Organic Farming Part II – ‘Cow dung to biogas’
A new more colourful film on biogas, see https://youtu.be/N_JBavF726Q
Like many organic farmers, Jose Elanjhimattam is both a practical and abundantly resourceful man. Starting with cow dung, Jose has created an ingenious system that simultaneously captures and separates nitrogen-rich organic manure and methane gas. Unlike dried cow dung, which tends to lose nitrogen throughout the drying process, the liquefied organic manure produced through Joses slurry provides soil with far higher levels of nitrogen. Additionally, the methane gas removed is used as a form of fuel. Jose estimates that the dung from two cows is sufficient to provide enough biogas to support the cooking requirements of a family of four. Resourceful, intelligent, simple great stuff!
