Sugarcane filter cake is a by-product from clarification step in sugar production process. Policosanol, a high value added compound is naturally presented in sugarcane wax. To improve value creation of sugarcane filter cake, policosanol was extracted from filter cake in a form of crude wax. The more environmental friendly extraction methods, accelerated solvent extraction (ASE) and supercritical fluid extraction (SFE) were studied to extract crude wax from filter cake in comparison with Soxhlet extraction. The result showed that ASE and SFE with co-solvent could separate wax from dried filter cake with % yield of 13.32% and 5.46% while Soxhlet extraction gave 9.03%. Chemical characterization from FT-IR and TLC-FID indicated a similarity in composition and it was not different from the wax extracted directly from sugarcane stem K84-200 a Thai commercial sugarcane variety. Thermal characteristic of crude wax was also analyzed by differential scanning calorimetry (DSC).
