AIRHEAD Waterless Composting Toilet

As 'No Discharge Zones' increase in Australia's lakes and marine national parks, boat owners are restricted from discharging effluent over the side. With existing marine toilet systems, many see the alternative as the installation of holding tanks or messy and odorous chemical toilets.

Holding tanks are hard to retrofit in existing boats that weren't built with space for the tank and macerator. Chemical toilets can only be emptied at designated points or pumpout stations and must NEVER be emptied into the land based composting toilet systems.

Now there is a better way to go! The Airhead composting toilet offers several advantages over the conventional holding tank system. Convenience of use and infrequent and easy disposal of resulting waste, NO ODOUR, no plumbing or through hulls, and no environmental impact.

Composting toilets are not a new idea. They are used in installations found all over Australia where flushing water is not available. Many national parks in Australia have installed land based systems, such as the parks around the Gippsland Lakes in Victoria.

The Airhead is a compact version, designed specifically for boats, caravans, mobile homes etc. The process, once started by adding some core peat, will allow two people to use the toilet for up to 3 months of weekend use, or one month continual use, before needing to be emptied!

Simple to install and sized to fit into existing head areas, the Airhead still offers a standard household size seat.

Remove the existing toilet and close off any through hulls.
Bolt the toilet into place via 2 stainless steel floor brackets. No plumbing required.
Run the flexible ventilation hose to a bulkhead mounted vent, connect to a 12 volt power source (connection to a solar vent is ideal) and your done!

Using the toilet is also simple. Urine is diverted to a forward bottle for seperate emptying. Sold waste is captured in the bowl and send 'south' into the 'composting' tank via a manually operated trap/flap. A paper 'bowl liner' can be used to keep the bowl clean.

Crank the side mounted lever 1/2 turn to incorporate the matter into the core peat and composting is underway! Toilet paper and paper bowl liner all go into the composing tank.

When full, you can empty the tank into a land based composting toilet or put the tank lid on and take the tank home and leave it in the garage. In 3-4 months, you've got fertiliser for the rose garden.

Other options for disposal:
Empty the full tank directly into another composting bin or worm farm.
Empty the full tank into a biodegradable composting bag and bury or add to your garbage bin.

If your use is intermittant, don't be in a hurry to empty the tank. While you are away, the matter is composting and reducing. You'll be surprised how much the volume has reduced when you return.
