Performance of geosynthetics in methane oxidation systems
Bibliographic record
Abstract
Landfills are a major source of methane emissions contributing to climate change. These emissions can be fugitive emissions from capped landfills, where hotspots form due to vulnerabilities (e.g., holes, fissures) in the cover. A research project investigating the use of “biowindows” for the biological oxidation of methane has been initiated by the Université de Sherbrooke. This study will examine the performance of geosynthetic drainage composite as a gas distribution layer (GDL) and a wicking geotextile as a separation layer between the methane oxidation layer and GDL. This study is a pilot scale installation with ten 2 m x 2 m biowindows fed directly by landfill gas. As occlusion due to moisture retention is a major impediment to gas transport and system efficiency, this study examines the inclusion of geosynthetics and their effects on gas transport and system efficiency.

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.
