The local water company collects poop from latrines and septic tanks. Then it dries it in the sun. Then it its it to 300°C and adds sawdust. Finally molasses is added to the product as a binder.
There are 3 big problems this product helps to mitigate. First, one major problem in the developing world is people cutting down trees to make fuel for cooking (not the only reason of course that trees are felled). One of the big wins and easy ways of cutting emissions would be to stop deforestation.
Related to this is the use of paraffin or open fires to cook on. Both create respiratory disease problems due to the release of particulates and paraffin obviously has a oil dependency. This product is being sold at a competitive price with these.
The last problem is that of health due to the spread of faecal bacteria.
One claim made about biochar is that its carbon negative (if you read the Monbiot article above you can see this could vary). This product cannot be carbon negative since it involves heating to high temperatures and the addition of plant based products. Nevertheless it seems to me press a number of the right buttons. Another alternative that is going on all over the developing world is the use of poo to make biogas.
