Driven by both energy saving and emission reduction as well as energy security, many countries around the world actively promote biodiesel to replace traditional diesel. For example, in Southeast Asia, Indonesia has made increasing the biodiesel blending ratio a key focus of its national energy and industrial policy: phased implementation began in 2008, gradually increasing from low ratios (such as B2, B5); by 2020 it had promoted B30, by 1 January 2025 B40, and by 2026 plans to reach B50, with tests on B100 applications conducted on some power generation equipment.

High blending ratios (≥B20), while beneficial for energy self-sufficiency, also bring a series of technical challenges, including poor cold flow properties, mono-glyceride precipitation, filter blockage, material compatibility issues, and difficulty in water removal due to decreased interfacial tension, leading to engine injection system corrosion/damage, reduced equipment operational rates, and significantly increased maintenance and repair costs. To keep projects on schedule, additional equipment procurement is often required, further increasing capital expenditure.

For domestic OEMs actively expanding overseas and seeking to develop the biodiesel market, it is crucial to establish a stable and reliable engine fuel filtration solution when facing such stringent conditions in the Indonesian market. For the application of high-blend biodiesel (especially Indonesia palm-based FAME), correctly selecting and effectively maintaining dedicated biodiesel filters is key to ensuring the long-term stable operation of engines and equipment.
