Poultry farmer Aram Uprajong in Western Thailand had a choice. Either close his farm or restore the friendship with his neighbours. Wisely he chose for the last. Over the years the manure of his 6,000 layer hens caused heavy problems with odour and flies for the neighbouring villagers. In response to the increasing complaints Aram installed a bio-digester, thus preventing a forced closure of his farm. After satisfying his farm and own family’s energy needs, Aram now distributes the surplus of biogas free of charge to dozens of houses in the village. The villagers only pay a small maintenance fee to use the plastic-piped local grid. The digestate is sun-dried and sold as fertilizer. But most importantly: the bad odours as well as the flies are gone! And last but not least, the captured methane from the manure substitutes the fossil fuel used in many households before.
