A dry separation toilet consists of a body, a lid and a toilet seat. Its inner parts include two containers and a urine separator. This separates liquid from solid and thus forms the heart of the toilet. The aim is to keep the big business as dry as possible.

For this purpose, the urine is diverted to the front into a canister. To prevent leakage and odors, the lid of the canister has a special membrane. The solid waste ends up in a separate container lined with a garbage bag. Here you can also throw the toilet paper.

To enhance the drying process, sprinkle the big business with bedding material after going to the toilet. Drying prevents the formation of bacteria, which are responsible for the usual odor. For emptying, you can remove both containers separately from each other.

Odors occur when solid and liquid waste mix. By separating the waste and then drying the solids, unpleasant smells can be minimized.

Suitable types of litter include: sawdust, small animal bedding, Terra Preta, coconut coir bricks, litter with activated charcoal, soil, and coffee grounds.

Urine can easily be disposed of via the regular wastewater system or used diluted as fertilizer. Solid waste belongs in the residual waste bin, though composting may be possible under certain conditions.

Cleaning a composting toilet is simple and can be done effectively using mild household agents such as diluted citric acid or vinegar. pH-neutral cleaners or those with effective microorganisms are also suitable. Harsh chemicals and abrasive tools should be avoided, as they can damage the material.
