Abstract

fetched live from OpenAlex

The Canadian chemical maker Nova Chemicals and the packaging firm Novolex plan to build a mechanical polyethylene recycling plant in Connersville, Indiana. The plant will have capacity of about 50,000 metric tons per year and is scheduled to be completed in 2025. Nova will own the plant and market the output. It aims to derive 30% of its polyethylene sales from recycled resins by 2030. Novolex, which has experience in recycling, will operate the facility. It will employ about 125 people.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
