Abstract
Three laboratory-scale bioreactors were used to investigate the influence of bioavailable carbon addition on the composting process of tomato remains. Sugar, cheese whey and used cooking oil were used as bioavailable carbon sources. The amounts of materials added to the compost mixture had equal energy contents. The initial moisture contents and C: N ratios of the compost mixtures were maintained at 60 % and 30: 1, respectively. The average bioreactor temperature was strongly influenced by the type of bioavailable carbon. The maximum bioreactor temperature was 50.8, 56.9, 63.4 and 63.3 ºC for the control and the mixtures receiving sugar, cheese whey and used cooking oil, respectively. Strong correlations were observed between the maximum temperature achieved (and its duration) and the reductions in fat and volatile solids contents. The total fat reductions were in the range of 64.6-88.8 %, whereas the total carbohydrates reductions were in the range of 21.5-31.7 %. Reductions of 12.4-25.3 % and 3.5-17.7 % were also achieved in protein content and TKN. Neither the nitrogen nor the moisture contents were limiting factors. The ammonium nitrogen remained unchanged at 0.33-0.35 % and the moisture content remained at 59.7 ±0.61 %.

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 it
