The Mobile Rota-Loo

The Mobile Rota-Loo was designed in response to the clearly identified need for an environmentally friendly transportable sanitation system.

The Mobile Rota-Loo combines the concepts and passive design technology of the Soltran Building™, the Rota-Loo composting toilet system, excess liquid evaporation tanks with a robust trailer mechanism. In doing so “we have achieved a more efficient and simplified composting system which can be conveniently towed anywhere a vehicle can go”.


The Mobile Rota-Loo evolved from a request by one of Australia’s largest wine growing companies to help them solve the problem of providing decent sanitation for their workers in the fields. The only systems previously available were chemical toilets, which invariably smelt and caused problems when they needed to be relocated or emptied.
