[2026-04-20] WA startup Renewable Metals secures $12M CEFC-led funding to scale its zero-black-mass alkali battery recycling technology.

Expanding Australia’s Hazardous Waste Management Landscape

The transition of Perth-based battery recycling startup Renewable Metals from a Western Australian prototype developer to a commercially funded technology firm represents a significant shift in Australia’s hazardous waste management landscape. By securing 12 million dollars in a Series A funding round led by the Australian Government’s Clean Energy Finance Corporation, the company is poised to scale its proprietary alkali-based hydrometallurgical recycling process. This technology addresses one of the most critical structural challenges of the transition to renewable energy: the safe, efficient, and low-emission recovery of critical battery minerals without generating substantial secondary waste streams.

For Australian environmental consultants, property developers, infrastructure lawyers, and local government planners, this commercial scaling is highly relevant. As lithium-ion batteries proliferate across utility-scale energy storage systems, residential batteries, and electric vehicle fleets, the volume of end-of-life battery waste is projected to grow exponentially. Traditional recovery processes are constrained by high capital costs, severe transport risks, and toxic byproducts, which historically transferred significant liability to waste generators and landowners. The introduction of a scalable, domestic, low-impact recycling pathway offers a practical mechanism to mitigate these long-term environmental liabilities.

This development is particularly timely given the shifting regulatory landscape governing hazardous waste disposal and dangerous goods management in Australia. The historical practice of stockpiling spent battery packs or exporting them to offshore facilities faces intense regulatory scrutiny and rising legal risks. By establishing highly efficient, domestic processing capabilities, this technology provides industrial operators and site developers with a clear pathway to secure stringent waste-tracking compliance, protect themselves from chain-of-custody failures, and support circular economy goals during large-scale site decommissionings, asset retirements, and commercial lease exits.

Technical Breakthroughs in Alkali Battery Recycling

Renewable Metals has developed a next-generation alkali-based hydrometallurgical recycling process that recovers more than 95 per cent of critical minerals, including lithium, nickel, cobalt, copper, and manganese, directly from spent batteries. Unlike traditional acid-based hydrometallurgical recycling, which relies on strong mineral acids and generates massive volumes of sodium sulphate as a problematic secondary waste stream, this alkali-based method operates under chemical conditions that eliminate this secondary disposal liability. Conventional recycling processes also require the intermediate production of highly hazardous black mass, a volatile, fine powder consisting of crushed battery anodes and cathodes that presents severe dust-inhalation and spontaneous-combustion risks during handling and transit. The alkali process bypasses black mass production entirely, greatly improving workplace safety and environmental containment.

The technical mechanics of the alkali hydrometallurgical method allow for the simultaneous processing of multiple battery chemistries, such as lithium iron phosphate and nickel manganese cobalt, within a single feed. This eliminates the need for highly complex, manual, and hazardous pre-sorting or dismantling of battery packs before processing, which has historically been a primary economic and safety bottleneck in battery recycling. The 12 million dollar Series A funding round, spearheaded by the Clean Energy Finance Corporation alongside private venture capital, will be utilised to expand the company’s existing prototype facility in Kewdale, Western Australia. This Western Australian plant is scaling to process 2,000 tonnes per annum under continuous operational conditions, providing a critical testing ground for commercial-scale throughput.

Furthermore, a key component of the commercial expansion funded by this investment is the detailed engineering design for a larger, commercial-scale facility planned for New South Wales. The modular nature of the Renewable Metals technology means that processing units can be deployed close to major feedstock sources, such as metropolitan waste hubs or regional mining operations. This modularity reduces the necessity for long-distance transport of highly volatile, damaged, or end-of-life batteries, which are classified as Class 9 Dangerous Goods under the Australian Code for the Transport of Dangerous Goods by Road and Rail. By reducing transport distances, the technology directly mitigates the risks of thermal runaway events, toxic off-gassing, and environmental contamination during transit.

Australian context

The deployment of advanced battery recycling technologies in Australia aligns with several federal and state-level environmental frameworks, most notably the National Waste Policy Action Plan and the National Environment Protection (Movement of Controlled Waste between States and Territories) Measure. Currently, Australia’s geographical vastness presents a unique logistical hurdle for hazardous waste management, requiring waste generators to transport dangerous goods across vast distances to centralised disposal facilities. The capability to deploy modular, regional recycling plants directly supports state-specific waste minimisation goals and reduces the regulatory burden associated with interstate waste tracking approvals under the Controlled Waste NEPM.

Crucially, this technology arrives as the Heads of EPAs Australia and New Zealand, known as HEPA, progresses the consultation on the National Guideline for the Safe Management of End-of-life Lithium-ion Batteries. This upcoming national framework aims to harmonise state-based approaches to battery storage, collection, transport, and processing, raising the compliance requirements for lithium-ion battery processing and transport.
