Liquid portable toilets

 

— these types of toilets use special chemicals that process waste, break down solids and eliminate odours. Such toilets can be used both on the street and in the house (although it is still impossible to completely eliminate the smell, so it is advisable to install such a device away from the kitchen); they are completely autonomous, do not require electricity, ventilation or drainage systems. Among the shortcomings, it can be noted that the collected waste cannot be simply poured directly into the soil — due to the presence of chemicals, they can harm the environment. In addition, for such a toilet, you will have to periodically buy additional reagents, which is associated with certain expenses.
