The electric vehicle (EV) industry is experiencing rapid growth worldwide. As the number of vehicles on the road increases, new challenges arise regarding the management of end-of-life battery waste. Therefore, the global standardization of EV battery recycling processes has become crucial for the sustainability of the automotive sector.

Indonesia, as the owner of the world’s largest nickel reserves, plays a strategic role in this global supply chain. The Indonesian government continues to promote mineral downstreaming to strengthen the battery ecosystem from upstream to downstream [2]. This step includes the development of recycling facilities that meet international standards.

The importance of global standardization for manufacturers

Standardization is key to creating an efficient circular economy. Without uniform standards, manufacturers will face difficulties in managing recycled materials across borders. This also impacts compliance with increasingly stringent environmental regulations in various jurisdictions.

The National Standardization Agency (BSN) in Indonesia is actively adopting international standards such as IEC and ISO [3]. These efforts ensure that battery testing and recycling processes in Indonesia are aligned with global best practices. By following national technical standards, manufacturers can increase the competitiveness of their products in the international market.

Integrated battery ecosystem in Indonesia

Indonesia has formed a strategic consortium through the Indonesia Battery Corporation (IBC) to integrate the entire battery value chain [1]. The main focus of this consortium is to build a battery recycling hub capable of processing materials sustainably. This integration is expected to reduce production costs and significantly lower the carbon footprint.

Additionally, investments from global players such as LG Energy Solution and CATL are accelerating the adoption of advanced recycling technologies domestically [5]. This partnership assists Indonesia in mastering circular EV battery supply chain technology, from mining to recycling, more efficiently.

Hydrometallurgy as the technology of the future

In the recycling process, hydrometallurgical technology is now the preferred choice over pyrometallurgy. This method offers recovery rates for metals such as nickel, cobalt, and lithium of over 95% [4]. Beyond high efficiency, this process also generates significantly lower carbon emissions.

The implementation of this technology at facilities such as those in the Morowali industrial park demonstrates Indonesia’s commitment to environmentally friendly standards. By adopting effective and safe lithium-ion battery recycling technology, the industry can ensure that valuable materials remain within the production cycle.

Regulatory harmonization and trade challenges

The biggest challenge in global standardization is the harmonization of battery waste classification. Used batteries are often categorized as hazardous and toxic waste (B3), which requires special handling in accordance with Ministry of Environment and Forestry (KLHK) regulations [2]. International trade for materials such as black mass requires clear standard agreements to avoid violating the Basel Convention.

Manufacturers must ensure that every stage, from dismantling to chemical extraction, meets strict safety criteria. This harmonization will facilitate the flow of recycled materials between countries without excessive bureaucratic hurdles. Ultimately, this will strengthen the national battery industry ecosystem in the eyes of global investors [4].

Strategic steps for standards organizations

Standards organizations must continuously monitor rapidly changing battery technology developments. Collaboration between countries is essential to develop protocols that are flexible yet strict regarding safety. The following are some strategic steps that can be taken:

  • Adopt global standards for the classification of recycled materials.
  • Enhance certification for local recycling facilities to ensure international recognition.
  • Strengthen research on the efficiency of critical battery material recovery.
  • Promote supply chain transparency through digital tracking systems.

Conclusion

The global standardization of EV battery recycling processes is the foundation for the future of sustainable transportation. Indonesia, with its natural resource advantages and appropriate downstreaming policies, is in a highly favorable position. Through collaboration between the government, manufacturers, and standards organizations, Indonesia can become a leader in the global battery circular economy [5].

Sustainable investment in recycling technology is not only economically beneficial but also preserves the environment. By adhering to international standards, manufacturers can ensure that every battery produced today can be safely processed in the future.
