Description
Biodiesel is a clean fuel that can replace conventional petroleum diesel. This dataset includes primary raw materials, auxiliary materials, energy inputs, and atmospheric emissions from the production process; however, infrastructure such as production equipment and facility construction is not included within the system boundary. The life cycle inventory data are sourced from literature and have been optimized based on the best available information for 2022. The technological process for producing biodiesel from collected waste edible oil involves steps such as filtration and pretreatment, esterification, neutralization, separation, decolorization and purification, dehydration and acid removal, distillation, and refining. Impurities and water in the oil are separated through a process of heating followed by sedimentation.
Activity Description
The production process of biodiesel from waste edible oil collection, treatment, and processing includes filtration and pretreatment, esterification reaction, neutralization, separation, decolorization and purification, dehydration and acid removal, distillation, and refining. Among these, impurities and water in the oil are separated by heating followed by sedimentation.
Process Description
Biodiesel refers to fatty acid methyl or ethyl esters produced through transesterification of vegetable oils, animal fats, waste oils, or microbial oils with methanol or ethanol. Biodiesel is a clean fuel that can replace conventional petroleum diesel.
