Included activities starts

The system boundary of the production activity starts from raw material collection.

Included activities ends

The system boundary of production activities ends with biodiesel production.

Description

Biodiesel is a clean fuel that can replace conventional petroleum diesel; the dataset includes primary raw and auxiliary materials, energy inputs, atmospheric emissions, and waste generated during production, but 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 from 2022; the process flow for producing biodiesel from animal fat oils involves steps including oil extraction, impurity removal, transesterification, separation, and post-treatment.

Activity Description

The process flow for producing biodiesel from animal fats and oils includes steps such as oil extraction, impurity removal, transesterification, separation, and post-treatment.

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.
