Manufacturer – ENVIRO OPTIONS Pty Ltd
Country – SOUTH AFRICA
System websitewww.enviro-loo.com/
System Type – Dry – Tank – Continual
Summary – The Enviro Loo is a single unit, waterless toilet system that treats its wastes primarily by dehydration, although slow aerobic composting is part of the treatment process.
The system utilises solar heating of the exposed tank to encourage air flow through the wastes. This also dehydrates the liquid end product, so the tank is a completely sealed unit without the need for liquid end product drains.

The solids drop onto the dehydration plate and slowly move towards the rear extraction area, aided by occasional raking if needed. It is recommended that the dehydrated solids be bagged into an aeration bag and hung near the vent for 6 months for complete treatment.

The Enviro loo has been installed in a number of locations around the world and proven its performance in practical use.
