Abstract
In the 11th grade, when most people are thinking about college, Miranda Wang and Jeanny Yao had plastic on their minds. During an environmental-club field trip in 2011, the two visited a waste transfer station in Vancouver, British Columbia, and had a life-changing experience. “We were shocked to see how much plastic was in the garbage” and that it wasn’t being recycled, Wang says. The trip set the women on a life course. Wang and Yao saw a need for some new kind of technology to process plastics, Wang says. So they built one. In 2015, they founded BioCellection, a Menlo Park, California, start-up focused on breaking down polyethylene waste and changing it into a usable commodity. The company is focusing on polyethylene, Wang and Yao say, because recycling technology for the popular plastics poly(ethylene terephthalate) and polystyrene already exists, but there’s a hole in the recycling landscape where polyethylene

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
