Design Specifications

The Blue Box toilet design includes a wooden base created to fit locally available containers for urine and fecal collection. The top is a hinged wooden top that allows access to replace waste containers. This top can be locked closed for safety. A plastic toilet seat is attached to the hinged lid. The urine diverter is created from shaped and cut sheet metal to fit required sizes for comfortable and effective use. Twice a week a Sanivation toilet service representative services every customer toilet in their respective households. In servicing the toilet, service representatives place a lid on both the urine and feces containers. These are removed through the hinged lid of the toilet. New empty, clean containers are replaced in the toilet. Feces containers are lined with plastic bags.^{Interview with representative} Collected waste is transported to Sanivation's work site where the feces is transferred into re-purposed metal paint drums, which are attached to large parabolic mirrors that act as solar energy concentrators. Concentrators heat the feces to a high enough temperature to inactivate pathogens and transform it into a sticky substance that can be used as a binding agent for a non-wood-based charcoal briquette. This process is illustrated below.
