Where these two actually differ

  • We flag PLA monomer and oligomer migration, Microplastics generation when heated and Degradation and brittleness over storage 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 PLA (polylactic acid) bioplastic 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 30 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 →
