Using a Bionova differs little from using a conventional toilet. The sitting position is identical to that of a regular toilet – this applies to both men and women. Thanks to the contact-free separation system the body only touches the toilet seat. Merely urinating while standing should be avoided as the urine cannot be fully separated in this case.

Since unpleasant odours only develop when faeces come into contact with urine, the Bionova separation system prevents a mixing of the excretions. Remaining odours and any arising moisture are also absorbed by litter which is not required in a Bionova with an electric exhaust system.

By separating the excretions, odours are reduced to a minimum and the subsequent disposal of toilet waste is made easier. Unpleasant odours arise only when urine and faeces are combined which is why it is possible to do without toilet chemicals that are harmful to the environment.
