Abstract

fetched live from OpenAlex

Bioreactor landfills are operated for rapid stabilization of waste, increased landfill gas generation for cost-effective energy recovery, increase in landfill space, enhanced leachate treatment, and reduced post closure maintenance period. Due to rapid stabilization and settlement of solid waste, bioreactor landfills are gaining popularity as an alternative to conventional Subtitle D landfills. However, the addition of leachate to accelerate waste decomposition changes the physical and engineering characteristics of Municipal Solid Waste (MSW), which affects the compressibility and shear strength behavior of MSW. Settlement during the active landfilling period is beneficial as it increases the landfill capacity, however, large differential settlement may cause serious damage to the existing leachate recirculation pipe system and interim covers. Also, due to accelerated decomposition and changes in shear strength properties, the stability of landfill slopes is expected to be affected. The objective of this paper is to analyze the compressibility of MSW in a bioreactor landfill as a function of construction sequence, time and waste placement using the finite element program PLAXIS. In this analysis, the layer properties are adjusted to account for extent of decomposition. The results from PLAXIS are compared with waste settlement data collected during the filling of a landfill cell at Calgary Biocell in Canada.

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.
