EV cars and the rise of EV battery waste: A growing circular economy challenge
Electric vehicles are accelerating the transition to low-carbon transport. What was once a niche technology is now mainstream, with global EV sales exceeding 17 million vehicles in 2024 and accounting for more than 20% of all new car purchases (International Energy Agency (IEA)).
This growth is essential to reducing emissions, but it also brings a new and less visible challenge into focus: EV battery waste.
Lithium-ion batteries sit at the centre of the EV transition. They are highly effective, but are also complex products with a finite lifespan. Over the next decade, millions of these batteries will reach the end of life, creating one of the fastest-growing waste streams in the clean energy transition.
This raises a simple but important question. How do we manage EV batteries to protect resources, reduce waste, and support a more circular economy?
In this blog, we explore the rapid growth of EV vehicles, the challenges of EV battery waste, how regulation is reshaping the landscape, and what the future is for this complex waste stream.
Let’s dive in.
The rapid growth of electric vehicles
The pace of EV adoption is already shaping what comes next. With sales forecast to exceed 20 million vehicles in 2025 and around 58 million EVs already on the road globally, the volume of batteries entering the market is increasing rapidly (International Energy Agency).
Because most EV batteries last between 10 and 15 years, we are now approaching a turning point. The first large wave of batteries will soon reach the end of life at scale.
Industry forecasts highlight the scale of this shift. Global EV battery waste could reach 11 million tonnes per year by 2035, according to the Global Battery Alliance, while total lithium-ion battery waste may exceed 30 million tonnes annually by 2040 based on International Energy Agency estimates.
This is not a distant issue. It is a direct consequence of growth.
A complex but valuable waste stream
EV batteries present a unique challenge. They are large, often weighing several hundred kilograms, and have complex combinations of materials. If handled incorrectly, they can pose environmental and safety risks.
At the same time, they contain valuable resources, including lithium, cobalt and nickel. These materials are energy-intensive to extract and increasingly important for global supply chains.
This creates a clear circular opportunity. Instead of treating batteries as waste, they can be seen as a resource that retains value beyond first use.
However, today’s systems are not yet operating at that level. Recycling rates for lithium-ion batteries remain low, with estimates suggesting they sit at around 5%, as highlighted by The Sustainable Investor.
Without action, millions of tonnes of valuable material could be lost each year.
Extending value through circular systems
A more circular approach to EV batteries starts by recognising that end of life does not always mean end of use.
Many batteries retain usable capacity when they are no longer suitable for vehicles. These can be repurposed for energy storage, helping to balance renewable energy systems and extend the life of the materials.
Where reuse is not possible, recycling plays a critical role. Technologies such as pyrometallurgical and hydrometallurgical processing can recover key materials and return them to the supply chain.
In a circular system, these materials are not lost. They are recovered, reused, and fed back into the production of new batteries, reducing reliance on virgin resources and lowering overall environmental impact.
Regulation is reshaping the landscape
Policy is now accelerating change, particularly across Europe.
The EU Batteries Regulation introduces stricter requirements across the full lifecycle of batteries, including collection targets, recycled content requirements, and digital battery passports, as outlined by the European Commission.
For UK businesses, the impact is significant.
Although the UK is no longer part of the EU, it remains closely connected through supply chains, particularly in automotive manufacturing. Businesses that export to the EU, import components, or operate across both regions will need to align with these requirements in practice.
This means the EU regulation is likely to influence how EV batteries are managed in the UK, regardless of domestic policy.
We are already seeing a similar direction in UK reforms, such as Extended Producer Responsibility, which shifts the cost and responsibility of waste management towards producers and aims to improve recycling outcomes.
For organisations, this creates a more complex regulatory environment, but also a clearer incentive to invest in circular systems.
The scale of future EV battery waste
By the mid-2030s, studies predict that EV battery waste will become one of the fastest-growing waste streams globally (Mckinsey, 2023).
Further studies estimate that the volume of battery materials available for recycling could reach around 1.4 million globally by 2030, with further predictions of 7 million tonnes by 2040 (Science Direct, 2025).
To put these findings into context, studies indicate that global battery capacity is projected to exceed 3 terwatt hours (TWh) by 2030, compared to the reported 1 TWh in 2024 (Science Direct, 2025).
Although lithium-ion batteries are valuable, their recycling rates are still quite low. It is predicted that recycling rates are between 5% and 10%. However, there are inconsistencies in the reporting. This had led to suggestions that new legislation, like Extended Producer Responsibility, could significantly improve visibility (The Sustainable Investor, 2024).
Meeting this challenge will require collaboration across the value chain. Manufacturers, policymakers, and waste management providers all have a role to play in building the infrastructure and systems needed to recover materials safely and efficiently.
For businesses, the priority is to act early. Understanding future waste streams, preparing for regulatory change, and exploring circular solutions will be essential.
Turning challenge into opportunity
Electric vehicles are a critical part of the transition to a lower-carbon future. But their long-term success depends on how we manage what comes next.
EV batteries represent both a challenge and an opportunity. If handled correctly, they can support more resilient supply chains, reduce reliance on raw materials, and help close the circularity gap.
Moving from a linear approach to a circular one is not just about managing waste. It is about recognising value, keeping materials in use, and building systems that work for the long term.
That is where real progress happens.

Carbon impact
Producing new battery materials from mining is far more energy-intensive than recovering them through recycling.
Developing circular recovery systems is therefore essential to increase the environmental benefits of electric transport.
Circular economy strategies offer a pathway to managing EV battery waste sustainably.
These approaches focus on keeping materials in use for as long as possible.
Second-life applications
Some EV batteries can be repurposed for:
- grid energy storage
- renewable energy balancing
- industrial power systems
Battery recycling
Advanced recycling processes can recover valuable materials such as:
- lithium
- cobalt
- nickel
- copper
- aluminium
Recovering these materials reduces reliance on new mining while supporting more resilient supply chains.
Closed-loop material systems
In a circular battery economy, recovered materials are used to manufacture new batteries, reducing the need for virgin resource extraction.
The current landscape for recycling EV batteries is split between two methods. The two main processes taking place are: Pyrometallurgical and Hydrometallurgical.
Pyrometallurgical
In a pyrometallurgical process, each battery is broken down into tiny pieces and sent for incineration (burned). Each dismantled battery is processed at high temperatures to create a material called ‘black mass’, a byproduct containing valuable metals such as lithium, cobalt and nickel. These materials can then be refined further and recovered for reuse.
Hydrometallurgical
In a hydrometallurgical recycling process, chemical solutions are used to dissolve battery materials into a liquid form. This allows valuable elements such as lithium, cobalt and nickel to be carefully separated and recovered for reuse.
Both hydrometallurgical and pyrometallurgical recycling methods require specialist facilities and strict operational controls to ensure safe handling, protect workers, and minimise environmental impact while recovering valuable resources from end-of-life batteries.
EV batteries can be reused in second-life energy storage systems or recycled to recover valuable materials such as lithium, cobalt and nickel.
Yes. Lithium-ion batteries are recyclable, although specialised facilities and processes are required to recover materials safely and efficiently.
Industry forecasts suggest global EV battery waste could reach over 30 million tonnes annually by 2040 as electric vehicle adoption continues to increase.
Recycling batteries helps recover valuable materials, reduces reliance on mining, lowers environmental impact and supports the development of circular supply chains.
