How Composting Toilets Work & Why Airhead is the Best Choice

Composting toilets offer an eco-friendly, low-maintenance alternative to traditional marine toilets, making them ideal for boats, RVs, and off-grid cabins. Unlike conventional systems that require plumbing and pump-outs, composting toilets use natural processes to break down waste efficiently—no chemicals or water needed!

How Do Composting Toilets Work?

Composting toilets function by separating liquid and solid waste to reduce odor and facilitate natural decomposition. Here’s a breakdown of the process:

• Separation of Waste – Liquids are diverted into a sealed container, while solids mix with a composting medium (like coconut coir or peat moss) to promote aerobic decomposition.
• Aeration & Ventilation – A small fan pulls air through the system, keeping the compost dry and eliminating odors.
• Evaporation & Decomposition – Liquids evaporate, and solids break down over time, turning into compost-like material that can be safely disposed of.

Mounting & Installation

Installing a composting toilet in a campervan or boat requires a secure and well-ventilated setup to ensure stability and odor-free operation. Airhead Composting Toilets are designed for easy installation in both environments:

For Campervan Conversions:

• Compact & Space-Saving – Fits in tight van layouts without requiring a black water tank.
• Simple Ventilation – A vent hose can be routed through the floor, wall, or ceiling using a small fan to remove moisture and odors.
• Secure Mounting – The toilet can be bolted to the van floor to keep it stable while driving.

For Marine Installation:

• Stable & Rugged Design – Built to withstand movement and rough waters.
• Bulkhead or Deck Venting – The vent hose can be directed outside through a hull fitting or deck fitting.
• No Plumbing Required – Eliminates the need for complex marine head plumbing and holding tanks, saving space and reducing maintenance.

With easy installation and no need for external plumbing or tank connections, Airhead Composting Toilets are the perfect solution for off-grid vanlifers and boaters alike.

Waste Disposal

One of the biggest advantages of a composting toilet is the extended time between emptying. Here’s how disposal works:

• Liquids – The urine bottle should be emptied every 2-3 days, depending on usage. It can be disposed of in a regular toilet or designated area.
• Solids – With regular use, the solids container can last several weeks before needing disposal. Once full, the material can be bagged and disposed of in a composting facility, regular trash (if fully decomposed), or buried in accordance with local regulations.

Cleaning & Maintenance

Composting toilets require minimal upkeep compared to traditional marine heads. Here’s what’s needed:

• Routine Emptying – Regularly emptying the urine container prevents overflow and odors.
• Occasional Stirring – Mixing the solids after each use ensures even decomposition.
• Ventilation Check – Ensuring the fan and vent system remain clear for proper airflow.
• Wipe Down Surfaces – A quick wipe with a mild, biodegradable cleaner keeps the toilet fresh and hygienic.
