Abstract

fetched live from OpenAlex

Le marché des matières récupérées s’est effondré en 2008 et les plastiques ne font pas exception. Leur diversité et leurs incompatibilités réciproques compliquent leur recyclage. Cette étude s’est donné pour objectif d’identifier des façons de donner une valeur ajoutée aux plastiques récupérés par les centres de tri québécois. Dix-neuf recommandations basées sur les 3RV, la faisabilité et la performance ont été formulées à l’égard des différents intervenants du secteur. L’étude a démontré que la valeur ajoutée n’est pas l’unique responsabilité des centres de tri et que plusieurs entités décisionnelles sont interpellées. Une réforme du système de consigne ainsi qu’une réglementation sur la fabrication des produits en plastique et l’uniformisation des matières acceptées par les centres de tri à travers le Québec sont au nombre des recommandations retenues.

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.
