A Practical Guide for When Nature... Clogs.
The Art of Composting
Your composting toilet is a wonderfully simple machine. When an issue pops up, it’s not broken—it’s a sign that the tiny ecosystem inside is a little off-balance. Think of yourself less as a plumber and more as a gardener for a microscopic workforce. Here are the four key ingredients they need to thrive.
Fresh Air is Key - Ventilation
- For odour-free operation (the secret to a happy cabin)
- Gives your microbes the oxygen they need to break things down
- Helps evaporate excess liquid, preventing sogginess
- Ensures flying pests don't make a home in your throne
The Right Amount of Damp - Moisture
- Allows excess liquid (leachate) to drain away properly
- Prevents the dreaded "compost swamp" from forming in the base
- Manages moisture, especially after a weekend with lots of guests
- The goal: your compost should feel like a damp, wrung-out sponge
The "Brown Gold" - Carbon
- This is your secret weapon: wood shavings or peat moss
- Balances the nitrogen-rich material from users
- Creates essential air pockets for healthy decomposition
- Absorbs extra moisture and is key to preventing odours
The "Green" Ingredient - Waste
- Provides the essential nitrogen that fuels the entire process
- Introduces the necessary bacteria to get things started
- Urine adds more nitrogen and critical moisture
- Don't be shy; your "contributions" are what make the magic happen!
Why is the compost chamber filling up quickly?
If your compost is piling high, the natural breakdown process has likely stalled. Let's investigate the usual suspects:
Too Much Liquid
- Blocked Drain: Solids may have created a tiny dam. Time for a quick check (see your manual for specifics).
- Fan or Vent Issue: Ensure the fan is running and the vent pipe is clear of leaves, debris, or nesting critters.
High Traffic
- Was it a long weekend with the whole family? Heavy use can fill the drum faster than it can compost. Give it a few days; it will catch up.
Why is the composting process so slow?
If the pile looks the same as it did last week, it just needs a little encouragement to get going again.
Add More Carbon
- This is the #1 fix. A scoop of wood shavings after every few uses soaks up excess liquid and fluffs up the pile, letting air in.
Too Cold
- Compost microbes are fair-weather workers. If the unit is in a cold spot, try insulating the tank. For heated models, ensure the heater is on and set correctly.
How do I get rid of flies?
Flies or gnats are a sure sign the compost surface has become too dry, which is an open invitation for them to move in.
First, stir about a cup of water into the top layer of the pile. To break the life cycle of any existing pests, you can use a pyrethrum-based insect spray daily for a week. Always finish by adding a fresh, clean layer of wood shavings on top to discourage new visitors.
