Electric vehicle (EV) batteries are packed with valuable materials like lithium, cobalt, and nickel. Recycling these not only reduces waste but also slashes greenhouse gas emissions by 58–81% and cuts energy use by up to 89% compared to mining new materials. By 2040, recycled batteries could supply over 50% of the lithium and nickel needed globally.
Recycling EV batteries isn’t just about waste management - it’s about creating a sustainable future for electric transportation.
As U.S. policies continue to evolve, the focus on better battery recycling practices becomes increasingly important. Understanding how EV batteries are recycled helps vehicle owners make more informed decisions, reducing the environmental impact when their cars reach the end of their lifecycle. The recycling process uses advanced techniques designed to recover valuable materials while minimizing waste.
Mechanical recycling serves as the starting point for processing EV batteries. This step involves breaking down batteries through physical methods, preparing the materials for further refinement. Though labor-intensive, it yields high-purity materials for later stages. The process generally includes six steps: collection and sorting, dismantling, size reduction, component separation, purification, and waste management. Many modern facilities now incorporate automation and AI to streamline disassembly and reduce risks to workers. To aid recycling efforts, manufacturers are encouraged to design battery packs that are easier to take apart.

Once the mechanical process is complete, chemical recovery methods are used to extract valuable metals.
Chemical recovery, often referred to as hydrometallurgy, uses acids and solvents to extract metals like lithium, cobalt, and nickel from the materials processed in the mechanical stage. These metals are dissolved into liquid solutions and later precipitated out for reuse.
Michael Machala, PhD '17, highlighted a compelling fact: mining active metals typically involves transporting materials an average of 35,000 miles, whereas recycling batteries in California reduces this to just 140 miles.
Compared to pyrometallurgy, hydrometallurgy consumes less energy. However, it does produce sulfate waste that requires additional treatment. Despite this drawback, the process is highly effective, recovering most of the key components in lithium-ion batteries. If scaled effectively, recycled batteries could meet a significant portion of global demand by 2040 - 60% of cobalt, 53% of lithium, 57% of manganese, and 53% of nickel.
As these methods continue to improve, emerging technologies are pushing the boundaries of what’s possible in battery recycling.
The battery recycling industry is rapidly advancing, with new technologies offering more efficient and environmentally friendly solutions. One standout innovation is direct recycling, which preserves the original structures and chemical compositions of battery materials, cutting down on energy use and waste. By 2025, the global lithium-ion battery recycling industry is expected to reach a capacity of 1.6 million tons per year, with plans to exceed 3 million tons annually in the future. Additionally, the EV Battery Reuse and Recycling Market is projected to hit $28.1 billion by 2029.
Recent collaborations are driving progress. For instance, Hydrovolt launched an automated battery recycling line in October 2024, while Volkswagen Group UK expanded its partnership with Ecobat in February 2024. Other notable partnerships include BASF teaming up with American Battery Technology Company. Digital tools are also playing a transformative role by improving material tracking, automating sorting and disassembly, and optimizing recycling schedules. Emerging methods, such as deep eutectic solvent (DES) processing and microbe-based leaching, are still in development but show great potential.
These advancements are making battery recycling a more reliable source of raw materials. By 2040, recycling efforts could supply over half the lithium and nickel needed for EV batteries and contribute 10% to 40% of the raw materials required for new battery production.
The United States is navigating a changing landscape when it comes to EV battery recycling. Unlike the European Union, which has detailed regulations in place, the U.S. relies on existing environmental laws and emerging state-led initiatives to address the increasing need for responsible battery disposal. Let’s take a closer look at the federal guidelines shaping these practices.
Currently, there’s no federal law specifically requiring EV battery recycling. However, the Resource Conservation and Recovery Act (RCRA) does apply to end-of-life lithium-ion batteries. On May 24, 2023, the Environmental Protection Agency (EPA) issued a memo clarifying how hazardous waste rules relate to lithium-ion batteries. The memo noted that "most lithium-ion batteries are likely hazardous waste at end of life and that they can be managed under the … universal waste" category until they reach a designated recycling facility.
This classification has significant implications for businesses and recycling centers. Under RCRA’s "universal waste" rules, companies are encouraged to handle lithium-ion batteries using a simplified framework that prohibits their disposal in landfills.
Another federal regulation, the Mercury-Containing and Rechargeable Battery Act (The Battery Act), mandates that used nickel-cadmium (Ni-Cd) and small sealed lead-acid (Pb) batteries be managed as Universal Waste under 40 CFR Part 273. This ensures these batteries are sent for recycling instead of being improperly discarded.
In addition, the Bipartisan Infrastructure Law is fueling new federal initiatives. It tasks the EPA with developing best practices for battery collection and creating labeling guidelines by September 30, 2026. The law has allocated $10 million for improving collection efforts and $15 million for the development of labeling standards.
While federal policies are still taking shape, several states have stepped up with their own battery recycling programs, often placing more responsibility on manufacturers. For example, Washington, D.C., introduced a requirement in 2022 for battery producers to join a "battery stewardship organization".
California has taken a leading role in EV adoption and battery recycling policies. Recognizing the state’s high EV usage, the California Environmental Protection Agency (CalEPA) formed the Lithium-ion Car Battery Recycling Advisory Group in 2019. This group provides recommendations to the Legislature on how to improve lithium-ion battery recovery and recycling efforts.
New York is also making strides by combining energy storage incentives with initiatives to promote EV charging and clean vehicle adoption. In February 2025, the New York Public Service Commission approved the New York State Energy Research and Development Authority’s (NYSERDA) draft Retail and Residential Implementation Plan. This plan aims to achieve 6 GW of energy storage by 2030, backed by nearly $2 billion in incentives.
These state-level efforts go beyond environmental benefits. By embracing battery recycling and reuse, the demand for new mining of critical minerals could drop by as much as 40%, while greenhouse gas emissions might see reductions of up to 80%. Additionally, second-life applications for EV batteries could generate more than 200 GWh of power by 2030 - enough to supply electricity to roughly 18,500 American homes for an entire year.
The evolving mix of federal and state regulations presents both opportunities and challenges for EV stakeholders, including owners, manufacturers, and recycling facilities. As the Union of Concerned Scientists points out, "As EV sales grow, proper reuse and recycling of the batteries and materials they're made from will require proactive, science-based policy to create a sustainable and ethical electrified transportation system". These policies collectively aim to strengthen a circular economy, underscoring the essential role of EV battery recycling in advancing sustainable transportation.
When your EV battery reaches the end of its life, recycling it responsibly is crucial - not just for protecting the environment but also for recovering valuable materials. In 2020 alone, around 550,000 EV batteries reached the end of their usable life, and this number is expected to skyrocket to 150 million by 2035. Interestingly, even when a battery is no longer fit for powering a vehicle, it often retains 70–80% of its storage capacity, making it suitable for reuse or recycling.
There are a few reliable ways to dispose of your EV battery:
"Unlike liquid hydrocarbons, whose energy content is gone after they're burned as gasoline, an atom of cobalt is an atom of cobalt regardless of how many batteries it's been in. So, end-of-life EV batteries offer a future source of those valuable metals, already extracted from the ground and neatly packaged in a box." - John Voelcker, Contributing Editor
Dealerships are increasingly stepping in to simplify battery recycling for EV owners. Many now include recycling as part of trade-in and service programs, offering transparent and certified processes.
"The consumer battery recycling program Audi launched with Redwood Materials was created with the idea that we all can contribute to a more sustainable world." - Spencer Reeder, Audi of America Director Government Affairs & Sustainability
If you’re in Southern California, dealerships like Premium Autos Inc in Norco and El Monte can guide you through proper battery disposal. Their expertise in electric vehicles ensures they can recommend manufacturer-specific recycling programs and other options.
Finding a certified recycling center is easier than ever, thanks to online tools and expanded infrastructure. Websites like Earth911 and Call2Recycle allow you to search for facilities by location and battery type.
Additionally, major retailers like The Home Depot, Lowe's, and Staples have partnered with recycling programs to serve as drop-off points for smaller batteries. While EV batteries require specialized facilities, these partnerships improve accessibility for other battery types.
The recycling infrastructure is also growing. For instance, in March 2023, Ascend Elements opened a facility in Covington, Georgia, capable of processing batteries from 70,000 EVs annually. However, since EV batteries store significantly more energy than smaller hybrid batteries - 20 to 100 times more - they require specialized handling and processing. Always verify that the center you choose is equipped and certified for EV battery recycling.
"Recycling should make it cheaper to make new batteries, and as we drive down the cost of batteries, more people can drive EVs, and that's good. It can help decarbonize the world." - Jeffrey Spangenberger, chemical engineer at Argonne National Laboratory
The U.S. Department of Energy is also playing a role by supporting initiatives like the Lithium-Ion Battery Recycling Prize, which aims to improve the collection, sorting, and transportation of spent batteries. These efforts are paving the way for more accessible and efficient recycling options for EV owners across the country.
Understanding your recycling options not only helps the environment but also contributes to a more sustainable and resource-efficient future.
Recycling EV batteries plays a key role in creating a circular economy by turning waste into reusable resources. Instead of letting used batteries pile up in landfills, recycling extracts essential materials that can be used to manufacture new batteries. This reduces the demand for mining, which often has harmful environmental effects. Harry Bajaj, CEO of Mobec Innovation, highlights this potential:
"Battery recycling is poised to transform the EV industry by turning waste into valuable resources."
By 2040, the volume of used EV batteries could reach a staggering 7.8 million tons annually. Recycling not only addresses waste management challenges but also creates a steady supply of critical materials for battery production. This process supports sustainability while offering notable economic advantages.
The financial case for battery recycling is hard to ignore. Recycled lithium-ion batteries can recover up to 95% of the materials needed to produce new batteries. By 2040, recycling could provide 60% of cobalt, 53% of lithium, 57% of manganese, and 53% of nickel globally. This translates into billions of dollars in recovered material value while easing the demand for environmentally taxing mining operations.
In fact, saving these critical materials could cut costs by as much as $25 billion annually by 2040. Projections show that the global battery recycling market could grow to $11.83 billion by 2030. J.B. Straubel, CEO of Redwood Materials, emphasizes the resiliency of these materials:
"The metals in batteries don't change or degrade, so the materials from old batteries can be made into new batteries without any tradeoffs in performance or battery life."
Advanced recycling technologies are achieving impressive recovery rates. For instance, a Chinese study reports success rates of 99.99% for lithium, 97% for nickel, 92% for cobalt, and 91% for manganese. Recycled materials are expected to supplement cobalt supply by 4% in 2030 and over 50% by 2040, reducing the strain on new mining efforts.
The environmental benefits of battery recycling are equally compelling. Recycling lithium-ion batteries produces 58% to 81% fewer greenhouse gas emissions compared to mining and processing new materials. Additionally, while traditional mining and refining operations for battery metals involve transport distances of roughly 35,000 miles, recycling reduces this figure to about 140 miles - dramatically cutting emissions and costs.
William Tarpeh, Assistant Professor of Chemical Engineering at Stanford University, highlights the potential of recycling to reshape the future:
"This study, I think, tells us that we can design the future of battery recycling to optimize the environmental benefits. We can write the script."
Recycling also prevents hazardous materials from seeping into soil and water, reducing risks to both the environment and human health. Incorporating recycled materials into new batteries can lower lifecycle emissions by 7–17%, and since recycling generates 80% fewer emissions than mining, the cumulative environmental benefits are substantial.
Looking ahead, increased recycling of critical minerals could cut the need for new mining by up to 40% by mid-century. If full material recovery is achieved, approximately 16 million tons of CO₂ emissions could be avoided annually by 2040.
The EV battery recycling industry is on the brink of massive growth. By 2029, the global market for electric vehicle battery reuse and recycling is expected to jump from $8.0 billion in 2024 to $28.1 billion, with an impressive annual growth rate of 28.5%. Looking further ahead, estimates suggest it could grow from $0.54 billion in 2024 to $23.72 billion by 2035.
This growth reflects the pressing need for sustainable solutions as electric vehicle adoption accelerates. Right now, only about 5% of lithium-ion batteries are recycled correctly. However, recycling could meet over half the demand for lithium and nickel for EV batteries by 2040. In the next 5–10 years, recycled materials could supply between 10% and 40% of the raw materials needed for new EV batteries. This demand is driving advancements in recycling technologies to recover materials more efficiently.
Emerging innovations are already making a difference. Advanced recycling methods can now recover up to 95% of the essential minerals and materials required for new batteries. Direct recycling processes are improving overall efficiency. Additionally, new technologies like "debond on demand" and cell-to-pack designs are simplifying the dismantling and recycling of batteries.
Automakers are also stepping up. In October 2024, Mercedes‑Benz launched Europe’s first battery recycling facility with an integrated mechanical-hydrometallurgical process. Redwood Materials has partnered with BMW North America to recycle batteries from the BMW group and with Volkswagen Group of America to handle end-of-life EV batteries from VW and Audi models.
Government policies are playing a critical role in accelerating these changes. By 2027, 80% of the value of critical minerals in EV batteries must come from North America or nations with U.S. free trade agreements. To support this shift, the federal government is making significant investments, including a $2 billion conditional loan commitment to Redwood Materials in early 2023 to expand its battery materials campus in Nevada.
These efforts highlight the collaboration between industry and government to promote sustainable EV growth. As Pedro Pacheco, Vice President of Research at Gartner Inc., explains:
"As material prices surge, manufacturers may shift toward recycling as a more cost‑effective alternative to producing batteries from raw materials."
Automation and AI are also transforming the recycling process, making it faster and more efficient. Christian Marston, president and chief operating officer of Altilium, underscores the importance of this shift:
"We have to remove that myth that batteries go to landfill."
Recycling EV batteries doesn’t just cut waste - it also slashes greenhouse gas emissions by 58% to 81% and uses 77% to 89% less energy compared to mining and processing raw materials. The future of EV battery recycling is about more than managing waste; it’s about creating a sustainable backbone for the electric vehicle revolution.
Recycling electric vehicle (EV) batteries offers a powerful way to lessen the environmental toll compared to mining fresh materials. It slashes greenhouse gas emissions, water usage, and energy consumption by as much as 81%, 88%, and 89%, respectively. These reductions play a vital role in addressing climate change and curbing the ecological harm often associated with mining operations.
Another major advantage of recycling is the recovery of valuable metals like lithium, cobalt, and nickel. This not only decreases the demand for resource-heavy mining but also helps protect natural ecosystems. By prioritizing battery recycling, we can create a more sustainable and ethically responsible EV industry while maintaining a reliable supply of key materials for future battery production.
New advancements, such as direct recycling, are reshaping how EV batteries are recycled by recovering and reusing essential materials without altering their chemical structure. Unlike older methods like pyrometallurgy or hydrometallurgy, direct recycling requires less energy and fewer processing steps, making it a more efficient and eco-conscious approach.
This method preserves important materials like lithium and nickel, achieving higher recovery rates while cutting down on waste. With the rising demand for EV batteries, direct recycling is becoming a key part of extending the lifecycle of lithium-ion batteries, helping to conserve resources and lessen environmental harm.
Federal and state policies in the U.S. are playing a pivotal role in shaping the future of EV battery recycling by encouraging sustainable practices and holding manufacturers accountable. A great example of this is the Bipartisan Infrastructure Law, which backs the creation of a national Extended Producer Responsibility (EPR) framework. This framework sets clear recycling targets, mandates reporting, and requires manufacturers to take responsibility for their batteries throughout their entire lifecycle.
Another key piece of legislation, the Strategic EV Management Act, focuses on reusing and recycling EV batteries from federal vehicle fleets. It promotes collaboration between government agencies, manufacturers, and recycling companies. The goal? To boost recycling rates, minimize environmental harm, and reduce dependency on international sources for critical battery materials. These policies are part of a larger push to support sustainability while driving economic growth in the rapidly evolving EV industry.
