Green Toilet Compact Lux

Average Daily Capacity per 26-Gallon Composting Bin

(Based on approx. 150 uses involving a #2 — i.e., poop) – only the solids count!

👥 Roughly how often will I service a bin?

🟢 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.

🔄 Why two bins?

The Green Toilet Compact Lux comes with two composting bins. The figures above are per bin: when one fills up you swap in the empty one, and the full bin is left to compost undisturbed until you next need it. The second bin doesn’t make the interval longer — it means you never have to empty a bin in a hurry. Additional bins can be added at any time.

⚠️ 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.

CF 8 Composting Toilet – Estimated Daily Capacity

The CF 8 is a continuous composting toilet system featuring a single large 250-gallon container. Like the CF 4, it is designed for gradual emptying rather than batch-style use. Solids are typically removed in thirds or sections, allowing earlier deposits time to fully compost inside the tank.

This setup allows for either:

• Year-round use with gradual emptying, or

• Seasonal use (e.g., 4–5 months/year) with full emptying once per year

🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 8 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container.

Because the CF 8 is more than twice as large as the CF 4, each pile can hold approximately 480–960 poops, depending on composting conditions and how much bulking material is used.

💡 These figures assume that one-third of the tank is in active use at a time, with older waste given time to compost before removal.

🌤 Seasonal Use: Full-Tank Emptying After Inactive Period

For cabins, cottages, or other sites used seasonally, the CF 8 can be used for a few months and then left idle to allow full composting. In such cases, the entire tank may be emptied once a year.

Full-tank capacity estimate: ~1,440–2,880 poops

Example: 120 days of use (approx. 4 months):
→ ~12–24 solid visits per day on average

⚠️ Disclaimer

These numbers are rough estimates based on typical use and conditions. Actual capacity will vary depending on:

• Climate (temperature and humidity)

• Ventilation and air flow

• How much dry bulking material is added

• User behavior and emptying practices

For best performance, ensure proper aeration, regular bulking material use, and consistent emptying of composted portions.

💡 Want to Maximize Capacity? Consider a Urine-Diverting Toilet — With Some Important Considerations

If you’re looking to maximize the capacity of the CF 8 system — aiming for 960+ poops per composting “pile” — we recommend using a urine-diverting (UD) toilet pedestal.

✅ Benefits of Urine Separation:

• Reduces or eliminates the need for dry bulking material, which frees up valuable space in the composting unit

• Helps keep the compost drier, more aerated, and better suited for natural decomposition

• Increases the total capacity of the composting container

• Can lead to faster and more efficient composting, especially in high-use environments

By diverting urine out of the solids container, the volume taken up by absorbent material (like peat or wood shavings) is significantly reduced. This can make a big difference in how often the system needs to be emptied.

⚠️ Downsides to Consider:

Urine-diverting toilets can take some time to get used to. Users need to sit or aim correctly to ensure proper separation, which might not happen consistently without experience or guidance.

For this reason, UD toilets are generally not ideal for public or commercial settings where the toilet is used by guests, tourists, or other first-time users. In these cases, misuse can reduce the effectiveness of the system and may even lead to unpleasant maintenance issues.

In short: A UD toilet is an excellent choice for maximizing capacity in private or family use, but for guest or public access composting toilets, a standard non-diverting model may be more practical and user-friendly.

Green Toilet 100 Easy – Estimated Daily Capacity

The Green Toilet 100 Easy is a compact and user-friendly batch composting toilet with a 26-gallon composting container. Its design makes it well-suited for outhouses, cabins, and even indoor use. A spare container is available to expand capacity and simplify servicing.

🔢 Estimated Solid-Waste Capacity per Bin:

• Bin volume: 26 gallons

• Estimated solid waste capacity: ~200 poops
  (Only includes toilet visits involving pooping – “number two”)

Note: Due to the shape and internal structure of the container, the actual composting capacity is slightly lower than its raw volume might suggest, if you compare with Green Toilet 120 Family composting toilet for example.

📆 Average Daily Capacity per Bin

Notes & Recommendations:

• For seasonal or weekend use, one container often lasts a full summer.

• For more frequent use, we recommend the package with a spare container. This allows one bin to rest and compost while the other is in active use.

• Don’t forget to add dry bulking material (like wood shavings or peat) regularly to maintain airflow and prevent odors.

⚠️ Disclaimer:
These estimates are intended as general guidance. Real-world performance may vary depending on:

• Climate and temperature

• Ventilation quality

• How much dry bulking material is used

• Number of users and usage patterns

CF 4 Composting Toilet – Estimated Daily Capacity

The CF 4 is a continuous composting toilet system featuring a single large 105-gallon container. Unlike batch composting systems (such as the Green Toilet models), the CF 4 is designed for gradual emptying — solids are typically removed in thirds or sections, allowing earlier deposits time to fully compost inside the tank.

This setup allows for either:

• Year-round use with gradual emptying, or

• Seasonal use (e.g. 4–5 months/year) with full emptying once per year

🔁 Continuous Use: Gradual Emptying in Thirds

When used year-round, the CF 4 is typically emptied one-third at a time, effectively composting in three rotating “piles” within the container. Depending on composting conditions and how much bulking material is used, each pile can hold approximately 200–400 poops.

💡 These figures assume that one third of the tank is in active use at a time, with older waste given time to compost before removal.

🌤 Seasonal Use: Full-Tank Emptying After Inactive Period

For cabins, cottages, or other sites used seasonally, the CF 4 can be used for a few months and then left idle to allow full composting. In such cases, the entire tank may be emptied once a year.

• Full-tank capacity estimate: ~600–1,200 poops

• Example: 120 days of use (approx. 4 months):
  → ~5–10 solid visits per day on average

⚠️ Disclaimer

These numbers are rough estimates based on typical use and conditions. Actual capacity will vary depending on:

• Climate (temperature and humidity)

• Ventilation and air flow

• How much dry bulking material is added

• User behavior and emptying practices

For best performance, ensure proper aeration, regular bulking material use, and consistent emptying of composted portions.

Green Toilet 120 Family

💩 Average Daily Capacity per 31-Gallon Composting Bin

🟢 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.

Green Toilet 330

💩 Average Daily Capacity per 87-Gallon Composting Bin

(Based on approx. 1,000 uses involving a #2 — i.e., poop) – only the solids count!

🟢 What counts as a “#2 visit”?
Only visits that involve defecation (pooping) — urine-only visits don’t fill up the composting bin and are not included in the 1,000-use estimate.

⚠️ 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.

💧 Liquid waste (urine) estimate

Average person produces about:

• 0.4 gallons of urine per day
  (≈1.5 liters ≈ 1.6 quarts)

So for 100 people:

• 0.4 gallons × 100 = 40 gallons of urine per day

🚽 Flush water use estimate

Average flush volume in the U.S. is about:

• 1.5 gallons per flush

Average person flushes ~5 times per day, so:

• 1.5 gallons × 5 = 7.5 gallons/person/day

So for 100 people:

• 7.5 gallons × 100 = 750 gallons of flush water per day
