Design Specifications

The TFP composting toilet design relies on a horizontally mounted rotating drum, much like a garden composter, that sits inside a box. Following use, individuals cover waste with saw dust or dry leaves, spin it once a week. Natural aerobic decomposition eliminates dangerous pathogens and foul odors. It also reduces the volume of the waste by 80% so the user only needs to empty the drum out once every 2 months. After emptying, TfP suggest users dig a hole a foot deep, bury the compost with wood ash as a disinfectant and cover it with dirt. The compost can also be used as fertilizer for planting trees for cash crops or reforestation.

The TFP Composting design specifications are: – Weight, 70 pounds – Dimensions in inches, 18W x 29L x 23H – 7.5 gallon drum and 5 gallon bin capacity. ^{Interview with representative}
