The production activities of this product are based on a weighted average of "1,3-butadiene, two-step process" and "1,3-butadiene, one-step process." If the specific production process for 1,3-butadiene cannot be clearly determined, this dataset can be used. For detailed technical descriptions, system boundaries, and other information, refer to various datasets on 1,3-butadiene production processes. Infrastructure such as equipment manufacturing and facility construction for production is not included within the system boundary of this dataset.
