3. What is Biogas ?
Biogas is a form of renewable energy produced by anaerobic digestion.
It is a mixture of gases, It consist of around 55-65% Methane,
30-35% carbon dioxide, 1-5% water vapor, and 0-3% hydrogen sulphide.
but this will depend upon the digester feedstock.
In order to produce Biogas, we need a bio-digester and bio waste

Introduction

4. Anaerobic digestion (is an oxygen-free environment) is the man-made device
to harnessing the anaerobic fermentation of wastes and other biodegradable
materials using Biodigester.
BIO DIGESTER
R & D P R E S E N T A T I O N F E B 2 2 , 2 0 1 6 Slide 4
Anaerobic digestion can occur at mesophilic (35-45˚C) or
thermophilic temperatures (50-60˚C).

5. Biogas formation
The four key stages of anaerobic digestion involve
1.Hydrolysis
2.Acidogenesis
3.Acetogenesis
4. Methanogenesis
The overall process can be described by the chemical reaction, where organic material such as
glucose is biochemically digested into carbon dioxide (CO2) and methane (CH4) by the
anaerobic microorganisms
C6H12O6 → 3CO2 + 3CH4

6. The widespread availability of bio mass has motivated me to investigate
alternatives towards sustainable energy developments.

17. Methodology
Slide 17
Hybrid Dustbin has been designed indigenously and engineered to
operate using a continuous process mode, suitable for mesophilic
and thermophilic temperature conditions, high vs. low portion of
solids, and multistage gas scrubbing techniques with collection of
gas in flexible cylinder.

Benefits
R & D P R E S E N T A T I O N F E B 2 2 , 2 0 1 6
Provides a scientific way for disposal and/or processing of kitchen wastes.
Produces a large amount of methane gas which can be stored at ambient
temperature.
Produces free flowing, almost clear liquid odorless effluent, which can be added
to compost or used as fertilizer.
Rodents and flies are not attracted to the end product of the process. Access of
pests and vermin to wastes is limited.
Closed cycle process which eliminates the need of extra area

20. Conclusion
R & D P R E S E N T A T I O N F E B 2 2 , 2 0 1 6 Slide 20
HYBRID DUSTBIN is the most promising scientific
disposal active device will address the current municipal
waste management issues related to segregation of
garbage at source faced by state governments. The
biogas produced can be used to supplement the fuel
requirements of the kitchens that generate the kitchen
waste and by product good quality biofertilizer will be
used for agriculture to avoid use of chemical fertilizer
