and across the European Union, disposal of sodium sulphate carries significant cost and regulatory complexity, and the burden is projected to intensify as recycling volumes scale. By eliminating that waste stream entirely, Renewable Metals removes a cost category that can represent a meaningful fraction of total operating expense in conventional facilities.

The single-line architecture addresses another structural cost problem: the need for separate processing infrastructure for different battery chemistries. As CEO Luan Atkinson explained, the company's approach also eliminates the intermediate black mass production step common in many competing processes, recycles its reagents and wastewater in a closed-loop configuration, and accepts batteries as received after a rapid discharge step, without requiring pre-sorting or dismantling. "Our process changes the economics of battery recycling," Atkinson said. "By delivering high recovery at low cost without large, centralised facilities, we can build plants sized for near term feedstock, and scale with the market over time."

The modular plant design is central to the commercial model. Conventional recycling facilities are typically sized for projected future feedstock volumes, requiring large upfront capital commitments that can be difficult to justify in markets where battery waste volumes are still ramping. Renewable Metals argues its modular approach allows a plant to be built for current feedstock availability and expanded as volumes grow. Third-party analysis cited by the company suggests its plants can operate at approximately 50 percent lower cost than incumbent technologies, a figure that reflects both the chemistry advantages and the reduced capital intensity of the modular configuration.

Kewdale to Hunter: The Path to Commercial Scale

The primary use of Series A proceeds is to fund continuous 24/7 operations at the Kewdale, Western Australia prototype plant from mid-2026 through to early 2028. The facility begins at 960 tonnes per annum, scaling to 2,000 tpa, which the company equates to recycling approximately 4,000 electric car batteries per year. The objective is to generate sustained, near-commercial performance data that can validate the technology at meaningful scale and directly inform the engineering of a first commercial plant.

That first commercial facility is targeted for the Hunter region of New South Wales. A FEED study is currently underway, and the Hunter Valley location is strategically significant: it positions Renewable Metals closer to the concentrated battery waste streams of Australia's most populous eastern seaboard and adjacent to existing minerals processing infrastructure and potential downstream customers.

Chairman Peter Beaven, the former BHP CFO and President of both BHP Copper and BHP Manganese, placed the company's ambitions in explicit competitive context. "Today, battery recycling is dominated by China, with Western markets reliant on exporting materials offshore for processing," Beaven said. "Renewable Metals is building a platform that can compete with leading Chinese recyclers at scale, while enabling recovery of critical minerals in Western cost environments and beyond."

Atkinson's description of the distributed network model is worth examining in detail. Rather than a hub-and-spoke model with large centralised processing facilities accepting feedstock transported from wide catchment areas, Renewable Metals envisions a network of modular plants sited close to battery waste sources. This reduces both the cost and the regulatory complexity of moving hazardous materials over long distances, a consideration that becomes more important as governments tighten the rules governing battery waste export and transport. "This avoids capital intensive overbuild while enabling a distributed network close to feedstock sources globally, reducing the cost and complexity of transporting hazardous materials," Atkinson said.

Market Context: Australia's Battery Recycling Moment

The Series A closed approximately one month after the Association for the Battery Recycling Industry published a commissioned economic analysis that quantified the opportunity in striking terms. The report, prepared by Positive Economics Advisory and presented at Parliament House in March 2026, estimated Australia's battery materials recovery sector currently contributes A$2.1 billion to the national economy, including A$760 million in direct benefits, and supports 19,450 jobs. With appropriate policy settings, those figures are projected to grow to A$6.9 billion and more than 34,600 jobs by 2050.

The volume numbers driving that projection are equally significant. End-of-life lithium-ion batteries in Australia are forecast to roughly triple from approximately 16,000 tonnes in 2024 to around 46,000 tonnes in 2030, and to exceed 600,000 tonnes annually by 2050, a more than 36-fold increase. The cumulative recoverable value of battery materials by 2050 is estimated at A$67 billion. To put the recovery challenge in perspective, only around 10 percent of Australia's lithium-ion battery waste was recycled in 2021, compared to 99 percent of lead battery waste.

David Williams-Chen, managing director of Positive Economics Advisory, described the oncoming wave of end-of-life batteries as an economic gift rather than a waste management problem: "We are looking at a 36-fold surge in used lithium batteries, that is actually a massive economic gift. In an era of low economic growth and sluggish productivity, battery recycling offers Australia a new economic lever to pull on."

The global picture reinforces the strategic stakes. China's dominance of battery recycling is not static; it is actively expanding. Benchmark Intelligence data shows China's black mass refining capacity nearly tripled between 2022 and 2025, from 895,000 tonnes to 2.5 million tonnes. A regulatory shift in August 2025 opened Chinese markets to imports of high-grade black mass, and tariff reductions at the start of 2026 further adjusted the economics. For Western battery waste, this creates a risk analogous to what has played out in rare earth processing: the path of least resistance leads to Chinese infrastructure, and dependency deepens with each tonne processed offshore. The rare earth parallels are not lost on investors and policymakers who have spent the past several years watching Western governments scramble to build alternatives to Chinese dominance in critical mineral supply chains.

Conclusion: Prototype Data Will Tell the Story

Renewable Metals has assembled a credible set of ingredients: a technically differentiated process, an experienced leadership team with deep metallurgical credentials and senior industrial management experience at the board level, a strategic industrial investor in EMR, an active institutional investor in CEFC, and a prototype plant approaching commercial-scale continuous operation. The oversubscription of the Series A, upsizing from A$8 million to A$12 million on strong investor demand, reflects genuine conviction from the investor community.

The critical next chapter is the one that will be written at Kewdale over the coming 18 months. Continuous 24/7 operation is a materially different challenge from batch-scale or intermittent pilot runs. Demonstrating that the greater than 95 percent recovery rates, the 30 percent lithium advantage, and the single-line multi-chemistry capability hold up under sustained throughput will be the evidence base that supports or complicates the FEED study for Hunter and the broader global deployment thesis.

The regulatory backdrop is moving in the company's direction. Expected recycled content mandates and battery waste export restrictions in the EU, US, and Australia would structurally improve the unit economics of domestic processing facilities regardless of technology choice, and would directly validate the distributed network model that underpins Renewable Metals' commercial strategy. China's evolving stance on black mass imports adds another variable to watch: if Chinese recyclers aggressively compete for Western battery waste feedstock, the pressure on Western governments to act on export restrictions will intensify.

For the broader critical minerals supply chain, Renewable Metals represents a different kind of domestication challenge than the mine-to-magnet rare earth buildout that has consumed billions of dollars of Western government capital over the past three years. Battery recycling converts an existing and growing domestic waste stream into critical mineral supply without requiring new mine development, new geological discoveries, or multi-decade permitting timelines. If the Kewdale data validates what the company is claiming, the path from prototype to commercial deployment could be measured in years rather than decades, which is precisely the kind of timeline that the Western world's battery supply chain urgency demands.
