Abstract

fetched live from OpenAlex

RWDC Industries, a maker of the biodegradable polymer polyhydroxyalkanoate (PHA), has raised $95 million in series B funding, bringing its total financing to $208 million. The company will use the money to expand capacity at its Athens, Georgia, plant to 50,000 metric tons (t) per year. It also plans a facility in Singapore. RWDC finished a 5,000 t plant in Athens earlier this year and has begun building a 25,000 t unit set for completion in 2023. Separately, Danimer Scientific says it expects to break ground this quarter for a PHA plant in Bainbridge, Georgia. It will have capacity of about 110,000 t when completed in 2024.

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.
