Composting latrine

In this latrine, excreta fall into a watertight tank to which ash or vegetable matter is added. If the moisture content and chemical balance are controlled, the mixture will decompose to form a good soil conditioner in about four months. Pathogens are killed in the dry alkaline compost, which can be removed for application to the land as a fertilizer. There are two types of composting latrine: in one, compost is produced continuously, and in the other, two containers are used to produce it in batches.



A valuable humus is produced

Careful operation is essential


Urine has to be collected separately in the batch system


Ash or vegetable matter must be added regularly
