It may sound yucky, but definitely practical nowadays.
This Kenyan company has started turning human poops into fuel, a significant step in embarking the country in a clean energy.
The Kenya-based company has proven that not all of the human shit becomes wastes at all.
As of now, the human poop, once they reach the toilet, often end up in the sewage system for them to decay.
From the so-ordinary process, once poop leave the body they are already deemed useless. But that’s not what a Kenyan startup wants to happen for every human fecal matter – some of those they want to convert into a sustainable fuel source with the sun’s heat as catalyst.
Kenya-based company named Sanivation, is the first company to treat human poop in creating a charcoal, which began commercial operations in August 2015 after years of experimentation and testing.
According to Emily Woods, Sanivation CTO, that they can ‘treat thousands and multi-thousands of peoples’ shit continuously’.
Talking about the process, once the fecal wastes are collected from latrines, they are treated with heat to sanitize the waste and remove the harmful pathogens.
In order to do this, a 5-sq.m. parabolic disk made of glass and steel concentrates the solar energy and reflects the light to the glass side of a receiver containing the waste. The other sides of the receiver, which are made of cement or fiberglass, prevent the increasing heat of up to 60° C from escaping.
Sanivation’s target is to have all the pathogens present in the poop be removed, they can do this through heating up the poops.
As of now, it is under research, how hot really is “hot enough”; but an estimates says that the goal may achieve when the waste is heated to 60 degree celsius for an hour.
The target market of Sanivation is small businesses and restaurants which usually buy in bulk. For the said businesses, they purchased between 200 kilograms to 2 metric tons of briquettes as compared to the few kilograms bought by households.
