USA: Composting Toilets: Composting Toilet Manufacturers
ABOUT COMPOSTING TOILETS
Composting toilets are designed for use in places where drainage is not available. Their designs have developed considerably in recent years, with innovations designed to reduce odor, and to make maintenance as easy as possible. Two basic types of composting toilets are available for the private home: self contained units to be placed within the bathroom, and central systems which have a separate processing unit in the basement. Larger centralised systems are available for academic and commercial buildings.

Biolet USA, the US subsidiary of Biolet of Sweden, is a leading manufacturer of composting toilets. Biolet has been a manufacturer of these toilets for 30 years, and claims to be the world's largest. Biolet toilets have advanced liquid controls, and are as easy to use as a flush toilet. They can be installed anywhere, in a few hours, by anyone with basic handyman skills. Under normal operating conditions, Biolet toilets will require emptying every two to twelve months. A constant flow of air into the toilet, and out through a vent pipe to the outdoors, prevents odors.
