🟢 What counts as a “#2 visit”?
Only visits that involve pooping (i.e., going number two) — urine-only visits don’t contribute to filling the composting bin and are not included in the estimate.
⚠️ Disclaimer:
These estimates are approximations. The actual number of solid uses per bin may vary significantly depending on climate, temperature, ventilation, user habits, and the amount of dry bulking material (e.g., wood shavings or peat) added after each use.

⚠️ Disclaimer:
These estimates are based on typical, steady use. The actual number of solid uses a composting bin can handle may vary significantly depending on climate, temperature, humidity, ventilation, and how much dry bulking material (like wood shavings) is added after each use.
