Where these two actually differ
- We flag PFAS in grease-resistant coating, Unidentified synthetic coating leachables, Coating degradation over time and Compostability misrepresentation risk on the World Centric 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 World Centric.
- The World Centric is Fiber-based tray with grease/moisture-resistant coating (composition unspecified) where the World Centric is Fiber-based (wood pulp/molded fiber), compostable coating, which is most of the difference in these two grades.
- The gap is 75 points, wide enough that this is not a close call, and the World Centric is the one to buy.
- We are less certain about the World Centric grade, at 42% confidence against 78%, because it discloses less.
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 →
