Where these two actually differ

  • We flag Microbe/mold growth if stored damp and Cellulose degradation under repeated hot/wet stress on the Matter and not on the Paper Mart.
  • We flag PFAS in grease-resistant coating, Microplastic or fiber migration when heated or damaged, Coating leachables (unidentified composition) and Insufficient degradation in non-industrial settings on the Paper Mart and not on the Matter.
  • The Matter is Plant-based fiber pulp (compostable) where the Paper Mart is Compostable fiber/pulp with grease-resistant coating (unspecified), 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 Matter is the one to buy.
  • We are less certain about the Paper Mart grade, at 35% confidence against 82%, because it discloses less.

Both products run through the same public rubric, which covers 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 →
