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 .
- We flag Undisclosed waterproofing chemicals (possible PFAS or fluorinated compounds), Microplastics from coating degradation and Composting claim unverified on the and not on the Matter.
- The Matter is Plant-based fiber pulp (compostable) where the is Compostable resin/plastic with waterproofing (type 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 grade, at 35% confidence against 82%, because it discloses less.
