The electric vehicle (EV) industry in Indonesia is undergoing a major transformation through aggressive downstreaming policies. The Indonesian government is committed to building an integrated battery ecosystem that focuses not only on production but also on long-term sustainability.

The concept of a circular supply chain is the key to ensuring the availability of critical materials. This strategy covers the entire battery life cycle, from nickel ore extraction to the recycling process of valuable materials at the end of their service life.

Upstream foundation: nickel mining and processing technology

Indonesia holds a strategic position with the world’s largest nickel reserves. This natural wealth serves as the primary foundation for the development of nickel, cobalt, and manganese (NCM)-based battery industries.

The government has banned the export of raw nickel ore to encourage domestic value-added processing. Now, low-grade nickel ore is processed using High-Pressure Acid Leach (HPAL) technology to produce Mixed Hydroxide Precipitate (MHP) [1].

HPAL technology allows for the processing of nickel waste into high-value cathode precursor materials. Industrial estates such as the IMIP in Central Sulawesi and the IWIP in North Maluku have become the main hubs for these upstream activities.

Midstream integration: battery cell production in Indonesia

The midstream sector serves as a crucial bridge between raw materials and finished products. Massive investment has flowed into building battery cell factories integrated with global standards.

One significant achievement is the inauguration of an EV battery cell plant by PT HLI Green Power in Karawang. This factory is a collaboration between Hyundai Motor Group and LG Energy Solution [2].

This facility marks a new chapter for Indonesia as a key player in the global battery supply chain. The initial production capacity of 10 GWh will continue to be increased to meet both domestic and export market demand [3].

Realizing a circular economy through recycling

The circular economy is not just a trend, but an operational necessity for modern supply chain management. Battery recycling aims to recover critical metals such as nickel, cobalt, and lithium from used batteries.

This process involves processing battery waste into “black mass,” which is then refined. In this way, dependence on mining new materials can be significantly reduced [4].

Global companies like GEM Co., Ltd. have begun investing in recycling projects in the Morowali industrial estate. This initiative is supported by strict government regulations regarding the management of hazardous and toxic waste (B3) [5].

For analysts, this is an opportunity to delve into critical metal recycling technology that is growing rapidly in Indonesia. Implementing this system will strengthen Indonesia’s position in a global market that demands high sustainability standards.

Environmental challenges and sustainability standards

Despite its great potential, the EV battery supply chain still faces environmental challenges. The management of waste from the HPAL process, known as tailings, requires safe dry stacking methods.

Furthermore, the reliance on coal-fired power plants for smelters is a major concern for international investors. The transition to renewable energy is an absolute step toward lowering the total carbon footprint of battery production.

Supply chain managers must ensure that every stage of production meets Environmental, Social, and Governance (ESG) criteria. Compliance with these standards will facilitate the entry of Indonesian battery products into the increasingly selective European and North American markets.

To understand more about this strategy, you can study the circular economy for electric vehicle batteries, which covers reuse and recycling strategies.

Conclusion for decision-makers

A circular EV battery supply chain is the future of the automotive industry in Indonesia. Integration from upstream to downstream, supported by advanced recycling technology, will create sustainable economic value.

For supply chain managers, the main focus should be directed toward process efficiency and environmental compliance. For analysts, monitoring government policies and technological developments in recycling will be key indicators of the industry’s success.

Indonesia is on the right track to becoming a global EV battery hub. With a strong commitment to sustainability, this ecosystem will provide long-term positive impacts on the national economy.
