Where these two actually differ

  • We flag Water and grease-resistant coating composition (non-PFAS), Ink or adhesive off-gassing and migration and Degradation and fragmentation during storage or composting on the Footprint (EarthBox line) 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 Footprint (EarthBox line).
  • The Footprint (EarthBox line) is Kraft paper with unspecified water/grease-resistant coating 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 Footprint (EarthBox line) 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 →
