The TFP Composting Toilet

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}

Toilets for People provides training and technical support to their NGO customers. Those implementing NGOs then provide technical support to end users. Toilets for People interacts directly with end users on occasional field visits. ^{Interview with representative}

The TFP Composting Toilet requires two months active composting of waste in its drum, after which composted waste is removed by user to a hole nearby where it is covered in wood ash and dirt. A tree can be planted in the compost hole. The toilet has a 10-year life expectancy.^{Interview with representative}
