Design Specifications

EkoLakay toilet specs: Height (with plastic seat): 21 in; Length: 20 in; Width: 15.75 in; Weight: 28 lbs

Materials: local wood, imported plastic toilet seat, locally made plastic bucket and urine gallon (all materials are purchased locally). The toilet has a 5 gallon (19 liter) bucket that is changed out each time it is full.

The waste treatment process involves transport to a composting waste treatment facility where the solid waste is covered with bagasse (a by product of sugar cane juice extraction). Over the next few days the temperature of the compost rises, effectively killing any viruses contained in the human waste. The waste is mixed with carbon matter and undergoes a rapid decomposition process for 6+ months until it is transformed into nutrient-rich agricultural compost.
