The bio-digester hub is designed as a repositionable kitchen island, including a chopping surface with vegetable waste grinder, a gas cooking range, a glass tank that shows energy reserves and glass elements showing pressure, volume and readiness of compost sludge. Materials used in the design are copper, cast iron, glass and bamboo.
‘Bio-gas’ is produced by developing a culture of suitable bacteria living on organic waste material from the home. The gas the bacteria generate is collected and burnt. This arrangement is called a methane digester and it has been used in various configurations for centuries.
The gas from the methane digester in the Microbial Home is fed to a cooking range and gas mantle lights. Water pipes are preheated by the digester and channeled to other components in the Microbial Home system. The digester needs a constant supply of waste material and water. The dehydrated sludge residue from the digester can be safely removed and used as compost.
