Where these two actually differ
- We flag Leachables from undisclosed grease-resistant coating, Thermal degradation and microplastic potential if overheated and Incomplete composting in non-industrial environments on the Eco-Products and not on the Solo.
- We flag Styrene monomer leaching, Microplastics from degradation, Lid seal integrity and bacterial growth and Acetone or solvent sensitivity on the Solo and not on the Eco-Products.
- The Eco-Products is Plant-based compostable PLA coating where the Solo is Polystyrene (PS) cup, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
- We are less certain about the Solo grade, at 45% confidence against 78%, 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 →
