Abstract—This paper reports a systematic study regarding comparison of construction material of biogas digester. Indian government as per data is promoting the use of domestic biogas plant in rural and urban areas of country. In the current scenario prefabricated biogas plants (PB) are rather preferred over the tradition cement concrete plants .Basically two main types of digesters are available in the market made of High-Density Polyethylene (HDPE) and Fiber Reinforced Plastic (FRP).In the present work analysis has been done practically on the digesters to depict the material type which serves the purpose efficiently. Various parameters and tests such as tensile test, strength to weight ratio and temperature retaining capability of material were considered during the research work. Three specimen of variable thickness were taken under consideration for tensile test according to ASTM Standard D 638. Highest peak load of 2441.9 N with elongation of 7.9 mm was obtained for FRP Specimen of 4mm thickness. Strength to weight ratio of FRP material with thickness of 2.7mm was at the higher side giving value of 6.06 Temperature retaining capability serves better platform in case of FRP material which further helps in growth of methanogens and hence biogas production. The outcome of the present work suggests the use of FRP tanks in place of cement, HDPE and other materials for the production of biogas.
