Hi All- I'm involved in a school exchange project between my school in Wales and our partner school in Lesotho. They have requested information about small scale biogas production, to help produce cooking gas for the school kitchen I believe. Currently they cook for 700 plus students and staff daily using firewood. Needless to say this has a serious effect upon the local trees as well as the schools finances.
I have absolutely no expertise in this field and don't really know where to start. FWIW, they have hole in the ground/ long drop toilets. They keep three or four pigs too, fed on food waste.
I'd really like to be able to help these guys- but I'm needing help myself
