Abstract
The rapid accumulation of municipal solid waste is of significant environmental concern. Anaerobic digestion (AD) is a promising solution for stabilising the organic fraction of municipal solid waste (OFMSW). The study characterises the effects of alkaline pretreatment of simulated-organic fraction of municipal solid waste (S-OFMSW) using sodium hydroxide (NaOH) and potassium hydroxide (KOH) at four pH values of 10, 11, 12 and 13 and two temperatures of 23±1°C and 80±1°C. Pretreatment at pH 13 and 80±1°C demonstrated the maximum S-OFMSW solubility for both NaOH and KOH. However, biogas production from BMP assays for both pretreatment chemicals demonstrated the greatest biogas yields relative to removed volatile solids (VS) at pH 12 and 23±1°C. Semi-continuous reactor experiments of S-OFMSW pretreated with NaOH and KOH at pH 12 and 23±1°C at SRTs of 10, 15, and 20 days demonstrated that pretreatment significantly improves the AD performance at SRTs of 10 and 15 days.

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
