Q&A: can recycling help companies prepare for a lithium boom?
An anticipated spike in lithium demand is causing companies to reconsider their supply chains, with the International Energy Agency estimating that lithium supply for clean energy technologies needs to increase by 90% to meet its Sustainable Development Scenario. To help meet this target, the need to establish a robust and sustainable recycling industry is more pressing than ever before.
Danielle Spalding, VP of communications & public affairs at battery recycling company Cirba Solutions, says that the rising role of AI and data centres is driving energy storage demand and challenging critical mineral supply, putting an additional squeeze on the industry.
Mining Technology speaks to Spalding about the current state of the lithium recycling industry, the need for international collaboration to diversify supply chains, and how companies in Australia and beyond can look to bolster their recycling capabilities.
Danielle Spalding (DS): The last five years have been very different to the past 25 in the world of recycling.
I think one of the biggest reasons for the shift is the focus on electrification for all. Countries are realising that to compete on a global scale, they have to be able to strengthen domestic supply chains, to do more business domestically and have stronger exports of critical minerals.
The most recent insights show that around 25% of lithium supply will come from recycled materials (what we call secondary content) by 2040. That is a quarter of all lithium supply coming from recycled content. To compare this, cobalt will have over 35% recycled content by 2040 and nickel will have a slightly smaller percentage – around 12%.
We are really at the cusp of a big change in recycling – one that has already begun. The trick at the moment is for us to consider how we can collaborate internationally to generate these additional resources.
Places like Australia and Europe are looking at how to enhance technology to domesticate critical mineral refinement. They are also now having to meet renewable energy targets, reduce emissions, as well as manage the pressures of various geopolitical issues. All of this comes into play when considering the lithium supply chain.
DS: The more control you have over the supply chain, the more stable you are. China currently has the highest refinery of any of the critical minerals. More than likely, the majority of battery materials in Australia are going to China or South Korea for refinement. The goal now should be to domesticate more of this process than is currently seen to close the loop on these critical minerals.
We are already seeing mining companies trying to diversify portfolios into recycled content options. There is no longer a focus on one particular element of the supply chain, because companies now know they have to demonstrate the ability to increase their critical minerals supply to meet increasing demand.
DS: It is a tough pivot for companies that have historically focused on traditional types of refinement, because refining a used battery is very different from refining a virgin material. While there may be some similarities in the feedstock or the input of material in used batteries, the overall process is different by chemistry.
We are seeing Europe and North America currently sharing a lot more with regards to information resources, and you see a lot more of the regulatory landscape changing. In the UK there is the battery passport – every region has its own unique approach to controlling the critical minerals sector.
Because Australia has such vast resources, spread out over huge areas, it has different needs when it comes to transportation networks and infrastructure developments when compared with places in Europe.
So, the shift to more stable battery refining processes is under way, but it is not an easy change for companies.
DS: The computing power of AI tools is only going to increase. That means you need more data powering capacity, which means you need power backups. Often that has to be battery power at this point.
We are going to need a significant increase in battery power as we see this increase in computing demands.
However, there is also an element of AI that is being used in the battery recycling process itself, where it is being used to integrate software into material recovery facilities.
There are now tools being implemented to sort and scan materials for battery content, so it doesn't go into the wrong kind of processing. We have had multiple versions of AI usage in our own organisation, whether that is through X-ray scanning or AI-learning tools to help it sort the materials coming in.
I think that you are going to see significant battery adoption from an AI computing standpoint ─ and you are going to want to see those companies add in partnerships with organisations that help recycle.
DS: This is going to sound simplistic, but I can assure you, it is not. I think the barrier is education.
A lot of consumers don't understand they can recycle their batteries and, even if they do, they often don't know where to go to recycle them.
Part of this education is establishing the infrastructure to help people recycle batteries. In somewhere like Australia where there is a lot of farmland, people may not have a convenient location to bring the batteries from their farming equipment – all of these processes take work and they take time.
It is going to continue to be a little bit higher of a cost, but we have to get up to that point so we can then help make batteries more cost effective. We want to be able to help support a reduction in consumer and business costs so that this recycling process becomes a known, viable option.
DS: We need to see those types of partnerships in greater magnitude for the future to help reach critical mineral supply goals, both in terms of what organisations have set for themselves and the goals that each individual country has set for itself.
Consumers today are demanding a more renewable product overall. Each generation that comes into the market has a higher expectation of that. Even without this environmental, social and governance element, there is also an incentive to strengthen supply chains from a national security perspective.
DS: There is a significant opportunity to expand the infrastructure necessary to safely collect, process and reuse lithium batteries at scale. We also need to close the education gap so that consumers and businesses better understand the value of lithium battery recycling and the importance of recovering those critical resources to be reused.
Equally important is addressing the economic model of the industry. The industry needs to set reasonable expectations, so we can create a thriving and diversified market for the future.

Why India's Budding EV Sector Has Opened Its Doors To China
For decades, China has driven the lion's share of oil demand growth thanks to its remarkable economic boom and large population. However, China is now losing its prominence in global oil markets due to a dramatic slowdown in its economy coupled with the country's ongoing electric vehicle revolution. Last year, nearly half of all new cars sold in China were electric vehicles, including both battery-electric and plug-in hybrid electric vehicles. Indeed, China's rapid adoption of EVs, as well as rapid growth of high-speed rail and natural gas trucks, is displacing traditional fossil fuel demand, with the International Energy Agency (IEA) predicting that China's oil demand will peak as early as 2027. Ironically, the country that is taking over China's mantle in world oil markets is also aspiring to follow in its EV footsteps: India. Unlike China, India's EV sector is still at its infancy, with electric vehicles accounting for just 2.5% of all cars sold in the country in 2024. However, India has big EV ambitions, with the Indian government having set a target for EVs to make up 30% of total passenger vehicle sales by 2030. To accomplish this, India's EV sector is forging close ties with Chinese EV manufacturers at a time when Washington has been keeping Chinese EV giants at bay. India is relying on Chinese EV tech to bridge the gap until the domestic sector is ready to compete on the global stage. Industry analysts note that without access to Chinese technologies—including batteries, drivetrain components, and EV software—India would likely face slower product rollouts, limited model variety, and higher costs during its growth phase. This marks a clear pivot from just a few years ago, when India restricted the operations of firms like BYD and banned popular Chinese apps such as TikTok and Shein after deadly clashes at the New Delhi appears to be taking a more calculated stance. In March, the government reduced tariffs on over 35 EV components, many of which are imported from China, making it easier for automakers to source critical parts. A few weeks later, India's Ministry of Heavy Industries unveiled a new EV policy slashing import duties on fully built EVs from 110% to 15%, provided manufacturers invest and set up local production. This dual-pronged approach aims to attract international players while building out domestic supply chains. Experts view these shifts as pragmatic. Leading Indian EV makers—such as Tata Motors, Ola Electric, and Mahindra & Mahindra—continue to depend on Chinese vendors for components like battery cells, power control units, and electric motors, even though assembly is carried out in India. 'The aim is to build a resilient domestic ecosystem, not to isolate it, unlike the more aggressive decoupling seen in the U.S. with China,' said Shubham Munde, senior analyst at intelligence firm Market Research Future. Yet this growing alignment between Indian and Chinese EV sectors is creating both opportunity and competition. MG Motor—a joint venture between India's JSW Group and China's state-owned automaker SAIC—has managed to double its market share over the past year, putting pressure on homegrown giants like Tata Motors. Its model, the MG Windsor, is now India's top-selling electric car, highlighting how joint ventures are gaining traction. At the same time, India's EV landscape remains deeply fragmented. According to Bernstein Research, just four legacy automakers dominate 80% of the electric mobility market, leaving over 150 EV startups struggling to establish a foothold in an increasingly competitive space. Government policy appears to be playing an outsized role in the EV trajectories of different countries. In its 2025 Electric Vehicles Outlook, Bloomberg New Energy Finance (BNEF) cut both its near-term and long-term passenger EV adoption outlook in the United States for the first time ever, citing key policy changes including rollback of national fuel-economy targets as well as the removal of supportive elements of the Inflation Reduction Act (IRA) by the Trump administration. In contrast, S&P Global Mobility has forecast strong growth for India's nascent EV sector, projecting that production of battery-electric passenger vehicles will increase by 140% year-over-year in 2025 to roughly 301,400 units. That would represent about 6% of the estimated 5.16 million passenger vehicles expected to be built in India that year. Still, the road to India's 2030 goal may be steep. According to S&P, India would need to boost EV adoption by approximately 380 basis points annually to reach 30% market share—nearly double the current growth rate of around 200 basis points per year since 2021. Compounding the challenge is the lack of a unified long-term roadmap and the pending expiration of several state-level EV incentive programs.

Lithium in Australia: the future of the ‘white gold' rush
The global lithium market is undergoing a period of flux. Following years of solid growth, prices have plummeted from their 2022 peak amid slowing demand for electric vehicles (EVs) and an oversupply from global producers. Overall, the cost of lithium hydroxide fell by around three quarters between 2023 and 2024, and has continued to fall in 2025. Australia, the world's largest producer of lithium ore (accounting for 46% of the global total in 2024), felt this decline more sharply than most, forcing several mining operations to pause amid deteriorating market conditions. However, a rebound may be on the horizon. Analysts expect a resurgence in 2025, fuelled by renewed growth in EV adoption and clean energy storage. Although lithium prices remain difficult to predict, Australian miners are once more betting big on the metal. With an abundance of active lithium mines and reserves, Australia is well placed to be at the forefront of this lithium opportunity. However, as demand grows, questions have been raised as to how this burgeoning market can remain sustainable and how waste streams can be safely managed. Strengthening domestic recycling capabilities, developing greener processing methods and building closed-loop supply chains could be key to ensuring that growth in lithium production does not come at the expense of the environment. By 2040, the International Energy Agency (IEA) expects demand for lithium to be more than 40-times current levels if the world is to meet its Paris Agreement goals. As such, despite the current market volatility, optimism about the future of lithium remains strong. In this context, Australia has positioned itself to be a leading global supplier. In 2024, the federal government extended a A$230m ($149.81m) loan to Liontown Resources, which began production at its Kathleen Valley mine last July. The mine is expected to produce around 500,000 tonnes (t) of spodumene concentrate annually. Spodumene is Australia's main source of lithium. Meanwhile, Perth-based Pilbara Minerals plans to boost lithium ore production at Pilgangoora by 50% over the next year through its P1000 project. Crucially, there has been an uptick in interest to build out not only the extraction side of the lithium supply chain but also refineries. For instance, in Western Australia, Covalent Lithium is constructing its own lithium refinery, while Albemarle is operating another refinery in the region. The motivation behind the shift in focus stems from efforts to diversify critical minerals supply chains and move away from China's continued dominance. According to the IEA, China currently accounts for 70% of global lithium refining. 'At the moment in Australia, we are doing the mining and integration aspects of lithium-ion [Li-ion] batteries really well,' says Neeraj Sharma, chemistry professor at the University of New South Wales, and founder of the Australian battery society. 'Our grid is years ahead when it comes to battery storage. It is the middle part of the supply chain that we need to grow – the processing and cell manufacturing aspects.' Similarly, Serkan Saydam, chair of mining engineering at UNSW Sydney, believes the main gap in Australia's lithium supply chain lies in the processing and refining element. 'While Australia excels in lithium extraction, it currently lacks sufficient domestic processing and refining capacity, leading to reliance on overseas facilities,' says Saydam. Indeed, in 2022–23 Australia exported 98% of its spodumene concentrate for processing. Both Sharma and Saydam identify developing lithium processing capability as necessary not only for Australia's national security and economic growth but also for sustainable industry development. Saydam says developing low-emission processing infrastructure is essential 'not only for economic gain but also for minimising environmental impacts through tighter regulatory oversight'. Building out this part of the supply chain could also, Sharma believes, help establish a more robust battery recycling industry in Australia. 'If we know what is going into the batteries from a processing perspective, it will better equip us to know how to recycle them at the end of life,' he tells Mining Technology. 'We are seeing a lot of interest from the mining and start-up sectors to move towards this, but right now, without the right electrode processing or refinement in-country, it is harder to create the recycling processes needed in-country.' According to the Commonwealth Scientific and Industrial Research Organisation, only around 10% of Li-ion battery waste is currently recycled in Australia. However, Sharma predicts that as large-scale battery demand grows, so too will the recycling rates. 'I think recycling rates for things like EV batteries will be close to 100%,' he says. 'Just by the nature of the fact that these batteries are large, people won't want to have them hanging around.' The difficulty, he says, lies in scalability and the fact that battery chemistry is still evolving. 'Currently there are not enough Li-ion batteries to recycle efficiently,' says Sharma, adding that battery chemistry is constantly evolving, meaning recyclers are collecting batteries that 'have a mix of so many different chemicals'. Some battery chemistries are emerging as dominant, however, and Sharma suggests that the next few years will see the emergence of a 'more homogenous' battery waste stream that will be easier to organise and recycle. '[Once] you have more batteries available to recycle, then you have the scale to be able to do so effectively,' he adds. 'Once you start to standardise the battery chemistry, you can then start to think about really minimising the steps of recycling.' Some progress is being made. There is also an historical precedent, with the lead-acid battery industry providing a model Australia can learn from. In January 2022, the Battery Stewardship Council introduced a levy scheme in partnership with manufacturers, lifting the recovery rate of small batteries from less than 8% to more than 16% within six months. The Australian Government also recently announced its National Battery Strategy, laying out ways to support its domestic battery industry as it grows. As Australia works to close the loop, embedding sustainability throughout the supply chain will be crucial. With environmental, social and governance standards becoming more stringent, shareholders and consumers alike will be paying close attention. Saydam warns that Australia's mines will have to integrate more sustainable practices into operations to not only meet future lithium demand but also become a 'key player' in the global transition to a low-carbon economy. 'Investment in innovation – such as direct lithium extraction and low-carbon refining technologies – is vital to reduce the environmental footprint and support a circular economy,' Saydam says. 'The industry must navigate global market volatility and advocate for clear national policies that support sustainable growth. 'Addressing these challenges holistically will be key to ensuring that Australia can scale its lithium production in a responsible and globally competitive manner,' he adds. Australia has already begun to develop local refining capacity and domestic battery recycling initiatives. Still, significant hurdles remain in meeting the fast-rising global demand. Optimising lithium extraction and processing will require a coordinated blend of legislative reform, technological advancement and strategic investment, according to Saydam. 'Legislative frameworks need to be strengthened to encourage sustainable and efficient practices,' he says. 'This includes creating clear, stable policies that incentivise domestic value-adding activities such as refining and battery material production, rather than solely exporting raw materials. 'Regulatory settings should also enforce strict environmental standards to ensure water use, waste management and emissions are responsibly managed, while fast-tracking approvals for sustainable technology deployment,' Saydam continues. Enhancing community and Indigenous engagement, investing in workforce upskilling, and encouraging collaboration between academia, industry and government were also highlighted as key to long-term success. As Saydam concludes: 'In essence, the long-term success of Australia's lithium industry depends on a holistic approach that integrates sustainability, innovation and strategic positioning in the global value chain.'

LNG Emissions Could Fall 60% With $100 Billion Invest
The International Energy Agency said LNG emissions could be slashed by over 60% using today's technologyif investors pony up roughly $100 billion, the agency's latest report shows. The IEA pegs annual greenhouse gases from the global liquefied natural gas supply chain at about 350 million tonnes of CO?-equivalent and estimates $100 billion in upfront capital would fund electrification, methane-leak mitigation and CCUS across all viable LNG facilities. Roughly 70% of those emissions come from CO? released during combustion or venting, while the remaining 30% stems from unburnt methane slipping into the atmosphere. Despite cleaner life-cycle footprintsmore than 99% of LNG consumed in 2024 emits less than coal and on average yields about 25% lower emissionsthe IEA warns that comparing LNG only to coal sets the bar too low given broader decarbonization opportunities. Beyond electrification and CCUS, boosting process efficiency and deploying carbon capture at liquefaction plants could drive down both CO? and methane output. Major LNG producers like Shell (NYSE:SHEL), ExxonMobil (NYSE:XOM), TotalEnergies (NYSE:TTE) and Chevron (NYSE:CVX) are positioned to benefit from, or be challenged by, the shift toward cleaner operations. Why it matters: Energy investors need to weigh potential returns from financing clean-tech upgrades against regulatory pressure and emerging carbon-pricing regimes that could penalize high-emission producers. Closing: Markets will be watching next month's shareholder meetings at SHEL, XOM and CVX for any new clean-energy commitments or capital-allocation shifts to back the IEA's $100 billion roadmap.
