Executive summary + methods
A small set of current alternatives meaningfully reduce landfill contribution and chemical exposure versus conventional disposables according to the available evidence: hybrid/reusable systems built around reusable waterproof shells and cloth inserts, compostable or biobased disposable systems with industrial take-back, and higher-transparency reduced-chemistry disposables.
The scoring rubric ranks GroVia hybrid highest overall, followed by Dyper, Eco by Naty / Kudos, Moltex, and Bambo Nature. Key constraints include limited industrial composting access, uneven independent chemical testing across brands, and variable on-bench performance among eco-branded disposables.
Scoring rubric
Criteria are weighted to balance household value, environmental impact, chemical safety, performance, end-of-life feasibility, and corporate governance. Scores run from 0–100 per criterion, and the weighted sum yields the overall score.
| Criterion | Weight | What it captures |
|---|---|---|
| Cost-to-quality ratio | 20 | Price relative to durability, absorbency, convenience, and overall value. |
| Environmental impact | 25 | Lifecycle impact, degradability, fossil-plastic content, and SAP content. |
| Chemical safety and transparency | 20 | Ingredient disclosure, chemical limits, certifications, and independent testing. |
| Performance | 15 | Absorbency, leakage prevention, fit, ease of use, and skin outcomes. |
| Practical end-of-life support | 10 | Take-back, composting, recycling, and local infrastructure availability. |
| Corporate and ethical sourcing/governance | 10 | Supply-chain credibility, certifications, governance transparency, and labor evidence. |
