Where these two actually differ
- We flag PFAS in cup lining (polyethylene coating), Bisphenol A (BPA) or replacement bisphenols in lining adhesives, Phthalates in plastic coating and Coating degradation and microplastic release with heat on the Starbucks and not on the World Centric.
- We flag Proprietary coating chemical migration, Moisture and microbial growth in fiber matrix, Coating degradation under heat or fatty foods and Recycling contamination if misdisposed on the World Centric and not on the Starbucks.
- The gap is 60 points, wide enough that this is not a close call, and the World Centric is the one to buy.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
