The necessary accessories of a composting toilet are, despite the different models, essentially the same. An indispensable component of all model designs is the litter to bind the emerging moisture of the excretions and to prevent odours. Models with an electric exhaust system or other electrical devices, such as stirring units, etc., also need a respective connection. The disposal of the excretions is different depending on the model. Composting toilets without built-in composters rely on an external composting facility into which the collected waste including litter can be emptied. For composting that is as efficient as possible, a closed fast composter is recommended. However, a conventional compost pile is also suitable. For this, the excretions should be allowed to rest for at least 24 months to ensure that it is completely composted – you can still add other biological waste from the garden and kitchen, though. Finally, to avoid any washing out by rainwater, a cover in the form of a tarpaulin or the like is recommended. In the case of models with an integrated composter, the finished compost can be taken directly from the toilet – after a rest period of at least two years – and used to fertilise ornamental areas, flowers, trees and shrubs. Finally, the cleaning of a composting toilet differs only slightly from that of a conventional toilet. Thanks to the waterless operation, toilet brushes and cleaning agents are not required at any time. Externally, not much more cleaning is needed as in the case of regular toilets either as these differ only slightly in appearance and use and the cleaning effort is generally limited to wiping the seating surface with a damp cloth. Finally, the cleaning of the composter is unnecessary because of its function as decomposition and fermentation equipment.
