Abstract

fetched live from OpenAlex

Fluorocarbons are tough, unreactive substances. That chemical stability is a big part of why they make such good refrigerants, foam-blowing agents, lubricants, sealants, and nonstick coatings. Once they’re installed, they resist breaking down or reacting with anything. But the air conditioners and other products they are used in do break down, so the fluorocarbons often need to be destroyed. The Montreal Protocol on Substances That Deplete the Ozone Layer and the US Environmental Protection Agency have approved several destruction methods for refrigerants, mostly forms of high-temperature incineration. A company called Midwest Refrigerants owns the only approved conversion method—one that consumes fluorocarbons and yields valuable chemical products. Midwest isn’t an established chemical major, but it isn’t a conventional start-up either. Lew Steinberg and Doug Romine founded Midwest about a decade ago after retiring from careers in import-export and refrigerant reclamation. After seeing that the options for destroying fluorocarbons were expensive and

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
