The easily degradable waste material mixed with wastewater from the
kitchen is fed into the plant through the inlet chamber of the plant. This waste
is converted into cooking gas with the help of a special type of anaerobic
bacteria. The main component of the gas produced is methane which is a renewable
source of energy.
The space required for a domestic plant (1 Cum) is one square
meter. Time required for the installation is 1- 4 hours, depending upon the
model of the plant. The gas generated from the waste of a family of 3 -5 members
is sufficient enough to work a single burner stove for more than 2 hrs everyday.
The return on investment of a domestic bio waste treatment – bio
energy plant is also very good. A 1 Cum plant is sufficient to save the 70% -
90% consumption of fire wood or other cooking fuels every day. With in 2 years
the entire investment will be got back as cooking gas and liquid fertilizer. The
benefit from the methane emission reduction is another added advantage.
