General comment The dataset represents the production of polypropylene glycol (PPG) (3,000da) using a DMC catalyst for the chemical industry. Since on-site data for manufacturing PPG (3,000 da) using a DMC catalyst is inaccessible, literature data were collected for application. The data provided in the literature are values designed based on patents and related references from companies producing polyester polyols such as BASF and Covestro. Using the Gabi software system, the foreground data have been combined with LCI models integrating the Ecoinvent 3.9.1 LCI dataset on energy supply systems, ancillary processes, and waste treatment as background data. Therefore, the data set covers all relevant process steps/ technologies over the supply chain of the represented "cradle to gate" inventory with a 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. |
