“Torch toilet” is an armchair with built-in toilet, and it is a collaboration amongst three companies who are keen to create a compost toilet that changes people’s perceptions of sanitary objects. The project was originally initiated in order to solve the problem in care homes where one has to have a toilet in the bedroom. Portable toilets often release offensive odours and are aesthetically displeasing.

Using the Acidulo compost decomposition method we have developed, the Torch toilet efficiently decomposes more than 85% of human waste into water and carbon dioxide gas within 24 hours. The remaining substance can be used as high quality compost. The system is waterless and does not require pumping or purification of sewage.

In order for a composting toilet to be accepted in a domestic setting, much sophisticated details that could only be crafted by the highly skilled woodworking manufacturer have been added. The collaboration made it possible to create a compost toilet that is also a beautiful piece of furniture. The Torch toilet will change people’s perception and open up new possibilities for composting products.
