Methane -v- wood/kerosene/charcoal

Even if KCIS could design a very cheap anaerobic digester, would Kenyan women adopt it as a cooking fuel?

Wood and charcoal are traditional fuels, and I believe that Kenyans follow their traditions unless they are given a very good reason not to.

So, if KCIS did develop a very cheap anaerobic digester, would anyone use it?

OK, dear reader, please discuss!

    What happens with the digested sludge?

    Like this Biogas latrine in Kibera. It looks nice and all, but what do they do with the old sludge? Discard it into Nbo river?

    I think it will be much easier to handle wood and fuel than biogas, so unless maybe we find a suitable storage system that allows the use of biogas somewhere else (= in gas containers), it will not be accepted as an alternative.

    Hi jke
    The digested sludge makes excellent, liquid and solid, disease-free, odour-free fertiliser – as long as it is fully digested. The anaerobic process generates enough heat to kill pathogens, so I have read. I am not a biologist or chemist, so I have to take the word of those who know for now. But I will find out soon. Our digester has been going for almost 6 months, the usual lifetime of a tankful.
    I will be reporting on the state of the sludge when we carry out a re-fill.
    The Kibera latrine should also be producing fertiliser.
