The battery industry in the United States is undergoing a revolution driven by batteries and the promise of significant benefits for both the environment and the economy. The rapid development of lithium-ion, advanced lead-acid, flow, sodium-ion, and other battery chemistries has contributed to the growth of electric vehicles (EVs) and accelerated the transition to renewable energy sources. Further innovation promises even greater possibilities.
However, every revolution brings disruptions and risks. The increasing popularity of batteries must be accompanied by responsible waste management.
Fortunately, we can learn a lot from one of the most recycling-intensive products in the country – the durable lead-acid battery. The lead-acid battery industry has an unparalleled systematic collection and recycling system. For over 30 years, these batteries have been recycled with an almost perfect recycling rate of 99%, surpassing the recycling rates of other consumer products, according to recent recycling rate studies.
This achievement was not by chance, but the result of deliberate policies and industry commitment to circularity. Recycling lead-acid batteries allows for the recovery of hundreds of millions of pounds of lead and plastic annually, diverting them from landfills, and provides about 90% of the entire domestic demand for lead used in the production of new batteries.
Other industries should adopt and replicate the key strategies of lead-acid battery recycling, such as uniform labeling standards, widely accessible collection points for consumers, bans on improper disposal, and industry-funded transportation and processing networks.
The widespread adoption of these policies among lithium-ion and other new battery chemistries is crucial for further innovation. It will ensure the sustainable growth of a robust domestic battery manufacturing and recycling industry, rather than replacing one environmental challenge with another.
Embedding Battery Recycling in the Foundation
The achievements of lead-acid battery recycling in the industry are directly attributed to forward-thinking policies implemented by the industry in the late 1980s. Companies recognized that recycling should be integrated into the early stages of product design, manufacturing processes, and collection channels, rather than added as an afterthought.
Under the influence of the Environmental Protection Agency (EPA) and environmental groups, battery manufacturers and recyclers reached a consensus on legislation that ensured the availability of collection points where batteries are sold. Within a decade, laws that adopted these basic principles were enacted in nearly 40 states, covering over 80% of the population. These laws included the following:
– Ban on landfill disposal of batteries to prevent leaks.
– Requirement for all battery retailers to accept consumer returns.
– Imposition of the responsibility on manufacturers for transportation and recycling.
– Encouragement of consumer returns through a refundable fee.
These simple but deliberate policies completely transformed battery collection channels and recycling efficiency. Within a few years, the recycling rate of lead-acid batteries increased from below 80% to a consistent level above 99%.
By adopting these proactive policies, the lead-acid battery industry was able to simultaneously develop domestic production and increase the utilization of secondary materials. Today, a robust recycling network supplies over 85% of the demand for lead in new American batteries and drives a $26 billion industry employing 92,000 people, according to the latest economic impact report.
Supporting the Safe Collection of All Chemistries
The vast diversity of battery chemistries serving completely different applications requires consideration of various factors. Implementing rigid legislative policies for all battery chemistries may carry the risk of unintended consequences. We must be careful not to disrupt what already works, such as lead-acid battery recycling, while prudently applying proven policies to new chemistries.
Lithium-ion batteries power innovative devices and technologies, but they can pose a fire hazard and safety risk, especially during recycling. The increasing number of these batteries in the coming decade threatens to contaminate existing lead-acid battery streams. Such cross-contamination can reduce the efficiency of the recycling process, compromise the quality and safety of recovered materials, and put collection workers at risk.
A key element of safe and cost-effective operation of any metal recovery facility is efficiency and continuous flow. Battery Council International members process over 160 million batteries for recycling in North America annually and even larger quantities worldwide. A typical battery recycling facility in the US can process 80 or more automotive batteries per minute.
The lead-acid battery recycling process is highly specialized and refined over the years to be as efficient as possible, with the constant and clean delivery of used batteries. This efficiency is one of the main factors in the success of lead-acid battery recycling. However, when incompatible materials, such as lithium batteries, enter the lead-acid battery recycling process, they can lower the quality of the recovered materials.
Most importantly, contamination of the lead-acid battery recycling stream poses a serious safety risk for workers. Lithium batteries significantly increase the risk of fire and explosions in facilities and for workers if they accidentally enter the lead-acid battery recycling process. This is mainly due to the high energy potential of these batteries and their relatively low tolerance for mechanical damage, such as crushing, which has been part of the proven lead-acid battery recycling process for years.
Every lead-acid battery recycler BCI works with encounters several lithium batteries every day, and all experience adverse incidents when lithium batteries bypass rigorous inspection processes.
The sorting and identification process becomes increasingly challenging as more lithium batteries are designed to mimic lead-acid batteries, and their numbers continue to grow. Our members remain vigilant about their recycling streams and often effectively manage the negative impacts resulting from lithium contamination. However, no facility can handle this challenge alone; cooperation between public officials and private sector representatives is necessary for everyone to contribute to public health and safety.
The additional “ingredients” present in the recycling stream require recyclers to perform additional time-consuming and costly material refining processes to achieve the desired quality of recovered metal. This increases carbon dioxide emissions and energy consumption, as well as the amount of waste generated.
A 99% recycling rate for lead-acid batteries is a tremendous achievement for our industry, and we want to ensure that the broader infrastructure for disposal and recycling of other battery chemistries does not undermine the sustainable development of our industry.
