Biogas offers several advantages, utilizing biological waste and reducing CO2 emissions. MUH is a biogas digester designed for isolated alpine pastures locations where cowherds spend long periods taking care of their animals. This digester offers them the chance to utilizes cow dung as fuel to produce independently the gas needed for their daily life, such as cooking, heating, lighting and so on. MUH is composed of a rotomoulded main body and an inflatable gas tank, that works simply by inserting dung on a daily basis, which releases methane through anaerobic fermentation.
