B50 Transition Not as Smooth as Anticipated, Key Challenges Identified

Jakarta, VIVA – The government continues to promote biodiesel development as part of the national energy transition strategy. Following the implementation of B40 in several sectors, B50 usage is being prepared to support reduced dependence on fossil fuels while strengthening domestic palm oil-based energy. Conversely, higher biodiesel concentrations in fuel blends present new technical challenges for diesel-dependent industries such as mining, plantations, construction, and transport. Industry players have highlighted potential fuel system disruptions due to the characteristics of biodiesel with higher FAME content. Local filter manufacturer Bpfilters has introduced a new line of diesel filters designed for diesel engines and heavy machinery using B50 fuel. The product launch is scheduled in Bogor in June 2026. The company stated that implementing B50, a 50% FAME/B100 blend, poses different challenges compared to B40. Higher FAME content is hygroscopic, absorbs moisture more readily, oxidises faster, and can cause sludge formation and microbial growth in fuel tanks. ‘Bpfilters has innovated to anticipate potential issues such as clogged filters, blocked injectors, and reduced heavy machinery productivity,’ said Bonny Pratama, Managing Director of Bpfilters Indonesia, as quoted in a press release on Monday, 25 May 2026. Bpfilters’ B50 filtration products were developed using three design approaches: increased filtration area, multi-stage water separation, and advanced micron rating media. The company claims the technology extends filter lifespan, maintains stable engine performance, and improves fuel efficiency through cleaner combustion. Bpfilters also reported that products used by consumers on B40 showed improved filter longevity compared to conventional filters. In trucks and buses, diesel filters previously clogging at 5,000 kilometres now last up to 20,000 kilometres with Bpfilters’ products. For heavy machinery, filter usage life has been extended from 250 operational hours to 1,000 hours.
