The electric vehicle industry in Indonesia is undergoing a major transformation. With the world’s largest nickel reserves, Indonesia is now positioning itself as a key player in the global battery supply chain. However, the growth in electric vehicle adoption brings new challenges regarding future battery waste management.

Implementing circular economy principles is a crucial solution for maintaining the sustainability of this ecosystem. This strategy focuses on minimizing the extraction of new raw materials and systematically reducing the accumulation of hazardous waste [3].

Understanding the potential of used batteries

Electric vehicle batteries that reach the end of their service life do not necessarily become waste. When battery capacity drops to 70% or 80%, the batteries are indeed no longer optimal for vehicle mobility. However, these batteries still possess highly valuable energy storage capacity for stationary applications [1].

The circular economy strategy for electric vehicle batteries allows these batteries to have a second life. This process extends the battery’s service life by an additional 5 to 10 years before it finally enters the chemical recycling stage.

Utilizing batteries for energy storage

Reuse or second-life battery applications are a main pillar of the circular strategy in Indonesia. Used batteries can be integrated into large-scale energy storage systems or Battery Energy Storage Systems (BESS).

Key applications of this technology include:

  • Energy storage for solar power plants (PLTS) in remote areas.
  • Backup power or Uninterruptible Power Supply (UPS) for data centers and industrial facilities.
  • Additional power storage for public electric vehicle charging stations (SPKLU).

This step greatly assists the government in accelerating the clean energy transition in 3T (frontier, outermost, and underdeveloped) regions [3].

Critical material recycling strategies

Recycling is the inevitable final stage to return valuable materials back into the production chain. Through this process, critical metals such as nickel, cobalt, lithium, and manganese can be recovered. Indonesia is currently pushing for the development of integrated battery recycling facilities [2].

There are two main technological methods that are of interest to the industry:

  • Hydrometallurgy: A chemical solution-based extraction method with a recovery efficiency of over 90%.
  • Pyrometallurgy: A high-temperature smelting process to recover base metals, although it requires higher energy consumption.

The Indonesian government, through the Indonesia Battery Corporation (IBC), continues to design a roadmap so that this ecosystem can operate independently within the country [1].

Regulation and producer responsibility

Battery waste management in Indonesia is strictly regulated under Government Regulation (PP) No. 22 of 2021. Used lithium-ion batteries are categorized as Hazardous and Toxic Waste (B3) that require special handling [4].

The Extended Producer Responsibility (EPR) policy is an important instrument. This policy requires automotive manufacturers to take responsibility for the collection of batteries that have reached the end of their service life. This ensures that battery waste does not pollute the environment and remains within a productive economic cycle [4].

The future of Indonesia’s battery ecosystem

The success of the battery circular economy depends heavily on collaboration between the government, manufacturers, and technology innovators. With the presence of electric vehicles and government incentive policies in Indonesia, the demand for batteries will continue to increase exponentially.

Investment in environmentally friendly recycling technology will strengthen Indonesia’s position as a global battery manufacturing hub. Furthermore, this will reduce future dependence on raw material imports [5].

As a strategic step, industry players need to start preparing logistics infrastructure for the collection of used batteries. Without an efficient collection system, the economic potential of recycled materials will not be maximized [4].

By implementing recycling and reuse strategies, Indonesia is not only protecting the environment. We are also building a resilient, efficient, and sustainable industrial foundation for the long term [3].

More Information

  1. Circular economy: An economic model that aims to minimize waste and maximize resource use through continuous recycling, repair, and reuse of materials within the production cycle.
  2. Hydrometallurgy: A process of extracting metals from ore or battery waste using liquid chemical solvents, known to be more efficient and environmentally friendly than high-temperature smelting methods.
  3. BESS (Battery Energy Storage System): An energy storage system that uses batteries to store electricity from renewable sources and release it when needed to stabilize the power grid.
  4. Hazardous and Toxic Waste (B3): Materials that, due to their nature or concentration, can pollute the environment, thus requiring special management in accordance with Indonesian government regulations.
  5. Extended Producer Responsibility (EPR): An environmental policy that requires producers to take responsibility for the entire life cycle of their products, especially at the end-of-life or disposal stage.
