INTRODUCTION
To promote Solid Waste Management at the
household level.
To contribute in reduction of Global
Warming.
To reduce dependency on LPG for cooking
purposes.
To promote an alternate source of energy
(Biogas).

What is Bio Gas?
Practically produced as landfill gas (LFG)or digester gas by anaerobic breakdown of
wastes.
During the process, an air-tight tank transformsbiomass waste into methane producing
renewable energy that can be used for heating,
electricity.

Bio Gas Plants
CLASSIFICATION-
Digesters can also be vertical and horizontal
displacement types depending on theorientation of digester.
The horizontal plants are suited for high
ground water level or rocky areas.

SCRUBBING UNIT
Scrubbing unit is a device which is used to
remove unwanted residues from the methane
gas.
This helps in achieving purified methane
which has got higher Calorific Value.
