Biogas is a natural gas used for kitchen and other heating purposes, produced by the biological breakdown of organic matter in the absence of oxygen.
Biogas is generated by anaerobic digestion or fermentation of biodegradable materials such as Buffalo Dung, biomass, manure, sewage, municipal waste, green waste, plant material and wasted crops. The gas pruduced is primarily methane and carbon dioxide.
Biogas can be used as a low-cost fuel in any country for any heating purpose, such as cooking. It can also be used in modern waste management facilities where it can be used to run any type of heat engine, to generate either mechanical or electrical power. Biogas can be compressed, much like natural gas, and used to power motor vehicles too.
In Pakistan and India biogas produced from the anaerobic digestion of manure in small-scale digestion facilities is called gobar gas; it is estimated that such facilities exist in over two million households in India and in hundreds of thousands in Pakistan, particularly North Punjab, due to the thriving population of lifestock .
What is Biogas
The digester is an airtight circular pit made of concrete with a pipe connection. The manure is directed to the pit, usually directly from the cattle shed. The pit is then filled with a required quantity of wastewater. The gas pipe is connected to the kitchen fireplace through control valves. The combustion of this biogas has very little odour or smoke. Owing to simplicity in implementation and use of cheap raw materials in villages, it is one of the most environmentally sound energy sources for rural needs. One type of these system is the Sintex Digester. Some designs use vermiculture to further enhance the slurry produced by the biogas plant for use as compost.
How it works
Wasandi Bio Solar Energy (Pvt) Ltd has vast experience in implementing BIogas Plants in Pakistan. Wasandi Bio Gas Plant is ispired by the most efficient and modern mechanising of China & Sweden.
Gas produced with Wasandi Bio Gas plant is clean oddorless and has been successfull used in CNG Electricity generators also.
