Why compost toilets ?

A compost toilet provides a complete circulation of nutritious substances. The fertilization of streams, lakes och seas will be reduced.
There is no use of fresh water. It is important especially in areas with lack of water.

How does it work ?

In a compost bin the waste from toilet and kitchen will, together with a supply of air, be broken down to compost. The heat generated by the decomposition will cause fluid to vapourise. The vapour is then evacuated through a ventilation pipe. The vaste will be drastically reduced in volume and be emptied normally every second year.


10-40 litres compost per person and year, which can be used to improve the soil.
