Use of Human Waste in Terra Preta Biochar?

We lead in the implementation of dry toilets that dehydrate feces (to kill pathogens) and divert urine to containers. The human waste is then mixed in our Terra Preta - Biochar initiative. Why? This is to re-use human waste in agriculture and close the loop between sanitation and food security. Urine contains nitrogen and feces contains phosphate, major elements for the plants. Excellent solution to poverty, poor sanitation and malnutrition in the rural areas!
