Dheenabandhu is a commercial bio-gas plant with digesting chamber where manure, from cows ,humans, and chicken ferments to provide biogas, through the release of methane.  Biogas is seen as a clean fuel, and provides a feasible alternative to cooking gas.  In colder climates like the lower regions the Deenbandhu fixed model is ideal because the digestion chamber is underground providing good insulation against the cold.    The plant is constructed underground, protecting it from physical damage and saving space. While the underground digester is protected from low temperatures at night and during cold seasons, sunshine and warm seasons take longer to heat up the digester. No day/night fluctuations of temperature in the digester positively influence the bacteriological processes

The main feature of a Deenbandhu biogas plant is the fixed underground digester chamber, constructed with a layer of bricks and an additional layer of cement mortar forming the roof above. Connected to the underground chamber is an inlet tank (labelled on diagram as “Mixing Tank”), through which manure is fed into the plant. The manure then ferments separating the slurry from the methane gas which rises and collects at the top of the digester tank, and is released through the gas outlet pipe. The slurry passes into the outlet tank where it is ejected from the plant and can be used as fertilizer on the field
