Abstract Biogas is one of the renewable energy resources produced from the anaerobic fermentation of biomass. About 60% of Pakistan population live in rural areas that demand energy source for domestic and commercial use. Therefore, biogas plants can be used as one of the renewable energy sources in Pakistan. This paper described the development and performance evaluation of small size household portable biogas plant. The lightweight double-ply polypropylene material is used to fabricate the biogas plant, which is durable and easily portable. The volume of the digester was 2.15 m3, and the gasholder volume was 0.84 m3. The performance of the developed plant and biogas production is verified by three different treatments of feeding materials, i.e., buffalo dung (BD), buffalo dung plus sheep waste (BD + SW), and buffalo dung plus chicken droppings (BD + CD). The maximum biogas productions for treatments BD, BD + CD and BD + SW were recorded 0.59 m3/kg-VS, 0.61 m3/kg-VS, and 0.79 m3/kg-VS, respectively. The AMPTS was also conducted to compare total methane production. The nutrient analysis performed for both substrate and slurry showed improved nutrient quantity in the slurry. The cost estimation cleared that fixed biogas plants have 1.27 times more costly than that of portable biogas plants. The developed biogas plant is favorable for its light in weight and low cost, and it can produce enough methane gas to fulfill the domestic requirements. Keywords Portable biogas plant .

1 Introduction The world is facing an energy crisis and climate change environmental problems. The increased need for energy with the development of industry also makes it necessary to find more energy sources. Energy sources are usually divided into two groups: renewable and non-renewable. A non-renewable

resource is a resource that does not renew itself like fossil fuel, nuclear fuel, and natural gas. Renewable resources are generally defined as energy that is collected from resources that are naturally replenished such as sunlight, wind, biogas, and biomass. Renewable energy can reduce our dependence on
