Abstract

fetched live from OpenAlex

The purpose of the paper is to discuss the history of solid waste management (SWM) in. Canada based upon a comprehensive literature review. There has never been a history of SWM in Canada published. Solid waste regulation in Canada is different than in the U.S. The provincial governments establish regulations and policy for solid waste management. Today Canada has about 2600 open landfills and 10,000 closed landfills. Newfoundland Labrador and the northern territories still have some open dumps. In 1993, 70 % of the municipalities had recycling programs. Today Nova Scotia is the leading providence in landfill solid waste diversion. Toronto has a long history in SWM. They started garbage collection in 1834, opened their first incinerator in 1890, and started curbside recycling in 1987. Today they operate two anaerobic digesters to process organic MSW and a clean material recover facility.

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.

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.
