The biomass generated after digestion can be used both as animal feed and to improve soil fertility. Co-digestion of pineapple waste with cow dung appears to be a promising approach for bioenergy recovery. The results showed that co-digestion of cow dung with plantain peels as co-substrate reduced start-up time for biogas generation and increased biogas yield by 18% as compared to cow dung alone . Purification of the produced biogas was carried out by passing the gas through three chambers containing 40% KOH, CaO.activated charcoal . The biogas generation in the plant was nearly 250 L. Furthermore, as the OLR increased to 4 kg VS/m 3 d, the volume of biogas produced further increased to 1100 L. This was due to stabilization of the process. Biogas digesters are most efficient when working on organic waste with a neutral pH. The minimum specific energy needed to improve biogas production was estimated at about 7500 kJ/kg TS. First and Foremost, cow dung is mixed with water and conveyed to a biogas digester i.e. The major composition of biogas is methane (CH 4 ) 50- 70%. Anaerobic digestion is a microbial process for production of biogas, which consists of primarily methane (CH4) & carbon dioxide (CO2). process of fetching biogas from cow dung via anaerobic digestion. The volume of Biogas generated was less compared with the past studies conducted under sunlight (out door). Bioigniter produces biogas, which makes it a very valuable fuel source in rural areas, where manure or cow dung is used as a fuel. What is the need for biogas production? In order to help you figure out which types of manure and food waste will yield you the most biogas, we have compiled this simple guide. The research exposed further that cow dung as animal waste has large possibilities for production of biogas. 200kg cow dung waste biogas plant has been manufactured for acquiring cow dung biogas. The decrease was more observed in the cow dung slurry experiment as it recorded acidic at 4 th day than the combined waste slurry which recorded acidic at 12 th day. 7. The machine can not only provide biogas from cow dung but also produce biogas from other food wastes. Imam et al. Sheep What is biogas? The pH value of the cow dung and food waste was initially measured and adjusted to nearer to neutral and gradually increased to acidic and again it got stabilised to the neutral pH which favoured the production of biogas. The objectives of the . greatest electronic albums of all time Anaerobic co-digestion (AcoD) has been practiced for decades to convert waste into value-added energy products, especially biogas.
