Here’s an unboxing of a composting toilet by an fellow that’s currently building his own tiny home. The specific unit is an Air Head Composting Toilet – commonly used on boats and RVs.
It’s a simple stand-alone unit that features a clever method for separating liquids from solids, which is done to keep odor down and to promote the composting process. The addition of a ventilation fan also helps the solids dry-out and break-down. This is definitely a step up from a common sawdust toilet.
