Abstract
In this thesis, a study was undertaken on the premise that the world population living in urban centers is expected to increase from 3.8 billion to 5.2 billion, from 2005 to 2025, representing 54% and 65% of total world population, respectively. The urban population (UP) growth will produce remarkable amounts of urban food waste (UFW) that will add more pressure on already overloaded municipal solid waste (MSW) management systems of cities. This problem is more serious in countries experiencing major economic growth such as China where UP is expected to increase from 44% to 66% of the total country population, from 1995 to 2025. Asia produces the largest amount of UFW, which is expected to increase from 251 million ton to 418 million ton (45% to 53% of total world UFW) from 1995 to 2025. On site treatment of UFW along with a limited movement of world population from rural to urban areas are suggested to reduce pressure on MS W management system for the upcoming decades. In this thesis, a project was also undertaken to develop compost recipes for urban center such as downtown Montreal. Monthly (June to August) average residential FW production was found to 0.61 (+/-0.13) kg capita-1 day-1 and that of a restaurant was found to be 0.56 (+/-0.23) kg customer-1 day-1. From trial tests, the best compost recipes mixed 8.9 kg, 8.6 kg and 7.8 kg of UFW for every kg of wheat straw, hay and wood shaving, on a wet mass basis. However, quantity and characteristics of FW vary from one month to another; therefore, regular adjustment of compost recipe is recommended. When using wood shavings as bulking agent, it is strongly recommended to correct the acid pH.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
