4. Fabrication of biogas plant:
From the literature review, it is found that Arti- Biogas
plant system with proper modifications is efficient in
producing biogas for cooking purpose.
The design consists of the assembly of two high
density polythene (HDPE) tanks of 1 and 0.75 m3 capacity
assembled with proper fittings. Smaller tank is the biogas
collector which is connected to a burner through a pipe
line. The two tanks are fitted with proper sealing. To
increase the surface area for the development of biofilms,
pebbles of stone is filled at the bottom of lower tank. Also,
to provide more surface area plastic mosquito net filled
with plastic waste is fitted in the digester in the vertical
position as shown in Fig 2. The plant is ready for use.
