The convenience of using the wc - the environmental friendliness of the composting toilet.
In AQ Biokäymälä, a toilet seat is used for flushing and transporting waste. The separator unit placed on top of the composting space separates liquids and solids from each other, solids to the composting unit (excrement, papers) and liquids (urine, rinsing water) to the waste water either directly (normal areas) or through the NP nutrient removal unit (coastal and groundwater areas). Another option is to separate the nutrient-rich urine and use it as fertilizer on your own property.
