Biogas is a value-added product comes from anaerobic digestion of organic compounds. The most common biogas production is done in large capacity which required large area and high cost to be operated. In order to benefits the consumer on the biogas production, varieties of innovated household biodigester machines were introduced.This portable household biodigesterappeals to the rural to provide economical and alternate source of energy apart reducing the organic waste dumping to landfill. Biogas produce consists of methane gas which can act as an alternative for cooking gas at home. In the meantime, effluent obtained at the end of anaerobic digestion can be used as fertilizer. Moreover, the cost of production is cheaper and easier to be operate. The size of portable household biodigesters varies in range of 1 to 150 m3 with common designs such as fixed dome, floating drum, plug flow type, and balloon type.This review paper aims to bring a further understanding on the design, capabilities and limitation from different type of household biodigester that have been used.
