Airhead Composting Toilet

The Airhead Composting Toilet works simply. By separating liquids from solids, the volume of solid human matter is significantly reduced. Air Head’s approximate five-gallon capacity means that up to a season’s worth of weekend use may be held. (Based on solid matter volume for two persons’ use twice every weekend for five months: 80 uses). A liveaboard couple can expect 60 uses (one month) before they’ll have to empty the solids tank.

Much like a household toilet the Airhead Composting Toilet has a bowl and an actuator which provides a “flush.” The main difference is the “Air Head” Holding Toilet’s waterless operation. A paper bowl liner acts as a carrier for solid matter on its way to the solids tank.

The solid matter is separated and agitated, thereby decomposing it into a non-offensive state inside the large tank. Additionally, the unit has an integral 12-volt fan that provides a constant negative pressure to pull moisture out of the living space. Even after long lay-ups, there is no “holding tank” smell when you come aboard.

In the Airhead Composting Toilet Liquids are collected in the smaller forward tank. Its wide-mouthed aperture will keep the contents emptying smoothly into any standard commode. The liquid tank will hold approximately four days use per person if used exclusively. A low-profile bottle is also available that holds about half the volume of the standard bottle.
