90% methane. These gases can be compressed and liquefied; therefore, biogas can be
purified by using various techniques. Mostly target is to remove H 2 S which is
present as impurity, and in impure form methane cannot be used as vehicle fuel
and also presence of water can be harmful for the compressor. Mostly technique used
for purification of biogas is water scrubbing, membrane separation and biofilters,
chemical absorption, and pressure swing absorption. Sweden is a world leader in the
production of transportation fuel in 2012. India is trying hard to achieve the goal and
trying to upgrade the production of biogas. The most common technology to purify
methane is water scrubbing.
Simple anaerobic procedure leads to conversion of biomass into biofuel energy
and manure, which enhances the financial and social improvement of farmers.
Socially, methane production from cow dung or other kinds of dungs and waste
rice plants is harmful for the environment, since it is a greenhouse gas and by
properly using it for cooking, electricity production, or vehicle fuel, we can reduce
and can manage air pollution (Mittal et al. 2018).
A family type biogas plant generates biogas from organic substances such as
cattle, dung, and other biodegradable materials such as biomass from farms, gardens,
kitchens and night soil wastes, etc. The process of biogas generation is called
anaerobic digestion (AD). The following are the benefits of the Biogas technology.
It provides clean gaseous fuel for cooking and lighting. Chemical fertilizers can be
done away with since the digested slurry obtained from the biogas plants can be used
as enriched biomanure. It is good for the climate and for sanitation problems since
toilets can be linked directly with biogas plants.
Biogas can be used as clean energy fuel, since it finds applications in running
vehicles and in cooking, heating, and electricity production. According to a report
from cattle dung of 304 million cattle, around 18,240 million cubic meter of biogas
can be obtained per annum (Kadam and Panwar 2017). Now, India is focusing on
clean energy production due to which various plans have been implemented in the
past few years.
5.3
Barriers in Biogas Production
After extensive literature review, the following barriers may be accounted for biogas
production:
1. Low percentage of methane and its production
2. Costly
3. Laborious
In addition to these above factors, in India, various other problems exist, which
have been discussed in detail in Mittal et al. (2018) (Table 5.1).
