Abstract


Background/Objectives: Efficient management of organic waste is necessary to avoid negative impacts on the environment and highly potential to be converted into biofuel. The objective of this study was to conduct preliminary analysis of organic wastes that used for biofuel production and characterization of bio-liquids produced. Methods/Statistical Analysis: Cow dung, pineapple peel, vegetable waste, fish waste and leftover chicken were used in production of methanol from methane system using anaerobic co-digestion method conducted at room temperature, pH 6.4-7.0 for 19 and 30 days in 500 mL of bio-reactor. Gas Chromatography Thermal Conductively Detector (GC-TCD) was used in determination of methane while bio-alcohol formed was detected by High Performance Liquid Chromatography (HPLC). Findings: Co-digestion of R2 (cow dung mixed pineapple skin) produced highest methane (23.07% wt), bio-methanol (19.08 g/L), bio-ethanol (51.30g/L) and glucose (35g/L). This study proved that co-digestion of organic wastes able to produce biogas and bio-alcohol better than digestion of only one substrate. Application/Improvements: The upgrading stage of bio-liquid produced is required to optimize the yield of the bio-liquid and increasing the productivity in large scale study so that it will be qualified for biofuel application.
