Description
Free fatty acids are one of the substances produced by the decomposition of neutral fat; this dataset includes major raw and auxiliary materials, energy, atmospheric emissions, and waste from the production process, but infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset; the life cycle inventory data were sourced from literature and optimized based on the best available information from 2022; the process flow for producing biodiesel from waste edible oil collection, treatment, and processing includes filtration and pretreatment, esterification, neutralization, separation, decolorization and purification, water and acid removal, distillation, and refining; among these steps, impurities and water in the oil are separated by heating followed by sedimentation. Acid is a co-product of this process.
Activity Description
The process flow for producing biodiesel from the collection, treatment, and processing of waste cooking oil includes filtration and pretreatment, esterification, neutralization, separation, decolorization and purification, dehydration and deacidification, distillation, and refining. In this process, impurities and water in the oil are separated by heating followed by sedimentation, and free fatty acids are generated as a co-product.
Process Description
Fatty acids are a class of compounds composed of carbon, hydrogen, and oxygen, and are the main components of neutral fats, phospholipids, and glycolipids. Free fatty acids (FFA) are a type of organic acid. Lipids present in the human body can be broadly classified into three types: cholesterol, neutral fats (triglycerides), and phospholipids. Free fatty acids are one of the substances produced by the breakdown of neutral fats.
