 INTRODUCTION

• Biogas typically refers to a mixture of different gases produced by the breakdown of organic
matter in the absence of oxygen.
• The main source of raw material for production of biogas is Plant and Animal biomass .
• It is a renewable energy source.
• Biogas is primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of
hydrogen sulfide (H2S), moisture.

 Biogas : Indian scenario

• India has installed 4.75 million small scale biogas plants. India has potential maximum
number of biogas plants has been estimated to be 12- 17 million .
• Mainly biogas is produced based on dairy manure as feed stock and these "gobar" gas plants .
• Some Examples of Biogas Plants in India are:
• India’s largest biogas plant is situated at Methan village in Sidhpur tehsil of district Patan in
Gujarat

 Biogas production plant and its components

• The Main parts of a typical biogas plant consist of the following components:-
 Inlet
 Digester
 Gas holder
 Outlet
• There are different types of biogas production plants. The main two types are as follows:
.Fixed-dome Plant .Floating-drum Plant

 Objectives of the study

 To study biogas and its production with selective waste products of different types as
feedstock along with the technique that is used in the production.

 To study about different initiatives taken by the Indian government.

 Schemes allotted by Indian Government for biogas production

i. Gobar-dhan scheme
 This program was launched in
April 2018 by Union
Ministry of Drinking Water
And Sanitation.

ii. STAT
 This program was launched in October
2018 and was launched by Shri
Dharmendra Pradhan.

1.Municipal Solid Waste

S.NO. TITLE AUTHOR YEAR COMMENTS

1. Biogas production optimization Llano et al., 2021 When MSW is employed, the best
by anaerobic digestion of biogas yield is obtained, however
municipal solid waste. when various feedstock’s are co-
digested, the highest calorific
value of biogas and electrical
power potential is obtained.
Creation of biogas from food Karimi et al., 2019 The use of additives, frequent
2. waste and the management of feeding, and feedstock pre-
municipal solid waste. treatments were only a few of the
techniques used to improve the
biogas production process from
food waste.
3. Biogas production by using the Prakash et al., 2015 The study resulted in the
municipal waste that is present in production of biogas from waste
huge amount of quantity. present in abundant quantity to
fulfill the need of energy
requirement off industry and
residential area .

4. The anaerobic digestion process Priadi et al., 2013 Which resulted in the
of paper sludge which was production of methane of near
mixed with the cow manure about 269 ML/g by the use of
only paper sludge.
5. Production of cattle manure Chakravrthi 2002 This article examines a
biogas and energy generation functional model of a biogas
plant and its economic
usefulness as an alternative
energy source.

6. The effect of wastepaper on MOMOH et al., 2008 The amount of wastepaper put
biogas production from the co- to a fixed quantity of cow dung
digestion of a given amount of plus water hyacinth was varied
cow dung until the maximum biogas
production was obtained.

7. Anaerobic digestion of fruits and Wanath et al., 1991 The result included the major yield
vegetable processing wastes for of gas of about 74.5% within 24
the production of biogas. days only. Therefore, we can see
that the usage of the waste can be
used as feedstock for the production
biogas .

8. Utilization of agricultural wastes Meggyes 2012 biogas generation took place and
for biogas and energy Production was portrayed as an alternative
by the use of different agricultural agricultural system for a livestock
waste. farm, by developing versions that
met the energy and waste disposal
goals at the same time.
9. The case of large farms is taken Bitir et al., 2001 Biogas can meet the farms' energy
into consideration needs. For maintaining the energy,
environmental, and economic
balances, special software has been
developed. Biogas as a source of
heat and power is the greatest
option.

 CONCLUSION

• Although renewable energy power generation is a genuine clean development success story,
there are some problems that need to be addressed to make the industry sustainable and self-
supporting.

• Biogas offers a vast set of benefits.

• Considerable government involvement is required for these support network to be continued
