The Ekolet® toilet for year-round use composts both toilet and food waste and biologically cleans liquids. It also allows for the use of a hand shower. There is sufficient capacity for continual use by 1–7 people.The bio toilet is made up of a pedestal in the washroom itself plus a rotating, four-compartment composting tank beneath the floor. The electrically assisted air circulation through the ventilation pipe keeps the toilet completely odour-free. The external appearance of the toilet is just like that of an ordinary water toilet. No additives are needed, and no sewerage pipes or water for flushing.When one compartment in the composting tank is full, a thin layer of soil or compost is sprinkled over the top, and a new compartment rotated into position. Depending on amount of use, a new compartment is put into use, and the ready-to-use compost removed, at intervals of about a year. The compost is taken out through a hatch on the side; it is odourless fertilizer that can be spread straight onto plants. The biologically cleansed liquids, can be piped, along with household washing water, into a septic tank, and from there out into nature. In addition to the basic model (YV), we also provide a model equipped with a biological wastewater cleansing system (YV-B) for the most sensitive environment.

The Ekolet is simple and reliable in construction, and can also be used during prolonged power shortages. It contains no parts that could break or become blocked and prevent the use of the toilet. The need for floor space is small due to the vertical design. The Ekolet also effectively reduces the amount of the carcinogenic radon gas by improving the ventilation in the foundations of the house. The material is polythene plastic reinforced by steel and can be recycled.
