Collecting human waste in the slums is a daily challenge for slum people. The government is not providing good sanitation solutions. Every day the collectors push their carts through the muddy streets, unprotected. They can only dump the waste straight into the sewers coming in Nairobi river. It is causing a great health risk. Recently there was an outbreak of cholera in Kibera slums. And it is polluting the environment. Some firms come up with solutions, like the Fresh life toilets. Here human waste is collected with saw dust and converted into organic fertilizers. The product is sold to Kenyan farmers. And it’s cheap: only 3 Ksh per person (0,03 E).
