Urine divertion and dry composting of fecal matter at
Tingvall conference center Sweden
Single flush urine diverting toilets are used. The faeces are
collected dry and approx.0,2l of water is is used to flush
the urine. The composting chamber has a slight
underpressure so that air flow is down through the toilet
bowl, thus, there is no foul odour in the toilet room.
