Abstract

fetched live from OpenAlex

The linear waste management model (take-make-dispose) has led to consumption and production patterns that exceed Earth’s sustainable capacity. Zero Waste philosophies emphasize the reduction of raw material usage, retention of value in manufactured products, and align with UNSDG 12 ‘Responsible Consumption and Production’. The University of Calgary’s Zero Waste strategic plan aims to create a Zero Waste campus by 2030. One key challenge is addressing the high volume of non-hazardous lab waste, including unrecycled glass and plastic, discarded lab equipment, and contaminated mixed recycling. Qualitative methodologies, including an electronic survey, are used to create a best-practice guide for implementing sustainable lab activities. Behaviour change barriers related to cost and effort are discussed related to voluntary adoption of environmental behaviour through education, clear communication, commendations, and increased waste diversion options. Staged implementation can potentially offer quantitative metrics to measure future impacts of implementing sustainable lab activities.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
