General comment The dataset represents the production of polypropylene glycol (3,000da) using a KOH catalyst for the chemical industry. Since on-site data for manufacturing PPG (3,000 da) using a KOH catalyst is inaccessible, literature data were collected for application. The data provided in the literature are values derived from patents and related references of companies producing polyester polyols, such as BASF and Covestro. Using the Gabi software system, the foreground data have been combined with LCI models integrating Ecoinvent 3.9.1. LCI datasets on energy supply systems, ancillary processes, and waste treatment as background data. Therefore, the dataset covers all relevant process steps/technologies over the supply chain of the represented "cradle to gate" inventory with good overall data quality.
An independent expert group in Korea, which is composed by KRICT, has critically reviewed the entire LCI data profile, including data consolidation, development of various LCI models, and the calculation of the associated LCI datasets. |
