Abstract

fetched live from OpenAlex

Origin Materials is scaling back operations converting biomass to chemicals as it changes its focus to a completely new business: bottle caps. Origin has developed a technology to treat lignocellulosic feedstock with hydrochloric acid to yield chloromethyl furfural (CMF), which the company has been promoting as a chemical building block to make the polyethylene terephthalate (PET) precursor p -xylene and furandicarboxylic acid, a raw material for polyethylene furanoate. Origin started up a plant with 25,000 metric tons of capacity in Sarnia, Ontario, last year. In addition, though, the company launched a business last year to make PET bottle caps for PET bottles. The aim is to replace the polyethylene and polypropylene caps currently used to make all-PET packages, which are more recyclable. Origin says in a press release that it has lined up a $100 million contract for the caps. But it says that it will reduce its overall staff

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.
