The global automotive industry is undergoing a significant paradigm shift. The transition to electric vehicles (EVs) is not just about replacing internal combustion engines with electric motors. The primary focus is now shifting toward the materials used to build these vehicles.

Materials scientists and manufacturers are now seeking sustainable alternatives. The use of bio-based materials and recycled content has become key to reducing carbon footprints. In Indonesia, this trend is gaining strong momentum through intensive research and government policies that support the green industry [1].

The potential of biomaterials in automotive components

The utilization of biomaterials offers innovative solutions for electric vehicle manufacturers. Indonesia, with its wealth of natural resources, possesses a significant competitive advantage. Palm oil fibers, bamboo, and pineapple fibers are currently being researched in depth by the National Research and Innovation Agency (BRIN) for automotive applications [2].

These materials are not only environmentally friendly but also offer a lighter weight. Reducing vehicle weight is crucial for the energy efficiency of EV batteries. Furthermore, the use of natural fibers can reduce dependence on non-renewable petroleum-based plastics.

Natural rubber innovation for tire efficiency

The tire sector is also undergoing a transformation through the use of local natural rubber. As the world’s largest producer of natural rubber, Indonesia plays a strategic role. Tires specifically designed for electric vehicles require low rolling resistance to maximize driving range [3].

This innovation combines advanced polymers with natural rubber to improve durability. Manufacturers are now focused on developing compounds that are more resilient and environmentally friendly. This proves that local materials can compete in the high-tech market.

Circular economy and battery recycling

Sustainability in EV production is incomplete without a battery recycling system. Lithium-ion battery waste contains valuable metals such as nickel, cobalt, and lithium. Recycling facilities in industrial areas like Morowali are now becoming centers for processing “black mass” [4].

This recycling process supports the principles of a circular economy. By reclaiming critical metals, manufacturers can reduce the need for new mining. You can learn more through an analysis of the costs and benefits of electric vehicle battery recycling in Indonesia to understand its economic efficiency.

Government policy and TKDN targets

The Indonesian government has established clear regulations through Presidential Regulation No. 55 of 2019. This policy encourages the acceleration of the battery-based electric vehicle program nationwide. The Domestic Component Level (TKDN) target of 80% by 2030 is a primary driver for local innovation [5].

Automotive manufacturers are now required to partner with the domestic supply chain. This opens up significant opportunities for bio-based material producers to enter the automotive market. Integrating local materials into EV design will strengthen Indonesia’s position as a key player in Southeast Asia.

Challenges in adopting new materials

Despite having great potential, the adoption of new materials faces technical challenges. The standardization of the mechanical strength of biomaterials for structural components remains a primary research focus. Manufacturers must ensure that these materials meet strict automotive safety standards.

Production cost efficiency at scale is also an obstacle. Developing standardized plastic and battery recycling facilities requires significant investment. However, collaboration between academia and industry can accelerate this transition.

The future of green manufacturing in Indonesia

Indonesia has a golden opportunity to become a hub for green component manufacturing. Its biological wealth and abundant nickel reserves provide a strong foundation. By focusing on advanced materials research, manufacturers can create more sustainable products.

The implementation of green technology in EV production will increase the competitiveness of Indonesian products in the global market. This step is also in line with international commitments to reduce carbon emissions. The future of the Indonesian automotive industry lies in our ability to process resources wisely.

Conclusion

Bio-based and recycled materials are the future of the electric vehicle industry. The integration of materials research and government policy will accelerate this transition. Indonesia has all the necessary components to lead this transformation in the regional area.

Manufacturers must continue to innovate in the utilization of local materials. With the right technological and policy support, the Indonesian automotive industry will become greener and more sustainable. Let us support the development of recycled material market development for electric vehicles for a better future.
