A life cycle analysis and impact assessment on styrofoam collected through the Reduction and Recycling Pilot Program
Bibliographic record
Abstract
Focusing on the User and Disposal Phases, this report assessed the life cycle impact of Styrofoam waste collected through the UBC Vancouver Styrofoam Reduction and Recycling Pilot Program. In the User Phase, participating buildings had different experiences with various vendors, including seeing the companies’ improvements in package reduction and positive reactions to campaigning efforts. In the Disposal Phase, three current cases of waste management for Styrofoam are assessed and compared in terms of the economics, environment, and social impacts. Recycling is a three-staged process: collected Styrofoam materials from UBC are first shipped to WCS Recycling to be made into #6 pellets, which are then sent to Merlin Plastics for purification and further processing. The resultant Polystyrene #6 pellets will be shipped to an injection-molding company which produces virgin-blended recycled plastic products that are sold internationally. Re-use is the case for UBC Okanagan, as a partnership with Turtle Tanks was developed to incorporate Styrofoam waste into household septic systems. Landfill is a last and most inefficient option. Three alternatives are discussed in this report: 1. Expansion of the current recycling program; 2. Reduction from the source by working with vendors; 3. Explore partnership for re-using Styrofoam boxes; 4. Incineration. Each of these alternatives is evaluated upon four criteria of feasibility, environmental impact, cost, and sustainability of initiative. The alternatives are not exclusive from each other and could be implemented in an integrative fashion. The report concludes with several suggested areas for further research.

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.
