Enviro Loo Waterless Toilet

The Enviro Loo is a waterless toilet system that provides a safe, non-polluting and cost-effective solution to lack of adequate sanitation facilities. Installed as a permanent structure, the Enviro Loo never requires replacement, relocation or removal.

The Enviro Loo is a "dry or waterless sanitation system". Liquid and solid waste are separated as they enter the container via the toilet bowl. Liquid waste drains to the bottom of the container while solid waste remains on the drying plate. The waste is exposed to continuous airflow that is driven through the unit by the forced aeration ventilation system. The movement of air is assisted by the ventilation extraction unit positioned on top of the outlet vent pipe. As the air moves through the system, it dehydrates the solid waste as it migrates down the sloped drying plate. The liquid that has drained to the bottom of the container evaporates. Sunlight absorbed by the black inspection cover increases the ambient temperature within the container.

The intense heat, prolonged retention periods and oxygen-rich air that is drawn in dehydrate and decompose the waste. At the end of this process the waste is converted via the stimulated bacterial and biological activity into an inoffensive, stabilized material which is reduced to roughly 5% of its original volume. The negative pressure within the container prevents the escape of any odor through the toilet bowl or the air inlet pipes.

Currently, there are four Enviro Loo models available with the same standard of materials and principles. The differences reside in capacity and unit specifications. The solutions are catered to domestic, communal and industrial uses. The prices of the systems vary from $600 USD.
