# Homogeneous Catalytic PET Depolymerisation Dataset

Experimental data on homogeneous catalytic PET depolymerisation is scattered across prose, tables and supporting information, and manual consolidation does not scale. This pipeline has an extractor tag each record with the unique identifiers of its source text chunks, then an independent LLM judge reads the full paper, checks each field and proposes cited corrections. On 295 hand-curated ionic-liquid PET glycolysis experiments the judge agreed with human evaluation on 85.7% of reviewed records; across 3,942 records from 561 papers it accepted 67.5% as written, with corrections concentrated in quantitative fields such as catalyst and solvent mass.
