Valuable resources can be recovered from wastewater, sewage sludge, fecal sludge and human excreta. SNV can be contracted through the inhalation of virus-contaminated deer mouse excreta. Using dry manure as a fuel source is an example of reuse of excreta. This can make the reuse of excreta contained in sewage attractive. Human excreta and food waste do not provide optimum conditions for composting. Inspection of beef and proper disposal of human excreta are also important measures. The safe reduction of human excreta into compost is possible. The percentage of medications degraded during composting of excreta has not yet been reported. This risk also extends to consumers of crops fertilized with untreated excreta. Around human habitations, they feed on a variety of food scraps and even human excreta. There is an untapped fertilizer resource in human excreta. The soil nutrients could be used as a form of reuse of excreta in agriculture. Wildebeest benefit the ecosystem by increasing soil fertility with their excreta. These factors make other types of toilets or other forms of excreta management problematic. This practice creates air pockets in the human excreta to promote aerobic decomposition.
