Indonesia Launches B50 Biodiesel, Claims Superior Performance and Environmental Benefits

Indonesia has officially launched its mandatory B50 biodiesel program, requiring a 50% blend of biodiesel in all diesel fuel sold domestically. Minister of Energy and Mineral Resources Bahlil Lahadalia announced the program's rollout on Thursday, July 9, 2026, from Karawang, West Java. He asserted that extensive testing across various vehicles, including trains, cars (even Mercedes-Benz), buses, and ships, demonstrated B50's superior performance compared to the previous B40 standard. A key indicator of this improvement, according to Lahadalia, is the enhanced durability of engine filters. While B40 filters typically required replacement after 10,000 to 20,000 kilometers, some vehicles using B50 have reportedly reached 40,000 kilometers without needing a filter change. The program, initiated under President Prabowo Subianto, is a strategic move to decrease reliance on fuel imports, add value to the nation's natural resources, and bolster national energy resilience and sovereignty. The government conducted comprehensive tests involving multiple ministries, agencies, businesses, academics, and industry users to ensure B50's performance, safety, and compatibility across six key sectors: automotive, agriculture, mining, maritime, power generation, and railways. The accelerated development process for B50 was undertaken to meet the 2026 launch target set by President Prabowo. Beyond technical advantages, the B50 program is projected to yield significant economic and environmental benefits. The government anticipates a rise in foreign exchange savings from Rp133.3 trillion (under B40) to approximately Rp170 trillion in 2026. Furthermore, it is expected to boost the value-added of the CPO industry to Rp23.49 trillion, create around 2.1 million jobs, and reduce greenhouse gas emissions by an estimated 44.46 million tons of CO₂.
