1. CDM : Poultry litter based
power generation
Clean Development Mechanism: An Update
IGES-ICS workshop
Bangalore, 26-27 July 2005

2. Project brief
“Recovery of methane from poultry litter by
high rate biomethanation process and grid
connected power generation”
Purpose
To collect, process and recover methane generated by
poultry litter
To generate electricity from methane and sell to state
owned utility
To produce organic manure from the biogas digester
residue.
To demonstrate environment friendly technology to avoid
emissions and to enhance propagation of
commercialization of such technology
To contribute to the positive sustainable development of
the region: socially, environmentally and economically

3. Project brief
Promoters : G. K. Bioenergy Pvt. Ltd.
Capacity : 1.5 MW / 40 t of manure/day
Location : Namakkal, Tamil Nadu
Quantum of litter collected : 200 tons/day
( from 12 farms housing 1.5 Mn birds)
Technology: High rate biomethanation
(imported technology – indigenized)
Commissioned : Jan-Feb 2005

4. Current practice
Open dumping, removed
every six months
methane is generated due
to uncontrolled anaerobic
digestion besides nitrous
oxide.
Unhygienic conditions for
egg laying birds
Sold as manure to Kerala
after six months

5. Proposed intervention
Collection of poultry litter every 3-4 days
well-constructed and properly maintained sheds with
a sloping floor for easy collection of litter in bins
Adequate space or gap is provided between the
sloping floor and the poultry shelter for facilitating
litter collection.
Anaerobic digestion of collected litter for methane
generation
Power generation from methane
Manure production from the treated litter

6. Proposed intervention
Feed
Poultry Waste Digester
preparation
Dewatering
of sludge Residue
Biogas Biogas

storage desulphuration
presses tank
Power Electricity
generation to grid
Aerobic
Compost

7. CDM and the project
Project qualifies under
small scale CDM (Type III
D : Methane Recovery Litter production in
poultry farms CO2
and Type I D : Power
supply to grid) Gas released into
atmosphere
Open dumping for
six months
Land application as
manure
Avoids Methane, Carbon-
Emissions due to
di-oxide and Nitrous CH4 transportation of
semi digested litter NOx and CO2
oxide emissions (manure)
Nitrous oxide emission
reductions and CO2
reductions (for replacing
chemical fertilizer) to be
ascertained at later stage

9. Emission reductions
Methane recovery part
6,000/ annum
Power recovery part
10,000 / annum
Methodology for other ER being explored by
the promoter

10. Additionality arguments
Investment barrier
Project cost : 4.6 Mn USD
Not a common practice
Continue to open dump
Project : First of its kind
HRBM for poultry litter

11. Stakeholder consultation
Study through GRDIM, Coimbatore
Poultry farm owners
Price for litter less attractive (Rs 550 Vs 700 / Ton)
Government officials
Improve hygienic conditions for birds
Rid of bad odours and vector breeding
Enhance egg laying capacity
Improved power availability
