Abstract

fetched live from OpenAlex

This thesis introduces WASTED (Waste Analysis Software Tool for Enironmental Decisions). It is a computer-based model that uses life-cycle assessment (LCA) methodology to estimate material flows and environmental impacts of solid waste management. The model consists of a number of separate submodels that describe a typical waste management process. These models are combined to represent a complete waste management system. Based on LCA methodologies, WASTED uses compensatory systems in order to account for the avoided impacts derived from energy recovery and material recycling. In this manner, a comprehensive "cradle-to-grave" analysis of waste management is possible. The purpose of this project is to provide waste managers, environmental researchers and decision makers with a tool that helps them to evaluate waste management plans and to improve the environmental performance of waste management strategies.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
