Theory and Practice in Plastic Recycling in the Selected European Union Member Countries and in Canada from 1999 to the Present
Bibliographic record
Abstract
The aim of the presented thesis is to briefly introduce the problems connected with waste in general and with the trends in its disposal with specific attention being paid to PE, PP, PS, PVC and PET. The author approaches the topic from economical and ecological points of view and offers an insight into the waste management in three chosen countries. For the purpose of this bachelor thesis, there are chosen the following states: the Czech Republic, the Great Britain and Canada. In order to get a broader view of the subject, the European Union policy is studied. Reprocessed plastics and final products used in various applications are described. The advantages of responsible waste management, namely of plastic recycling, are accentuated throughout this work.

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.
