Summary – The Classic 50 is a batch composting system that is suited for 2 persons part time such as i a cabin or locations where occasional use occurs.
Being a batch system, the tank is removed when full and left to compost and a new tank placed under the toilet pedestal.

As with all batch systems, it requires clearance under the house for the tank as well as an exit area to slide the tank along the floor and a storage area for the used tank or tanks. An advantage to the batch system is that extra tanks can be added to extend the capacity.
The container and chute are made from low density polyethylene and contain breathing pipes and a filter floor to allow the liquid end product to drain to an outside soakaway. The breathing pipes are part of the 12 volt ventilation system that is supplied with a transformer if you are connected to the mains. A variety of pedestals is available with the system.

With a long track record of use in Australia, the Nature loo systems have proved to be reliable and easy to use where there is space to place the system under the toilet room.
