Thailand EV Battery Recycling Study Favors Integrated Model

The Electric Vehicle Association of Thailand (EVAT), the German Agency for International Cooperation (GIZ), and the Thailand Development Research Institute (TDRI) have released a study on Thailand EV battery recycling and second-life facilities, as reported on October 7, 2026. The study examines how the country can establish facilities that recycle EV batteries and give suitable used units a second life, ahead of a growing wave of retired batteries.

Projected Volume of Discarded EV Batteries

The study projects that discarded EV batteries in Thailand will total around 9,349 tons in 2030. By 2038, the volume is expected to rise to 73,855 tons, nearly eight times the 2030 figure. This steep increase underlines why the researchers call for preparation for end-of-life batteries, since volumes grow sharply over just eight years. The projection sets out the scale of material that recycling and reuse facilities would eventually need to handle.

Why Recycling Alone May Fall Short Financially

The findings indicate that a recycling-only operation in Thailand may not be financially viable. Instead, the study points to an integrated process that combines battery sorting, reuse of suitable units for energy storage, and recycling of unsuitable batteries at facilities that meet the required standards. This combined approach could yield better business returns by allowing batteries that remain suitable to be reused before the unsuitable ones are recycled.

Health Checks Required Before Battery Reuse

Before any battery is reused, it must undergo checks of its history and state of health (SoH). These checks determine which units are suitable for energy storage applications and which should be sent for recycling. Because the integrated model depends on sorting batteries correctly, the assessment step sits at the center of the process, linking reuse and end-of-life recycling into one workflow.

Building a Domestic Battery Ecosystem

The study calls for battery recycling facilities to be established promptly in preparation for future battery replacements. It also aims to help develop Thailand's battery ecosystem through regulatory development, investment, and environmentally responsible management. Together, these goals tie facility planning to the rules, funding, and management practices that would support a stronger battery sector over time.

Industry Impact & Outlook

The study's findings suggest that automakers, battery suppliers, and energy-storage developers operating in Thailand may need to plan for end-of-life batteries earlier than a recycling-only model would require. An integrated approach could open a path for second-life storage projects alongside material recovery, while the call for regulatory development points toward clearer rules for handling and processing. Recyclers, EV makers, and policymakers shaping the battery ecosystem are likely to be most affected. The likely next steps are facility investment and standards-setting, although timing will depend on regulation and the funding that follows.

Frequently Asked Questions

How much EV battery waste does the study project for Thailand?
The study projects that discarded EV batteries in Thailand will total around 9,349 tons in 2030, rising sharply to 73,855 tons by 2038, according to the research released by EVAT, GIZ, and TDRI. The projection shows how quickly retired batteries may accumulate over a period of just eight years. It also explains why the study urges facilities to be established promptly, so that capacity for reuse and recycling is ready before large numbers of batteries are replaced.

Is a recycling-only operation financially viable?
The findings indicate that a recycling-only operation may not be financially viable, and that an integrated process could deliver better business returns than recycling on its own. That integrated process involves sorting batteries, reusing suitable units for energy storage, and recycling unsuitable batteries at facilities that meet the required standards. Combining these steps allows each battery to follow the route that best matches its condition, rather than being sent straight to recycling.

What checks are required before an EV battery is reused?
Before reuse, EV batteries must undergo checks of their history and their state of health, commonly abbreviated as SoH, to confirm whether a given unit is suitable for further use. Units that pass can be reused for energy storage, while batteries that are unsuitable are recycled at facilities meeting the required standards. This assessment step is therefore central to the integrated approach described in the study, because it decides whether a battery enters second-life use or goes to recycling.
